The Doctor: Well, Sergeant? Aren't you going to say 'it's bigger on the inside than it is on the outside'? Everybody else does.

Sgt. Benton: Well, it's ... pretty obvious, isn't it?

An unusual fact of some architecture in fiction is that no matter how small it is on the outside, on the inside it can be any size it darned well pleases. Walk into what looked like a phone booth (or police call box) and you're in a space that dwarfs most Gothic cathedrals.

This trope can appear in two ways:

  • Without any explanation whatsoever. Often this is used as an intentional sight gag, but equally it may be done for technical reasons, such as in early Video Games, where fixed-size background tiles may cause furnished interiors to become larger than the plain exterior suggests.

Compare with Clown Car Base, which is when we never see the inside. Also compare Units Not to Scale, Perspective Magic. Often overlaps with Alien Geometries. A subtrope is Oh Look More Rooms, in which rooms keep opening up further and further in, rather than blowing you away with a giant hall on first glance. See also Hammerspace for the variant where there is more storage on the inside.

Curiously, it is exceedingly rare to invert this trope's literal phrasing, and exclaim "It's smaller on the outside!"

Examples of Bigger on the Inside include:


Anime

  • The heroes of Jo Jos Bizarre Adventure Part 5 use a turtle. Yes, a turtle. Its Stand ability, Mr. President, allows people to enter a separate space within its shell. It's got a fridge and a bathroom in there, too, something which the characters comment on.
    • It has a fridge, but no bathroom. If I remember correctly, they have to use that zipper ability to use a bathroom.
  • Mahou Sensei Negima
    • Kaede has one of these inside her Invisibility Cloak. You put it over your head, it collapses onto the ground and vanishes, and you find yourself in a comfortably large house.
    • The same holds true for Evangeline's Resort.
    • As are the Gateports in Mundus Magicus.
  • Somewhat parodied in Ouran High School Host Club, when they went over to Haruhi's house, or at least the dream before it. Haruhi in the dream was about to open a closet, and Tamaki tried to cheer up the rest of the group, and probably himself, by saying "Inside that closet must be an infinite space"
  • Tenchi Muyo
    • Washuu's laboratory. It's accessed through a doorway under the stairs at Tenchi's house, but Word of God says the laboratory covers five planets.
    • Jurai's treeships generate pocket dimensions as living space for their crew.
    • In the TV-series, Tenchi Universe, she gives the bathroom the same treatment. Apparently, they decided that the floating, bubbled, hot-springs island from the OVA was a tad too showy.
  • Lala of To Love Ru seems to be able to do this, turning a closet into a mid-sized lab, expanding an already existing room to 5 times normal, while someone was in it, and later building a three bedroom flat on top of the main character's house.
  • Ah! My Goddess' Skuld created one of these to provide extra storage space for some of the motorcycle club's gear. Unfortunately, the control got accidentally reset -- stranding Keiichi and Belldandy in the center of an infinitely large room. And Bell was temporarily without her powers... Keiichi finally realized the crawlspace under the building wasn't within the field, so they pulled up a portion of the floor and crawled out.
  • Gluttony's stomach in Fullmetal Alchemist. It Makes Sense in Context. Father wanted to make a quick and cheap access to the Gate of Truth... And created a more or less bottomless Pocket Dimension instead.
  • The peach sennin's table-top garden box in Inuyasha, where all his "disciples" live and work. Also Yourei-Taisei's home is both a small shack under a bridge and a massive paradise. And of course, there's Naraku, who was bleeding gigantic voids after he first absorbed Moryoumaru and whose body was the second to last battleground. The actual last battleground also counts, as it was the inside of the Shikon no Tama itself.
  • There was an arc in Ghost Hunt where the main characters were investigating a labyrinth-like mansion that seemed to be much smaller on the inside, and had become the source of many disappearances. It turned out that a separate section of the mansion expanded far underground.
  • The title Mobile Suit Human of Kemeko Deluxe
  • The Death Room in Soul Eater, at least in the anime. It definitely has walls (which look like the sky complete with clouds, and can be broken) but the distance to them differs dramatically when Asura and Shinigami fight.
  • Leliel from Neon Genesis Evangelion at first appears to be a floating orb, quite large but not all bigger than Ramiel. It's true form is then revealed to be the shadow, which expands to cover most of Tokyo-3. Even this form, however, is still Smaller On The Outside, as Leliel is actually a pocket universe. Yep, a 2D shadow is actually a universe-in-miniature. I think that wins the Bigger on the Inside prize.
  • In Howls Moving Castle, the castle's door links to buildings that are sometimes smaller than the castle's size.


Comic Books

  • Nextwave hung a lampshade on this with the Shockwave Rider, which is noted by the heroes that its interior is larger than its exterior. This is played with in the final issue, where "the thing that makes the ship bigger on the inside than it is on the outside" is destroyed and the heroes have to escape before they are crushed.
  • Reed Richards of the Fantastic Four has often set up rooms like this. When the team was living in Pier 4, this was lampshaded with a comment about borrowing technology from his weird doctor friend.
  • In Mighty Avengers, Hank Pym has been revealed to have one as well, using size-altering Pym Particles to hide an entire giant laboratory with multiple floors and huge rooms... all inside a single closet. Amadeus Cho immediately compares it to the TARDIS.
  • In Buck Godot: Zap Gun for Hire, the nearly omnipotent Prime Mover "lives in his own little world.... He keeps it in his quarters." Actually, it doesn't look all that little.
    • He's terraforming his own planet, by hand. With a shovel. And filling an ocean with a bucket that also fits this trope. "You just need the right bucket."
  • The 1980's comic X-Thieves (short for "Aristocratic Extraterrestrial Time-Travelling Thieves") had the protagonists ride around in a "TARDIS-40 space yacht." Despite being able to use a standard New York City parking space, this was shown to have (among many other things) a planetary surface, or at least a significant chunk of one, inside it.
  • In Fables, the business office of Fabletown is bigger on the inside than out: it's indicated that nobody knows the full extent of the complex, although this is because the actual office is somewhere unknown and the building acts as a portal. They recently lost the building, and those inside the office are still trapped.
    • Fables also has the very important 'Witching Cloak' which can store much inside it's folds, one of it's many powers. (Careful; the weakness is it's still a cloak and can be yanked off like any other).
  • In Runaways, the Steins do their mad science in a spacious laboratory that looks like a small shed on the outside. Nico suggests that it might be a hologram.
  • Doctor Strange and his Sanctum Sanctorum. Of course, he's a wizard so...you know.
  • Elf Quest's Palace of the High Ones may be bigger on the inside, though it's never stated explicitly.
    • Also, in the Shards storyline, the "tallest tower" in Gromuhl Djun's fortress actually has the lowest elevation because there are more floors below ground.
  • One of the comics about Cubitus shows the eponymous dog passing through several chambers of an opulent palace... and eventually emerging from his ordinary doghouse.


Fairy Tales

  • In the 5th-8th century Slavic myth of the witch Baba Yaga, her tiny hut is magically, on the inside, like a great hall.
  • One of the stories in A Thousand and one Nights has a tent like this.
  • Older Than Print: This features in Celtic myth, where anything remotely like a door can be a doorway into a much bigger place. So the door to a tiny hut can well open into a large hall.
  • In Japanese folktales, Kitsune can create realms, turning a hole under a floorboard into a small estate, and turn a small field into a kingdom.


Film

  • In Star Wars, the Millennium Falcon interior is significantly larger than the exterior, mostly in regards to headroom. Due to the "cramped" interior, this is seldom noticed by the fans, even when toy models blatantly reveal this discrepancy. Hence, it requires no actual explanation. The difference is most visible when you see the Falcon docked in the Death Star. Compare it to the nearby Stormtroopers. Then compare its size earlier when they are all gathered in the lounges, and then take into account all the other rooms in the Falcon that are seen only in The Empire Strikes Back. The trope is compounded when you consider that the ship is supposed to be a freighter, with a lot of cargo capacity.
    • That's it! The ship was made Bigger on the Inside to give it more storage space.
  • Loaded Weapon 1 parodies and lampshades this with Colt's trailer. Looks rather tiny from the outside, but is big enough to contain multiple rooms and columns on the inside. He explains that he picked the colors to make it look bigger.
  • Parodied in Freaked, where Skuggs keeps his collection of "freekz" in an outhouse that is somehow positively enormous on the inside; even the moon carved into the door becomes huge.
  • Spice World featured a magically huge bus with room enough for all the Spice Girls to have their own personal living areas the size of a studio apartment.
  • A variation is seen in the Beatles movie Help. Each of the Fab Four enter into what appear to be four consecutive row houses. Turns out the four doors lead into the same huge bachelor pad.
  • Magical Mystery Tour ends with the entire cast filing into a little tent, inside which is a gigantic movie-musical set.
  • In the Charlie Kaufman film Synecdoche New York, a playwright creates a life-sized mockup of his home city inside a warehouse to use as the backdrop of his play. Naturally the set includes a life-sized mockup of the warehouse, which has another life-sized city inside.
  • In the Aliens films:
    • In Alien, the Derelict might qualify, since the egg chamber looks larger than the ship as seen from the outside. It's either this or what we know as the Derelict is just a small section of a much larger vessal that's buried underground.
    • In Alien, marines stand comfortably upright inside a transport vehicle, but are taller inside than when standing next to the thing.
  • Subverted in Bill and Teds Excellent Adventure. The time machine they are given is a phone booth that they comment is "smaller on the inside". (Could they be making fun of something?)
  • Parodied in The Man With Two Brains: Dr. Necessiter's place appears like a tiny apartment from outside and like a spacious medieval castle from inside.
  • Flatspace technology in Ultraviolet can not only be used for disproportionate storage of materials, but can also make the inside of a trailer large enough to house a laboratory.
  • The movie Crossworlds, given that it's about parallel dimensions, takes full advantage of that. Many times somebody enters what seemed to be a small room or something similar, only to be greeted by a space reminiscing of a big warehouse.
  • In the (still animated) beginning of Enchanted, Giselle gets out of her coach in her wedding dress, and Nathaniel is run over by all the animals that were apparently in the coach with her (even though her dress is so big, it's hard to tell how she fit herself).
  • The interior sets for the Discovery in 2001: A Space Odyssey are 50% too large to fit into its spherical command module. This is surprising considering Stanley Kubrick's reputation for perfectionism.
    • In 2010: The Year We Make Contact, the Leonov's interior sets aren't even remotely the right shape to fit into its hull. Peter Hyams apparently wanted all of the rooms to be interconnected on the same level in order to film Walk and Talk shots.
  • In Jurassic Park, when Grant and Sattler enter their trailer, from the outside it's simply a camper that looks like it barely has enough headroom. Once inside, it's as big as a double-wide, and the ceiling extends a good 2-3 feet above their heads.
  • In "Mary Poppins", we see one of the earliest examples, when she opens her carpet bag and pulls out a hat stand and a large mirror, followed by a plant, and an ornate lamp. When the children Jane and Michael inspect the carpet bag it appears to be empty.
  • In "The Chronicles of Narnia" The Lion the Witch and the Wardrobe, the entire realm of Narnia is contained inside of a Wardrobe. (Technically this fits under "Literature" as well, since this was a book and a movie.)
    • Narnia is another dimension, the wardrobe is just a way of getting there.
  • In a lot of Hollywood Musicals, internal sets start off small but magically become bigger when there's an extended dance scene. One example is the cabin in Seven Brides for Seven Brothers which looks small and poky from the outside, much to Millie's dismay when she arrives with her new husband, Adam. Yet when she leads the brothers in the Goin' Courtin' dance, the main living room grows to barn-like proportions. This is subverted a little in the later external barn-raising dance scene when the barn in question only looks to be about 12ftx12ft.
  • In the Korean film Hansel and Gretel, the attic of the house stretches on for miles.


Literature

  • Douglas Adams' The Hitchhiker's Guide to the Galaxy takes this to its extreme when Zarniwoop has an entire universe in his (ordinary size) office. It's just like the real one, except that Frogstar Fighters are a different color ( and it exists entirely for Zaphod's benefit).
    • And during the reveal of that spoiler, we also find that Zaphod has been carrying around the starship Heart of Gold in his pocket, without even knowing it.
    • Also, the planet Magrathea. On the inside, it's the size of a solar system, and they build planets in it.
    • Is it really any wonder that Douglas Adams invokes this, considering he used to be a script editor or something similar for Doctor Who?
  • The protagonists of Myth Adventures lived for some time in what appears to be a small tent, but inside it's a spacious house. Because it really is the entrance to a house in another dimension. The trouble comes when they open the back door and discover where it was built...
    • This is a common practice for Devan architecture, as it's hard for a haggling merchant at the Bazaar to plead poormouth when there's an obvious fifty-room mansion behind the shop.
  • In Greg Bear's Eon, the fact that the seventh chamber aboard the Thistledown is Bigger on the Inside is proof that someone has finally understood the work of the female physicist protagonist.
  • In Bulgakov's The Master and Margarita, Woland's immense ballroom appeared behind the door of an ordinary Soviet apartment (which was previously shown to be perfectly normal); one of the characters says that this is easy to achieve when you are "familiar with the fifth dimension."
  • Played for horror in House of Leaves, in which the Navidsons' house starts out precisely 1/4" larger on the inside. The scale of this difference is where a lot of the horror comes from- the tiny difference means that it almost feels like a mistake. They could be wrong, or crazy. Turns out they're wrong. It's 5/16".
    • In many editions, the pages stick out a quarter inch past the edge of the cover. Apparently the book is also bigger on the inside than it is on the outside.
  • In Teresa Edgerton's The Grail and the Ring, Dame Ceinwen's cottage appears to be an ordinary one-room cottage from the outside, and even from the inside - except that you can never quite see the entire room from inside. When you explore the perimeter of the room, you find doors opening into other rooms, cupboards, and so on.
  • The Gay Deceiver in Robert A. Heinlein's The Number of the Beast has more space inside, obtained as a gift in Oz.
  • The "stable" in The Chronicles of Narnia: The Last Battle is tiny on the outside, yet when the characters enter, it contains the whole of "Aslan's Country". As they travel further through the land, the arrive at a walled garden on a hill, but again, once they enter they find a whole country spread out before them; an even better version of the land they came through. It is implied that there might be an infinite number of such layers.
    • The stable was unusual in this respect. Not everyone who entered found Aslan's Country - a party of dwarfs who entered it found only the very ordinary dark and grimy interior of a stable. Both alternatives coexist simultaneously, as the protagonists interact directly with the dwarfs despite perceiving a completely different world. This is perhaps more a case of Clap Your Hands If You Believe.
  • In Garth Nix's Keys to the Kingdom, this applies to pretty much everything in the House. (Not to be confused with the house.) For example, suitcases and Matryoshka dolls.
  • In the Discworld books that focus on Death, his mansion is described as having rooms of a mile or more in area, despite looking like a normal cottage from outside. Normal humans who visit Death's domain usually ignore the incredible hugeness and stand on small patches of carpeted normality in the sea of immeasurable blackness.
    • The library of Unseen University also is much bigger on the inside - like a Black Hole that can read.
      • Strictly, the Library is connected to L-Space, which connects together ALL libraries, bookshops etc, so it's more than just bigger on the inside...
    • In Sourcery the heroes transport themselves in a magic lamp which they are carrying at the same time (with the lamp also inside itself). The trick is in pulling this off before the laws of physics find out.
    • When Rincewind first sees the inside of Death's cottage, the narration comments that he's so used to this that "The way things were these days, he'd have laughed sarcastically if anyone had said you couldn't fit a quart into a pint pot."
    • Also the Temple of Bel-Shamharoth in Colour of Magic, and the Lancre Caves in Lords and Ladies. The space inside the Dancers in Lords and Ladies hangs a lampshade on this, "The circle was a few yards across, it shouldn't appear to contain so much distance."
    • Unseen University, aside from the Library, is said to be expanding constantly, especially its maze-like corridors.
    • In The Last Continent, Bugarup University has a tower that's Taller at the Top: from the bottom, and while climbing it, it only seems to be about twenty feet tall, but the view from the top appears to be half a mile up.
      • Similarly, though not played for laughs, in Patricia Mc Killip's Harpist in the Wind (third in the Riddle-Master trilogy) there's a tower with an external spiral staircase that appears to be finite in size, but when you try to climb it you'll find that the top is always the same distance above you... unless the owner feels like letting you in.
  • Several locations in Harry Potter, mostly those which are Invisible to Normals, are hidden in small spaces: Grimmauld Place, Platform 9¾, the tents the Weasleys use at the Quidditch World Cup... but this is literally because A Wizard Did It.
    • Hermione's tiny little beaded handbag in Deathly Hallows. It fits in her sock, but it contains clothes, books (many, many books), tents, and a framed portrait.
    • Arthur Weasley expands the inside of his Ford Anglia so the entire Weasley family and then some can fit inside comfortably.
    • The ability to make a location "unplottable" (i.e. impossible to be included on a map) is an interesting case. The implication is that from a map-maker's point of view the world around the building contracts to fill the empty space and the building itself then resides on a plot of land with zero area. This is related to Grimmauld Place appearing out of nowhere in the films.
  • In The Magicians, many buildings are larger on the inside, such as the house that the Physical Kids hang out in. This is explained by A Magician Did It
  • Ryhope Wood in Robert Holdstock Mythago Wood: the protagonist says he can run around it inside an hour, but when he tries to go through...Time also runs differently inside it.
  • in Halo: ghosts of onyx we see a Dyson Sphere located in the core of an earth sized planet.
  • Dr. Morgenes's home/lab/pub in Tad Williams's Memory, Sorrow, and Thorn trilogy looks like a barracks from the outside, but inside seems just a little too big.
  • Many buildings in the Nightside are like this, which is to be expected in a place where space is at a premium and so many people know magic.
  • Subverted in Callahan's Crosstime Saloon; the alien Squish's saucer is smaller on the inside than on the outside, since they haven't gotten the technology right.
  • John Crowley's Little, Big : this trope (and the title of the book) refer to both the Edgewood house and Faerie being 'bigger in the inside' (a kind of topographry one of the characters of the novel refer to as an infundibulum).
  • A Song of Ice and Fire: the Halls of the Undying are a lot bigger on the inside. The most obvious difference is a staircase leading upwards whereas the building doesn't have a tower.
  • In the Doctor Who Eighth Doctor Adventures novels, the villain, Sabbath, turns up wearing a suit which is bigger on the inside. It functions surprisingly well as a disguise, proving that although he's maybe twice the Doctor's size, he also just might have twice the Doctor's brainpower. Not only is it slimming, it allows him to unexpectedly pull out a gun.
  • The Berenstain Bears' treehouse.
  • Clothahump's tree in the Spellsinger series.
  • Solembum mentions he has seen rooms that are bigger on the inside in Inheritance.
  • The House of the Osugbo in Who Fears Death.


Live Action TV

  • The TARDIS, "up-and-downy stuff in a big blue box" from Doctor Who is the Trope Codifier.
    • It is such a recognisable example of this trope that the word 'Tardis' can actually be found in the dictionary, defined as 'something which appears to be much larger on the inside than on the outside'.
    • Also used to dramatic effect in the episode "Doomsday": The Daleks mention that the Genesis Ark will establish their dominance because of "Time Lord science". The Doctor wonders what that means, and near the climax, it's revealed that the Daleks meant this aspect of Time Lord science - the ark, though tiny, contains millions of Daleks.
    • In "Father's Day", the first clue the Doctor gets that something has gone horribly wrong is that the TARDIS is not bigger on the inside; its interior is that of the prop police call box. Then the Reapers show up...
    • Also, the UNIT command trailer in the new series (first seen in "The Sontaran Stratagem") is definitely bigger inside than out. Unlike the TARDIS, there is no in-show Hand Wave. Or maybe UNIT just copied the Doctor's tech.
      • Curiously, though the set is actually bigger, it is only so by a few feet; in the DVD extras, it is remarked that it nonetheless seems vastly larger on camera.
    • The page quote is actually a lampshading of a Catch Phrase of those seeing the TARDIS for the first time. "It's bigger on the inside!" This was being mocked as early as Doctor number 3, although Benton thought it was just too obvious to be worth pointing out.
      • Ten and Martha: "It is? I never noticed!"
      • Ten pre-empts this with Wilf, but Wilf (having never been in the TARDIS but still being used to weird stuff) just replies, "I was expecting it to be cleaner..."
      • Rory immediately deduces the inside is in another dimension, disappointing Eleven: "I like the bit when someone says 'It's bigger on the inside!' I always look forward to that."
    • Don't forget the Doctor's pockets.
    • Eleven's TARDIS, according to Matt Smith, is apparently "bigger on the inside more than bigger on the inside previously".
    • Furthermore, when he jettisons off rooms for fuel, he says goodbye to the swimming pool, the scullery, and Squash Court 7. The fact that there are seven squash courts - combined with the fact that it is supposed to be able to comfortably contain the egos of six Time Lord pilots simultaneously - implies that the TARDIS ranks in size somewhere between university campus and small neighborhood.
      • Later, in "The Girl Who Waited", he mentioned that he might have to jettison the karaoke bar. That's right, the Doctor has a karaoke bar!
    • In the Big Finish audioplay 'The Condemned', they play around a little with the companion's reaction to the interior of the TARDIS. Charley Pollard, who has traveled for some time with the Eighth Doctor, encounters his sixth incarnation. On entering the TARDIS, she comments how it's much smaller than she expected (compared to the huge, gothic cathedral look it has by the time of the Eighth Doctor). The Sixth Doctor is quite put out by this.
    • Oh, and it's not just bigger, it's a whole lot bigger. The control room you see is just a small part. More than once, the Doctor has given incredibly complex directions to reach some offscreen part of the TARDIS.
    • The interior of the TARDIS is a great deal bigger than a mall - in the NA Blood Heat she actually materialises around an entire planet!
      • Talking of malls, the doctor's dressing room, in which we see the tenth Doctor choose his new attire, resembles a very roomy clothes shop, covering a couple of floors of the Tardis.
    • The episode "The Doctor's Wife" lets us see more of the TARDIS for the first time in New Who, but that's not why its so notable for this particular trope. The TARDIS, upon taking a human body, feels that humans- and the Doctor- are bigger on the inside, and she's able to overcome the force which has taken control of her Police Box self because he's so much smaller on the inside. It's a wonderful twist which shows this trope might not just be about space.
  • The myth of Baba Yaga is parodied in The Mighty Boosh with Babu Yagu, aka The Hitcher, whose travel chest contains an entire zoo.
  • The Pylons from Land of the Lost
  • The Foundation's mobile command Semi in Knight Rider was shown to be barely wider than KITT, who was the size of a standard 1982 Trans Am, while the car was pulling into or out of it. However, once in, there was enough room for the car, quite a bit of equipment, and even a picnic in one episode. It was wide enough for both of the car's doors to be wide open with room to spare.
  • Star Trek: Enterprise: the time traveler's ship. Originally, the plan was for this episode to be an actual crossover with Doctor Who, but copyright issues and thematic questions kept that from going past the "Hey, I've got an idea" stage.
    • In Star Trek: The Original Series, the Shuttlecraft used a different model for the exterior than the interior. The interior set was big enough that the actors could walk around standing upright while in the exterior they could only stand hunched over, hence the reason they are always hunched over when they step out of the Shuttlecraft.
    • Many holodeck-plots from Next Generation belie the apparent actual size of the holodeck, as the physical characters spread out so far within its simulated environment that they'd have to be walking through walls or on conveyor belts.
  • The Egg (or Trans-Dimensional Navigation Module) in Galidor has several internal levels but certainly doesn't look like it from the outside.
  • Oscar's trash can from Sesame Street is also depicted as huge on the inside.
  • Averted on Firefly. The ship was designed from the outset to be the same on the inside as on the outside, as well as being just two continuous sets (one for each deck), to establish a greater continuity of space. The viewer will always know where they are, and how that relates to everywhere else. It helps that Serenity's a rather small ship.
  • Red Dwarf's ship-to-planet shuttle Starbug gained an implausibly large set of interiors when it became the show's home base in Series 6. This was worked into the plot in Series 7, when a paradox caused by an exploding time machine expands the shuttle's innards even further (by merging it with its future self from a mooted timeline). Among other features, the paradox-enhanced 'Bug has two miles of spacious service ducts.
    • The production team were aware of this and reduced the size of the cockpit windows on the Starbug model when they switched from physical props to CGI to compensate.
  • And lets not forget the interior of 'Thunder', the name-giving boat of the award-winning show Thunder in Paradise.
  • The Warehouse in Warehouse 13 is huge on the outside, but once you're inside it becomes the Warehouse that never ends.
  • In Engine Sentai Go-onger, The Ginjiro-go has a large-sized HQ within.
  • Full House lampshades the dynamics of the family's house in the last episode.
  • The spaceship Jupiter 2 from Lost in Space fits this trope through a case of They Just Didn't Care. In the original unaired pilot, it had only a single deck, and the external scale clues (view ports & airlock door) were proportioned to match. By the first aired episode, however, the script had added a second living deck, which obviously could not fit inside the exterior. It got worse when you considered that they had to fit the Chariot (a van sized land vehicle) inside somehow – and became ridiculous when the Space Pod and its launch bay were retconned in during the second season. The heights of the ludicrous, however, waited for a third-season episode, in which a never-before-seen third deck was added (and then instantly forgotten). To make matters worse, the “Full Scale” crash-landing-mode mock-up was not only too small, it was obviously proportioned differently from the flight model.
  • Galen's ship in Crusade looks no bigger than a standard shuttle. We are only shown a glimpse of the interior (when Gideon is rescued by Galen in a flashback), but it looks much roomier inside. Of course, given that this is a technomage ship, it makes sense (it's likely just an illusion).
  • An early 2000s Playhouse Disney show called Out Of The Box took place in a house built out of several large cardboard boxes piled together, but inside it's a large room that could never be made out of a few boxes.
  • While it's genuinely played for camp value, the Battletram in The Aquabats! Super Show! looks like a simple converted motorhome on the outside, but any scenes filmed inside give it a LOT more space than what should fit in it. It has enough space to comfortably fit a room full of partying kids, Jimmy's research lab, an expanded cockpit, a bedroom enough for the entire group, and a restroom much larger than what would normally be in a motorhome, and it STILL has enough hallway space to allow for chase scenes.


Newspaper Comics

  • Mort Walker's comic strip Boner's Ark takes place on a boat that from the outside looks like a rowing boat with a deep hull and one tiny cabin. Since it houses dozens, possibly hundreds of anthropomorphic animals (including one tyrannosaurus rex), it's obviously much bigger than that.
  • Snoopy's doghouse is probably one of the more "classic" examples. It looks standard on the outside, but contains several large, opulently decorated rooms (and the famous Van Gogh/Andrew Wyeth painting).


Professional Wrestling

  • The WWE ring seems to be this way as seen in the 2009 "Little People's Court" episode of WWE Raw where Triple H and Shawn Michaels went underneath the ring, only to find a corridor and a courtroom full of dwarves.
    • It might also explain the various times The Undertaker and Kane have creeped their way through the ring, dragging their victims through the hole and into the fires of Hell.


Tabletop Games

  • GURPS: Spaceships has a ship designed like this as a Shout-Out to Doctor Who.
  • This is the stated explanation for the Bag of Holding and the Portable Hole in Dungeons and Dragons. In an attempt to prevent game exploits, sticking one inside the other tears open the portal that leads to the Hammerspace and sucks everything in. Though some more enterprising players have used this as weapons, to the chagrin of many D Ms.
    • One Dragon write-up of Baba Yaga's hut depicted the interior this way. Justified by it being home to one of mythology's most formidable witches.
  • Most transport vehicles in Warhammer 40,000. No way 10 Space Marines fit in a Rhino.
    • I did a test. You can't even fit ONE Space Marine in a Rhino!


Video Games

  • Closely related to Units Not to Scale, pretty much every game that has ever let you enter a building displays Bigger on the Inside. Controller and engine limitations require that building internals in the vast majority of games need to be scaled up to ludicrous proportions in order to make the game playable. Buildings that look about correct scale on the outside normally have to be three or four times larger on the inside. Among many developers this is a level design principle known as 'keep it wide'.
  • Super Mario 64 has a sub-area in the level "Snowman's Land" which is reached by going into an igloo which is so tiny, Mario has to crawl to get in. But inside, it's almost 1/4 as big as the main level itself.
    • And there's the Black Room of Death inside the front wall of the castle, which is bigger than the wall is on the outside.
    • The castle levels from the original Super Mario Bros.
      • Even more so in the SNES remake, where their walls actually no longer extend offscreen.
    • The Comet Observatory domes from Super Mario Galaxy.
  • Some parts of Unreal suffer this, more or less.
  • In The Legend of Zelda Ocarina of Time, the whale-like Jabu Jabu has a sprawling dungeon inside his bizarre digestive system.
  • The village of the Weavers in Loom. Despite being simple tents (roughly as large as a pup tent), the insides are much larger. The main temple housing the Loom is a veritable cathedral. Justified, since the Weavers are capable of warping the fabric of time and space.
  • The Ebon Hawk in Star Wars: Knights of the Old Republic is noticeably larger on the inside than the outside. However, considering it is based on the aforementioned Millennium Falcon, this could be contrived as a something of an Affectionate Parody.
    • Likewise, the Normandy in Mass Effect is also larger on the inside.
  • Eientei and the Scarlet Devil Mansion in the Touhou series. The head maid of the Scarlket Devil Mansion likes to play with time and space. Eientei contains (or contained) at least one hallway whose length is impossible and whose ultimate destination is not only outright impossible but makes no sense. Since it's Eientei, there are too many ways of Handwaving its existence (supergenius doctor, eternity manipulation, insanity waves; take your pick).
    • Possibly the ultimately example is Miko's pad, Senkai. It' an infinite amount of space contained in crack.
  • Odd as it may seem, Eve Online. The containers (or "cans") that you buy on the market allow you to store, in the smallest can, 120 cubic meters (m3) worth of stuff, in an item that only takes up 100! The jettisoned containers ("jet cans") also count, as they can hold 27,500 m3 worth of items, from a shuttle that only has a 10 m3 cargohold (at worst, other ships (with the exception of the 0 m3 pod) have a 100 m3 cargohold, minimum)! (Even positing that the jet cans are collapsible, like cardboard boxes, 27,500 m3 is roughly equivalent to the capacity of the largest of the industrial haulers, heavily modified for additional cargo space.) Partly, this is Hand Waved by freight containers having a "compression field" (for the same reason, you can't put livestock, passengers and some foods in them).
  • Halo: The outside model for the Pillar of Autumn is smaller than the (inferred) distance the player has to travel in the final level. Lookit.
    • This trope is also inverted if you consider the level where you have to run from the bridge in the very front of the bow to the engine room in the stern. By that level the Pillar of Autumn is actually considerably SMALLER then the outside model.
    • The Spirit Of Fire from Halo Wars, considering the amount of resources and forces it sends down.
      • The Elephant too for that matter. you can train 40 soldiers out of it. despite the fact it looks like it can hold no more than 20, maybe 30. and even that's pushing it.
  • Same thing with the Ishimura in Dead Space. When the shuttle approaches the ship in the games opening, the model is much smaller than it is supposed to be, and probably too small to house all the games levels.
  • There's an interesting psychological employment of this trope in Earthbound. The Tenda of the Lost Underworld believe they have built a cage around the dinosaurs there, even though they are the ones actually inside said cage. Therefore, to them, the cage is bigger on the inside than the outside.
    • Earthbound itself, as well as predecessor MOTHER, also played this trope straight in the usual sense. Its sequel Mother 3, however, did a pretty good job of averting it, or at least making it not particularly egregious.
  • In God of War 2, the player faces off against a colossus statue brought to life. After finally receiving a weapon able to pierce the outside deep enough to enter it, the player and Kratos enter the statue, which is somehow several more stories tall and far larger overall on the inside. The face itself is far larger as well. In fact, the inside of the statue, compared to the inside size of the face implies the entire thing is disproportionate.
  • Every Eastern RPG ever.
    • Every single hut and shed. Sometimes inverted with castles.
    • Many games handle this rather believably if you think of the town exteriors as on a condensed scale as compared to the house interiors, or approximately 50% of full scale -- if the houses are truly as large on the outside as on the inside, the exteriors would have to be twice as large as they actually appear in-game. You notice these things if you ever try to recreate your favorite Eastern RPG town models in an environment like Minecraft.
  • Donkey Kong 64 did this a lot.
    • Most notable is K. Lumsy's island. On the outside, it's small enough that one could probably jump on top of it. On the inside, the ceiling is probably at least 20 to 30 times the height of the Kongs. Same goes for the diameter.
    • Banjo-Kazooie does this a lot as well. Most notably inside the circus tent in Witchyworld in Tooie.
  • Glint's lair in Guild Wars. On the outside, it's a single grain of sand, hidden in a vast desert. On the inside, it's a huge labyrinth filled with traps.
  • Harvest Moon is a massive offender. The player's house is always pretty darn small in all of the games (or at least the ones I've played), especially on the outside. Particularly in Magical Melody and A/Another Wonderful Life, the player's house on the outside looks so tiny that you'd think they can't possibly have any room to lay down straight. The inside, though, is more than large enough to hold a bed, a television, a refrigerator, a kitchen, a bookshelf, a storage closet, and more. This don't improve much with house size upgrades you get later on, either.
  • Nethack, Slash'EM and similar roguelikes. The full games rarely go past 5mb, but without extensive knowledge of the game or cheating and, of course, luck, you can spend an entire year trying to finish it.
  • In Starcraft, at the end, the inside of Tassadar's ship is significantly larger than it's seen on the outside. Of course, in most RTS games the buildings are churning out battle ships 5 times bigger than itself, so some distortion is necessary.
  • Marathon, Descent, and Duke Nukem 3D's game engines are based on connected spaces, not Euclidean geometry. This allows for impossible physical arrangements, like a circular hallway that must be traversed 720 degrees to get back to the starting point, a Klein bottle-shaped room, or a Mirror World in the same space as the normal level.
    • Behold this in action. Most of the level is in a closet in a room, itself in a closet in the aforementioned most of the level.
  • Averted and played straight in the second movie-based Spider-Man video game. Restaurants, diners, flower shops, banks--those are just as big on the inside as they "should" be based on the outside. The two Shocker hide-outs, however, clearly are Bigger on the Inside.
  • In Animal Crossing: Wild World and City Folk the closets in the game were capable of storing 90 items, a stark contrast to the closets in the original game which stored a measly 3. In comparison most of the buildings in the game were slightly larger than on the outside.
    • This also applies to all the buildings in the original [[[Animal Crossing]]], but not so much the storage items.
  • World of Warcraft generally averts this. Instances (that is, dungeons, but they're often not dungeons in story terms) are generally inaccessible aside from the one designated entrance, and are generally underground or in enclosed buildings, but if you go to one that's not an enclosed building and if you find a way to access them anyway you'll generally find that they take up as much space in the outside world as exists inside the instance. However, there are a few exceptions. Most notably, places controlled by mages are likely to be bigger on the inside - a notable example is the "Tower of Karazhan", which is positively palatial inside. The Mage Tower in Stormwind lampshades Bigger on the Inside by limiting the tower itself very strictly to what could be contained inside - but at the top is an explicit portal to a much larger extradimensional space.
    • The mage city of Dalaran, on the other hand, completely averts this trope: it's exactly as large as the outside suggests.
      • Except the inscription shop, it is a very large tower on the inside and only a small hut on the outside.
    • Played Straight with the Bilgewater Cartel's Town-In-A-Box, which is a box of about 1 foot by 1 foot by 1 foot, but is able to contain several buildings, multiple people, and according to quest-text, a dock and an oil rig.
  • In XIII, the submarine is absurdly large on the inside and tiny on the outside.
  • The barns in the online game Farmville. If one chooses, they are capable of holding dozens of entire buildings inside them, each much, much larger then the actual barn itself.
  • Baldur's Gate is pretty common with this. A house looks like a pathetic slum on the outside. You send somebody in (usually to loot the place) and it turns out on the inside it's got a dozen rooms and, while still being a pathetic slum, it's a pathetic slum about the size of a small mansion.
  • The Wake of the Ravager series had magic tents that were explicitly bigger on the inside.
  • The trucks in the NES version of Metal Gear. Go inside, and instantly you notice the scale have started to move.
  • Inverted for laughs in the tie-in adventure game for Callahans Crosstime Saloon. In one stage you have to hijack a friendly alien's saucer. Unfortunately it's smaller on the inside than the outside, because "his race hasn't got the technology straightened out yet."
  • In The Elder Scrolls games, it applies to a degree. While the cities are to scale (and in case of Morrowind on the overworld in their entirety) the houses inside the cities are usually bigger on the inside.
    • The Dwemer Lockbox in Septimus' Outpost is totally this. The inside of the cube is at least twice as big as the outside. Even the tunnel leading into the cube is longer than the cube itself!
  • Averted in the Gothic games. Every city and house interior is part of the overworld and exactly the same size on the inside as on the outside.
  • Blood Omen: Legacy of Kain: The structure in the center of Dark Eden, explicitly.
  • Subtler example: The map Well in Team Fortress 2 has bases that are bigger on the inside, though not very much. There's no special trick of non-linear geometry going on (the engine doesn't even support such a thing); they just hid part of the interior behind a Skybox and projected the rest of the building's façade onto it.
  • Speaking of that engine, Portal 2 has an even more subtle but much more high-tech example: they developed a method for seamlessly connecting nonadjacent areas in a level, purely to simplify the development process. When the game was being finished up, they replaced all of these links with physically-connected areas except one, a room that is imperceptibly bigger on the inside.
  • Grandmother's House in The Path. On the outside, it's a small, perhaps one-and-a-half story cottage; inside, it's impossibly tall and narrow, going up six or seven stories and containing a pair of endless corridors.
  • Ships in the X-Universe series use subspace compression technology to make the cargo bay bigger. This means that an M5 scoutship not much bigger than a modern F-16 can carry at least a dozen people in a space roughly the size of a refrigerator. The process, incidentally, is fatal to lifeforms unless an additional life-support package is installed, and it remains rather unpleasant to undergo.
  • One of the biggest changes to the rerelease of the first Quest for Glory game was the addition of this quality to Baba Yaga's hut. In the original, it's a cramped, claustrophobic space, but in the VGA remake, it's just one corner of a vast, gloomy cavern that definitely isn't there on the outside. Both quickly turn out to be scary places, but in different ways.

Webcomics

  • The Law of Purple has Red's 'magic wardrobe', which has six floors; they include such things as a weight room, large, fun devices from various planets, a teleporter, and an Olympic-sized swimming pool. Red's renting the fifth floor out to a friend of his.
  • Dominic Deegan used a spell for this early on.
  • In The Inexplicable Adventures of Bob, Viceroy's Spire on the dragon planet Butane is bigger inside than out. Molly describes it as "All tesseracty and Whovian!"
    • This becomes a plot point when the Spire is destroyed. Rather than collapsing in on itself, its pieces expand away from each other--giving Voluptua a chance to survive rather than be crushed.
  • In Finders Keepers, we have Morlock's store. Among other things, it has a sign that reads: "Morlock "It's bigger on the inside.""
  • Keychain of Creation has a wagon that works like this, because Misho knows magic science.
  • The Ambis spaceships in Jix fit this trope.
    • Possibly because the artist has no idea what the dimensions are of the ships.
  • The hospital in Superego is heavily implied to be this, along with other unsettling location tropes.
  • Hello With Cheese has a timeline for such objects -- here and here.
  • In Mountain Time, it is implied that this is a trait of an ordinary human stomach.


Web Original


Western Animation

  • In what is probably a Peanuts reference, Scooby Doo's doghouse in A Pup Named Scooby-Doo looks like Snoopy's doghouse on the outside, but is an opulent mansion on the inside.
  • The goldfish-bowl castle in The Fairly Odd Parents.
  • In "The Farnsworth Parabox", Dr. Farnsworth creates a box containing a perpendicular universe - which contains a perpendicular Farnsworth, who has created a box containing the first Farnsworth's universe. They end up swapping boxes, so they have a box that contains their own universe.
    • The Planet Express ship and the building that houses it tend to have larger interiors if the plot demands.
    • Bender's torso is often bigger on the inside, as the plot or gag requires
  • The title building from Foster's Home for Imaginary Friends
    • Possibly explained in the episode Dinner is Swerved, as the house may or may not be, itself, an imaginary friend. Madame Foster is certainly... 'creative' enough to imagine one.
    • It should be added that the house looks pretty huge on the outside, too.
  • Dexter's Laboratory, that was big enough to have "forgotten areas" resembling a jungle.
    • Averted with his rival Mandark's lab, which is actually visible behind his house, complete with an entire Death Star.
  • Pick any Hanna-Barbera show. The houses, be it the pre-fab caves on The Flintstones or the elevated apartments on The Jetsons, will look much larger on the inside thanks to Wraparound Backgrounds.
  • The title band in Hi Hi Puffy AmiYumi had a tour bus that was basically a large apartment.
  • Jimmy's "Hypercube" in Jimmy Neutron.
  • In Planet Sheen: "It's a lot roomier in here than it looks from the outside. Some would even argue that it's impossible."
  • The Clubhouse in Monster Buster Club. Decrepit childhood hangout on the outside, freakin' Area 51 on the inside.
  • The Beatles' Yellow Submarine has the band living in a place in Liverpool that's a grim little building outside, and bigger and more imposing than Versailles inside. The eponymous sub is similarly cavernous.
  • In an episode of The Magic School Bus, Ms. Frizzle turned the bus into a Suppose-O-Tron, but it seemed to retain its regular form. Then she led the class inside to reveal it now had a mammoth interior housing a gigantic laboratory.
  • In Ed, Edd 'n' Eddy, the Kanker Sister's trailer looks like a normal trailer on the outside, but inside it's a full two-story house, with staircase, large bathroom, and ginormous living room to boot.
  • In the Popeye cartoon Wolf in Sheik's Clothing Olive Oyl is kidnapped by a desert sheik and taken to his "humble abode", a tent. The tent is very small but when Olive looks inside she's shocked to find that it's a huge palace!
  • Pingu's igloo is very much like this.
  • The Ashleys' clubhouse in Recess on the outside it just looks like some old tires fused together but on the inside it has a game room, a study room, a tea party room, a TV room, etc.
  • In an episode of Phineas and Ferb, the boys build a rocket in the backyard with a control center in a small shed. The shed comfortably seats a dozen girls acting as flight control. Phineas remarks that Ferb is just really good with the layout.
  • Sharky's doghouse from Eek! The Cat; on the outside it looks like a regular doghouse, but on the inside it's a mansion.
  • The title nightclub of Disney's House of Mouse. What actually gave this away was the fact that in the show's opening credits, one can easily tell that Willie the Giant is actually the same height as the building's exterior, but when we see the main dining area, one can tell that Willie can actually fit inside perfectly, and that the House of Mouse not only has a huge seating capacity -- enough that (almost) every single animated Disney character can all fit inside the building at the same time -- but also an extremely high ceiling just so even giant characters can fit inside as well. And when the Prop Room comes into play, things get a whole lot complicated...
  • The Simpsons house remains fairly consistent on the inside (but the rooms do seem to move around as needed). It's the outside property that is 'bigger on the inside'. Bart's treehouse (which tends move around the yard) is as big as it needs to be on the inside. The backyard expands or contracts as the plot needs (such as when anti-crime cameras couldn't see it). Even the side yard expands when it needs to, such as when Bart and Lisa get into a confrontation with package delivery people.
  • Bubbie from The Marvelous Misadventures of Flapjack. She's blue and bigger on the inside.
  • The passenger planes from Cars 2.
  • Donald Duck's chalet (which for some reason resembled der Fuehrer's face) in Der Fuehrer's Face. This is most noticable during the scene where a Nazi marching band can be seen plowing into said chalet and immediately dragging Donald to the weapons factory to perform hard labor.
  • Astrotrain's interior seems to change size as the plot demands, being large enough to accomdate a fully combined Devastator with room to spare. Although Astrotrain himself changes size as the plot demands as well.


Real Life

  • Cities, towns, houses and stuff actually LOOK the smaller the more far you are. It makes this (YMMV) Truth in Television
  • Many Disneyland rides, especially the Haunted Mansion. The parks get around this issue by use of back lots hidden from public view, or making the rides partially underground.
    • It's actually a little-known fact that Walt Disney World's parks, at least, are built well above ground level, with quite a bit of theatrics going into disguising this. This elevation provides space for the dark rides like the Haunted Mansion, as well as the Utilidors that allow cast members to travel around the park without being seen by the guests. (In practice, though, it really is underground; they just made it that way by raising the ground level rather than digging down.)
  • 10 Downing Street (the official residence of the UK Prime Minister). From the front it looks like an expensive but otherwise ordinary town house with maybe a dozen rooms total. It is actually three houses joined together (one of which was a substantial mansion in its own right) and has about 60 rooms. Andrew Marr on his Sunday morning show called it "the brick TARDIS".
  • Hondas are as close to this trope as real life gets. One person said he got in and out of his new 1984 Honda Accord several times after buying it, each time walking around the car to check its size, then getting inside and disbelieving its rather large interior room.
      • The current reigning champion of space utilization is the Honda Fit. Here they 1) Made a conscious decision that there would never be an all-wheel-drive version of any vehicle on the platform, and did without a rear axle, and 2) Put the gas tank under the front seats rather than the rear seat as is typical of front-drive cars. The result is a flat load floor with the back seat down, almost a foot lower than that of a Toyota Yaris with the same roof height and about 40% more cubic volume.
    • Volkswagen Beetles also have this effect. Everybody thinks they're itty-bitty pieces of crap, but they're actually very roomy thanks to the domed shape of the Beetle, which allow things to be much bigger on the inside than they appear to be from the outside. The old Beetle also does this thanks to its rear engine leaving more than enough space in the fender available for the passengers' legs Although spread out (between the main front compartment and an often-overlooked space behind the rear seats) there is also a considerable amount of luggage space..
    • The same goes for the Smart brand of vehicles. Clever placement of engine components allows very large people to drive these very, very small cars.
    • The Renault Avantime was an inversion of this. An attempt to make a sporty car out of the base of their Espace minivan, it sacrificed room in the process despite still looking like a van. A book called The World's Worst Cars managed to describe it as "The TARDIS In Reverse."
    • Toyota Priuses manage to pull Bigger on the Inside too; you can fit a couple of fully assembled bicycles and several sacks of groceries into the trunk if you lay down the backseat. And it's a compact car.
    • Some people have vans or small trucks retrofitted into tiny homes, complete with bed, kitchen, storage space, etc.
  • Happens all the time in the world of computing. Data compression and procedural generation can pack vast amounts of output data into comparatively small files.
    • That 5MB MP 3 file you downloaded which plays for four minutes? The output audio data will probably take up about 45MB.
    • That DVD you rented with a 2.5 hour movie on it? Uncompressed, the video alone would take up roughly 280GB. The disc only holds 8.5GB.
    • That game which takes up 4GB of disk space will almost certainly throw several thousand times that much data at you over the course of playing it from start to finish. Assuming you run it at 1440* 900 pixels, get 60 frames per second, and take 20 hours to finish the game, that's about 16 terabytes of video data thrown at you over the course of the game (with probably a couple of gigabytes worth of audio thrown in as well).
    • While in a lot of applications, lossy compression will give smaller files, a smart artist can get some very impressive compression ratios with the lossless PNG format. Draw it smartly, and you can get an image more than twice the size of an HDTV frame to compress down to a few hundred kilobytes as PNG, and have the resulting file smaller than a JPEG version of the same image.
    • The Demoscene has made an art form out of this trope. There are plenty of demos which fit into just a handful of kilobytes, yet easily produce five or ten minutes of awesome trippy graphics, usually accompanied by some nice music, too.
    • And taking things Up to Eleven, there are things like the infamous 42.zip, which is a 42374 byte file that expands to around 4.5 petabytes.
      • For those who usually do not see this number, a Petabyte is 1000 Terabytes, which means that file is equal to 4,500,000,000,000 bytes.
      • The experimental drone music band Bull of Heaven also made an 85 kb zip bomb that expands to 1.3 zetabytes(1.3 billion TB). The contained "song" is a series of duplicate files whose length adds up to over 10 billion years.
    • Finally, to top even that, we have things like droste.zip, which could be considered as having an infinite size when expanded, since it contains itself.
  • The Tivoli amusement park in Copenhagen, Denmark is as close as it gets to this trope in the real life. It is an magnificent illusion of the park being far larger than the city block where it is in.
  • In General Relativity, due to the curvature of space-time, the radius and volume of massive objects are larger than one would expect given their circumference[2]. For the Sun, this means the radius of the sun is about 2km larger, and the volume of the sun is about 0.0006% larger than it would be if it were massless. That means a spherical shell built around the Sun would be very slightly bigger in the inside than an identical shell built in empty space would be(source).
    • This effect also get larger the more massive and compact the object is. Black holes are such an extreme example they may be only a few miles across, but have almost infinite volume.
    • This may be inverted, averted, or played straight on a large scale. We're not sure. If the curvature of space is positive, it's played straight. In fact, the universe would only have finite volume, and as you increase the volume of a sphere, the surface area will eventually start decreasing. This would be like building a circular fence, and expanding it until it contains more than a hemisphere, at which point the fence starts getting shorter. If the curvature is zero, it's played straight, and on large scales geometry works how you'd expect it to. If the curvature is negative, it's inverted, and large expanses of space will be smaller on the inside.
    • This also sort of happens on the surface of the Earth. The Earth is a sphere, which has positive curvature. If you trace a circle on it, and take the surface area it encompasses, it will be slightly more than you'd expect.
  • Bodies. Like yours. The human body has 21 feet of intestines inside of maybe 6 feet of human body. Thats not even getting into how many miles your circulatory and nervous systems account for.
    • Actually that is not quite true. The body itself isn't bigger on the inside than it is on the outside, but it contains extremely compressed organs bigger than itself (and even then that's using a questionable definition of the word "body" as the organs are part of it). Basically, it's like when you stuff a luggage full of clothes. It may contain things bigger than itself, but the size of the luggage remains unchanged.
  • The Hard Knocks "tactical laser tag" arena near the University of Central Florida is quite modest from the outside: a single polarized glass door with the logo and several posters advertising operating hours and special events, with the left and right taken up by generic office blocks. Upon entering you find a full internet cafe (including a military firing range simulation) and a full warehouse and office space for combat. It's not until you enter the office arena that you realize that the "generic office blocks" were also bought out by Hard Knocks and made into the arenas.
  • Related to the Disney examples above there are some cases where this can't actually be done, but it's possible to give an illusion of it with careful design. Even the choice of paint can have an effect, with bright colors tending to make a room feel bigger than it is.
  • Look at the webpage you're reading. One tiny hyperlink will lead you to thousands upon thousands of more webpages, all of them with more hyperlinks to thousands upon thousands of more webpages... all within your personal computer. The internet itself fits this trope nicely.
  • A common interior design trick, often used in stores and restaurants, is to give the illusion of this by having large, wall-sized mirrors which give the illusion of the space extending to far greater lengths than would be expected.
    • This works right up until someone walks into it.
  • President Thomas Jefferson designed his home, Monticello, to appear smaller when approaching it.

Notes

  1. And that's only one of thousands of rooms
  2. E.g. if you measured the radius of the by drilling a hole to the centre of the Earth and extending a long tape measure down, you would get a number that is about 2mm larger than the number you would get from forming the tape measure into a circle around the Earth and dividing that circumference by 2*pi
