Big Little Man

A Visual Pun where an extremely short character is introduced in a manner that makes them appear much taller than they actually are. Also the inverse, where someone (or something) of great size or height is made to appear normal-sized at first, or perhaps introduced in a shorter or chibi-like form.

A subtrope is Big Shadow, Little Creature, where this is done via a large shadow cast on the wall. Depth Deception is the Super-Trope -- all examples that don't involve people should go there. May involve the use of Hitler Cam. See also Mister Big.

 * At the way end of the Kirby of the Stars anime,
 * There was a yonkoma omake of Fullmetal Alchemist invoking this, in which Edward claims he's about 160 cm in height. The next panel immediately zooms out to show that he has an "antenna" in his hair and is wearing elevator shoes.
 * The first episode of Slayers doesn't give any way of determining Lina's height until she meets up with Gourrey.

Film - Animation

 * Mushu from Mulan put a lot of effort into his big entrance.
 * Monsters vs. Aliens. Susan Murphy is captured by the government after growing to a height of 49 feet 11 inches and wakes up in a large, empty room with furniture the same scale as her. At first she (and the audience) is unsure whether she is normal size or not, until she steps on a small chair and crushes it.
 * The inverse happens a short time later when a vast door opens and General W. R. Monger (tiny compared to the 49'11 1/2" Ginormica) comes out. The two glowing eyes were just the lights of his jetpack.
 * And it happened a third time when Dr. Cockroach is trying to shrink Susan back to normal with electricity. When she comes to, she sees the others standing over her and she thinks she's small again. Turns out they were just standing over her face.
 * Shrek. Our first glimpse of Lord Farquaad involves him striding dramatically along a corridor, camera focused on his face or body at a strange angle, then when the camera and scenery go still, he's revealed to be maybe half the height of the guards. The gag is repeated when princess Fiona first meets Lord Faarquaad: he arrives on horseback, propped into a sort of prosthetic armour that apparently enables his controlling the horse, and makes him look like he has normal sized arms and legs. Then arrives a guard who helps his lord dismount by picking him up like a teddy bear. Her previously favourable reaction... dies.
 * Finis Everglot in Corpse Bride is first shown talking face to face with his wife. Then the camera pans out and it turns out he is standing on a stool and is really half her height.

Frank Martin battles his way through a gang of mooks; after a disposing of them another man enters the room, shown via the standard Hitler Cam to make him look big, but in close-up so we don't see how big.

Then we see he's not just the standard big mook, but a Giant Mook One Head Taller than Frank!
 * In Ichi the Killer, Jiji is a small old man who wears baggy clothes. When a thug threatens him at the end of the film, he strips off his clothes and reveals that he's ludicrously muscled, then breaks every bone in the thug's body.

Live Action TV
"Romana: "I thought I'd try this one, but it's a bit short." (The Doctor stands up, revealing Romana is the size of a child) Doctor: "Well lengthen it then, go on." (Exit Romana.

While he's checking out his new reflection in a funhouse mirror, one of the other carnies walks up and starts a conversation.

 * The Buffy the Vampire Slayer episode "Fear, Itself" had Gachnar the Fear Demon... who is 4 inches tall. Buffy stomps him like a bug.
 * A specific version I've seen a couple of times is a woman is chatting up a man, sitting down, and then realizes he's very short when he stands up, thus inducing uncertainty over whether she should continue with him. It happened to Jessie in Saved by the Bell (she angsted about how she can't date a shorter man, because it makes her feel tall and awkward), Samantha on Sex and the City (she agrees to give him a chance, but ends up going back and forth on him, but sticks with him when she realizes he's really funny and great in bed), and Roz on Frasier (he realizes she's pregnant at the same time, and they both turn and walk in opposite directions).
 * Likewise an episode of The Golden Girls had Rose meeting a man at a bar and making a date with him, then he gets off the barstool and is revealed to be a dwarf (leading to the date becoming a huge round of Ignore the Disability).
 * Star Trek: The Original Series ("The Corbomite Maneuver"). The Enterprise encounters a alien vessel, and is able to get a video feed revealing the bridge, which shows the alien captain, Balok, to be a scowling monster that looks to be about 7 feet tall. However, later they manage to get onboard, revealing they had actually been watching an elaborate puppet show, and the real Balok is no larger than a child.
 * Done intentionally in-universe in Deep Space Nine. Bashir and O'Brien are just back from a mission that involved them being miniaturised. They stand at the bar boasting about their exploits, when Quark and Odo both note that a waitress seems oddly tall next to them, sending them scurrying away to check their height in sickbay. The waitress then stands down, off the step she'd been put on by Odo and Quark, revealing the entire thing to be a gag.
 * Doctor Who did it as a Cliff Hanger reveal in Planet of Fire, where it turns out the Master has accidentally shrunk himself to a small size, and has been directing the shapeshifter robot that everyone thinks is him from a control box.
 * In Destiny of the Daleks, Romana is trying out different bodies into which to regenerate, while the Doctor is crouched on the floor fixing K9. Romana reappears as a blue-skinned alien babe, towering over him.

They decide to ask the girls to dance - Benny will ask the tall one and Jackie will ask the short one. The girls accept and stand up, revealing that - due to how the chairs they were sitting on were designed - the "tall one" is short and the "short one" is tall.
 * The NCIS episode "Once a Hero", where Abby went to government-oriented science exhibition to look for someone who could lend her usage of a very specific device of... some kind, required to identify a particular evidence, and this trope happens, as the person at the stand is revealed to be much smaller than he looks. Abby doesn't look surprised.
 * In one episode of My Hero (TV), the main characters spend a while worrying about the dreaded (*glances around* *whispers*) Grand High Arbiter of Misuse of Power coming from Ultron to punish George for cheating in a lottery. The arbiter eventually arrives preceded by an earthquake and we see a figure in a black robe, seen from below, filling the screen and taking menacingly in a booming voice. Then we see that he's two inches tall and standing on a table. Janet squashes him.
