Puny Parachute

In Real Life, parachutes are big; rarely ever less than twelve to fifteen feet across once unfurled. But in animation (and comics especially), parachutes are usually much smaller—a four to six foot diameter for example—yet somehow, they still manage to work just as well (if not better) than their real life counterparts. This also applies to airship envelopes, and for the same reasons.

This is based on the Rule of Perception, as a realistically proportioned parachute would reduce the user to little more than a dot or a line hanging from it.

A type of Balloonacy, with Parasol Parachute as a distinct subtrope. See also Improvised Parachute, which often fits this trope.

Examples of Puny Parachute include:

Film

In Aladdin, the main character jumps from a building and uses an approximately 2x2 foot scarf to soften his fall. Try that and good luck in not reducing your leg bones to shards.
Undercover Brother. When Undercover Brother falls over the edge of the cliff near the end of the movie, he floats to the ground using his bell-bottom pants as a parachute. They are much smaller than a normal parachute.
Pee-wee's Big Adventure - when Pee-Wee drives Mickey's Edsel convertible off a cliff, after several seconds of screaming, he raises the top, which balloons out a small amount and floats the two-ton car to a soft landing.
The Great Race - Professor Fate has a small pedal-powered airship - but the envelope component looks too small to lift the metal gondola framework, let alone a person - and it carries two people. Still, it looks cool.

Literature

In the first Skylark book by E. E. 'Doc' Smith, the antagonist Marc "Blackie" DuQuesne bails out from the titular spacecraft while high in Earth's atmosphere, using a parachute designed for compactness on a world with both considerably lower gravity and higher atmospheric density than Earth. While the landing isn't described, there's no indication of him requiring a lengthy stay in hospital when he reappears in the next book.

Live Action TV

Kamen Rider Fourze has a specific switch that gives him three of these. Somehow they can help him survive re-entry into the Earth's atmosphere.

Web Comics

Almost every dirigible in Girl Genius is ridiculously small for its lifting power.

Video Games

The sailcloth used by Link in The Legend of Zelda Skyward Sword to slow falls and ride updrafts; it's only about two or three feet to a side.
- The Deku Leaf in The Legend of Zelda the Wind Waker is used for similar purposes and is of similar size.

Western Animation

The Herculoids. Whenever Gloop or Gleep turn themselves into an Improvised Parachute, they're significantly smaller than a regular parachute - too small to provide the braking power they do.
Any and every Warner Brothers cartoon parachute.
Many cartoons show umbrellas being used as parachutes - the real-life consequences are shown on The Venture Brothers when Hank jumps off the roof of the compound with an umbrella (in a Batman Halloween costume), with fatal results.
One episode of He-Man shows the short-but-massive Ram-Man descending on a parachute only slightly wider than his shoulders.
The Perils of Penelope Pitstop. Penelope once used her scarf as a parachute after jumping from a plane.
