Wingspan

The wingspan is the distance from one end of a wing to the other. We often talk about wingspans when we think of birds or airplanes. For example, the Boeing 777–200 airplane has a wingspan of about 61 meters. Birds can also have very large wingspans. The biggest living bird, the wandering albatross, can have a wingspan of more than 3 meters.

Wingspans are important because they tell us how big an animal or airplane is. They also help scientists and engineers understand how well something can fly. Birds with longer wingspans are often better at gliding, and airplanes need long wings to stay steady and lift off the ground. The term wingspan can also be used for other flying animals like bats and even insects.

In people, the word wingspan is sometimes used to describe something called arm span. This is the distance from the tip of one arm when it’s stretched out to the tip of the other arm. For most people, their arm span is very close to their height.

Wingspan of aircraft

The wingspan of an aircraft is measured in a straight line from one wingtip to the other.

The size and shape of wings matter for both animals and aircraft. Bigger, heavier animals and planes need larger wings to stay in the air. This depends on both the length and width of the wings. Long, narrow wings help with smooth flight, which is why birds like albatrosses and big airplanes have them. Shorter, broader wings work better for quick turns and easy maneuvering, like in fighter jets or birds that catch insects. These help with quick movements and flying close to the ground.

Wingspan of flying animals

The wingspan of a bird is the distance from the tip of one wing to the tip of the other wing when the bird is lying flat on its back. To measure it, the wings are held at the wrist joints and the distance between the longest primary feathers is measured.

For insects, the wingspan is measured in pinned specimens. It can be the distance from the center of the body to the tip of the wing, doubled, or the width between the tips of the wings when they are set with the trailing edge perpendicular to the body.

Wingspan in sports

In basketball and gridiron football, players' wingspans are measured from fingertip to fingertip. This measurement is also called reach in boxing.

For example, a young basketball player named BeeJay Anya had a very long wingspan of 7 feet 9 inches, even though he was not yet 7 feet tall. Another player, Manute Bol, had the longest wingspan ever recorded in basketball history, measuring 8 feet 6 inches.

Wingspan records

The wingspan measures the distance from one wingtip to the other. Some of the largest wingspans belong to the Scaled Composites Stratolaunch aircraft. The extinct Pelagornis bird also had a very large wingspan, as did the Hatzegopteryx pterosaur.

On the smaller end, the Starr Bumble Bee II biplane has a tiny wingspan. The Nemicolopterus pterosaur was also very small. Even some tiny insects, like the Tanzanian parasitic wasp, can have very small wingspans.
