The average arm span or wingspan for adults is approximately equal to their height. The value that is
often used is the ratio of arm span relative to height which is known as the APE index. After 15 years
of age, the normal range of arm span/height or APE index is considered to be 1-1.05 but many people
may fall outside of this range.
Interestingly, “the average ratio of arms to height in the NBA is an astounding 1.06” according to
Sports Illustrated (https://vault.si.com/vault/2012/11/05/the-case-for-wingspan). We often think about
the extraordinary height of basketball players but they often have incredibly long wingspans as well.
Both being tall and having a long wing span are advantageous in this sport. Being tall puts you closer
to the hoop for easier lay-ups and slam dunks on offense. It also helps playing defense to block shots.
It is easy to see that wingspan would also help with these offensive and defensive moves.
Other sports, like swimming, may also have advantages with a long wingspan. Some sports, like
weightlifting, may have advantages with a shorter wingspan considering there would be less distance to
lift. How does your arm span compare with your height
