Whats your Ape Index
Your ape index is a calculation made using your height and armspan and is most commonly expressed in inches. An example of Ape Index would be, let's say someone is 5'9" (69 inches) tall, and their armspan (the distance from middle fingertip to middle fingertip when the arms are outstretched) is 75". This person's ape index is +6. Ape index can be a negative or positive number or zero if your armspan is equal to your height.

Ape Index = Arsmpan - Height
