Bodies are proportional. The size of one part can tell us the size of another. Here are some examples.
Wingspan = Height
(Above) Stretch your arms out wide. This is your wingspan. It is about equal to your height.
Forearm = Foot

Your forearm is the space between your wrist and elbow. Put your foot to your forearm. Are they the same size?

The bottom of your hand is called the heel. Measure from the heel to your fingertips. That is about the size of your face.
