What is propeller diameter?

A prop's diameter represents the distance across the circle created by a spinning propeller, as measured to the extreme outer edges of the blades' cutting swath. Diameter is generally referenced first when noting a propeller's size (e.g., 14.5' x 28' references a 14.5' diameter propeller).
