To be more precise, you can wrap a string tightly around the flat of the pulley where your belt rides. Mark the string where they overlap, then measure its length. Divide that number by 3.14.

This calculator generates an approximation of a minimum, so you'll want to Example: a 1/3 horsepower motor turning a 5" pitch diameter pulley at 1750
