Body Frame Size is a way to determine your body’s bone structure. It takes into account your height, weight, and wrist circumference to determine if you have a small, medium, or large frame size. The formula is as follows:
Body Frame Size = (Height in inches - 60) + (Weight in pounds / Wrist Circumference in inches) * 2.5
