Calculating body frame size
Body frame size is determined by a person's wrist circumference in relation to his height. For example, a man whose height is over 5' 5" and wrist is 6" would fall into the small-boned category.
Determining frame size: To determine the body frame size, measure the wrist with a tape measure and use the following chart to determine whether the person is small, medium, or large boned.
