How to Calculate Frame Size

Frame size refers to the size of the bones in your body. The size of people's bones varies, so you need to know your frame size to accurately determine your appropriate body weight. For example, a person with larger bones will naturally weigh more than a person with a smaller bone structure. You can use either your wrist circumference or your elbow circumference along with your height to calculate your frame size.
