How to Measure Body Frame Size

Body frame size refers to the size of your bones. Since bones are very dense, the healthy weight for a given height will depend on the size of one's bones. For example, a person with small bones will have a lower healthy weight range than a person of the same height who has large bones. The most common way to measure your frame size is to determine the circumference of your wrist, because its size is dependent on the size of the bones in your arm.
