According to the NAEYC D. KINDERGARTENERS...... I hope this helps you! : )
The body frame takes into consideration the bone structures which vary in size for different people . Also the bone density of one person is different from another. Weight and density of bones determines the size of the body frame. There are three categories of body frames: small, medium and large frame. People with large frames have a bone structure which is much larger, while people with small frames have much lesser bone weight.
