Everyone's size and height are different, so there is no standard for different people. As long as the line proportion of the body looks smooth. Normal people's standard shoulder width should be 1/4 of height, and normal people's standard shoulder width should be 1/4 of height, or 2 heads long or 3 heads wide.
Shoulder width should be the linear distance between the peaks of deltoid muscle on both sides of the body, which is mainly determined by the length of clavicle and the development of deltoid muscle. The standard shoulder width of a normal person should be 65438+ 0/4 of the height, or 2 heads long or 3 heads wide. The subjects' legs were shoulder width apart, and they stood naturally with their shoulders relaxed. The tester stands on the back of the subject, first touches the midpoint of the lateral edge of the acromion with two index fingers along the scapular ridge, that is, the acromion point, and then measures the distance reading between acromion points with calipers. The measurement error shall not exceed 0.5 cm. Although shoulder width is mainly determined by the length of clavicle, it can still be greatly changed through deltoid exercise, but this is not a qualitative change.
