What is 20 inch shoulder width?

20 inch shoulder width is a measurement of the distance between the two shoulder blades of a person. It is considered to be a wide shoulder width for most adults, as the average shoulder width for men is around 18 inches and for women around 16 inches. Shoulder width is determined by genetics and can be affected by factors such as exercise, posture, and body composition. A wider shoulder width can give the appearance of a more athletic physique and can also make certain clothing styles look more flattering. However, it is important to note that shoulder width should not be used as a sole determinant of attractiveness or physical fitness.
