Detailed explanation-1: -The human body is no exception: there is an inherent symmetry with many of the bones exhibiting a proportional relationship of 1:1.618. The mathematics of the human body is modeled in Leonardo Da Vinci’s Vitruvian Man, a diagram of a man with outstretched arms fitting precisely into a square.

Detailed explanation-2: -As a rule of thumb, mens’ body width should be 2 ⅓ heads, the distance between nipples on the chest is 1 head, the width of the calf muscles at the lower arc is 1 head, and the bottom of the knees is 2 heads from the ground. Women’s body width is a little smaller: 2 heads wide.

Detailed explanation-3: -The 8-head canon or 8 head unit (Hu) ratio, where the height of the head is 1/8 of the total height of the figure or the height ratio of the human figure is 8 heads tall, was used in art as an idealized adult figure standard. It originated in Classical Ancient Egypt and Greece and later during the Renaissance.

Detailed explanation-4: -ANSWER: The only part of the human body which does not grow in size from birth to death is the ‘innermost ear ossicle’ or the ‘Stapes’.
