By the Leonard's canon the total height (H) is 8 times the measure of the head (E),and the pubes (P)
is at the center of the body,at an height of 4 E .So the total trunk lenght is equal to the legs lenght.
The shoulder's width of the body is approximately 2 E.
By the classical proportions the width of the head (C) is 2/3 E.
The waist ( and the navel N ) is placed at an height of 5 E from the base,with a width of 2 C (i.e. 4/3 E).
The maximum breadth with open arms is nearly equal to the total height H .Is the Vitruvian man :
"homo ad quadratum".
The sternum (S) is nearly located at a distance of 2 C from the top of the head.
