These are as follows: each arm = 9%, the head = 9%, each leg = 18%, the back of the torso (including the buttocks) = 18%, the front of the torso = 18%, with the external genitalia making up the final 1%. The rule is not applicable to children, whose body proportions change with age (in younger children the head represents a greater proportion of the total body surface area).... rule of nines
