Dubois and Dubois reported an equation for estimating the surface area of a hand.

Lines of the hand with the fingers extended:

(1) horizontal along the distal edge of the radius

(2) perpendicular to line 1 to the tip of the second finger

(3) perpendicular to line 2 through the distal base of the thumb



(1) hand length in cm (from wrist to the tip of the second finger along line 2)

(2) hand circumference in cm (metacarpal-phalangeal joint circumference at line 3)


hand surface area in square cm =

= 2.22 * (hand length) * (hand circumference)


NOTE: The result appears to be about twice other estimates. This may mean that the surface area value is for both hands.
