We construct a new formula for body surface area based on geometric means. This we show, by means of Bland-Altman analysis and use of the Kolmogorov-Smirnov and Anderson-Darling tests, to be statistically equivalent to the arithmetic average of existing formulas. The result, the geometric mean formula (GMF) is the expression BSA = 0.00878108*W^ 0.434972*H^ 0.67844. We show also that body surfaces areas predicted by the GMF obey a lognormal distribution.
