Abstract
The results from the present study inidicate that the equation of Dubois and Dubois (1916), now in common use for estimating body surface area, is not the most accurate of those available. Our new equation is based on the measurement of body weight and upper calf circumference only. It accounts for a large percentage of the toal variance (88.9%), and has a low standard error of estimate (0.05 m2), which suggests that this equation may be more useful in the estimation of human body surface area than many of the equations previously produced. Direct comparisons of the accuracy of other workers' equations is difficult to assess due to the different methods by which the equations have been produced and expressed. We do not advocate the use of different equations for males and females because the data indicate that the present equation probably applies equally well to both sexes.
