How It Works

This calculator uses the following formulas to calculate Body Surface Area (BSA):

• Mosteller Formula: BSA = 0.016667 × W^0.5 × H^0.5
  (Mosteller RD. "Simplified calculation of body-surface area". N Engl J Med 1987; 317:1098.)
• Du Bois Formula: BSA = 0.007184 × W^0.425 × H^0.725
  (Du Bois D, Du Bois EF. "A formula to estimate the approximate surface area if height and weight be known". Archives of Internal Medicine 1916; 17(6):863-71.)
• Haycock Formula: BSA = 0.024265 × W^0.5378 × H^0.3964
  (Haycock GB, Schwartz GJ, Wisotsky DH. "Geometric method for measuring body surface area: A height-weight formula validated in infants, children and adults". J Pediatr 1978; 93:62-66.)
• Gehan and George Formula: BSA = 0.0235 × W^0.51456 × H^0.42246
  (Gehan EA, George SL. "Cancer Chemother Rep" 1970; 54:225-235.)
• Boyd Formula: BSA = 0.03330 × W^{(0.6157 - 0.0188 × log₁₀(W))} × H^0.3
  (Boyd, Edith. "The Growth of the Surface Area of the Human Body". University of Minnesota, 1935.)
• Fujimoto Formula: BSA = 0.008883 × W^0.444 × H^0.663
  (Fujimoto S, et al. "Studies on the physical surface area of Japanese". Nippon Eiseigaku Zasshi 1968; 5:443-50.)
• Takahira Formula: BSA = 0.007241 × W^0.425 × H^0.725
  (Takahira H, et al. "Studies on the physical surface area of Japanese". Nippon Eiseigaku Zasshi 1968; 5:443-50.)
