Body surface area(BSA)

The body surface area is the measured or calculated surface of a human body. Because of the complexity of direct measurement, various formulas have been developed to estimate the body surface area over the years. Using these BSA formulas, body surface area will be figured out in square meters.

Body Surface Area Formulas
  • The Mosteller formula

  • One commonly used formula is the Mosteller formula, published in 1987.
    BSA (m²) = ( [Height(cm) x Weight(kg) ]/ 3600 )½
  • The DuBois and DuBois formula

  • BSA (m²) = 0.20247 x Height(m)0.725 x Weight(kg)0.425
  • The Haycock formula

  • BSA (m²) = 0.024265 x Height(cm)0.3964 x Weight(kg)0.5378
  • The Gehan and George formula

  • BSA (m²) = 0.0235 x Height(cm)0.42246 x Weight(kg)0.51456
  • The Boyd formula

  • BSA (m2) = 0.0003207 x Height(cm)0.3 x Weight(g)(0.7285 - ( 0.0188 x LOG10Weight(g))
