Body Surface Area (BSA)

Body surface area (BSA) can be calculated with several different formulas which all have slightly different results. The calculator below uses just a few of the formulas available.

Subject's BSA (m2):
   Mosteller:
      {{bsa_mosteller()}} = ((height (cm) x weight (kg)) / 3600 ) 0.5
   DuBois:
      {{bsa_dubois()}} = 0.20247 x height (m)0.725 x weight (kg)0.425
   Haycock:
      {{bsa_haycock()}} = 0.024265 x height (cm)0.3964 x weight (kg)0.5378
   Gehan & George:
      {{bsa_gehan()}} = 0.0235 x height (cm)0.42246 x weight (kg)0.51456
   Boyd:
      {{bsa_boyd()}} = 0.0003207 x height (cm)0.3 x weight (grams)0.7285 - (0.0188 x log(weight))
