- Choose your units.
- Enter height and weight.
- Mosteller is shown as the main result because it is simple and widely used clinically.
Formule
BSA formulas are empirical fits to measured skin surface area. Height in cm, weight in kg, result in square meters.
Mosteller: BSA = √(height × weight / 3600)
Du Bois: BSA = 0.007184 × W^0.425 × H^0.725
Haycock: BSA = 0.024265 × W^0.5378 × H^0.3964
Example
- 175 cm, 75 kg.
- Mosteller: √(175 × 75 / 3600) = √3.6458 ≈ 1.909 m².

What is an average BSA?
About 1.9 m² for adult men and 1.6 m² for adult women.
Which formula should I use?
Mosteller is the most common in practice. Haycock was validated in children. Your healthcare team will specify the formula used for any dosing.
