Body Surface Area (BSA) Calculator

Body surface area is calculated from height and weight using the Du Bois, Shintani, and Fujimoto formulas.

What is body surface area (BSA)?

BSA is an abbreviation for Body Surface Area, which is the surface area of the human body.

In the medical field, BSA is sometimes used to determine the dosage of drugs and to determine the extent of burns.

There are several calculation formulas, among which the Du Bois formula, the Shintani formula, and the Fujimoto formula are used.

BSA is calculated by the following formula.

BSA(m²) = Height^0.725(m) x Body weight^0.425(kg) x 0.007184

BSA(m²) = Height^0.725(m) x Body weight^0.425(kg) x 0.007358

BSA(m²) = Height^0.663(m) x Body weight^0.444(kg) x 0.008883
