Body Surface Area Calculator
Calculate your body surface area (BSA) using the Du Bois and Mosteller formulas.
What is BSA?
Body Surface Area (BSA) is used in medicine to calculate drug dosages (especially chemotherapy), fluid requirements, and kidney function assessments. The average adult BSA is about 1.7 m². The Du Bois formula (1916) and Mosteller formula (1987) are the most common methods.
