Calculate Body Surface Area
Our BSA Calculator helps you determine body surface area using multiple validated formulas. This is essential for:
- Medical dosing calculations
- Drug administration
- Metabolic assessments
- Clinical research
- Health monitoring
How to Use Our BSA Calculator
- Enter height (in cm or inches)
- Enter weight (in kg or pounds)
- Choose your preferred formula
- Get BSA results in both m² and ft²
- Compare results from different formulas
Available formulas:
- Mosteller formula: BSA (m²) = √((height × weight) ÷ 3600)
- DuBois formula: BSA (m²) = 0.007184 × height^0.725 × weight^0.425
- Haycock formula: BSA (m²) = 0.024265 × height^0.3964 × weight^0.5378
- Boyd formula: BSA (m²) = 0.0003207 × height^0.3 × weight^(0.7285 - 0.0188 × log(weight))
Note: The Mosteller formula is widely used due to its simplicity and accuracy. Different formulas may be preferred in specific clinical settings or for particular patient populations.
