Free Online Body Surface Area Calculator

Estimate your body surface area (BSA) and BMI with this Body Surface Area Calculator. Ideal for clinical and health purposes.

What is Body Surface Area?

BSA is the total surface area of the human body, often used in clinical settings to estimate metabolic mass.

• Used for chemotherapy dosing and cardiac index.
• More accurate than body weight for metabolic calculations.
• Calculated using various formulas based on height and weight.

Why Calculate BSA?

BSA is used in medical settings to guide treatments and assess health.

• Helps determine accurate medication dosages.
• Used in cardiology and chemotherapy planning.
• Provides insights into metabolic needs.
