Body Surface Area Calculator
Calculate your Body Surface Area (BSA) using multiple clinically established formulas. BSA is commonly used in medicine for drug dosing and physiological assessments.
Your Measurements
Enter your height and weight to calculate your body surface area.
Why calculate BSA?
Body Surface Area (BSA) is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose tissue mass. It's heavily used in clinical settings, particularly for calculating doses of chemotherapy and determining renal clearance.
