Enter your weight and height to calculate your BSA.
Body Surface Area (BSA) measures the total surface area of your body in square meters (m²). It’s used in medical settings to calculate drug dosages, assess kidney function (e.g., GFR), and monitor health conditions. This calculator uses the Du Bois formula for accuracy. Consult a healthcare provider for medical use.
Body Surface Area (BSA) is a key measurement used in medical, health, and fitness contexts to assess an individual’s body size based on height and weight. Expressed in square meters (m²), BSA provides a standardized way to calculate dosages for medications, assess metabolic rates, or adjust clinical parameters like glomerular filtration rate (GFR) for more accurate health evaluations. Our free BSA Calculator offers a quick and precise way to determine your body surface area, making it an essential tool for healthcare professionals, patients, and fitness enthusiasts alike.
Calculating BSA is particularly valuable in medical settings, where it ensures tailored treatments, such as chemotherapy dosing or renal function assessments, by accounting for variations in body size. For fitness purposes, BSA can help estimate caloric needs or monitor physical changes over time. Our user-friendly calculator simplifies the process, requiring only your height and weight to deliver accurate results instantly. It uses established formulas, such as the Du Bois method, to ensure reliability across diverse populations.
