BMI & BSA Calculator

Calculates Body Mass Index and Body Surface Area for medication dosing and risk stratification.

Clinical Utility

Body Surface Area (BSA) is frequently used to index cardiovascular parameters (e.g., left ventricular mass index, aortic root size, cardiac index) and for precise dosing of certain medications, particularly in heart failure and oncology.

The Mosteller formula is preferred due to its simplicity and accuracy across a wide range of body types.
