What Is Body Surface Area?
It is the calculated surface area of the body. It is often clinically determined to measure the metabolic mass of the body and is less likely to be affected by fat mass. BSA measurement is important to measure cardiac index (relates heart performance to body size of the individual) (1).
How To Calculate Body Surface Area?
BSA depends on the height and weight of an individual (2).
Mosteller Formula
BSA = 0.016667 × W0.5 × H0.5
Where W is the weight of a person in kg/lbs, and H is the height of a person in cm/inch.

BSA is calculated for clinical purposes to determine the following:
- Cardiac Index: BSA determines the functioning of the heart based on body size (2).
- Renal Clearance Rate : BSA is required to determine glomerular filtration rate (3).
- The dose of chemotherapy is often determined by the BSA value. It is important to note that while BSA is the current prevalent method, it may give inaccurate results. (4).
Accuracy is essential in medicine and the body surface area calculator is one tool that helps maintain it. It considers your height and weight and guides medical professionals in developing treatments precisely for you. This calculator ensures your healing journey is backed by science and data and brings you closer to optimal health. So, the next time you receive a prescription, remember that this unassuming calculator is working behind the scenes to ensure your treatment is tailored to suit your unique needs.
