Body Surface Area (Mosteller)
Body surface area via Mosteller formula — most common in oncology for drug dosing
General
⚕️
Clinical reference only. Not a substitute for professional medical judgment. Verify all results against institutional protocols before clinical use.
Calculate
For clinical reference only. Confirm chemotherapy dosing with hospital oncology protocols and prescribing guidelines.
Formula
BSA (m²) = √((height[cm] × weight[kg]) / 3600)
heightHeight (cm)
weightWeight (kg)
When to Use
Used primarily in oncology for chemotherapy dosing, and in cardiology for calculating cardiac index (CI = CO / BSA).
Clinical Pearls
- •Average adult BSA is approximately 1.7 m² (range 1.5–2.0 m²).
- •Mosteller formula is preferred over DuBois in oncology due to simplicity and accuracy.
- •Use ideal body weight in obese patients for some chemotherapy agents — confirm with protocol.
