Body Mass Index with WHO and Asia-Pacific (Asian Indian) cutoffs side-by-side, plus Body Surface Area via Mosteller, Du Bois and Boyd. All calculations run locally in your browser.
Disclaimer: This calculator is an educational reference, not a substitute for clinical judgment. BMI does not distinguish lean from fat mass and is unreliable in athletes, pregnancy, oedema and extremes of body habitus. Chemotherapy dosing should follow institutional protocols, including BSA capping where applicable. Paediatric BMI must be interpreted using age- and sex-specific percentiles, not absolute adult cutoffs.
