Clinical takeaway
Mosteller is the most widely used BSA formula.
When to use
Dose calculations that are normalised to body surface area.
How it works
Mosteller BSA(m²) = √(height(cm) × weight(kg) / 3600).
Key points
- Mosteller is the most widely used BSA formula.
- Du Bois and other formulas give slightly different values.
- Dose capping policies may apply for very high BSA.
