Paediatric BSA Dose — Mosteller Formula

Calculate paediatric body surface area using the Mosteller formula (BSA = √(height(cm) × weight(kg) / 3600)) to determine BSA-based drug doses for chemotherapy and medications where dose/m² is specified.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate paediatric body surface area using the Mosteller formula (BSA = √(height(cm) × weight(kg) / 3600)) to determine BSA-based drug doses for chemotherapy and medications where dose/m² is specified

Each component has a specific meaning:

  • Mosteller formula × weight / 3600)) — The mosteller formula × weight / 3600)) recorded for the scenario being assessed.

Note: Interpret the paediatric bsa mosteller result against the thresholds and context described above.

How to Use

Enter the Mosteller formula × weight / 3600)) for the scenario you are assessing. Calculate paediatric body surface area using the Mosteller formula (BSA = √(height(cm) × weight(kg) / 3600)) to determine BSA-based drug doses for chemotherapy and medications where dose/m² is specified. Use the paediatric bsa mosteller result to inform your calculation.
