Body Surface Area (BSA) & Chemo Calculator

Calculate clinical BSA with major formulas (Mosteller, DuBois, etc.) and estimate chemo drug quantities.

Clinical Patient Metrics
Standard oncologist dosage index density per body area.
Calculated Body Surface Area (BSA)
Recommended Patient BSA (Average)
1.91
Estimated Chemotherapy Drug Dose
143.4 mg
Based on 75 mg/m² multiplied by an average body surface area of 1.91 m².

Chemo Dosing Clinical Note

Mosteller is the clinical standard due to algebraic simplicity (BSA = √[ (H × W) / 3600 ]). However, oncologist guidelines may specify DuBois or Haycock for extremely short/tall or pediatric patients.
