Body Surface Area (BSA) estimates the total surface area of a person's body and is used mainly in clinical settings, most notably for dosing certain medications, especially chemotherapy drugs, proportionally to body size rather than weight alone, since BSA correlates well with metabolic processes like drug clearance.
The Mosteller formula, BSA = √((height (cm) × weight (kg)) ÷ 3600), is simpler to compute and is commonly the default in modern clinical calculators. The DuBois & DuBois formula, BSA = 0.007184 × height (cm)^0.725 × weight (kg)^0.425, dates back to 1916 and remains widely referenced. The two formulas typically produce very similar results, within a few percent of each other.
Both are widely accepted and produce similar results. Mosteller is simpler and commonly used as a default in clinical software, while DuBois is the older, historically referenced formula. For any actual medical dosing decision, follow what your healthcare provider or institution specifies.
No, both formulas are mathematical estimates derived from height and weight, not direct measurements of skin surface area, which would require far more complex methods to measure precisely.
No, this tool is for general informational purposes only. Any medication dosing based on BSA should always be calculated and verified by a qualified healthcare professional.
