Comprehensive comparison of different BSA calculation formulas for medical professionals and researchers
Body Surface Area (BSA) is the measured or calculated surface area of the human body. It is widely used in medicine, particularly to calculate drug dosages and assess metabolic processes.
Different formulas have been developed to calculate BSA, each optimized for specific populations or body types. Our calculator offers multiple formulas to provide the most accurate results for different individuals.
Body Surface Area calculations are used in various medical applications:
Each formula has been developed for specific populations and use cases. Here's a detailed comparison:
BSA = 0.007184 Γ Height^0.725 Γ Weight^0.425The original and most widely used BSA formula, developed from measurements of 9 subjects.
Suitability: General adult population, widely accepted standard
Limitations:: Less accurate for very obese or very thin individuals
BSA = β(Height Γ Weight / 3600)Simplified formula that's easier to calculate and widely used in clinical practice.
Suitability: General population, preferred for ease of calculation
Limitations:: May be less accurate for extreme body types
BSA = 0.024265 Γ Height^0.3964 Γ Weight^0.5378Developed specifically for pediatric patients and infants.
Suitability: Children and infants, pediatric medicine
Limitations:: Less validated for adult populations
BSA = 0.0003207 Γ Height^0.3 Γ Weight^(0.7285 - 0.0188 Γ log(Weight))Complex formula that accounts for non-linear weight relationships.
Suitability: Research applications, complex calculations
Limitations:: Complex calculation, limited clinical use
BSA = 0.0235 Γ Height^0.42246 Γ Weight^0.51456Developed for cancer patients receiving chemotherapy.
Suitability: Cancer patients, chemotherapy dosing
Limitations:: Specific to cancer patient population
BSA = 0.008883 Γ Height^0.663 Γ Weight^0.444Developed specifically for Japanese populations.
Suitability: Asian populations, Japanese patients
Limitations:: May not be accurate for other ethnicities
BSA = 0.007241 Γ Height^0.725 Γ Weight^0.425Early formula similar to Du Bois, developed for Japanese patients.
Suitability: Historical reference, Asian populations
Limitations:: Limited modern validation
BSA = 0.000975482 Γ Height^0.655 Γ Weight^0.441Modern formula based on 3D body scanning technology.
Suitability: Modern applications, high accuracy
Limitations:: Limited clinical adoption
For general adult populations, the Du Bois or Mosteller formulas are most commonly used and widely accepted.
For pediatric patients, the Haycock formula is specifically designed and recommended.
For specific populations (Asian, cancer patients), consider the specialized formulas developed for those groups.
The choice of BSA formula should be based on the patient population, clinical application, and institutional preferences. While differences between formulas are usually small, selecting the appropriate formula can improve accuracy for specific use cases.
