The Body Surface Area (BSA) Calculator is a quick and reliable tool for determining the total surface area of the human body. BSA is widely used in medical and healthcare settings to calculate drug dosages, fluid requirements, and metabolic rates. Simply enter your height and weight, and the calculator will instantly compute your BSA using scientifically validated formulas.

🔢 Why Use a Body Surface Area Calculator?

BSA is a crucial measurement in medicine and healthcare, often used for:

✔ Medication Dosage Adjustments – Many drugs, including chemotherapy and certain critical medications, are prescribed based on BSA rather than body weight.
✔ Medical Assessments – BSA is an important factor in evaluating metabolic rate, fluid needs, and burn treatment.
✔ Accurate & Scientific Calculation – Uses standard formulas like Mosteller, DuBois & DuBois, Haycock, and Gehan & George for precise results.
✔ Fast & User-Friendly – Instant calculation with a simple, easy-to-use interface.
✔ Works for Adults & Children – Suitable for medical professionals, researchers, and individuals tracking health metrics.
✔ Mobile-Friendly & Accessible – Works seamlessly on all devices without downloads or sign-ups.

📊 How is Body Surface Area (BSA) Calculated?

BSA is typically calculated using different formulas. The most common are:

1️⃣ Mosteller Formula (Widely Used in Medicine)

BSA=Height (cm)×Weight (kg)3600BSA = \sqrt{ \frac{\text{Height (cm)} \times \text{Weight (kg)}}{3600} }BSA=3600Height (cm)×Weight (kg)​​

2️⃣ DuBois & DuBois Formula

BSA=0.007184×(Height in cm)0.725×(Weight in kg)0.425BSA = 0.007184 \times (\text{Height in cm})^{0.725} \times (\text{Weight in kg})^{0.425}BSA=0.007184×(Height in cm)0.725×(Weight in kg)0.425

3️⃣ Haycock Formula

BSA=0.024265×(Height in cm)0.3964×(Weight in kg)0.5378BSA = 0.024265 \times (\text{Height in cm})^{0.3964} \times (\text{Weight in kg})^{0.5378}BSA=0.024265×(Height in cm)0.3964×(Weight in kg)0.5378

4️⃣ Gehan & George Formula

BSA=0.0235×(Height in cm)0.42246×(Weight in kg)0.51456BSA = 0.0235 \times (\text{Height in cm})^{0.42246} \times (\text{Weight in kg})^{0.51456}BSA=0.0235×(Height in cm)0.42246×(Weight in kg)0.51456
