The BSA formula

There are many ways to calculate the body's surface area. By default, our BSA calculator uses Du Bois as the most popular form. However, there are many BSA formulas. These include the Du Bois formula, Haycock, Gehan, George, Boyd, Takahira, and Shuter for both men and women. You only need your height and weight to use any one of these formulas. Let's look at some of them.
These are the formulas.
  • Du Bois: BSA = 0.007184 * weight0.425* height0.725
  • Mosteller: BSA (m²) = SQRT{{ [ height (cm) x weight (kg)] / 3600 }}
  • Haycock: BSA = 0.024265 * weight0.5378* height0.3964
  • Gehan and George: BSA = 0.51456 * weight* height042246
  • Fujimoto: BSA = 0.008883 * weight0.444* height0.663
  • Takahira: BSA = 0.007241 * weight0.425* height0.725
  • Shuter and Aslani: BSA = 0.00949 * weight0.441* height0.655
  • Schlich (women): BSA = 0.000975482 * weight0.46* height1.08
  • Schlich (men): BSA = 0.000579479 * weight0.38* height1.24
  • Calculating the BSA

    Our BSA calculator is the easiest way to determine your body's surface area. To solve the equation, you will only need your height and weight. Once you have entered these values, the tool will automatically return a result.
    Let's look at our previous example.
  • Weight in kg: 60
  • Height in cm: 170
  • These measurements give you a body surface area of approximately 1.68 square meters.
    It is helpful to have an idea of the average BSA value in order to calculate your BSA. They can be divided into gender and age categories.
    The average body surface area is for:
  • Infants: 0.25 m²
  • Children under 2 years old: 0.5m²
  • Children under 10 years old: 1.14m²
  • Women: 1.6m²
  • Men: 1.9m²
