NCHS National Health and Nutrition Examination Survey (2011-2014). īoth the chart and the tables with average body surface area estimates are based on weight and height data from the U.S. Breitmann in 1932, Stevenson in 1937, Haycock in 1978, Schlich in 2010) and a discussion about their accuracy is ongoing in the medical community, but the formula used in our BSA calculator is one of the most-commonly used by medical practitioners. There are other competing formulae derived over the years (e.g. The DuBois & DuBois original formula is:Ġ.007184 x height (cm) 0.725 x mass (kg) 0.425 This is a slight variation of the DuBois & DuBois body surface area formula, derived in 1916, modified for easier calculation with height expressed in meters instead of centimeters and the results are practically identical. Below are some average values for different age groups in graph and table form. The result is in squared meters, which easily be converted to square feet, inches or yards as needed. Where height is in meters and mass is in kg. To estimate your body surface area our BSA calculator uses the following formula :Ġ.20247 x height (m) 0.725 x mass (kg) 0.425 BSA calculations are useful when determining different body characteristics, for example energy expenditure in the form of BMR, RMR (REE), RDEE, TDEE, which are in turn used when determining dietary and nutritional needs. After removing the pieces, they were cut into regular shapes allowing accurate BSA calculation.įrom these studies we have understanding of the relationship between height (stature) and body weight (mass) and a formula through which we can calculate a persons body surface area based in their weight and height. To address it, scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body. Since the body is a complex figure, making an accurate measurement of its surface is a considerable challenge. Body Surface Area (BSA) is simply a measurement of the surface area of your body.
