Body Fat Calculator

The following body fat calculator uses the U.S. Navy Circumference Method where three or four body measurements are fed into a
fixed formula to estimate the percentage of your body that is made up of fat. The measurements need to be accurate to within 0.5cm
or 0.25 inches and should be taken as follows:

  • Height: taken without shoes
  • Neck: taken below the larynx sloping slightly downward at the front
  • Waist: for men at navel height, for women at the smallest point
  • Hips: (women only) at the largest point
