How to Find Your Body Fat Percentage

 

The following body fat calculator uses the U.S. Navy Circumference Method where three or four body measurements are fed into a 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 (centimeters tends to produce the most accurate results) 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

After figuring your body fat percentage, check the charts below.

Age-Adjusted Body Fat Charts for Men and Women

If you look around the Internet, you will see a lot of different recommendations for body fat percentages. As far as I can tell, this is the most authoritative, as it is based on World Health Organization and National Institutes of Health recommendations, and takes age into account. Please do not confuse these numbers with the BMI (Body Mass Index) scores, which are not the same thing.
