What is Body Fat Calculator?

Body fat percentage shows how much of your weight is fat. It tells you more about your health than weight or BMI alone, because muscle weighs more than fat.

What this tool does

Uses the U.S. Navy tape method, which needs your height, neck and waist (and hips for women), and then shows your estimated body fat and a fitness category.

How to use it

  1. Choose male or female.
  2. Measure your height, neck and waist (and hips) in centimetres.
  3. Read the estimated body fat.

Did you know?

  • The tape method is usually within a few percentage points of more exact methods, but it is only an estimate.
  • Measure your waist at the navel and keep the tape snug but not tight.
