About Body Fat Percentage

Body fat percentage is the amount of body fat as a proportion of your body weight. It's a more accurate measure of fitness than BMI, as it distinguishes between fat and muscle mass.

How it's calculated:

This calculator uses the U.S. Navy method, which requires measurements of your neck, waist, and (for women) hips. It's considered reasonably accurate for most people.

Healthy body fat percentages:

  • Men: 10-20%
  • Women: 18-28%

Note that these are general guidelines and ideal percentages can vary based on age and fitness level.
