What Is Body Fat Percentage?
Body fat percentage represents the proportion of your total body weight that comes from fat tissue. Unlike BMI, it provides a clearer picture of body composition by distinguishing fat mass from lean body mass.
This calculator estimates body fat using the U.S. Navy Body Fat Formula, one of the most widely used methods for estimating body composition from body measurements.
How to Measure Correctly
- Measure your neck just below the Adam's apple.
- Measure your waist at the narrowest point or around the navel.
- Women should measure the widest part of the hips.
- Keep the tape snug but not tight.
- Stand naturally without holding your breath.
Why Body Fat Percentage Matters
- Provides a better picture of health than body weight alone.
- Tracks real fat loss during weight-loss programs.
- Measures improvements in body composition.
- Helps identify obesity-related health risks.
- Useful for fitness planning and athletic performance.
