Estimate your body fat percentage from simple tape measurements using the US Navy circumference method, then see which fitness category it falls into.
How it works
- Provide your height and sex.
- Measure and enter your neck and waist circumferences (and hip if female).
- The Navy algorithm will output an estimated body fat percentage.
Frequently asked questions
How accurate is the tape method?
Within a few percentage points for most people, good enough for tracking trends. For clinical precision, DEXA or hydrostatic weighing is better.
Where do I measure?
Neck below the larynx, waist at the navel, hips at the widest point. Keep the tape snug and level.
What is a healthy body fat range?
Roughly 14 to 24 percent for men and 21 to 31 percent for women is often cited as healthy, but ranges vary by age and source.
