Estimating Your Body Fat Percentage
Aperçu
Body fat percentage describes how much of your body weight is fat versus lean mass — a better health indicator than weight alone. This calculator estimates it from body measurements using the U.S. Navy method, instantly in your browser. It is an estimate, not a clinical measurement.
Comment utiliser (étape par étape)
- 1
Enter your measurements
Height, neck, and waist (plus hips for women), measured with a tape.
- 2
Select your sex
The formula differs for men and women.
- 3
Read your estimate
Use it as a baseline and re-measure periodically to track the trend.
Comment ça marche
The U.S. Navy formula estimates body fat from circumference measurements — neck and waist (and hips for women) relative to height — without special equipment. It correlates reasonably with more precise methods for most people. Because it relies on tape measurements, accuracy depends on measuring consistently at the right spots; tracking the trend over time is more reliable than any single reading.
Quand l'utiliser
Tracking fat loss when the scale alone is misleading. Setting a body-composition goal alongside weight. Getting a no-equipment estimate to monitor progress over time.
Questions Fréquentes
It is a reasonable estimate for most people, typically within a few percentage points of more precise methods, as long as you measure carefully and consistently.
Notes Importantes
Body-fat estimates from measurements are approximate and for informational purposes only — they are not a medical diagnosis. Consult a qualified healthcare professional before making health or fitness decisions.
