Select a unit of measurement and your gender.
If you are a male, measure your abdomen (horizontal at level of navel), neck (with tape sloping slightly downward in front), & height (without shoes). Enter you height, neck, and waist measurements. Finally, click the calculate button to see your estimated body fat.
If you are a female, measure your abdomen (smallest horizontal circumference around abdominal area), hips (largest horizontal circumference around the hips), neck (with tape sloping slightly downward in front), & height (without shoes). Enter your height, neck, waist, and hip measurements. Finally, click the calculate button to see your estimated body fat.
This calculator uses a formula adopted from the U.S Navy to give you a decent estimate of your body fat percentage. This is only an estimate and is not meant to replace more accurate body fat testing procedures such as DEXA scans or hydrodensitometry weighing (underwater weighing).
This calculator is generally accurate within 1-3% of your true body fat, and generally more accurate with males. Individuals who are exceptionally lean (single digit body fat % for males, teen % for females) will likely be overestimated, and individuals who are exceptionally overweight, will likely be underestimated.
