Body Fat Percentage Calculator
Body fat percentage is a far more accurate health indicator than weight alone. This calculator uses the scientifically validated US Navy circumference method.
Understanding Body Fat Percentage
Healthy Body Fat Ranges
For men: Essential fat is 2–5%, Athletic is 6–13%, Fitness is 14–17%, Acceptable is 18–24%, Obese is 25%+. For women: Essential 10–13%, Athletic 14–20%, Fitness 21–24%, Acceptable 25–31%, Obese 32%+.
How to Measure Accurately
Measure waist at the narrowest point, usually at the navel. Measure neck just below the larynx. For women, measure hips at the widest point. Take measurements in the morning before eating.
More Accurate Methods
Skinfold calipers, DEXA scans, and hydrostatic weighing are more precise than circumference methods, but this calculator gives a reliable estimate within 3–4% for most people.
