Body Fat Calculator
Body Fat Calculator
Estimate body fat percentage with the U.S. Navy tape-measure method.
Estimate only, not medical advice. The tape-measure method is an estimate and can be off by several points. A DEXA scan or clinician measurement is more accurate.

How this is calculated
Uses the U.S. Navy circumference method (Hodgdon and Beckett, 1984), which estimates body density from height, waist and neck, plus hip for women. Category names follow American Council on Exercise ranges. For Other / prefer not to say, the male and female results are averaged. Everything is calculated in your browser, and nothing you enter is stored or sent anywhere.
