Frequently Asked Questions
It estimates body fat from your height and tape measurements (neck and waist, plus hip for women) using a logarithmic formula. It is quick but an estimate — DEXA scans are more accurate.
Rough guides: men 10–20% and women 18–28% are commonly considered healthy, with athletes lower. Ranges vary by age and source.
Estimating Body Fat
Body fat percentage is the share of your weight that is fat. The US Navy circumference method needs only a tape measure, making it a popular at-home estimate. Measure relaxed, at the narrowest waist and widest hip.
