Body Fat Percentage Calculator — 2026

Dual-energy X-ray absorptiometry (DXA) is considered the gold standard for body fat measurement, providing high accuracy. For home use, bioelectrical impedance analysis (BIA) scales offer reasonable accuracy, and the US Navy method using body measurements is another practical option.

Biological differences—including hormonal profiles, reproductive requirements, and muscle mass distribution—necessitate different body fat standards. Women naturally maintain higher body fat percentages to support hormonal function and reproductive health.

Safe and sustainable body fat loss occurs at a gradual rate, with a moderate calorie deficit combined with resistance training helping preserve lean mass during fat loss. Very rapid loss typically results in muscle loss and metabolic slowdown.

Yes. Visceral fat (stored around internal organs) poses significantly greater health risks than subcutaneous fat (stored under the skin). Waist circumference provides a simple proxy for visceral fat. The CDC recommends waist circumferences below 40 inches for men and 35 inches for women as a risk indicator.
