Estimating Body Fat Percentage
Body fat percentage is often a better health indicator than weight alone, because it reflects body composition rather than just mass. This calculator uses the US Navy method, which estimates body fat from simple tape measurements of your neck, waist, and hips.
Healthy body fat ranges differ by gender. For men, 14–24% is typical; for women, 21–31%. Athletes usually fall lower. Use a flexible tape measure and measure consistently for the most reliable estimate.
