US Navy Method
This calculator uses the US Navy circumference method — one of the most accurate non-invasive body fat estimation techniques, requiring only waist, neck and height (plus hip for females).
How to Measure
Measure your waist at the narrowest point, neck just below the larynx, and hip at the widest point. Keep the tape snug but not tight. Measure in the morning for consistency.
