The U.S. Navy Method
This calculator uses the formula developed by the U.S. Navy to estimate body fat percentage. While DEXA scans are the most accurate, the tape measure method is considered the most accessible and reasonably accurate for general tracking.
How to Measure:
- Neck: Measure right below the larynx (Adam's apple), keeping the tape flat but not uncomfortably tight.
- Waist: For men, measure at the navel. For women, measure at the narrowest point of the abdomen.
- Hips (Women only): Measure at the widest circumference of the hips/buttocks.
