Body fat estimator

BMI cannot tell muscle from fat. A tape measure can get much closer. Estimate your body fat percentage with the US Navy method, and check your waist-to-height ratio.

Tape measurements

Measure first thing in the morning, standing relaxed, with the tape snug but not compressing the skin. Breathe out normally.

Enter your height, weight and tape measurements to estimate your body fat.
