Body fat percentage calculator
Estimate your body fat percentage with the U.S. Navy method: all you need is a tape measure and a scale, no expensive equipment.
Neck: below the Adam's apple. Waist: at the navel. Hips: at the widest point.
How to measure well
Use a flexible tape measure, without squeezing. Measure with your body relaxed, ideally in the morning. The U.S. Navy method estimates body fat from body circumferences: it's less accurate than a skinfold or DEXA scan, but it's practical and useful for tracking the trend over time by always measuring the same way.
