Frequently Asked Questions
How does this calculator estimate body fat?
It uses the US Navy circumference method, which estimates body fat from your height and neck, waist (and for women, hip) measurements. It's accurate within a few percent for most people.
What is a healthy body fat percentage?
Rough guidelines: 10–20% for men and 18–28% for women, varying with age. Athletes typically run lower; essential fat minimums are about 3% for men and 12% for women.
Is body fat percentage better than BMI?
It's more informative because it separates fat from lean mass — a muscular person can have a high BMI but low body fat. BMI remains useful as a quick population-level screen.
How do I measure myself accurately?
Use a flexible tape, measure at the same time of day, keep the tape snug but not compressing skin, and take each measurement two or three times and average them.
