Body fat percentage is the proportion of your total body weight that comes from fat. It can provide useful body-composition context alongside measurements such as body weight, waist size, fitness, and overall health.
This calculator uses the U.S. Navy method, which estimates body fat from height and circumference measurements. It is a practical estimate rather than a clinical measurement, so consistent measuring technique is important when tracking changes.
Healthy body-fat ranges vary by sex, age, genetics, and individual circumstances. The categories shown above are general adult reference ranges and should be used as a guide rather than a diagnosis.
Gradual changes to nutrition, regular resistance training, enjoyable cardiovascular activity, good sleep, and consistent habits can support changes in body composition. A qualified health professional can provide individual advice where needed.
