This calculator uses the US Navy Method, which estimates body fat from circumference measurements. It's accurate to within 3-4% for most people.

How to measure: Use a flexible tape measure. Keep it level and snug but not tight. Measure in the morning before eating for consistency.

Limitations: This method may be less accurate for very lean or very muscular individuals. DEXA scans provide the most accurate measurements.
