Estimate body fat percentage using the U.S. Navy circumference method
The U.S. Navy circumference method is generally accurate within 3-4% of DEXA scan results for most people. It is widely used by military organizations worldwide for fitness assessments.
Healthy body fat ranges vary by age and gender. For men, 10-20% is generally considered healthy; for women, 18-28%. Athletes typically have lower percentages.
Women naturally have higher essential body fat for reproductive health. The Navy method accounts for this by including hip measurement and using gender-specific formulas based on large population studies.
