Army Body Fat Calculator
The U.S. Army uses a circumference-based method to estimate body fat percentage for soldiers who exceed weight standards. This calculator uses the official Department of Defense formulas from Army Regulation 600-9 based on your height, neck, waist, and hip measurements.
The U.S. Army body fat estimation method, also known as the tape test, uses the relationship between body circumferences and height to estimate body fat percentage. The DoD formula is based on research showing that the difference between waist and neck circumference (and hip circumference for women) correlates well with body fat measured by more precise methods.
For men, the formula uses neck circumference, waist circumference (measured at the navel), and height. For women, hip circumference is additionally required because women carry more fat in the hip region. The measurements must be taken according to specific protocols for accuracy.
Army body fat standards (AR 600-9) set maximum allowable body fat percentages that increase with age: for men, 20% (ages 17-20) to 26% (ages 40+), and for women, 30% (ages 17-20) to 36% (ages 40+). Soldiers who exceed these limits may face consequences including enrollment in the Army Body Composition Program. While this calculator uses the official DoD formulas, it is for reference purposes only and may differ slightly from measurements taken by trained military personnel.
