Army Body Fat Calculator
Calculate body fat using the U.S. Army method.

Why Body Fat Matters in the Military
The U.S. Army uses body fat standards to ensure service members maintain optimal physical readiness. Lower body fat is associated with better endurance, mobility, and overall fitness performance.
The Tape Test Method
This circumference-based method was developed as a practical way to estimate body fat without specialized equipment. While not as precise as DEXA or hydrostatic weighing, it provides a consistent, standardized measurement.
Frequently Asked Questions
The U.S. Army uses a circumference-based method to estimate body fat percentage. This method is used to determine if service members meet physical fitness standards.
The Army method is reasonably accurate for most people, with an error margin of 3-4%. However, it may underestimate body fat in very lean individuals and overestimate in very muscular individuals.
Standards vary by age and gender. For men aged 17-20: 20%, 21-27: 22%, 28-39: 24%, 40+: 26%. For women aged 17-20: 30%, 21-27: 32%, 28-39: 34%, 40+: 36%.
For men: neck and waist. For women: neck, waist, and hips. All measurements should be taken at the locations specified in Army regulations.
