Calculate body fat percentage using the U.S. Army (AR 600-9) method and check whether the result meets current Army body fat standards for your age group.
Measure neck circumference just below the larynx. Waist at the narrowest point (navel level).
| Age Group | Male Max % | Female Max % |
|---|---|---|
| 17–20 | 20% | 30% |
| 21–27 | 22% | 32% |
| 28–39 | 24% | 34% |
| 40+ | 26% | 36% |
This uses the same circumference-based formula as the U.S. Army. Results may differ slightly from DEXA or hydrostatic methods.
