The Army body-fat method
Uses circumference-based equations that differ for men and womenThe method estimates body fat from tape measurements at the neck and waist, with hip circumference added for women, using sex-specific equations.
It is a field method: quick and repeatable, but less precise than DEXA or hydrostatic weighing, so treat results as estimates.
Frequently asked questions
Why measure the neck?
The neck helps account for upper-body lean tissue, improving the estimate alongside waist size.
Is it accurate?
It is good for screening and tracking, but not a laboratory measurement; small tape errors change the result.
Does it apply outside the military?
The math works for anyone, but pass/fail standards are military-specific; consult your own guidelines.
