| Age Group | Male Max | Female Max |
|---|---|---|
| 17–20 | 20% | 30% |
| 21–27 | 22% | 32% |
| 28–39 | 24% | 34% |
| 40+ | 26% | 36% |
This is an estimate using the standard circumference-based method and may differ from an official Army tape test performed by a trained evaluator. Not a substitute for official body composition assessment.
How the Army Body Fat Calculator Works
The US Army estimates body fat percentage using circumference measurements of the neck and waist (and hips for women), combined with height, in a logarithmic formula.
Formula
Women: BF% = 495 ÷ (1.29579 − 0.35004 × log10(waist + hip − neck) + 0.22100 × log10(height)) − 450
All measurements should be in inches for this formula.
Army Body Fat Standards
Maximum allowable body fat percentage increases with age. Soldiers exceeding the standard for their age and sex may be required to enter a body composition program.
Frequently Asked Questions
How accurate is the Army tape test?
It's a reasonable field estimate but less accurate than methods like DEXA scans or hydrostatic weighing. Measurement technique significantly affects results.
Where should I measure my waist for this test?
The Army measures the waist at the point of the natural waist, typically at or near the navel, while standing relaxed.
What happens if I exceed the Army body fat standard?
Soldiers who exceed their age and sex standard are typically enrolled in a body composition improvement program and may face administrative action if they don't show progress.
