Frequently Asked Questions
What are the Army body fat standards?
Under AR 600-9, maximum allowable body fat rises with age. For males it is roughly 20% at ages 17-20 up to 26% at 46+; for females roughly 30% at 17-20 up to 36% at 46+. Always verify against current regulations.
How is the tape test performed?
The neck is measured just below the larynx, the waist at the navel for men, and waist plus hips at the widest points for women, each to the nearest half inch or centimetre.
Can I fail height-weight but pass the tape test?
Yes. Soldiers over the screening weight table are referred to the tape test, and passing it means they meet body composition standards without further action.
