What is the primary method used to determine body fat under AR 600-9?

• A. The circumference (tape test) method using measurements of neck, waist (and for females, hip as part of the calculation).
• B. The BMI calculation based on height and weight.
• C. The skinfold thickness test at multiple sites.
• D. A DEXA scan.

Answer: (A)

Under AR 600-9, the primary method used to determine body fat is the circumference (tape) method. It relies on measuring the neck and waist, and for women also the hip, with those measurements entered into standard Army tables to estimate body fat percentage. This approach is favored because it is quick, inexpensive, and can be done in the field with just a tape measure, while still providing a reasonably accurate assessment for a wide range of body types. Other methods exist, but they aren’t the standard for routine Army use: BMI uses height and weight and can misclassify muscular or lean individuals; skinfold testing requires more training and multiple sites; DEXA scans are accurate but impractical for everyday use due to cost and equipment needs.
