Is WHtR the same as HtWR?

Yes for this tool. The Army acronym is WHtR (waist-to-height). Green Book may label the same calculation HtWR in product copy.

Does this replace the tape test?

Follow AD 2026-13 and your unit’s current ABCP process. This calculator only estimates the ratio from the numbers you enter.

Is this an Army body fat calculator?

No. It estimates WHtR from height and waist you enter. It does not calculate body-fat percentage and does not apply a circumference tape method. Those legacy approaches were replaced by WHtR under AD 2026-13. Official determinations stay with your unit.

Army body composition calculator (WHtR)

Use this Army body composition calculator to estimate waist-to-height ratio (WHtR) from height and waist. It is not a body-fat percentage or tape-test tool. Army Directive 2026-13 replaced legacy height-and-weight and tape processes with WHtR. Measure at the navel, then compare against the 0.55 standard described in AD 2026-13.

How to use

Measure height in inches (or convert feet/inches to total inches).
Measure waist circumference at the navel in inches, following current Army measurement guidance.
Enter both values. The tool divides waist by height and compares the ratio to 0.55.
Treat the result as a screening aid — commander and medical guidance control official determinations.

Examples

Example (illustrative): height 70 in, waist 38 in → ratio 0.543, under the 0.55 threshold on the encoded rule.

Example (illustrative): height 68 in, waist 40 in → ratio 0.588, above the 0.55 threshold on the encoded rule.
