Army Waist-to-Height Ratio Calculator

Effective July 7, 2026, Army Directive 2026-13 made waist-to-height ratio the Army's sole body-composition assessment. Divide waist circumference at the navel by height using the same unit. A recorded value below 0.550 meets the standard; 0.550 or higher does not.

The ratio is truncated to three decimal places, not rounded. Extra digits after the third decimal are discarded. For example, 0.5499 is recorded as 0.549 and meets the below-0.550 standard, while 0.550 is not passing.

The current Army procedure measures the waist at the navel and divides it by standing height. Use the same unit for both measurements. Official assessments must follow current Army measurement, confirmation, documentation, and quality-control procedures.

No. It reproduces the ratio and truncation rule, but an official result depends on authorized measurement and documentation. A first nonpassing result also requires confirmation under current Army guidance.
