Calculate your waist-to-height ratio and compare it with Army, Navy, and Marine Corps screening rules, including how each service rounds your measurements.
Enter measurements above for a service-by-service comparison.
Service procedures record height and waist differently. Air Force waist-to-height ratio points come from the age and sex tables in the Air Force PT standards; enter the officially recorded ratio in the Air Force PT calculator. A raw ratio alone does not establish a medical diagnosis.
A raw ratio is waist divided by height in matching units. Army and Navy measurement rounding differs, so the same unrounded inputs can lead to different recorded ratios. This view shows raw arithmetic and links to the service-specific procedures.
Use the Army body fat calculator (three-measurement method) or the Navy body fat calculator (two-step BCA) for a service screening estimate. No diagnosis or universal health classification is inferred from this ratio.

The services record measurements differently before calculating a ratio. Army uses three waist readings and a three-decimal truncated result; Navy uses its own height, waist, and averaging procedure; Marine guidance uses a five-decimal rounded ratio. A raw waist divided by height is therefore useful context but is not interchangeable with every official recorded value.
No. The June 2026 Navy Guide 4 uses a less-than-0.55 first step followed by the published body-fat table process when needed. Older three-step descriptions and the previous 0.50 reference should not be applied to this current workflow. Use the Navy BCA page for its complete measurement and lookup steps.
The Air Force component uses a published scoring chart selected by age and sex. Enter the ratio recorded by your assessment team in the PFRA calculator to look up its points. This raw-ratio page does not infer the official recording precision or a complete fitness assessment from two unconfirmed measurements.
No. This tool calculates a measurement ratio and explains published service screening contexts. It does not diagnose body-fat percentage, metabolic disease, or individual fitness for duty. Measurement technique and clinical context can affect interpretation. Discuss a personal health concern with an appropriate clinician rather than treating a screening ratio as a diagnosis.
