How the screen works
Two-step assessment. Step 1: Waist-to-Height Ratio — 0.5499 or lower passes with no tape test required. 0.5500 or higher proceeds to Step 2: a body-fat estimate from the circumference method (neck + waist; hips for women) or official PRIMS tables.
| Initial screen | Threshold | Result |
|---|---|---|
| Waist-to-Height Ratio (WHtR) | must be < 0.55 | Below passes with no tape test; at or above → secondary body-fat evaluation |
Maximum allowable body-fat % (age / sex)
| Age group | Men (max %) | Women (max %) |
|---|---|---|
| 18–21 | 22% | 33% |
| 22–29 | 23% | 34% |
| 30–39 | 24% | 35% |
| 40+ | 26% | 36% |
Fill in your own measurements — the worksheet prints with the official thresholds above.

Reading this Navy scorecard
The sheet above is designed to be printed and carried, so it holds only what you need at the assessment: the screen, the thresholds, and the table you are measured against. This section adds the context that does not belong on a one-page printout.
The body-fat table is age-normed, which means the ceiling printed on your sheet is not the ceiling your colleague is measured against. Across the 4 bands here the men's limit runs from 22% to 26% and the women's from 33% to 36%. Knowing where your own band sits stops you from comparing your result against a number that was never meant to apply to you.
The screen on the sheet is a ratio rather than a weight, so a scale is not the tool you need for it. Bring a tape and know your height in the same unit. The gate of 0.55 translates to a waist below 38.5 inches at 70 inches tall, so measuring at home beforehand tells you whether a tape test is likely rather than leaving it to the day.
