One waist and one height against the Army, Air Force, Navy and Marine Corps rules side by side — each service’s own line and its own rounding, exactly as the rule reads.
0.5000
36 in ÷ 72 in · each service applies its own rounding, and each row says the largest waist that meets its line at your height:

The largest waist that still earns each row of the chart at your height, with the ratio truncated to 2 decimals as AFMAN 36-2905 says. Your row is marked.
Navy step 2: Not modeled — the body-fat calculation that follows a ratio over 0.5499 isn’t computed here (checked October 6, 2026).
Marine Corps body-fat allowances: Not modeled — the allowances for 285+ and 250+ on both the PFT and CFT are stated in MARADMIN 066/26, not computed here (checked October 6, 2026).
Space Force and Coast Guard: Not modeled — their own body composition programs aren’t covered by this tool (checked October 6, 2026).
Measure where your service does — the services don’t use the same spot. The Army, Navy and Marine Corps measure at the navel; the Air Force measures midway between the lowest rib and the top of the hip bone. The number of measurements differs too.
| Army | Where: at the navel (belly button), tape parallel to the floor (EXORD 182-26 Annex A). How: Waist measured three times, each recorded down to the nearest half inch (a fourth if one differs by more than an inch); height to the nearest half inch. Ratio: truncated to 3 decimals (0.549888 → 0.549; 0.550 does not meet). |
|---|---|
| Air Force | Where: midway between the lowest rib and the top of the hip bone (iliac crest), on bare skin, at the end of a normal breath out (AFMAN 36-2905, 3.15.4.5). How: Waist measured three times, each rounded down to the nearest half inch (a fourth if one differs by more than an inch), the three closest averaged and rounded down to the half inch; height to the nearest half inch. Ratio: truncated to 2 decimals for points. |
| Navy | Where: at the belly button (umbilicus), tape parallel to the deck, after a normal breath out (PRP Guide-4). How: Waist measured two times, each rounded down to the nearest half inch (if they differ by more than an inch, a third, and the two closest averaged); height rounded up to the nearest half inch. Ratio: rounded down to the fourth decimal place (0.5499). |
| Marine Corps | Where: at the navel, tape parallel to the deck (MARADMIN 066/26). How: Waist measured twice, the lower kept, rounded down to the nearest half inch; height rounded down to the nearest half inch. Ratio: no rounding stated — the unrounded ratio is compared. |
The Army’s old 465/80 body-fat exemption was rescinded by Army Directive 2026-13; it no longer applies.
