The 2026 Shift: Waist-to-Height Ratio (WHtR)
Effective January 1, 2026, the Department of Defense replaced the traditional height-and-weight tables as the first-line body-composition screen with a single waist-to-height ratio measurement. You pass the initial screen if your WHtR is below 0.55 (the Marine Corps uses a tighter ≤ 0.52). If your WHtR meets or exceeds the threshold, you move to a secondary evaluation — the circumference-based tape test — which estimates body-fat percentage. The tape test did not disappear; it now functions as a follow-up rather than the first-line tool.
How to calculate WHtR
Divide your waist circumference (measured at the navel) by your height, in the same units. Example: at 70 inches tall, 70 × 0.55 = 38.5 — so your waist needs to be under about 38.5 inches to clear the DoD-wide screen. Try it with our free calculator above.
WHtR Screen by Branch (2026)
| Branch | WHtR Pass Threshold | WHtR Is First-Line? | Governing Instruction |
|---|---|---|---|
| Army | < 0.55 | Yes | Army Directive 2026-13 / AR 600-9 |
| Navy | < 0.55 | Follow-up | MyNavyHR Guide-4 (Body Composition Assessment) |
| Air Force | < 0.55 | Follow-up | DoDI 1308.03 / Air Force Physical Requirements |
| Marine Corps | < 0.52 | Yes | MARADMIN 066/26 / MCO 6110.3 |
| Coast Guard | < 0.55 | Follow-up | Coast Guard Body Composition Standards Program |
Maximum Body-Fat Ceilings by Age & Sex
Within the DoD Instruction 1308.03 corridor (no branch more restrictive than 18% male / 26% female, none more lenient than 26% male / 36% female), each service calibrates its own age-based limits. Younger service members face the tightest requirements.

Fitness Exemptions & Allowances
The military recognizes that the tape test is imperfect for muscular service members. The Marine Corps grants a +1% body-fat allowance to Marines scoring 250 or higher on both the Physical Fitness Test and Combat Fitness Test, and raises the ceiling to 26% male / 36% female for those scoring 285 or higher on both. The Army exempts soldiers scoring 540+ on the Army Combat Fitness Test (with at least 80 points per event) from the tape test entirely. Commanders also retain limited waiver discretion.
How the Tape Test Works (Secondary Follow-Up)
When someone exceeds the WHtR threshold, a trained technician measures circumference at specific sites with a standardized tape; those measurements feed a formula that estimates body-fat percentage. For men, the neck and waist are measured; for women, the neck, waist, and hips. The result is compared against the branch ceiling above. Our calculator reproduces this Navy-circumference estimate so you can see where you would land.
