Waist-to-Height Ratio (WHtR) Gate
The 2026 Department of Defense replaced height-and-weight tables with this single screen across the joint force.
The 2026 Department of Defense primary screen: waist ÷ height. Under 0.55 clears the joint-force screen; the Marine Corps sets a tighter 0.52.

About this calculator
Waist-to-height ratio (WHtR) is a single-number estimate of abdominal fat and the health risk that comes with it. You divide waist circumference by height, both in the same units.
The formula
WHtR = waist ÷ height. A value under 0.50 is generally associated with lower cardiometabolic risk; the 2026 U.S. DoD screen uses 0.55 and the Marine Corps 0.52.
Frequently asked questions
Q: What WHtR clears military screens?
A: Below 0.55 passes the DoD primary screen; below 0.52 also clears the tighter Marine Corps line, with no tape test required.
Q: Why waist instead of BMI?
A: Waist captures central fat, which tracks heart and metabolic risk better than weight-for-height alone.
Q: Do cutoffs differ by sex?
A: The ratio thresholds are close for men and women; the 0.52 and 0.55 lines apply across the joint force.
How to read the result
The ratio is deliberately blunt, which is what makes it usable as a first screen. It needs no scale, no equipment beyond a tape, and no interpretation of body shape, so two people measuring the same waist at the same height reach the same conclusion. That simplicity is why the joint force adopted it in January 2026 in place of height-and-weight tables, which had the awkward property of penalising muscular people while passing others who carried their weight centrally.
The measurement is where most disagreements happen. The tape goes around the bare waist at the level of the navel, parallel to the floor, snug against the skin without compressing it, and the reading is taken at the end of a normal exhale rather than a held breath. Repeating the measurement and averaging removes most of the variation. When the number lands close to the line, that difference in technique is the difference between passing the screen and being sent to a tape test, so measure the same way every time.
Military gate comparison (2026)
See your ratio against every branch’s WHtR screen at once — the joint-force 0.55 line, the Marine Corps 0.52 line, and the first-responder no-gate note.
Your measurements
U.S. customary units. Measure the waist at the navel with a flexible tape, relaxed, after a normal exhale.

| Police / LE | — | 0.486 | NO WHtR GATE |
A PASS clears the initial WHtR screen. At or above the gate, the service runs a secondary body-fat evaluation (DoD Instruction 1308.03 corridor: 18–26% men / 26–36% women depending on branch and age). Estimates are educational — confirm with your command.
