Marine Corps WHtR Standard (2026)
MCO 6110.3 / MARADMIN 066/26 — Effective January 1, 2026, the Marine Corps replaced height-and-weight tables with a Waist-to-Height Ratio screen set tighter than the DoD baseline at 0.

| Initial screen | Threshold | Result |

| Waist-to-Height Ratio (WHtR) | must be < 0.52 | Below passes with no tape test; at or above → secondary body-fat evaluation |
How Marine Corps applies the screen
Effective January 1, 2026, the Marine Corps replaced height-and-weight tables with a Waist-to-Height Ratio screen set tighter than the DoD baseline at 0.52 (waist measured at the navel ÷ height). Exceeding 0.52 triggers a body-fat evaluation (multi-site tape or BIA). Body-fat standards remain sex- and age-normed.
The arithmetic behind the gate is worth doing once so the number stops being abstract. A Waist-to-Height Ratio is your waist measurement divided by your height, both in the same unit, so a fixed ratio corresponds to a different waist for every height. At 70 inches tall the Marine Corps gate of 0.52 means a waist below 36.4 inches, and at 64 inches tall it means a waist below 33.3 inches. That is why a waist figure alone says nothing about whether you pass: the height it is being measured against is half of the calculation.
This gate is 0.03 tighter than the DoD baseline of 0.55, which is the difference between a screen that passes and one that sends a member onward to a tape test. Measurement technique is the other half of the result. Measure the bare waist at the navel, keep the tape parallel to the floor, do not compress the skin, and read at the end of a normal exhale rather than a held breath. The same person measured with two different techniques can land on either side of the line.

U.S. customary units. Measure the waist at the navel with a flexible tape, relaxed, after a normal exhale.
Verdict by branch (2026)
| Branch | WHtR gate | Your ratio | Result |
|---|---|---|---|
| Marine Corps | < 0.52 | 0.486 | PASS |
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.
Secondary body-fat evaluation
If your WHtR is at or above 0.52, the service runs a body-fat evaluation. Maximum allowable body fat for U.S. Marine Corps:
| Age | Men (max %) | Women (max %) |
|---|---|---|
| 17–26 | 18% | 26% |
| 27–39 | 19% | 27% |
| 40–45 | 20% | 28% |
| 46+ | 21% | 29% |
