Coast Guard WHtR Standard (2026)
COMDTINST M1020.8 — Body Composition & Physical Fitness — Accession screen uses BMI 19.
The Coast Guard gate
| 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 |
How Coast Guard applies the screen
Accession screen uses BMI 19.0–27.5; the primary in-service screen is abdominal circumference (Men ≤ 39 in, Women ≤ 35.5 in). Body-fat % applies if needed. The Coast Guard is aligning toward the DoD WHtR < 0.55 screen.
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 Coast Guard gate of 0.55 means a waist below 38.5 inches, and at 64 inches tall it means a waist below 35.2 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 matches the DoD baseline of 0.55 exactly, so the joint-force standard applies here without local tightening. 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.

Your measurements
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 |
|---|---|---|---|
| Coast Guard | < 0.55 | 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 0.55, the service runs a body-fat evaluation. Maximum allowable body fat for U.S. Coast Guard:
| Age | Men (max %) | Women (max %) |
|---|---|---|
| Under 30 | 22% | 32% |
| Under 40 | 24% | 34% |
| 40+ | 26% | 36% |
