U.S. Space Force
Adopts Air Force / DoD standards (DAFMAN 36-2905)
Data updated: 2026-08-19 (verified vs primary service regulations)
How the screen works
Guardians are measured via Waist-to-Height Ratio (0.55 pass/fail), assessed separately from the fitness test. The body-fat ceiling aligns with the DoD corridor (26% men / 36% women).
| 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 |
Maximum allowable body-fat % (age / sex)
| Age group | Men (max %) | Women (max %) |
|---|---|---|
| All ages | 26% | 36% |
Reading the age-normed ladder
The table above is a ladder rather than a single number, and the width of that ladder is worth knowing before you compare yourself against a colleague. Across the 1 band listed for Space Force, the men's ceiling spans 0 percentage points and the women's spans 0. Because one band covers every age group here, age does not change the allowance for this service — the same figure applies to the youngest and oldest personnel alike.
The Waist-to-Height Ratio gate here sits exactly on the DoD baseline of 0.55, so this service applies the joint standard without tightening or relaxing it. A WHtR is waist divided by height, so the arithmetic has a concrete consequence: at 70 inches tall, the DoD baseline of 0.55 tolerates a waist of up to 38.5 inches while the gate applied here tolerates 38.5 inches.
DoD Instruction 1308.03 also sets an outer corridor: no branch may be stricter than 18% (men) / 26% (women), and none may be looser than 26% (men) / 36% (women). For Space Force the tightest men's band is 26% and the most permissive is 26%, with women's bands running from 36% to 36%. Every band here sits inside the corridor rather than pressed against its limits. The most permissive band reaches the loosest end of the corridor, so older personnel are held to the joint ceiling rather than a service-specific one.
