Air Force Height & Weight Requirements 2026

AFMAN 36-2905 has no maximum-weight-for-height chart. Your height and weight are measured at the PFRA ¶3.15.2, 3.15.3, but body composition is scored with the waist-to-height ratio (WHtR): your waist divided by your height ¶3.1.2.1, 3.15.4.2. One table applies to every age and both sexes ¶3.1, 3.15.4.2.

The ratio shows up in rules that people constantly mix up:

• The scored PFRA component. Up to 20 of 100 points: full points at 0.49 or less, zero at 0.60 or more, and no minimum ¶3.7.1. See the WHtR guide and calculator.
• The .55 line. Not a screen and not an automatic fail. A WHtR above .55 only matters when the PFRA does not meet standards: then you take a Tier 2 Body Fat Assessment ¶3.1.1, 3.1.2.1.1. Pass it and body composition is scored as exempt; fail it and the PFRA is Unsatisfactory ¶3.7.2. The flowchart shows every branch.
• The DoD-wide rule. Military Times (9 September 2026) reports that DoW Instruction 1308.03, effective 31 August 2026, sets a WHtR standard below 0.55 across the services. As of 2 October 2026 we have found no Air Force implementation guidance; watch for it.

The waist is recorded rounded down to the ½ inch ¶3.15.4.5 and the ratio is truncated to two decimals ¶3.15.4.2, so these are the largest recorded waists that still reach each line:

Example: 69 in tall with a 36 in waist is 36 ÷ 69 = 0.5217, recorded as 0.52: 17 of 20 points, under .55 but short of the 0.49 full-points line.

Height and weight are obtained in accordance with DoDI 1308.03 ¶3.15.2, at an approved location run by the FAC or UFAC:

Height

Shoes off, on a calibrated stadiometer or wall-mounted measuring device, head level and looking forward, body straight like the position of attention; recorded to the nearest ½ inch ¶3.15.2.1–3.15.2.3.

Weight

Shoes off, on a calibrated scale, recorded to the nearest pound with two pounds subtracted for clothing ¶3.15.3.

Waist (WHtR)

Non-stretch tape on bare skin, from the right side, at the midpoint between the lowest rib and the top of the hip bone; three readings rounded down to the ½ inch and averaged ¶3.15.4.3–3.15.4.6. Full procedure on the WHtR guide.

Joining is a different process. AFMAN 36-2905 leaves new accessions (Basic Military Training, Officer Training School, the Academy and similar programs) to the fitness programs and standards of their school or program ¶6.1.2, and it sets no height, weight or BMI limits for joining. Those are screened through your recruiter and the military medical accession process, so ask your recruiter for the current standard rather than relying on a number from a website.

Once you reach your first duty station, your first PFRA is due at the next unit PFRA or within two months of arrival ¶6.1.1, and from then on the WHtR rules above apply. For the pipelines, see BMT fitness requirements, OTS and AFROTC.

In a sense. The PFRA waist measurement is a tape test, but it is scored relative to your height: the same 36-inch waist is 0.60 (0 points) at 5 ft 0 in and 0.47 (20 points) at 6 ft 4 in.

The older neck-and-waist style tape survives only as the fallback for a Tier 2 Body Fat Assessment, used when no InBody 770 scale is available: neck and abdomen for men; neck, natural waist and buttocks for women, read against the tables in Attachments 9 and 10 ¶3.1.2.1.2, 3.1.2.1.3. You can estimate that result with the Tier 2 BFA estimator. AFMAN 36-2905 does not apply to the Space Force p. 1; for Guardians, see the Space Force standards.
