U.S. Army — Body-Fat Limit for 17–20 men
Data updated: 2026-08-19 (verified vs primary service regulations)
Maximum allowable body-fat percentage
| Population | Max body-fat % | Authority |
|---|---|---|
| Army — 17–20 men | 20% | AR 600-9 — Army Body Composition Program |
The 17–20 male maximum is part of the Army body-composition program (AR 600-9 — Army Body Composition Program). The initial screen is a Waist-to-Height Ratio below 0.55; at or above that line a secondary body-fat evaluation applies.
ACFT 540+ (80 pts/event) exempts the tape test. Accession (enlistment) standards are ~4 points more lenient for men.

Where the 17–20 band sits in the Army table
The Army standard is age-normed for men across 4 bands, so the allowance you receive depends on which age range you fall into rather than on one fleet-wide number. For 17–20 men the ceiling is 20%. That is the tightest band in the table: 17–20 is the most restrictive point for men, and every older band allows more.
The practical consequence is that a reading which fails for one service member can pass for another at a different age, which is why the regulation is applied against the band matching the individual rather than against a single fixed target. If your measured value sits above the ceiling for 17–20 men, the next step is the failure process your service defines rather than a re-test against the same standard.
How Army measures body composition
The Army uses a one-site abdominal circumference tape test at the navel (adopted 2023) scored against an age/sex body-fat table. In 2026 the Army is transitioning toward the DoD WHtR < 0.55 screen (Army Directive 2026-13); confirm the current implementation with your command. Soldiers who score 540+ on the ACFT (minimum 80 points per event) are exempt from the circumference assessment.
The method matters as much as the number, because different techniques produce different readings on the same person. A circumference or tape assessment depends on where the tape is placed and how it is tensioned, while an impedance reading depends on hydration and recent exercise. That is why a regulation names an approved method and a measurement protocol, and why a value obtained by another route is an estimate you can plan with rather than a substitute for the official assessment.
The publicly circulated one-site regression (weight + abdominal circumference) is an estimate; the official ABCP calculator also uses height and age. Use it for planning only.

The full verified table for this service, so you can compare your band with the others at a glance. Men and women are tracked separately because the physiological ranges differ, and every figure comes from the same regulation cited above.
| Age band | Men (max %) | Women (max %) |
|---|---|---|
| 17–20 — your band | 20 | 30 |
| 21–27 | 22 | 32 |
| 28–39 | 24 | 34 |
| 40+ | 26 | 36 |
