Army Body Fat & BMI Calculator
Check your current Army waist-to-height ratio (the Army’s sole body composition standard since July 2026), your BMI, and — for reference — the legacy circumference body-fat estimate.

The current Army body composition standard: waist-to-height ratio
Since Army Directive 2026-13 took effect on July 7, 2026, the Army’s sole body composition standard is the waist-to-height ratio (WHtR). Your waist, measured at the navel after a normal exhale, divided by your height — both in inches — must come out under 0.550. The directive rescinded the old height-and-weight screening tables, the one-site tape test, and every supplemental body-fat method, including DXA, InBody, and Bod Pod scans. There is no age adjustment and no sex adjustment: one line applies to every Soldier. For the full breakdown of the directive and how it phased in, see the AFT standards page on AFTScore.
Practically, that means your allowed waist scales directly with your height — every extra inch of height adds about 0.55 inches of allowed waist. There’s also no fitness-test exemption anymore: a high Army Fitness Test score does not exempt a Soldier from the WHtR check. If you haven’t run your current AFT numbers yet, the AFT calculator covers all five events.
Timeline of the change
- Through July 2026 — Army used a one-site, navel-only circumference tape test converted to an estimated body-fat percentage, compared against age- and sex-based limits.
- July 1, 2026 — Army Directive 2026-13 signed, replacing all body-fat methods with WHtR.
- July 7, 2026 — WHtR standard announced Army-wide and made effective.
- September 29, 2026 — every Soldier required to have a WHtR result recorded.
What about BMI?
Body Mass Index (weight in kilograms divided by height in meters squared) is a general civilian wellness measure, not an official Army standard — the Army has never used BMI to determine body composition compliance. It’s included here because it’s a quick, widely understood reference point for overall weight status, useful alongside WHtR rather than instead of it. BMI doesn’t distinguish muscle mass from fat, which is why a well-conditioned, muscular Soldier can show a “high” BMI while comfortably passing WHtR.
| BMI range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
The legacy tape test (rescinded)
Before July 2026, the Army estimated body fat from a circumference formula: waist and neck for men, waist, hip, and neck for women, converted to a percentage and checked against limits that varied by age band and sex — roughly 20–26% for men and 30–36% for women, tightening for younger age groups. That method, along with the height/weight screening tables it worked alongside, is no longer in effect. It’s kept in this calculator purely so Soldiers can compare an old score against the current WHtR result — not as something you’ll be assessed against today.
Frequently asked questions
Is the Army tape test still used?
No. Army Directive 2026-13 rescinded the circumference-based tape test on July 7, 2026. Waist-to-height ratio is now the only Army body composition standard.
What WHtR do I need to pass?
Under 0.550 — your waist in inches divided by your height in inches. There’s no separate table by age or sex.
Does a good AFT score exempt me from a body composition check?
No. The body-fat exemption tied to a high AFT/ACFT score was rescinded along with the old assessment methods. WHtR is checked independently of your fitness test score.
Does the Army use BMI?
No, not as an official standard. BMI is shown here only as a general wellness reference alongside the current WHtR standard.
