Not Army? WHtR is now a Pentagon-wide standard. Every branch screens body composition with the same ratio — waist ÷ height — but the passing line isn't identical everywhere.

This page explains how the Army's waist-to-height ratio standard works under AR 600-9, following Army Directive 2026-13 — what changed on July 7, 2026, how to measure correctly, and what your target waist should be at your height. It applies the same way whether you're Active Duty, Army National Guard, Army Reserve, a USMA or Senior ROTC cadet, or preparing for MEPS.

What Changed on July 7, 2026

Army Directive 2026-13 rescinded the height-and-weight screening tables, the circumference-based tape test, and every prior supplemental body fat method — including DXA, InBody, and Bod Pod scans. In their place, it established waist-to-height ratio as the Army's sole authorized body composition standard.

CategoryBefore (Rescinded)Now (AD 2026-13)
Screening methodHeight/weight tables (AR 600-9 Table B-1)WHtR only — no separate screening step
Body fat assessmentOne-site tape test converted to an estimated body fat %WHtR itself is the standard — no body fat % is calculated
Age adjustmentFour brackets (17–20, 21–27, 28–39, 40+)None — one 0.550 threshold for every age
Gender adjustmentSeparate, higher limits for female SoldiersNone — same 0.550 threshold for everyone
AFT score exemption465+ AFT score exempted a Soldier from tapingNone — AFT and WHtR are fully independent
Confirmation retestCould occur at a later dateSame duty day, by a different team
ABCP oversight while enrolledMandatory monthly assessmentsCommander determines assessment timing
Forms usedDA Form 5500 (male) / DA Form 5501 (female)DA Form 5500 only — 5501 discontinued

The practical effect: your fitness test score, age, and gender no longer factor into your body composition result at all. Your waist and your height are the only two numbers that matter, applied the same way across the Regular Army, Army National Guard, and Army Reserve.

Target Waist by Height

Because the standard requires a ratio below 0.550, your waist must come in under the figure below, not equal to it. These are independently calculated (height × 0.550), so use them as a quick reference — for your exact ratio and margin, use the calculator above.

HeightWaist Must Be Below
58 in (4'10")31.9 in
60 in (5'0")33.0 in
62 in (5'2")34.1 in
64 in (5'4")35.2 in
66 in (5'6")36.3 in
68 in (5'8")37.4 in
70 in (5'10")38.5 in
72 in (6'0")39.6 in
74 in (6'2")40.7 in
76 in (6'4")41.8 in
78 in (6'6")42.9 in
80 in (6'8")44.0 in

Odd heights (e.g. 5'7", 5'9") fall between these rows — use the calculator above for your exact figure.

The 90-Day Recording Deadline

Every Soldier needs an initial WHtR on record. Army Directive 2026-13 requires a WHtR screening recorded on DA Form 5500 and in the Army Training Information System (ATIS) within 90 days of the directive's publication — landing in early October 2026. Leaders record results in ATIS using the Leader Tool. This is a one-time catch-up; after it, the normal twice-yearly cycle applies.

If your unit hasn't scheduled your initial screening yet, that deadline applies regardless. Checking your number now means you walk into that appointment already knowing where you stand.

How to Measure Your Waist Correctly

WHtR is only as accurate as the measurement behind it. Follow the same steps every time:

  1. Find your navel. The measurement is taken at the navel, not the narrowest point of your waist or your hip bones.
  2. Exhale normally. Don't suck in or push out your stomach — either throws off the result.
  3. Keep the tape level. Wrap it horizontally around your body, parallel to the floor.
  4. Snug, not tight. The tape should sit against your body without compressing the skin.
  5. Measure against skin or a thin shirt. Bulky clothing adds inches that aren't really there.
  6. Measure at a consistent time of day if you're tracking a trend — waist size shifts slightly through the day.

What Happens If Your Ratio Is 0.550 or Higher

  1. Initial measurement at or above 0.550. A confirmation measurement follows, on the same duty day, conducted by a different team.
  2. Confirmation also at or above 0.550. You're enrolled in the Army Body Composition Program (ABCP) and flagged, remaining enrolled until you meet the standard. Under AD 2026-13, your commander determines when you're reassessed — the previous mandatory monthly assessment requirement was rescinded, and you come off ABCP as soon as you meet standard.
The 180-day review, in plain terms: the Army is conducting a 180-day assessment of the WHtR standard. Units may still initiate separation actions against a flagged Soldier, but no Soldier will actually be separated for a WHtR failure until that review is complete and further guidance is issued. That window is time to work on your ratio — not a reason to skip getting measured by the 90-day deadline above.

The target waist figures earlier on this page are planning numbers, not deadline-panic numbers. There's no benefit to closing the gap quickly through extreme methods, and every reason to close it steadily.

Staying Ready Without Shortcuts

If your number is close to the line, the safe path and the effective path are the same one: consistent strength training, adequate protein, regular sleep, and measuring under the same conditions so you can track a real trend. Avoid rapid weight-cutting methods — fasting, dehydration, sweat suits, or any last-minute technique aimed at a single measurement. These don't produce a lasting change in your ratio, and some carry real health risk.

Frequently Asked Questions

Is the tape test still used by the Army?

No. As of July 7, 2026, waist-to-height ratio (WHtR) replaced the one-site tape test as the sole ABCP body composition standard.

Do age or gender affect the WHtR standard?

No. The 0.550 threshold is a single universal standard, with no age bracket and no gender adjustment — a change from every prior version of AR 600-9 body composition policy.

Does a high AFT score still exempt me from assessment?

No. The fitness-test exemption that previously existed was removed by Army Directive 2026-13. Your AFT score and your WHtR result are now assessed completely independently.

Does this apply to National Guard, Reserve, and cadets?

Yes. Army Directive 2026-13 applies the same WHtR standard to the Regular Army, Army National Guard, Army Reserve, USMA cadets, and Senior ROTC cadets.

How precise does my result need to be?

The ratio is recorded to three decimal places and truncated, not rounded: 0.549 passes, 0.550 fails. There's no rounding in your favor at the boundary.

Is this calculator official?

No. This is an independent tool built from published Army directives and the ABCP FAQ. Always confirm your results with your chain of command.
