This page supports the Army WHtR Calculator above and explains how the Army's waist-to-height ratio (WHtR) standard works under AR 600-9, following Army Directive 2026-13. Whether you are an Active Duty Soldier, National Guard member, Army Reserve Soldier, or preparing for MEPS, this guide covers exactly what changed on July 7, 2026, how to measure correctly, and what your target waist should be at your height, before an official assessment catches you unprepared.
Two Assessments a Year
Every Soldier is measured under the WHtR standard twice per calendar year. The better move is the same one it always was: check early, understand where you stand, and show up prepared, not stressed. Use the calculator above any time between official assessments.
What Changed on July 7, 2026
Army Directive 2026-13, signed by the Secretary of the Army on July 1, 2026, and effective July 7, 2026, rescinded the Army's height and weight screening tables, the circumference-based tape test, and every prior supplemental body fat assessment method, including DXA, InBody, and Bod Pod scans. In their place, it established the waist-to-height ratio as the Army's sole authorized body composition assessment. The table below summarizes exactly what was replaced.
| Category | Old (Rescinded) | New (Current) |
|---|---|---|
| Screening Method | Height/weight screening tables (AR 600-9 Table B-1) | Waist-to-height ratio (WHtR) only: no separate screening step |
| Body Fat Assessment | One-site circumference tape test (navel), converted to an estimated body fat % | WHtR itself is the standard: no body fat percentage is calculated |
| Age Adjustment | Four age brackets (17–20, 21–27, 28–39, 40+), each with different limits | None: one universal 0.550 threshold for every age |
| Gender Adjustment | Separate, higher body fat limits for female Soldiers | None: the same 0.550 threshold applies to all Soldiers |
| Fallback / Exemption Options | A fitness test score of 465+ (with 80 pts in every event) exempted a Soldier from taping | None: AFT score and WHtR are fully independent; both must be met on their own |
| Forms Used | DA Form 5500 (male) / DA Form 5501 (female) | DA Form 5500 (recorded in ATIS); DA Form 5501 discontinued |
The practical effect is simple to state but important to internalize: your fitness test score, your age, and your gender no longer factor into your body composition result in any way. Your waist circumference and your height are the only two numbers that matter, and the standard, a ratio below 0.550, is the same for every Soldier in the Regular Army, Army National Guard, and Army Reserve.
Target Waist by Height (Reference Table)
The table below shows the exact waist measurement at which your ratio reaches the 0.550 threshold for every height from 4'10" to 6'8". Because the standard requires a ratio strictly below 0.550, your waist must be below the listed figure, not equal to it. For your precise result, including your exact margin, use the Army WHtR Calculator above.
| Height | Waist Must Be Below |
|---|---|
| 58 in (4'10") | 31.9 in |
| 59 in (4'11") | 32.5 in |
| 60 in (5'0") | 33.0 in |
| 61 in (5'1") | 33.6 in |
| 62 in (5'2") | 34.1 in |
| 63 in (5'3") | 34.7 in |
| 64 in (5'4") | 35.2 in |
| 65 in (5'5") | 35.8 in |
| 66 in (5'6") | 36.3 in |
| 67 in (5'7") | 36.9 in |
| 68 in (5'8") | 37.4 in |
| 69 in (5'9") | 38.0 in |
| 70 in (5'10") | 38.5 in |
| 71 in (5'11") | 39.1 in |
| 72 in (6'0") | 39.6 in |
| 73 in (6'1") | 40.2 in |
| 74 in (6'2") | 40.7 in |
| 75 in (6'3") | 41.3 in |
| 76 in (6'4") | 41.8 in |
| 77 in (6'5") | 42.4 in |
| 78 in (6'6") | 42.9 in |
| 79 in (6'7") | 43.5 in |
| 80 in (6'8") | 44.0 in |
The 90-Day Recording Deadline
Army Directive 2026-13 requires every Soldier to have a WHtR screening recorded on DA Form 5500 and in the Army Training Information System (ATIS) within 90 days of the directive's publication date, July 7, 2026 (approximately October 5, 2026). Leaders record the result in ATIS using the Leader Tool. This is a one-time catch-up requirement to get every Soldier's record current under the new standard. After that, the normal twice-yearly assessment cycle applies. Source: ABCP FAQ (army.mil)
If your unit hasn't scheduled your initial WHtR measurement yet, that deadline is coming regardless. Checking your number now with the calculator above means you'll walk into that appointment already knowing where you stand, rather than finding out for the first time in front of your chain of command.
How to Measure Your Waist Correctly
WHtR is only as accurate as the measurement behind it. A rushed or inconsistent measurement can push a passing result over the line, or vice versa. Follow these steps every time:
- Find your navel. The measurement is taken at the navel (belly button), not at the narrowest point of your waist or the top of your hip bones.
- Exhale normally. Breathe out naturally. Do not suck in your stomach or push it out. Either one will throw off the result.
- Keep the tape level. Wrap the tape horizontally around your body at navel height, parallel to the floor, not angled.
- Snug, not tight. The tape should sit against your body without compressing the skin. If you can see an indentation, it's too tight.
- Measure against skin or a thin t-shirt. Bulky clothing adds inches that aren't really there.
- Measure at a consistent time of day. If you're tracking your number over time, measure under the same conditions each time; waist size shifts a little throughout the day.
What Happens If Your Ratio Is 0.550 or Higher
A single measurement at or above 0.550 is followed by a confirmation measurement, conducted on the same duty day by a different team. If the confirmation also shows 0.550 or higher, the Soldier is enrolled in the Army Body Composition Program (ABCP), flagged, and remains enrolled until they meet the standard. The Army is conducting a 180-day review of the WHtR standard. No Soldier will be separated for a WHtR failure until that review is complete and further guidance is issued. Source: ABCP FAQ (army.mil). Your unit's official measurement is what counts. If you're already enrolled or want the full enrollment walkthrough (what happens while enrolled, how to get removed, and the 180-day review), see the ABCP Calculator.
The target waist figures in the table above are planning numbers, not deadline-panic numbers. There is 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 path: consistent strength training, adequate protein, regular sleep, and measuring under the same conditions so you can actually track your trend. Avoid rapid weight-cutting methods: fasting, dehydration, sweat suits, or any last-minute technique meant to shrink a single measurement. These do not produce a real, lasting change in your ratio, and some carry real health risk.

Frequently Asked Questions (FAQs)
Do age or gender affect the WHtR standard?
No. Under Army Directive 2026-13, the 0.550 threshold is a single universal standard. There is 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. AFT score and WHtR are now assessed completely independently: a strong AFT score gives no credit toward your WHtR result.
Is this calculator valid for National Guard and Army Reserve?
Yes. Army Directive 2026-13 applies the same WHtR standard to the Regular Army, Army National Guard, and Army Reserve.
How precise does my WHtR result need to be?
The ratio is recorded to three decimal places without rounding: a result of 0.549 passes, and 0.550 fails. There is no rounding in your favor at the boundary.
Where do I measure my waist for the WHtR standard?
At the navel (belly button), after a normal exhale, with the tape level and snug but not compressing the skin. See the step-by-step guidance above.
