What is calculated
The current Army measure is waist-to-height ratio, not an estimated body-fat percentage. The final recorded result must be below 0.550.
Official recording sequence
Height is recorded to the nearest half inch. Each waist reading is rounded down to the next half inch, the three selected readings are averaged, and the final ratio is truncated to three decimals.
Important limitation
This independent planning tool cannot replace the measurement team, confirmation assessment, DA Form 5500, or current Army policy.

Review method
The team compared the implemented sequence with DA Form 5500 and the July 2026 implementing guidance, then ran boundary, unit, outlier, and official-table fixtures.
Known limitations
- This is an independent planning calculation, not an official personnel decision.
- The current DA Form 5500, implementing guidance, and Army policy control.
- The maximum-waist reference is limited to recorded heights from 48.0 to 83.5 inches.

Direct answer: how the current Army calculation works
The formula is:
WHtR = average recorded waist circumference ÷ recorded height
Use inches for the official worksheet. The ratio itself has no unit, so mathematically it is unchanged when both values use the same unit. However, a metric planning input must still be converted before applying the Army's half-inch recording rules.
The official sequence matters:
- Measure height without shoes and record it to the nearest 0.5 inch.
- Measure the waist at the navel three times.
- Round each waist measurement down to the nearest 0.5 inch.
- Average the three recorded waist values to three decimal places.
- Divide average waist by recorded height.
- Discard every digit after the third decimal; do not round the ratio.
- Compare the recorded value with 0.550.
0.549 meets the standard. 0.550 does not.
Worked Army WHtR example
Suppose recorded height is 70.0 inches and the three raw waist readings are 38.49, 38.62, and 38.50 inches.
| Step | Calculation | Result |
|---|---|---|
| Round each waist reading down to 0.5 inch | 38.49 → 38.0; 38.62 → 38.5; 38.50 → 38.5 | 38.0, 38.5, 38.5 |
| Average the recorded readings | (38.0 + 38.5 + 38.5) ÷ 3 | 38.333 inches |
| Calculate raw WHtR | 38.333 ÷ 70.0 | 0.547614… |
| Record three decimals without rounding | discard digits after 0.547 | 0.547 |
| Compare with the standard | 0.547 < 0.550 | Meets the standard |
This is a planning example. An official result requires the prescribed equipment, posture, trained personnel, and recording process.
The cutoff mistake that can reverse a result
Do not round a raw ratio in the usual way. DA Form 5500 instructs users to disregard digits after the third decimal. Its own example records 0.549888 as 0.549, which meets the standard. By contrast, a recorded 0.550 does not meet the standard.
Also do not interpret “0.55 or less” as passing. The official threshold is less than—but not equal to—0.55.
What changed in July 2026?
The new policy made WHtR the Army's sole body-composition assessment. The former height-and-weight tables, circumference-based body-fat calculations, and supplemental methods used to challenge a result are no longer authorized for current ABCP compliance.
The standard is not adjusted by age or sex. Weight, neck circumference, and hip circumference are not inputs to the current compliance calculation. DA Form 5500 still records administrative information such as age and sex, but those entries do not change the 0.550 threshold.

How to measure for a planning check
For an official assessment, trained personnel measure the Soldier. For a private planning check:
- Stand naturally with arms at the sides.
- Find the navel, not the narrowest part of the waist and not the trouser waistband.
- Keep a non-stretch tape horizontal and in contact with the body without compressing soft tissue.
- Take three readings and apply the recording rules only after each measurement.
- Measure height without shoes on a flat surface.
See How to Measure Waist for the Army WHtR Test for the complete procedure, equipment guidance, and unusual-landmark cases.
Maximum waist is height-specific
The ratio creates a different maximum recorded waist for each half-inch of height. Do not simply display height × 0.55 as “the maximum allowed.” Equality fails, and the Army records waist in half-inch steps. For example, at 70 inches, 38.5 ÷ 70 = 0.550, so 38.5 inches does not meet the standard; the official table lists 38.0 inches as the maximum permitted recorded waist.
Use the Army Maximum Waist by Height Chart to check the official 48–83.5-inch reference range.
What happens after a result at or above 0.550?
An initial noncompliant measurement is not the last step. Current Army guidance requires a confirmation measurement on the same duty day by a different team before action. If the confirmation also does not meet the standard, the Soldier is enrolled in the Army Body Composition Program and flagged under current policy.
The Army FAQ states that the flag is non-transferable, so the Soldier cannot PCS, while remaining eligible to deploy. Current pregnancy and postpartum medical exemptions remain. The Army also states that no separation action for WHtR failure will occur during its initial 180-day assessment until additional guidance is issued. Because this is time-sensitive, verify the latest official policy rather than relying on a cached summary.

AFT score and WHtR are separate requirements
A strong Army Fitness Test result does not exempt a Soldier from the body-composition standard. Army Directive 2026-13 rescinded the earlier AFT-based exemption. Use the AFT Calculator to estimate fitness-test performance, but interpret it separately from WHtR.
WHtR is not body-fat percentage
WHtR is a ratio of waist circumference to height. It does not report the percentage of body mass that is fat, and it should not be converted into a body-fat percentage. If your goal is general body-composition tracking rather than Army compliance, use the Body Fat Calculator. For the separate circumference equations commonly associated with the U.S. Navy method, use the Navy Body Fat Calculator.
The current Army calculation is explained alongside the superseded tape methods in Army Tape Test vs WHtR.
Frequently asked questions
What is the Army body-fat standard in 2026?
The current ABCP standard is not a body-fat percentage. It is a recorded waist-to-height ratio below 0.550.
Does 0.550 pass the Army WHtR test?
No. The standard is less than, but not equal to, 0.55. A recorded value of 0.549 meets the standard; 0.550 does not.
Does the Army still use height-and-weight tables?
No. The Army says WHtR replaced the former height-and-weight screening tables.
Do age or sex change the Army WHtR cutoff?
No. The current 0.550 cutoff is universal for Soldiers covered by the policy. Age and sex do not change the calculation.
Does an AFT score exempt a Soldier from WHtR?
No. The current Army directive rescinded the performance-based AFT exemption.
How often are Soldiers screened?
The Army states that all Soldiers are screened at least twice per calendar year. Commanders may direct additional assessments under the circumstances described in current policy.
Can I challenge a WHtR result with the old tape test or another body-fat method?
No. The Army states that previous body-fat assessment methods and supplemental challenge methods are not authorized for current ABCP compliance. An initial noncompliant WHtR result receives a confirmation measurement by a different team.
Can I use centimeters?
The mathematical ratio is the same when waist and height use the same unit. The official Army procedure records inches and applies half-inch rules, so a metric planning result should be converted before reproducing the official worksheet sequence.
