Army Body Composition Calculator 2026
Calculate the current U.S. Army waist-to-height ratio (WHtR), apply the official three-decimal truncation rule and compare the recorded result with the 0.55 standard.
Current policy, not the retired tape test: Army Directive 2026-13 made WHtR the sole Army body-composition assessment. This tool does not estimate body-fat percentage and cannot replace an official measurement or DA Form 5500.
Formula and official recording rule
WHtR = waist circumference at the navel ÷ height
Use the same unit for both measurements. The Army records the ratio to three decimal places without rounding: digits after the third decimal are discarded. A recorded value below 0.550 passes the body-composition screening standard; 0.550 or higher does not.
This means 0.549 is a passing recorded value and 0.550 is a failing value. The calculator shows both the full arithmetic ratio and the official truncated value so the two are not confused.
Checked examples
| Height and waist | Raw ratio | Recorded | Result |
|---|---|---|---|
| 72 in height, 38.4 in waist | 0.533333… | 0.533 | Meets standard |
| 70 in height, 38.49 in waist | 0.549857… | 0.549 | Meets standard |
| 70 in height, 38.5 in waist | 0.550000 | 0.550 | Does not meet standard |
| 180 cm height, 98 cm waist | 0.544444… | 0.544 | Meets standard |
How to use the result
- Measure height and waist using the current Army procedure. The official waist site is the navel.
- Enter both measurements in the same unit. Feet and inches are combined automatically.
- Read the recorded WHtR, which is truncated rather than rounded.
- If the initial official measurement does not meet the standard, current policy requires confirmation on the same duty day by a different team before administrative action.
An Army Fitness Test score does not exempt a Soldier from the WHtR standard under the July 2026 policy. Pregnancy and postpartum medical exemptions remain subject to official policy and documentation.
Limits and sources
- This is an educational arithmetic check, not an official Army assessment, medical evaluation, diagnosis, eligibility decision or personnel record.
- It does not estimate body-fat percentage. Earlier height/weight tables, circumference body-fat tape tests and supplemental body-fat assessments were rescinded by the 2026 directive.
- Tape position, tension, posture and transcription can affect the result. Near the threshold, rely on the official measurement team and current forms.
- The 2026 directive includes an Army review period and later guidance may change implementation. Verify the active source before relying on this tool.

Questions
Is this an Army body-fat percentage calculator?
No. Since July 2026, the Army uses waist-to-height ratio as its sole authorized body-composition assessment. This calculator intentionally does not output the retired tape-test body-fat percentage.
Why is 0.549 passing but 0.550 failing?
The standard is less than 0.55. The official recorded ratio keeps three decimals without rounding, so 0.549 is below the line and 0.550 is not.
Do centimetres change the result?
No. Dividing centimetres by centimetres gives the same ratio as inches divided by inches. The metric option is a convenience; the official Army procedure specifies inches.
