Army body fat calculator: will you pass the 2026 ABCP waist-to-height standard?
Updated 13 October 2026; standard effective 7 July 2026
Since 7 July 2026 the Army checks every Soldier, whatever their age or sex, with one number: waist divided by height, cut to three decimals without rounding. Under 0.550 passes, so at 5'10" a waist up to 38 inches passes, and at 5'6" up to 36.
How to measure
- Dress like the Army measures you: socks, no shoes, PT trunks and a T-shirt. Gather the shirt up and tuck it into the collar (women may tuck it into the bottom band of a bra instead), or take it off, so your stomach is bare. No compression shorts or shapewear.
- Waist: stand straight with your arms hanging naturally. Wrap a non-stretch tape (fiberglass is best; not cloth) around your bare stomach at the navel, level with the floor all the way around, touching the skin without pressing in. Measure three times, round each reading down to the half inch, and enter the average of the three.
- Height: in socks, stand straight on a flat floor with your head level and eyes forward. Measure from the floor to the top of your head, to the nearest half inch.
- Enter both numbers. The calculator follows the Army's rules: it rounds the waist down to the half inch and cuts the ratio to three decimals without rounding, so 0.549 passes and 0.550 doesn't.
Maximum waist for every height
The largest waist that passes at each height, on the Army's half-inch grid.
| Height | Height (in) | Max waist (in) |
|---|---|---|
| 4'10" | 58 | 31.5 |
| 4'11" | 59 | 32 |
| 5'0" | 60 | 32.5 |
| 5'1" | 61 | 33.5 |
| 5'2" | 62 | 34 |
| 5'3" | 63 | 34.5 |
| 5'4" | 64 | 35 |
| 5'5" | 65 | 35.5 |
| 5'6" | 66 | 36 |
| 5'7" | 67 | 36.5 |
| 5'8" | 68 | 37 |
| 5'9" | 69 | 37.5 |
| 5'10" | 70 | 38 |
| 5'11" | 71 | 39 |
| 6'0" | 72 | 39.5 |
| 6'1" | 73 | 40 |
| 6'2" | 74 | 40.5 |
| 6'3" | 75 | 41 |
| 6'4" | 76 | 41.5 |
| 6'5" | 77 | 42 |
| 6'6" | 78 | 42.5 |
| 6'7" | 79 | 43 |
| 6'8" | 80 | 43.5 |
Two worked examples
- Passes: 5'9" (69 in), 36-inch waist. 36 ÷ 69 = 0.521.
- On the line: 5'10" (70 in), 38.5-inch waist. 38.5 ÷ 70 = 0.550, which fails. At 38 inches it would pass (0.542).
Common questions
Is there a 2025 version of this calculator?
The 2025 rules, the tape test and the height and weight tables, were retired on 7 July 2026. This calculator uses the current standard.
Does the Army still use the tape test?
No. The tape test ended on 7 July 2026, and a tape test or DEXA scan can't be used to challenge a waist-to-height result.
Is there still an Army height and weight chart?
No. Waist-to-height replaced the height and weight tables on 7 July 2026. The table on this page shows the largest passing waist at each height instead.
What's the maximum waist for my height?
At 5'10" it's 38 inches, and at 5'6" it's 36. The table on this page covers 4'10" to 6'8", and the calculator handles half inches.
Is body fat part of the AFT, and can a high score exempt me?
No to both. The AFT is the fitness test and the waist-to-height screen is separate, and Army Directive 2026-13 ended the exemption for scores of 465 and up, so no AFT score exempts you.
What happens if I fail?
A different team measures you again the same day before anything happens, and the result goes on DA Form 5500. Units can start separation paperwork, but no one is separated until the Army finishes a 180-day review of the new standard.
Not in the Army? Other military branches
This calculator uses the Army standard. The Space Force uses the same 0.55 line (SPFMAN 36-2905). The Marine Corps line is stricter, at 0.52 (Marine Corps release). The Air Force, Navy and Coast Guard each add their own scoring or body fat steps, so check your branch's current rules.

This calculator checks the Army ratio; it doesn't estimate body fat percentage. It gives an estimate to help you train. It isn't an official Army measurement; only the measurement your unit takes counts. Standards checked October 2026.
