In 2026, the Army replaced the old height/weight tables and tape test with a single waist-to-height-ratio standard (Army Directive 2026-13). Use the calculator below to check where you stand — then read on for how the measurement works and what the result means.

Check the 2026 Army waist-to-height-ratio standard. Measure your waist at the navel, relaxed — then enter it below with your height.

Standard: Army Directive 2026-13 — waist-to-height ratio must be under 0.550 to pass. This is a universal standard (no age or sex bands) and replaces the old height/weight tables and tape test.

BODY-COMPOSITION FAQ
What is the Army body-composition standard in 2026?
Under Army Directive 2026-13, the standard is a waist-to-height ratio under 0.550. Divide your waist circumference (measured at the navel) by your height in the same units. The standard is universal — it does not vary by age or sex.
How do I measure my waist correctly?
Measure at the navel (belly button), with the tape horizontal and snug but not compressing the skin. Stand relaxed, breathe normally, and measure at the end of a normal exhale. Take the measurement in the morning before eating for the most consistent reading.
What happens if I fail body composition?
Failing the body-composition standard can flag you for the Army Body Composition Program and affect your record. Talk to your chain of command and unit medical staff about the current process — this page is a study aid, not official guidance.
Does the AFT still exempt me from body composition?
No. The old policy that exempted high AFT scorers from the tape test was rescinded with the 2026 changes. Body composition is now assessed by the waist-to-height ratio for everyone.
Inches or centimeters — does it matter?
No. The ratio is unitless, so inches, centimeters, or any consistent unit give the same result. Just use the same unit for waist and height.
How the 2026 standard works
The formula is simple: waist circumference ÷ height, both in the same units. The result must be under 0.550 to pass. Unlike the old system, there are no separate tables by age or sex — one number applies to every soldier.
Worked example: a soldier with a 34-inch waist and a 70-inch height has a ratio of 34 ÷ 70 = 0.486 — a pass, with room to spare. A 40-inch waist at the same height gives 0.571 — a fail.
How to measure correctly
- Measure at the navel (belly button), tape horizontal
- Tape snug against skin — not compressing, not loose
- Stand relaxed; measure at the end of a normal exhale
- Measure in the morning before eating for consistency
- Use the same unit (inches or cm) for waist and height
What changed from the old system
Before 2026, the Army used height/weight screening tables plus a tape test (neck and waist for men; neck, waist, and hips for women) to estimate body fat. That system is gone. There is also no more AFT-based exemption — scoring high on the fitness test no longer waives body-composition assessment. Everyone is measured against the 0.550 ratio.
