Calculate the current U.S. Army waist-to-height ratio (WHtR) from height and waist circumference. The page keeps its established Army calculator URL, but the calculation now follows Army Directive 2026-13, which rescinded the former one-site body-fat equation and made WHtR the sole Army body composition assessment.
How to measure and interpret the result
Enter height in inches and waist circumference measured at the navel. The two measurements must use the same unit for a ratio, but official Army guidance specifies inches. Measurement technique can change the result near 0.550, which is why current policy requires a separate same-day confirmation team after an initial result that does not meet the standard.
The calculator reports the truncated ratio, status, and distance from 0.550. It does not estimate body-fat percentage because the Army has rescinded the previous tape-test body-fat methods.
Examples
70 in height and 36 in waist
36 ÷ 70 = 0.514285... The recorded three-decimal value is 0.514, which is below 0.550 and therefore meets the current standard.
70 in height and 38.5 in waist
38.5 ÷ 70 = 0.550 exactly. The recorded value is 0.550, which does not meet the standard because the policy requires a value less than 0.550.
A value that would round upward
38.49 ÷ 70 = 0.549857... Army policy truncates this to 0.549 rather than rounding it to 0.550, so the recorded value meets the standard.
Formula
Use inches for both official Army measurements:
WHtR = waist circumference at the navel ÷ height
The Army records the result to three decimal places by truncating extra digits, not by rounding. The standard is strictly less than 0.550.
0.549 meets the standard
0.550 does not meet the standard
Policy limits
All Soldiers are screened at least twice per calendar year under the current Army guidance. Pregnancy and postpartum exemptions remain, and other medical or administrative steps depend on official policy and command action. This calculator does not determine an exemption, flag, enrollment, or personnel decision.
