How to perform Army WHtR measurements correctly
This 80-second vertical video covers the measurement team, required clothing and tape, waist placement at the navel, three readings, rounding down, averaging, calculation, and confirmation requirements.
Source footage is a public-domain U.S. Army demonstration published through DVIDS.
Read video transcript
Prepare two trained measurers, a fiberglass tape, and the required uniform. Measure the waist at the navel with the tape level and flat without pressing into the skin. Take three measurements and round each down to the nearest half inch. Divide the average waist by height, keep three decimals, and do not round the ratio. A result of 0.55 or higher requires same-duty-day confirmation by a different team.
Army standard explained
How to calculate Army WHtR
- Record height to the nearest 0.50 inch. Measure the waist at the navel three times, rounding each measurement down to the nearest 0.50 inch.
- Average the three waist measurements to three decimal places, divide that average by height, then disregard digits after the third decimal place without rounding the WHtR.
- Compare the reported ratio with less than 0.55.
What happens next?
A second WHtR measurement by a different team on the same duty day is required before administrative action. If the confirmation measurement is still 0.55 or higher, enrollment in ABCP and flagging apply under the public FAQ.
