Learn how to calculate the new Army height and weight standards with this simple guide. The U.S. Army's updated body composition policy uses the waist-to-height ratio (WHtR) for serving soldiers. Measure your waist at the navel, measure your height, and divide your waist measurement by your height using the same units. The recorded ratio must be below 0.550 to meet the standard. This guide explains the formula, measurement steps, worked examples, and common calculation mistakes. Applicants joining the Army may follow different accession requirements, so check the latest official guidelines to determine which standard applies to you.
