Army body fat calculator
The Army now scores body composition on your waist-to-height ratio, pass if it is under 0.55. Enter your height and waist to check it, plus a body-fat estimate from the previous tape-test method.
The Army body fat standard, as of July 2026, is a waist-to-height ratio under 0.55: your waist measured at the navel, divided by your height, must be less than 55 percent. It is the same pass line for every soldier, with no age or gender brackets, and it replaced the old tape-test body-fat percentage.
Current Army standard (from 7 July 2026): waist-to-height ratio under 0.55, no age or gender adjustment. The body-fat percentage uses the previous one-site tape-test formula, which the Army rescinded in July 2026, shown here for reference only. Source: Army body composition standard (AR 600-9).

How the Army measures body composition
In July 2026 the Army moved to a single measure: your waist-to-height ratio. Divide your waist (measured at the navel) by your height in the same unit, and you pass if the result is below 0.55. The same line applies to everyone, so there are no age brackets or gender adjustments, and no body-fat percentage in the official standard.
Before that, the Army used a one-site abdominal tape test to estimate body-fat percentage, checked against a maximum for your age. That method was rescinded, so the body-fat figure here is an estimate from the old formula, useful for context, not an official result.
