# Army Body Fat Calculator

Calculate body fat using the US Army circumference method (AR 600-9). Compare military fitness standards across US, UK, Australia, and Canada.

## Quick answer

US Army uses waist, neck (and hip for women) measurements to calculate body fat %. Limits: men ≤20–26% (age-dependent); women ≤30–36%. UK Army uses BMI + fitness test, not body fat %. Australia uses waist-to-height ratio. Canada uses BMI. The US method (Hodgdon & Beckett, 1984) is one of the only militaries using circumference-based body fat calculation.
