Army Body Fat Calculator

Circumference body fat alongside the AR 600-9 maximum allowable standard.

This tool applies the same circumference equations and compares the result against the US Army's allowable limit for your age band and sex.

Your details

The formulas use different coefficients for each sex.

Typical range: 17 – 100

Typical range: 100 – 250

Just below the larynx, tape parallel to the floor.

At the narrowest point for women, at navel level for men.

Typical range: 40 – 200

At the widest point of the hips.

Typical range: 50 – 200

Formula and method

Hodgdon–Beckett equations for the percentage, and the AR 600-9 limit table for comparison.

Formula used

Hodgdon-Beckett circumference equations with AR 600-9 limits

Assumptions and limits

  • The limits rise with age: from 20% for men under 21 to 26% at 40 and over.
  • This is not an official assessment and does not replace measurement by authorised personnel.
