Last reviewed: May 2, 2026
All measurements in inches (US Army standard)
How it works
Calculate your body fat percentage using the official US Army method (AR 600-9). Enter your height, neck, waist, and hip measurements to see if you meet military body composition standards. Includes pass/fail assessment by age group.
How to Use This Calculator
- Measure your neck circumference just below the larynx.
- Measure your waist at navel level (men) or narrowest point (women).
- Women also measure hips at the widest point.
- Enter measurements, height, and age to get your Army body fat percentage.
Example
Inputs: Male, 180 cm, age 28, neck 40 cm, waist 85 cm
Result: ~17.5% body fat (passes Army standard)
What it means: 17.5% body fat is under the maximum allowable for a 28-year-old male soldier (22%) — well within regulation.
Tips
- The Army tape test typically reads 3-5% higher than DEXA for lean individuals.
- Stand naturally — don't suck in or flex — when measuring.
- The regulation is AR 600-9; max body fat varies by age bracket and sex.
- If you fail the tape test but look lean, request a body composition re-evaluation.

Frequently Asked Questions
- How does the Army body fat calculator differ from other methods?
- The US Army method uses circumference measurements at specific body sites rather than skinfold calipers or electronic devices. For men, it measures neck and waist circumference; for women, it adds a hip measurement. While not as precise as DEXA scans or hydrostatic weighing, it provides a standardized and accessible estimation used for military fitness assessments.
- What are the Army body fat percentage limits?
- Maximum allowable body fat percentages vary by age and gender. For men, limits range from 20% (ages 17-20) to 26% (ages 40+). For women, limits range from 30% (ages 17-20) to 36% (ages 40+). Soldiers who exceed the BMI screening threshold are measured using the tape test to determine compliance.
- How accurate is the tape test for body fat?
- The Army tape test has a margin of error of approximately 3-5% compared to laboratory methods like DEXA. It can overestimate body fat in muscular individuals with thick necks and underestimate it in others. Despite its limitations, it remains the standard because it is inexpensive, quick to administer, and reproducible across thousands of testing locations.
