Introduction
The Army Body Fat Calculator helps you find out if you meet the U.S. Army body fat standards set by AR 600-9. The Army uses a tape test to measure body fat for all soldiers. If you go over the weight limit on the scale, this tape test decides if you pass or fail. Our tool supports both the new 2023 single-site tape test, which only measures your belly, and the old multi-site tape test, which measures your neck, waist, and hips. Just pick your test, enter your measurements, and get your result in seconds.
This calculator gives you your estimated body fat percentage, shows the maximum body fat allowed for your age and sex, and tells you if you pass or fail. It also breaks down your fat mass and lean mass so you can see where you stand. Whether you are getting ready for a weigh-in, preparing for basic training, or just want to check your body fat, this tool makes it quick and simple.
How to use our Army Body Fat Calculator
Enter your body measurements below to estimate your body fat percentage and find out if you pass the U.S. Army body fat standard. The calculator gives you your body fat percentage, your Army maximum allowed limit, and a pass or fail result.
Test Mode: Pick "New Tape Test" for the 2023 single-site method or "Old Tape Test" for the legacy multi-site method. The new test only needs your abdomen measurement. The old test needs your neck, waist, and hip (females only).
Sex: Select Male or Female. The Army has different body fat limits for men and women, so this choice affects your maximum allowed percentage.
Unit System: Choose Imperial (pounds and inches) or Metric (kilograms and centimeters). All your measurements will convert automatically when you switch.
Age: Enter your age in years, from 17 to 80. The Army sets different body fat limits for each age group, so your age determines your maximum. If you need to verify your exact age, our Age Calculator can help.
Weight: Enter your current body weight in pounds or kilograms. This is used to calculate your fat mass and lean body mass.
Height: Enter your height in feet and inches or centimeters. Height is part of the body fat formula for both test methods. You can use our Height Calculator if you need to estimate or convert your height.
Abdominal Circumference (New Test): Measure around your belly at the level of your belly button. Keep the tape snug but not tight. Take the reading at the end of a normal breath out.
Neck Circumference (Old Test): Measure around your neck just below the Adam's apple. Keep the tape level and perpendicular to your neck.
Waist Circumference (Old Test): Measure around your waist at the level of your belly button. Take the reading at the end of a normal breath out.
Hip Circumference (Old Test, Females Only): Measure around the widest part of your hips and buttocks. Keep the tape level all the way around.

Army Body Fat Calculator
The U.S. Army requires all soldiers to meet body fat standards set by Army Regulation 600-9 (AR 600-9). If a soldier does not pass the initial height and weight screening, they must take a tape test. This test uses a measuring tape to measure certain parts of the body, and then a formula turns those numbers into a body fat percentage. If that percentage is above the allowed limit for your age and sex, you fail the standard. For a broader look at body fat estimation methods beyond the Army tape test, try our general Body Fat Calculator.
How the Army Tape Test Works
There are two versions of the tape test. The new tape test (2023) is simpler. It only measures one spot: your abdomen at the belly button. It compares that number to your height to estimate body fat. The old tape test measures more spots. For men, it measures the neck and waist. For women, it measures the neck, waist, and hips. Both tests plug those measurements into a math formula to get your body fat percentage. If you want to understand your waist and hip numbers in more detail, our Waist to Hip Ratio Calculator and Waist to Height Ratio Calculator provide additional context.
Army Body Fat Limits
The maximum body fat percentage you are allowed depends on your age and sex. Younger soldiers have stricter limits. Here is a quick summary:
- Ages 17–20: 20% for men, 30% for women
- Ages 21–27: 22% for men, 32% for women
- Ages 28–39: 24% for men, 34% for women
- Ages 40+: 26% for men, 36% for women
Why Body Fat Matters in the Army
The Army tracks body fat to make sure soldiers stay fit and ready for duty. Carrying too much body fat can slow you down, hurt your endurance, and raise your risk of injury. Understanding your overall body composition goes beyond just a body fat percentage — tools like our BMI Calculator, Lean Body Weight Calculator, and Ideal Body Weight Calculator can give you a more complete picture. Soldiers who fail the body fat standard are placed in the Army Body Composition Program and must work to meet the requirement within a set time. Repeated failures can affect promotions and even lead to separation from the Army.
If you are working to bring your body fat down, tracking your daily nutrition is essential. Our Calorie Calculator, Macro Calculator, and TDEE Calculator can help you set the right targets. Monitoring your protein intake and staying properly hydrated with the help of our Water Intake Calculator also supports healthy fat loss while preserving lean muscle. For those focused on building muscle-to-fat ratio, the FFMI Calculator measures fat-free mass relative to height.
Tips for an Accurate Measurement
To get a good reading, measure at the right spot and pull the tape snug against the skin without pressing into it. Take each measurement three times and use the average. Measure in the morning before eating or drinking. Stand up straight and breathe normally. Round each measurement to the nearest half inch.
If you are also preparing for the Army Combat Fitness Test or other military fitness assessments, you may find our Air Force PT Calculator helpful for cross-branch comparisons. Tracking your heart rate zones, VO2 max, and calories burned during training can also help you optimize workouts to meet both fitness and body composition standards. Service members planning for the future may also benefit from our Military Retirement Calculator, TSP Calculator, and BAH Calculator for financial readiness alongside physical readiness.
