U.S. Army Body Fat Calculator
Use this calculator to estimate your body fat percentage based on the U.S. Army's tape test methodology (AR 600-9). This method uses specific circumference measurements and height to determine body fat percentage for both male and female service members.

The U.S. Army places a significant emphasis on physical fitness and body composition as critical components of a Soldier's readiness. The Army Body Fat Calculator, based on the official Army Regulation (AR) 600-9, provides an estimate of an individual's body fat percentage using a method known as the "tape test." This method is a practical and standardized way to assess body composition across the force.
Why Body Fat Standards?
Maintaining appropriate body fat levels is crucial for military personnel for several reasons:
- Physical Performance: Optimal body composition contributes to better endurance, strength, and agility, which are essential for combat and daily duties.
- Health and Wellness: Excessive body fat can lead to various health issues, including cardiovascular disease, diabetes, and musculoskeletal problems, impacting a Soldier's long-term health and ability to serve.
- Professional Appearance: Adhering to body composition standards helps maintain a professional military image.
- Readiness: Soldiers who meet body fat standards are generally more prepared for the physical demands of deployment and operations.
The Army Tape Test Methodology
Unlike methods that use specialized equipment (like DEXA scans or hydrostatic weighing), the Army's tape test relies on simple circumference measurements. While not as precise as laboratory methods, it offers a consistent and field-expedient way to assess body fat. The measurements required differ slightly between males and females:
For Males:
- Height: Measured in inches.
- Neck Circumference: Measured at the point just below the larynx (Adam's apple), perpendicular to the long axis of the neck.
- Abdominal Circumference: Measured at the navel (belly button), ensuring the tape is horizontal. The measurement is taken at the end of a normal exhalation.
The formula for males uses the difference between the abdominal and neck circumference, along with height, to estimate body fat percentage.
For Females:
- Height: Measured in inches.
- Neck Circumference: Measured at the point just below the larynx, perpendicular to the long axis of the neck.
- Waist Circumference: Measured at the navel (belly button), ensuring the tape is horizontal. The measurement is taken at the end of a normal exhalation.
- Hip Circumference: Measured at the largest protrusion of the buttocks, with the tape horizontal.
The formula for females uses the sum of waist and hip circumferences minus the neck circumference, along with height, to estimate body fat percentage.
How to Use the Calculator
To use the calculator, simply select your gender and accurately input your height and the required circumference measurements in inches. The calculator will then apply the official Army formulas to provide an estimated body fat percentage.
Example Calculations:
Example 1: Male Soldier
- Gender: Male
- Height: 70 inches
- Neck Circumference: 16 inches
- Waist Circumference: 34 inches
Using the calculator with these inputs would yield an estimated body fat percentage of approximately 17.5%.
Example 2: Female Soldier
- Gender: Female
- Height: 65 inches
- Neck Circumference: 13 inches
- Waist Circumference: 29 inches
- Hip Circumference: 39 inches
Inputting these values into the calculator would result in an estimated body fat percentage of approximately 24.1%.
Important Considerations:
- Accuracy of Measurements: The accuracy of the calculator's output heavily depends on the precision of your input measurements. Ensure the tape measure is snug but not compressing the skin, and that measurements are taken at the correct anatomical landmarks.
- Individual Variation: While the tape test is standardized, individual body shapes and fat distribution can vary, leading to slight discrepancies compared to other body fat assessment methods.
- Army Standards: This calculator provides an estimate of body fat percentage. The actual determination of whether a Soldier meets Army body composition standards involves additional factors like age and specific maximum allowable body fat percentages, which are outlined in AR 600-9.
This calculator is a helpful tool for self-assessment and understanding the Army's body composition methodology. Always refer to official Army regulations and consult with a medical professional or unit leadership for official assessments and guidance.
