AR 600-9 Body Composition Standards and The DoD Tape Method
How the Department of Defense evaluates physical readiness through anthropometric equations.
Under Army Regulation 600-9 (The Army Body Composition Program - ABCP), physical fitness is deemed critical for operational readiness and battlefield resilience. Rather than relying solely on simple Body Mass Index (BMI), which frequently penalizes heavily muscled service members, the Department of Defense enforces the circumference tape test derived from the empirical Naval Health Research Center studies. As extensively detailed in the US Navy and Army Circumference Method documented on Wikipedia, anthropometric circumferences combined with stature provide a reliable field estimate of total adipose tissue without requiring dual-energy X-ray absorptiometry (DEXA) or hydrostatic weighing tanks.
Male Equation (AR 600-9)
Two-Site TapeMeasurements are taken in inches rounded to the nearest 0.5 inch. Neck is measured at the Adam's apple; abdomen is measured at the navel level after normal tidal exhalation.
Female Equation (AR 600-9)
Three-Site TapeMeasurements incorporate natural minimal waist circumference, greatest gluteal hip protrusion, and cervical neck circumference to accurately capture gynoid fat distributions.
| Age Category | Male Max Body Fat | Female Max Body Fat | Male Sample Screening Ceiling (70 in) | Female Sample Screening Ceiling (65 in) |
|---|---|---|---|---|
| Ages 17 – 20 | 20.0% | 30.0% | 180 lbs (81.6 kg) | 140 lbs (63.5 kg) |
| Ages 21 – 27 | 22.0% | 32.0% | 180 lbs (81.6 kg) | 140 lbs (63.5 kg) |
| Ages 28 – 39 | 24.0% | 34.0% | 180 lbs (81.6 kg) | 140 lbs (63.5 kg) |
| Ages 40 and Older | 26.0% | 36.0% | 180 lbs (81.6 kg) | 140 lbs (63.5 kg) |
* Note: Service members who meet initial height-weight screening tables are exempt from tape tests. Tape testing occurs exclusively when a soldier exceeds the screening ceiling during semi-annual weigh-ins, in conjunction with the United States Army Physical Fitness evaluation.
Frequently Asked Questions
Authoritative answers regarding military tape standards, testing protocols, and compliance.
What is the official US Army body fat formula under AR 600-9?
The US Army circumference method derives body fat from logarithmic tape measurements: for males, %BF = 86.010 × log10(abdomen - neck) - 70.041 × log10(height) + 36.76; for females, %BF = 163.205 × log10(waist + hip - neck) - 97.684 × log10(height) - 78.387.
How does the Army weight screening table relate to the tape test?
Soldiers who meet or fall below the screening weight-for-height table pass automatically without taping. Only soldiers exceeding the screening table weight ceiling undergo official tape testing under AR 600-9.
What are the maximum allowable body fat percentages by age in the US Army?
For males: ages 17-20 is 20%, 21-27 is 22%, 28-39 is 24%, and 40+ is 26%. For females: ages 17-20 is 30%, 21-27 is 32%, 28-39 is 34%, and 40+ is 36%.
Where should circumference measurements be taken for accurate results?
Measure neck just below the larynx (Adam's apple). For males, measure abdomen horizontally across the navel at the end of normal exhalation. For females, measure waist at the narrowest natural point and hips at the greatest posterior protrusion of the gluteal muscles.
