About the Army Body Fat Calculation Method
The U.S. Army Body Fat Calculator uses a circumference-based method to estimate body fat percentage. This method, known as the "tape test," is officially used by the U.S. Army as part of their body composition screening process.
This calculation uses measurements of various body parts (neck, waist, and hip for women) to estimate body fat percentage based on the relationship between these circumferences and overall body composition.
How the Army Uses Body Fat Assessment
Soldiers who exceed the maximum weight for their height and age are subjected to body fat testing. If their body fat percentage exceeds the standard for their age and gender, they may be enrolled in the Army Body Composition Program and required to meet the standards within a certain timeframe.
Note: While the Army tape test is widely used for its simplicity and convenience, it's an estimation method and may differ from results obtained through other body fat measurement techniques like DEXA scans, hydrostatic weighing, or skinfold measurements.
Body Fat Categories for General Population
| Category | Men | Women |
|---|---|---|
| Essential Fat | 2-5% | 10-13% |
| Athletes | 6-13% | 14-20% |
| Fitness | 14-17% | 21-24% |
| Average | 18-24% | 25-31% |
| Obese | >25% | >32% |
Army Body Fat Calculation Formula
The U.S. Army uses specific formulas developed by the Department of Defense to calculate body fat percentage based on body circumference measurements.
For Men:
Body Fat % = 86.010 Ă log10(waist - neck) - 70.041 Ă log10(height) + 36.76
Where waist, neck, and height are in inches
For Women:
Body Fat % = 163.205 Ă log10(waist + hip - neck) - 97.684 Ă log10(height) - 78.387
Where waist, hip, neck, and height are in inches
Development of the Formula
These equations were developed based on research comparing circumference measurements to underwater weighing, which was considered the gold standard for body fat assessment. The formulas were designed to provide a reasonably accurate estimate while being practical for field use.
Limitations
Like all body fat estimation methods, the Army method has limitations:
- It may not be as accurate for individuals who are very muscular or have unusual body proportions
- The formula makes assumptions about fat distribution patterns that may not apply to everyone
- Measurement technique can significantly affect results
- It may be less accurate for individuals at the extremes of body composition
For the most accurate assessment of body composition, multiple methods should be used, ideally including more advanced techniques like DEXA scans when available.
Proper Measurement Technique
Accurate measurements are critical for obtaining valid body fat percentage results. According to Army standards, all measurements should be taken three times and averaged for the final calculation.
Height Measurement:
- Remove shoes
- Stand with heels together, back straight against a wall
- Look straight ahead (not up or down)
- Measure to the nearest 0.25 inch (0.5 cm)
Weight Measurement:
- Use a calibrated scale
- Wear minimal clothing
- Measure in the morning, after using the bathroom and before eating
- Record to the nearest 0.5 pound (0.25 kg)
Male Neck Measurement:
- Measure just below the larynx (Adam's apple)
- Tape should be perpendicular to the long axis of the neck
- Subject should look straight ahead with shoulders down (not hunched)
Male Waist Measurement:
- Measure at the level of the belly button (navel)
- Measure at the end of a normal, relaxed exhalation
- Arms should be relaxed at sides
- Tape should be parallel to the floor and snug but not compressing the skin
Female Neck Measurement:
- Measure just below the larynx (Adam's apple)
- Look straight ahead with shoulders down
- Place the tape perpendicular to the long axis of the neck
Female Waist Measurement:
- Measure at the narrowest point of the abdomen, usually between the bottom of the rib cage and the top of the hip bones
- If no obvious narrowest point, measure at the level of the belly button
- Measure at the end of a normal exhalation
Female Hip Measurement:
- Measure at the widest point of the buttocks
- Feet should be together
- The tape should be parallel to the floor
- Tape should be snug but not compressing the skin
Measurement Tips:
- Use a non-elastic, flexible measuring tape
- Measure directly against the skin, not over clothing
- Take each measurement 3 times and use the average
- Keep the tape snug but not tight (should not indent the skin)
- Stand in a relaxed position with weight evenly distributed
U.S. Army Body Fat Standards
The U.S. Army has established maximum allowable body fat percentages based on age and gender. Soldiers who exceed these standards may face administrative action and be required to participate in a weight management program.
| Age Group | Male | Female |
|---|---|---|
| 17-20 years | 20% | 30% |
| 21-27 years | 22% | 32% |
| 28-39 years | 24% | 34% |
| 40+ years | 26% | 36% |
Army Weight Screening Process
Before body fat testing is conducted, soldiers are first screened using height/weight tables. Only those who exceed the maximum weight for their height are required to undergo the body fat assessment.
The weight screening table is extensive. Generally, soldiers must meet the following standards:
- Males: Weight allowance increases with height, typically around 2-3 pounds per inch
- Females: Similar pattern but with a slightly lower weight allowance
- Age is also factored in, with increased allowances for older soldiers
Body Composition Program
Soldiers who exceed body fat standards are typically:
- Enrolled in the Army Body Composition Program
- Required to lose 3-8 pounds per month
- Required to participate in a supervised exercise program
- Given nutritional counseling
- Reevaluated monthly
- Expected to meet standards within a specific timeframe
Failure to meet body composition standards within the allotted time can result in administrative separation from the Army, depending on other factors such as performance and career history.
Important:
These standards may be updated periodically by the Department of Defense. For the most current official standards, refer to Army Regulation 600-9 (The Army Body Composition Program).
