Calculation Methods
2023 One-Site Tape Test (Current)
Since June 2023, the Army implemented a simplified one-site tape test requiring only abdominal circumference and body weight.
Formulas:
- Men: BF% = -26.97 – (0.12 × weight in lbs) + (1.99 × abdomen in inches)
- Women: BF% = -9.15 – (0.015 × weight in lbs) + (1.27 × abdomen in inches)
Measurement Instructions:
- Measure abdominal circumference at navel level
- Take three measurements and use the average
- Round to the nearest 0.5 inch
Legacy Multi-Site Tape Test
The traditional method uses neck, waist (and hip for women), and height measurements.
Formulas:
- Men: BF% = 86.010 × log₁₀(waist – neck) – 70.041 × log₁₀(height) + 36.76
- Women: BF% = 163.205 × log₁₀(waist + hip – neck) – 97.684 × log₁₀(height) – 78.387
Body Fat Standards
| Age Group | Males | Females |
|---|---|---|
| 17-20 | 20% | 30% |
| 21-27 | 22% | 32% |
| 28-39 | 24% | 34% |
| 40+ | 26% | 36% |
ACFT Exemption
Soldiers who score 540 or higher on the Army Combat Fitness Test (ACFT) with a minimum of 80 points in each event are exempt from the body fat assessment.
Supplemental Assessment
If you fail the tape test, you may request a supplemental body fat assessment using:
- Dual X-ray Absorptiometry (DXA)
- InBody 770
- Bod Pod
Frequently Asked Questions
Q: Which method should I use? A: The 2023 One-Site method is the current official standard. The Legacy method is still recognized and may be used for comparison.
Q: How accurate is the tape test? A: The tape test has an estimated error margin of ±3-4%. More precise methods like DXA scanning are available as supplemental assessments.
Q: What if I'm close to the maximum? A: If you're within 2% of the maximum, consider improving diet and exercise. The ACFT exemption is also an option if you can achieve a score of 540+.
