Staying within the standards of AR 600-9 (The Army Body Composition Program) is no longer just about stepping on a scale. As of January 1, 2026, the U.S. Army has fully implemented the most significant changes to body composition standards in decades.
Whether you are a Soldier trying to avoid a flag or a leader conducting a height and weight screening, understanding the transition to the Waist-to-Height Ratio (WHtR) and the 540 ACFT Exemption is critical for career progression.
What is AR 600-9? (Definition & Purpose)
AR 600-9 is the official Army Regulation that governs the Army Body Composition Program (ABCP). Its primary goal is to ensure all Soldiers maintain an optimal level of physical readiness, health, and professional military appearance.
Historically, the regulation relied on Body Mass Index (BMI) and a multi-site tape test (neck, waist, and hips). However, the 2026 updates move away from these “legacy” methods in favor of scientifically validated measurements that better account for lean muscle mass.
Key 2026 Updates: The New Body Composition Standards
The most drastic change in 2026 is the adoption of the 0.55 Waist-to-Height Ratio (WHtR) as the primary screening tool for Soldiers who exceed weight-for-height table limits.
1. The 0.55 Waist-to-Height Ratio (WHtR) Rule
The Army has replaced the complex multi-site “tape test” with a streamlined calculation. Your waist circumference (measured at the belly button) is divided by your height.
- The Standard: A Soldier’s WHtR must be less than 0.55.
- The Math: $\text{Waist (inches)} \div \text{Height (inches)} = \text{Ratio}$.
- Example: If you are 70 inches tall, your waist must be 38.5 inches or less ($70 \times 0.55 = 38.5$).
2. The 540 ACFT Exemption (Performance-Based)
The Army now rewards high-performing athletes regardless of their “bulk.” If you are a powerhouse on the ACFT, you might not even need to be taped.
- Requirement: A score of 540 points or higher on the record ACFT.
- Minimums: You must score at least 80 points in every event.
- Benefit: Soldiers meeting this criteria are exempt from body fat assessment, even if they exceed the weight-for-height table.
3. One-Site Tape Method Only
The “Legacy” tape test (neck and hips) has been officially phased out. All Soldiers are now measured using the One-Site Abdominal Circumference method.
New 2026 Measurement Procedures
To ensure accuracy and fairness, the Army has standardized how measurements are taken.
Height and Weight Screening
Soldiers are first screened against a simplified weight-for-height table. If a Soldier exceeds the weight allowed for their height, they proceed to the tape test.
| Height (Inches) | Max Weight (Male 17-20) | Max Weight (Female 17-20) |
| 60″ | 139 lbs | 122 lbs |
| 64″ | 158 lbs | 149 lbs |
| 68″ | 179 lbs | 168 lbs |
| 72″ | 200 lbs | 189 lbs |
The New Tape Test Process
- Placement: The tape is placed horizontally around the abdomen at the level of the navel (belly button).
- Tension: The tape must be snug but not compress the skin.
- Repetition: Three measurements are taken. The average is used for the final calculation.
- Rounding: Measurements are rounded down to the nearest half-inch.
Supplemental Body Fat Assessments
If a Soldier fails the 0.55 WHtR screening, they are not immediately “flagged.” Under the 2026 guidelines, they can request a highly accurate supplemental assessment if equipment is available:
- DXA Scan: Dual-energy X-ray absorptiometry (The Gold Standard).
- InBody 770: Bioelectrical Impedance Analysis.
- The Bod Pod: Air displacement plethysmography.
If the supplemental scan shows the Soldier is within the body fat percentage for their age (e.g., 20% for males 17-20), they are considered within standards.
What Happens if You Fail? (ABCP Enrollment)
If you fail both the WHtR and the supplemental assessment, you will be enrolled in the Army Body Composition Program (ABCP).
The ABCP Timeline
- Day 1: Notification of enrollment and “Flagging” (Action code: K).
- Day 3: Soldier is counseled on the program requirements.
- Day 30: Soldier must meet with a dietitian or healthcare provider.
- Monthly: Soldiers must lose 3-8 lbs or 1% body fat per month to show “satisfactory progress.”
Note: Two consecutive months of unsatisfactory progress can lead to administrative separation (discharge) from the Army.
FAQs & Schema Markup (Common Questions)
How is the new Army tape test calculated in 2026?
The 2026 tape test uses the Waist-to-Height Ratio. Divide your waist circumference (at the navel) by your total height in inches. If the result is 0.55 or higher, you fail the initial screening.
Does a 540 ACFT score still exempt you from tape?
Yes. As long as you score at least 80 points in each of the six events, you are exempt from the body fat assessment regardless of your weight.
Can I appeal a failed tape test?
Yes. You are entitled to a supplemental assessment using a DXA scan or InBody 770 if the equipment is reasonably available at your installation.
What is the maximum body fat for a 30-year-old male?
Under the current AR 600-9 standards, a male aged 28-39 has a maximum allowable body fat percentage of 24% (or must pass the 0.55 WHtR).
Tips to Pass the AR 600-9 Tape Test
- Hydrate Properly: Dehydration can actually cause your body to hold onto “water weight” around the midsection.
- Focus on the ACFT: The 540 exemption is the most secure way to ensure you are never flagged.
- Posture Matters: During the height measurement, standing “tall” can slightly improve your ratio.
- Avoid the “Quick Fix”: Plastic wraps or “sweat belts” only provide temporary results and can be dangerous.

Conclusion
The NEW AR 600-9 Updates for 2026 represent a shift toward performance and metabolic health. By moving to the Waist-to-Height Ratio, the Army has simplified the process while making it harder to “cheat” the tape with neck exercises.
