About the Army Tape Test

The Army Body Fat Calculator uses the circumference method (also known as the "tape test") to estimate body fat percentage based on measurements of specific body parts.

For males, the calculation uses neck and waist measurements. For females, it uses neck, waist, and hip measurements. This method is detailed in Army Regulation 600-9.

While not as accurate as methods like DEXA scans or hydrostatic weighing, the tape test provides a practical, field-expedient means to estimate body fat percentage.

Army Body Composition Programme

The Army Body Composition Programme (ABCP) establishes the body fat standards that soldiers must maintain. Soldiers who exceed both weight and body fat standards may be enrolled in the Army Body Composition Programme.

Screening Process

Height and Weight Screening: Initial screening compares a soldier's weight to the standard weight allowance for their height.
Body Fat Assessment: If a soldier exceeds the weight allowance, a body fat measurement is taken using the circumference method.
Standards Evaluation: The calculated body fat percentage is compared against the maximum allowable percentage based on age and gender.

Tips for Meeting Standards

Nutrition: Follow a balanced, calorie-appropriate diet with adequate protein, complex carbohydrates, and healthy fats.
Physical Training: Combine cardiovascular exercise with strength training to build muscle and reduce body fat.
Sleep and Recovery: Ensure adequate rest between workouts and get 7-8 hours of sleep daily.
Hydration: Maintain proper hydration levels to support metabolism and physical performance.

Important Notes

This calculator provides an estimate based on the Army methodology but may not match official measurements.
Body fat percentage alone is not a complete indicator of health or fitness.
For official Army assessments, refer to AR 600-9 and consult with your chain of command.
