The Army Body Fat Calculator is a tool used to determine if a service member meets the body composition standards set by the U.S. Army. It calculates body fat percentage based on physical measurements and compares the results against the Army's standards, which vary by age, gender, and service requirements.
This calculator is essential because the U.S. Army enforces body fat limits to ensure that soldiers maintain physical readiness and health. If a soldier exceeds the allowable body fat percentage, they may be subject to further fitness programs or administrative action.
How the Army Calculates Body Fat
The calculation follows guidelines from the Army Regulation (AR) 600-9 (The Army Body Composition Program). The formula uses these measurements:
For Men:
Height (in inches)
Neck circumference (in inches)
Abdomen circumference (measured at the navel)
For Women:
Height (in inches)
Neck circumference (in inches)
Waist circumference (at the narrowest point)
Hip circumference (at the widest point)
The Army uses these measurements along with age and gender to estimate body fat percentage.
