BMI Calculator Army

The Army Body Fat Calculator is based on the United States Army Medical Fitness Standards, which were published on June 27, 2019. This calculator will compute body fat % and decide whether the calculated body fat percentage meets the army recruitment standard, the standard after joining the army, or the most strict standard of meeting the Department of Defense goal. Take the average of at least three measurements to ensure accuracy. Measure to the closest 1/2 or 1/4 inch if feasible.


Army BMI Standard

Body Mass Index (BMI): A minimum height of 148cm is required (except for employments that involve driving, when the minimum height is 158cm). Your weight and height should be in proportion.

• Adult entrance (male): BMI must be between 18 and 28, but can be up to 32 with further assessment by the Army Doctor. (Male candidates with a BMI of 28 to 32 must have a waistline measurement of less than 94cm.)

• Female adult entry: BMI must be between 18 and 28, but can be up to 30 with additional assessment by the Army Doctor. (Women with a BMI between 28 and 30 must have a waistline measurement of less than 80cm.)

• To be considered for junior entrance, your BMI must be between 17 and 27.

BMI Calculating Formula

The BMI (Body Mass Index) is computed by adding the weight in kilograms (kg) by the square height in meters (m):

BMI(kg/m2) = mass(kg) / height2(m)

The BMI (Body Mass Index) in kilograms per square meter is computed by adding the mass in pounds (lbs) by the square height in inches (in) times 703:

BMI(kg/m2) = mass(lb) / height2(in) × 703


The BMI is commonly used to determine how far a person’s body weight deviates from what is considered normal or acceptable for their height. Body fat (adipose tissue) may account for some of the weight gain or loss, but other characteristics such as muscularity have a substantial impact on BMI (see discussion below and overweight).

A BMI of less than 18.5 is considered underweight by the WHO and may suggest malnutrition, an eating disorder, or other health issues, whereas a BMI of 25 or more is considered overweight, and a BMI of greater than 30 is considered obese. These BMI ranges are solely useful as statistical classifications.

BMI CategoryBMI Range
Health risk
Underweight18.4 and belowMalnutrition risk
Normal weight18.5 – 24.9Low risk
Overweight25 – 29.9Enhanced risk
Moderately obese30 – 34.9Medium risk
Severely obese35 – 39.9High risk
Very severely obese40 and aboveVery high risk

BMIs below 20 and above 25 have been linked to an increased risk of all-cause death, with the risk increasing as one moves away from the 20–25 range.
