Body Mass Index Calculator

The National Health and Medical Research Council has endorsed the Body Mass Index (BMI) approach to determining an acceptable weight for height range for the population. The Australian Defence Force has subsequently adopted this approach.

The BMI is calculated by the formula: weight (kg) divided by height (in metres) squared, ie kg/m2, and is a guideline of an appropriate range of body weight with respect to minimising certain health risks.

You can calculate your own BMI by using the following BMI Calculator, and comparing it with the guidelines below.

Standard for Recruits

BMI less than 18.5. You will be assessed by the examining medical officer in order to determine whether you could cope with the demands of training.

BMI 18.5 to 30. You fall within the acceptable range for entry.

BMI 30 to 33. You fall within the acceptable range for entry however, your body fat percentage will also be calculated and recorded.

BMI above 33. Is not acceptable for entry into the ADF and you will be classified as medically unfit. Should you lose weight and meet the BMI standards you will be requested to provide evidence of maintaining this weight loss for at least 6 months.

Please note that the BMI result is indicative only, and there may be other factors that affect the result. An initial adverse BMI result or failing the pre-entry physical fitness test may not necessarily preclude you from into the ADF. However, some career paths apply stringent standards. For example some aircrew occupations must have a BMI between 18.5 to 29.9, however must have a body weight between 55kg and 105kg (in underwear).
