Understanding the Body Mass Index or BMI BMI is determined by your weight in kg divided by your (height in metres)2. It is designed for men and women over the age of 18. A healthy BMI is between 20 and 25. A result below 20 indicates that you may be underweight; a figure above 25 indicates that you may be overweight.

1. Enter your height in centimetres (without shoes on):   cm 2. Enter your weight in kilograms (without clothes):   kg

Your BMI result:

You could afford to gain a little weight. 20 - 25 ACCEPTABLE You have a healthy weight for your height. 26 - 30 OVERWEIGHT You are over optimum weight for your height. You may be facing health problems, so losing some weight would be a good idea. 31 + OBESE You are over optimum weight for your height.

These BMI measures are not suitable for Aboriginal and Torres Strait Islander peoples, whose healthy BMI range may be lower than that for Australians of European descent. This is due to their ancestry as traditional hunter-gatherers who were lean and physically fit.
