The Body Mass Index (BMI) is a useful weight loss tool that has been used for many years by health professionals to estimate the body fat content and to assess whether a person’s weight is healthy or not. In this section, you can read about BMI and use our BMI Calculator to assess your weight.
Adult, Children and Teen BMI Calculator
The BMI calculator provided here is suitable for adults only. For children and teens, the BMI calculation method is slightly different than the one provided here. For a children and teen BMI calculator please visit the Centers for Disease Control and Prevention.
You can calculate your BMI value by dividing your weight (in kilograms) by your height (in meters) squared. For example, if your weight is 74Kg and your height is 1.80m than your BMI would be 22.84 (i.e. 74/(1.80×1.80)). Alternatively, you can use our BMI calculator to estimate your BMI.
The BMI values are classified into the following categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI = 18.5 – 25
- Overweight: BMI = 25 – 30
- Obese: BMI = 30 – 40
- Very obese: BMI greater than 40
The BMI value is not an accurate measurement for pregnant or breastfeeding women. It’s also not accurate if you’re an athlete or very muscular. In this case, your body muscles weigh more than your body fat which can lead to a higher BMI even if you have a healthy level of body fat.
