BMI (body mass index) is a measure of whether you're a healthy weight for your height. Use this BMI calculator to check the adults in your family. For children go to Weight Concern's Child and young person's body mass index (BMI) calculator.
This calculator should only be used by adults (pregnant or lactating women should not rely on these BMI readings), and no action should be taken based on its values other than to consult a suitably qualified person such as a physician.
The calculator will give you an idea of how your weight compares to common values. Body Mass Index (or BMI) is calculated as your weight (in kilograms) divided by the square of your height (in metres) or BMI = Kg/M2.
BMI weight ranges
- Less than 18.5 = Underweight
- Between 18.5 - 24.9 = Healthy Weight
- Between 25 - 29.9 = Overweight
- Over 30 = Obese
You are in the range.
