BMI Calculator

Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use, so you may find the language more technical than the condition leaflets.

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
