Your Body Mass Index
What it is & why it matters
Your Body Mass Index, or BMI, is a measure of body fat based on your height and weight.
It’s found by dividing your weight in kilograms by the square of height in meters. Don’t worry - there are charts and online calculators available to help you find your number. BMI can be used to help find out if a person might be overweight – but, it’s not the only factor to consider.
