Calculate a Child’s BMI

Body Mass Index (BMI) is a measure of how much of your body is made up of fat. In adults, if your BMI is above 25, but below 30 you are overweight, 30 or above and you are obese. To view your child’s BMI on a UK standard chart, enter the requested information and select the appropriate graph. Please note this will plot 5-18 yrs only. The graphs displayed as a result of entering this data are subject to copyright and must not be used for reproduction without permission.

BMI health status seen in isolation can be misleading. If your child appears to be very underweight or overweight then please consult a health professional. You may wish to utilise the height and weight charts on this website to check your measurements
