Body Mass Index (BMI) is a measure of body fat, and in adults, a BMI above 25 but below 30 indicates overweight, while 30 or above is classified as obese. To view your child’s BMI on a UK standard chart (for ages 5 to 18 only), enter the required information and select the appropriate graph, noting that the resulting charts are subject to copyright and may not be reproduced 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 Paeheight and weight charts on this website to check your measurements.
