Child and young person's

Body Mass Index (BMI) calculator

It is much more difficult to interpret weight in children than it is for adults. This is because children are still growing, so you need to take into account their age, height and gender. The weight for height calculator below will do this and will then tell you whether your child is in the healthy weight, overweight, or very overweight range. However it is important to remember these measures should only be used as a guide, as every child is different and children grow at different rates. If you have concerns about this, your doctor should be able to tell you more.

 Please enter the child/young person's age: 
 Please select male/female:
 Child's weight:  stones  pounds  or  kgs
 Child's height:  feet  inches  or  centimetres


DON'T FORGET THAT REGARDLESS OF BODY WEIGHT, EATING HEALTHILY AND DOING REGULAR PHYSICAL ACTIVITY ARE BOTH IMPORTANT FOR YOUR CHILD'S HEALTH AND DEVELOPMENT.
