This calculator measures Body Mass Index (BMI), which is a measure of body fat. The calculator can be used for anyone from two to 20 years of age.

Please note:

Always see your doctor if you are concerned about your child's growth.
The body mass index (BMI) is used to assess whether a person is underweight, normal weight or overweight.
As children grow, their amount of body fat changes and so will their BMI. That's why a BMI calculation for a child or adolescent must be compared with age and gender percentile charts.
