What is BMI?

Body Mass Index (BMI) is a number calculated from weight and height (weight[kg]/height[m]²).

What is BMI-for-age percentile?

The BMI number is plotted on a CDC BMI-for-age growth chart (for either girls or boys) to get a percentile ranking. BMI-for-age percentile shows how your child compares to that of other children of the same age and sex.
