Child Growth Percentile Calculator (CDC & WHO)

Easily track your child’s growth by comparing their weight, height, and BMI to standardized growth charts from the CDC and WHO for children aged 2 to 20.

What is a Growth Percentile?

A growth percentile is a standard measure used by pediatricians to assess a child's growth compared to other children of the same age and gender. This calculator plots your child's measurements on official growth charts to determine their weight-for-age, height-for-age, and BMI-for-age percentiles.

How to Interpret Percentile Results

For example, if your child is in the 40th percentile for height, it means they are taller than 40% of children their age and gender, and shorter than 60%. The key is not the number itself, but tracking the trend of this number over time.
