Description and comments
This chart shows the Body Mass Index (BMI) percentiles for girls from 2 to 20 years old.
How to read the percentile chart
The curved lines show BMI percentiles. For example, the top curved line shows the 95% percentile, which means that 95% of children are at or under that value.
The bottom of the chart shows ages, from 2 to 20 years. The left and right sides of the chart show BMI values.
The chart shows that at age 2 years 95% of girls have a BMI less than 19.2 and 5% have one less than 14.4. At 20 years 95% of girls have a BMI less than 32, and 5% have one less than 17.8.
How to find your child's BMI percentile
First, find your child's BMI in BMI for Children.
Then on this page, find your child's BMI on either side of the chart, and read horizontally across until you reach the vertical line for your child's age. Then see where that point is among the percentile lines.
For example, a girl with a BMI of 18 at age 12 is just below the 50% percentile.
Childrens weight status
The BMI for children is calculated the same way as for adults. However, it is interpreted differently. Here are the CDC weight status classifications for use with the above table:
| Percentile | Weight Status |
|---|---|
| 95th-100th | Overweight |
| 85th-95th | At Risk of Overweight |
| 5th-85th | Normal |
| 5th or less | Underweight |
Consult your physician if you are concerned about your child's growth.
