What Are Percentiles? Percentiles are measurements that show where a child is compared with others. On the growth charts, the percentiles are shown as lines drawn in curved patterns. When doctors plot a child's weight and height on the chart, they see which percentile line those measurements land on.
Why Percentiles Are Not Like the Grades in School. What we want from a growth grid is to really map out the ideal growth for children. This isnât like grades in school. When your child comes in at the 10th percentile, itâs really no better or worse than coming in at the 90th. What we care about most is the trend at which your baby or child gains weight, height, or head circumference. After age 2, you can use the growth chart to expand between the ages of 2 and 20.
