Find your child's growth percentile based on age and height.
This chart shows the percentiles of length (height) for girls from birth to 36 months.
The curved lines show height percentiles. For example, the top curved line shows the 95% percentile, which means that 95% of children are at or under that height.
The bottom of the chart shows ages, from birth to 36 months. The left and right sides of the chart show heights.
The chart shows that at birth 95% of girls are less than 21.5 inches (about 54 centimeters) and 5% are less than 18 inches (45 cm). At 36 months (3 years) 95% of girls are less than 40 inches (about 102 cm) and 5% are less than 34.5 inches (88 cm).
Find your child's height on either side, 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 30 inches (76 cm) tall and 12 months old is just above the 75% percentile.
Consult your physician if you are concerned about your child's height.
