Find your child's growth percentile based on age and height.
This chart shows the patterns of height (length) and weight for children from birth to 36 months.
The top set of curved lines shows length percentiles. For example, the top curved line shows the 95% percentile, which means that 95% of children are at or under that height. The lower set of curved lines shows weight percentiles.
The top of the chart shows ages, from birth to 36 months. The left and right sides of the chart show heights in the upper section and weights in the lower section.
The chart shows that at birth 95% of boys are less than 22 inches (about 55 centimeters) and 5% are less than 18 inches (45 cm). At 36 months (3 years) 95% of boys are less than 41 inches (about 103 cm) and 5% are less than 35 inches (89 cm).
Find your child's height on the left 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 boy 30 inches (76 cm) tall and 12 months old is just above the 50% percentile.
Consult your physician if you are concerned about your child's growth.
