Weight Chart for Girls, Birth to 36 Months
Find your child's growth percentile based on age and weight.
For children under 2, the CDC now recommends the World Health Organization (WHO) growth standards. This chart is the CDC's earlier version. Ask your child's doctor which chart they use, or see the WHO-based charts from the CDC.
This chart shows the percentiles of weight for girls from birth to 36 months.
How to read the chart
The curved lines show weight percentiles. For example, the top curved line shows the 95th percentile, which means that 95% of children are at or under that weight.
The bottom of the chart shows ages, from birth to 36 months. The left and right sides of the chart show weights.
The chart shows that at birth 95% of girls are less than 9 pounds (about 4.2 kilograms) and 5% are less than 5.5 pounds (2.6 kg). At 36 months (3 years) 95% of girls are less than 39.5 pounds (about 17.6 kg) and 5% are less than 25.5 pounds (11.6 kg).
Find your child's weight 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 26 pounds (11.8 kg) and 18 months old is just at the 75th percentile.
Consult your doctor if you are concerned about your child's weight.
About this chart
The chart comes from the Centers for Disease Control and Prevention's National Center for Health Statistics. We converted it from the CDC's PDF into a web image. Print the PDF version if you'd like to record your child's measurements.
