Weight Chart for Boys, 2 to 20 Years
Find your child's growth percentile based on age and weight.
This chart shows the percentiles of weight for boys from 2 to 20 years.
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 2 20 years. The left and right sides of the chart show weights.
The chart shows that at age 2 95% of boys are less than 34 pounds (about 15 kilograms) and 5% are less than 23 pounds (11 kg). At age 20 95% of boys are less than 212 pounds (about 96 kg) and 5% are less than 123 pounds (56 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 boy 90 pounds (41 kg) and 12 years old is very near the 50th percentile.
Consult your doctor if you are concerned about your child's weight.
