Weight Chart for Boys, Birth to 36 Months

Find your child's growth percentile based on age and weight.

Description and comments

This chart shows the percentiles of weight for boys from birth to 36 months.

How to read the percentile chart

The curved lines show weight percentiles. For example, the top curved line shows the 95% 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 boys are less than 10 pounds (about 4.6 kilograms) and 5% are less than 5.5 pounds (2.6 kg). At 36 months (3 years) 95% of boys are less than 38 pounds (about 17.2 kg) and 5% are less than 26.5 pounds (12 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 28 pounds (12.8 kg) and 24 months old is just at the 50% percentile.

Consult your physician if you are concerned about your child's weight.
