Normal Weight Range for a Two-Year-Old

A healthy weight for a 2-year-old isn't an exact number you can track, but it's a range of weight that varies, depending on genetic factors and on your child's age in months. Understanding how average weight and growth charts applies to your child can help relieve anxiety, while also providing a guide for when it's time to raise concerns with your pediatrician.

Normal Weight Ranges

The normal weight range for a 2-year-old depends on gender and the age in months, according to the growth charts provided by the Centers for Disease Control and Prevention. At 24 months, boys can vary from 28 pounds in the 50th percentile to 35 pounds in the 97th percentile, and still fall within the normal, healthy range. Girls’ weights range from an average of 22 pounds in the 50th percentile to 33 pounds in the 97th percentile. At 30 months, weight ranges between these two percentiles average 30 to 37 pounds for boys and 29 to 36 pounds for girls. If your child's weight falls above the 5th percentile and is progressing steadily upward, chances are his growth rate is normal.

Children who have an average weight at or below the 5th percentile or above the 97th percentile on the growth charts often follow a healthy growth pattern. A 24-month-old boy below 23 pounds or a girl below 21 pounds is in the 3rd to 5th percentile. Genetics plays a major role in average weight, advices Mary L. Gavin, M.D., at Smaller or larger parents tend to have children who follow these growth patterns. Another normal growth pattern called Constitutional Growth Delay, or delayed puberty, can also cause:

  • slower-than-average weight gain between 6
  • 36 months
  • which then resumes at a normal rate until puberty
  • where there is often another delay before they catch up with their peers
