What Is the Average Height of a 2-Year-Old Child?

By Staff WriterLast Updated December 08, 2023

The average height of a child who is two years old is 31 inches. By the time a child is two, he should weigh around 28.4 pounds.

During a child’s second year, growth will start to slow. By the time a child is two, he will be approximately half of his adult height. The size of the child’s head will also be 90 percent of what his head size will be as an adult. While some children grow noticeably more or less than the average height for a two year old, the child’s steady growth is what matters most. A child’s slow growth may be due to his changing appetite, as two-year-olds are learning to feed themselves and enjoy more table foods.
