Average Child Height

What is the average height of a child in the UK?

A child’s height can vary a lot. One child can be quite a bit taller than the average height, whereas another child may be shorter. Children often go through growth spurts, and then tend to grow slowly in height when they get older. In the overview below you can see the average height of boys and girls at different ages.

The average height of children has seen a sharp increase over the past 100 years. This is mainly due to increasingly balanced diets. Therefore, children now are 1- 5% taller than children of the same age 50 years ago.
