Puberty & Growth: When Do Boys & Girls Stop Growing?

The average age for boys to stop growing is between 16 and 18 years old, while for girls it's between 14 and 16 years old. However, there is a wide range of normal variation, and some people may stop growing earlier or later than this.

There are a number of factors that can affect how tall you will be, including genetics, nutrition, and overall health. If you are concerned about your height, you can talk to your doctor or a registered dietitian.
