The age at which you stop growing varies depending on several factors, including genetics, sex, and the timing of puberty. Heres what we know:

• Girls: Girls tend to stop growing taller and reach their final adult height just two to two-and-a-half years after their first menstrual cycle, which typically occurs around age 12.5 years on average. However, the age at which girls stop growing can vary, and it can be earlier or later depending on when they entered puberty.

• Boys: Boys tend to start puberty around the age of 12 years, and most reach their adult height by the age of 16, but this can vary. In rare cases, some people may hit puberty in their late teens and continue to grow into their early twenties. Most boys will stop growing taller by age 16 and will usually have developed fully by 18.

Its important to note that every individual grows at different rates, and puberty begins and ends at different times for everybody. Additionally, external factors like diet and sleep can play a role in determining your health, but genetics are the biggest factor that determines how tall youll be.
