Girls develop faster than boys, but when do girls reach their max height? Turns out, it’s dependent on the age they get their first period.

When do Girls Stop Growing?

Girls hit their maximum growth spurt before menstruation begins, generally getting their first period around 12 1/2 years of age.

Once their period starts, girls typically gain another 1 to 2 inches in height, reaching their full adult height by age 14 or 15.

However there is a very broad range of time in which girls hit puberty-related growth spurts.

Many girls start puberty between ages of 8 and 13, and have a growth spurt between the ages of 10 and 14. During puberty, it’s important for girls to maintain regular exercise and a balanced diet in order to ensure proper growth and development.
