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.
