At What Age Does a Girl Stop Growing?

On average, girls reach their final adult height and stop growing by age 14 or 15, though this figure skews either younger or older depending on when puberty begins. Most girls experience a growth spurt between ages 10 to14, and a female’s rate of growth peaks around two years after puberty begins, which is usually around age 12.

Most girls begin menstruating only after their height growth rate has peaked, generally getting their first period around age 12.5. Once menstruation begins, girls usually grow 1 or 2 more inches, and reach their adult height by 14 or 15. During puberty, it’s important for girls to maintain regular exercise and a balanced diet in order to ensure proper growth and development.
