At What Age do Girls Stop Growing?

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 and enter puberty.

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.

Tanner Stages of Puberty for Girls

Puberty is marked by distinct stages of physical development known as the Tanner stages, named after Professor James Tanner, a child development expert,

While the Tanner stages give average ages of puberty development, there is significant variation among children and teenagers. Parents and teens shouldn’t worry if they reach a stage of puberty earlier or later.

Tanner stage one: Before Puberty

This period is sometimes referred to as pre-pubertal.

Tanner stage two: Puberty Begins

  • In girls, puberty usually begins at around 11 years of age, although it can occur anytime between 8 and 14.
  • Girls grow taller about 3 inches per year during this stage
  • Breast buds develop
