The last stage of puberty for a girl, Tanner Stage 5, marks the end of physical development, where the body reaches full maturity, reproductive organs are fully developed, and menstrual cycles typically become regular, usually occurring a couple of years after the first period (menarche). While growth slows, some may continue to grow taller until age 18-20, and the body achieves adult proportions.
For the majority of girls, puberty typically ends between the ages of 14 and 16, lasting around two to five years in total, but this can vary. Some girls might notice that their development finishes earlier, while others may continue to experience changes into their late teens.
Most females will start puberty when they're 8 to 13 years old, and most males will start between 9 and 14. But it can also be normal to start earlier or later. Hormones from the brain trigger the start of puberty.
Typically, breast development begins around age 8 to 13, with the most rapid growth occurring during early adolescence. By the age of 15 to 17, most girls have reached their adult breast size, although some may continue to experience minor changes into their early twenties.
"Most girls grow another one to two inches after getting their period, but increased height beyond that is less common," says the American Academy of Pediatrics (AAP). Opens a new window Girls typically stop growing earlier than boys because they start puberty earlier than boys.
Armpit hair is self-explanatory. Any amount will do. At this point, a girl will probably start her periods within 3-6 months, if she hasn't already. It also occurs right after the growth spurt of adolescence.
In your teens to mid-20s, your mind and body are going through a lot. You will experience changes in your skin, height, breasts, along with your menstrual cycle. You're also navigating an evolving identity, new relationships, and additional forms of stress — both positive and overwhelming.
Between the ages of 8 and 13, girls typically experience:
Genetics and environment both play a role in triggering menarche: Heredity: Your genes influence when you get your first period. People commonly get their periods when their mother did. Hormones: Hormones in your brain and your sex organs regulate your menstrual cycle and play a role in menarche, too.
In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18. However, in some cases, breasts can continue to grow into a woman's early 20s.
When puberty ends at around the age of 15, your teen will have reached full physical maturity. Females' breasts usually settle into their adult size and shape, and periods start to regulate. The reproductive organs and genitals will fully develop, while the hips, thighs and buttocks fill out in shape.
In fact, many important factors significantly affect a person's growth, ranging from malnutrition to the use of medications. Some girls may experience delayed height growth due to certain health conditions, such as severe arthritis, growth hormone issues, or cancer.
Does delayed puberty make you taller? It's difficult to predict how delayed puberty might affect your child's adult height. Some adolescents reach an adult height that's shorter than expected based on their biological parents' height. But for other adolescents, delayed puberty doesn't seem to affect their adult height.
Tweens and teens typically experience their biggest growth spurts during puberty. For girls, this often begins between ages 9–11, and for boys, around ages 11–13, although there's a wide range of normal.
Science doesn't show a direct correlation between sleep quality and height. However, sleep is an essential factor in your growth since that's the time of day when the growth hormone is released. So, while sleep doesn't directly increase height, it's still an integral part of your child's development.
Based on time trends, more recent birth cohorts have their menarche earlier and grow taller. However, women with earlier menarche reach a shorter adult height compared with women who have menarche at a later age.
While timelines can vary, most girls get their first period within 2 – 3 years after the development of breast buds. The average age for girls to get their first period in the United States is around age 12. It's important to emphasize that periods are a normal part of growing up.
You can safely swim during your period without increased risk of infection. Use a tampon or menstrual cup for the best protection while swimming. Swimming during your period can help ease cramps and bloating.
The ovaries release the female hormones estrogen and progesterone , which cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg (an egg that has joined with a sperm) to attach to and develop into a baby. If there is no fertilized egg, the lining breaks down and bleeds.

During Puberty Girls Grow Fast and Early
Unlike boys, their fastest rate of growth occurs early in puberty. They also gain more fat than boys in preparation for their menstrual cycle. They go from gaining about 5 pounds a year before puberty, to 12-23 pounds during puberty as shown below.
Five signs you've stopped growing in height as a female include slowed or no height gain for a year, fully developed secondary sexual characteristics (breasts, pubic/underarm hair), a loss of "baby fat" and more adult-like facial features, reaching full breast and hip development, and having your menstruation stabilize a couple of years after starting, indicating growth plates are closing.
