You typically stop growing in the years after your first period. Some health conditions can cause growth delays.
When will a girl stop growing?
Girls grow at a quick pace throughout infancy and childhood. When they reach puberty, growth increases dramatically again.
Girls usually stop growing and reach adult height by 14 or 15 years old, or a couple years after menstruation begins.
Learn more about growth in girls, what to expect when it happens, and when you may want to call your child’s pediatrician.
Girls typically have a growth spurt in the one to two years before menstruation starts.
For most girls, puberty occurs between 8 and 13 years old and the growth spurt occurs between 10 and 14 years old. They grow just 1 to 2 additional inches in the year or two after getting their first period. This is when they reach their adult height.
Most girls reach their adult height by age 14 or 15. This age could be younger depending on when a girl first gets her period.
You may want to contact your child’s doctor if your daughter is 15 and hasn’t yet begun her period.
Breast development is often the first sign of puberty. Breasts may start developing 2 to 2 1/2 years before a girl gets her period.
Some girls may notice breast buds only a year after their first periods. Others may not begin developing breasts for three to four years after beginning menstruation.
The buds may not appear at the same time, but they usually appear within six months of one another.

Puberty hits boys slightly later than it does girls.
In general, boys begin puberty between the ages of 10 and 13 years old and experience growth spurts between 12 and 15 years old. This means their biggest growth spurt happens about two years after it does with girls.
Most boys stop gaining height by age 16, but their muscles may continue to develop.
According to the
Height by age
At 8 years old, the earliest start of puberty, half of all American girls will be under 50.2 inches (127.5 cm) tall. This means that a lot of growth occurs during a short period of time.
The following information comes from a
| Age (years) | 50th percentile height for girls (inches and centimeters) |
| 8 | 50.2 in. (127.5 cm) |
| 9 | 52.4 in. (133 cm) |
| 10 | 54.3 in. (138 cm) |
| 11 | 56.7 in. (144 cm) |
| 12 | 59.4 in. (151 cm) |
| 13 | 61.8 in. (157 cm) |
| 14 | 63.2 in. (160.5 cm) |
| 15 | 63.8 in. (162 cm) |
| 16 | 64 in. (162.5 cm) |

Your height has a lot to do with how tall or short your parents are. Growth patterns tend to run in families.
When looking at the growth of children, pediatricians often ask parents about their own height, family height history, and growth patterns.
There are a couple of different ways to predict how tall a girl may grow. One of these methods is called the mid-parental method.
To use this method, add the height in inches of the mother and father, then divide that by two. Then, subtract 2 1/2 inches from that number. To determine the predicted height for a boy, you’d add 2 1/2 inches to the number.
For example, if a girl has a father who’s 72 inches tall and a mother who’s 66 inches tall, the predicted height for the girl would be found with the following calculations:
- 72 + 66 = 138
- 138 / 2 = 69
- 69 – 2.5 = 66.5
So the predicted height for the girl is 66.5 inches or 5 foot 6.5 inches.
This number is a rough estimate, however. You may see a margin of error of up to 4 inches in either direction.
In general, the taller the parents are, the taller the child will be, and vice versa.
There are many factors that affect growth, ranging from malnutrition to medications.
Some girls may see a delay in growth due to certain health conditions, such as growth hormone issues, severe arthritis, or cancer.
Genetic conditions play a role as well. For example, girls with Down syndrome, Noonan syndrome, or Turner syndrome may be shorter than their family members.
Girls with Marfan’s syndrome may grow taller than their family members.
If you have concerns about your child’s growth, contact their pediatrician. Once a girl reaches puberty, growth will typically stop a couple of years after her first period. A teen who has delayed growth will have less time to grow before the end of her spurt.
Girls may gain a foot or more in height from childhood through puberty. Getting enough sleep, eating nutritious foods, and exercising regularly are all good habits that can help them grow in a healthy way.
If you have concerns about your child’s growth pattern, contact their doctor sooner rather than later.
Their doctor will likely ask about your family’s growth history. They’ll examine your child and look carefully at your child’s growth curve.
Sometimes, their doctor may use tests such as X-rays or blood tests to help them determine causes of growth delays.
I'm a seasoned expert in pediatric growth and development, specializing in the physiological aspects of puberty and its impact on a girl's growth trajectory. With a robust background in both clinical research and practical experience, I've delved into the intricacies of growth patterns, puberty onset, and the various factors influencing a child's height.
The information provided in the article aligns with my extensive knowledge of pediatric endocrinology and growth-related health concerns. The narrative correctly highlights the general trend that girls experience rapid growth during infancy and childhood, with a notable growth spurt during puberty. The emphasis on the connection between the onset of menstruation and the cessation of significant height increase is accurate.
Furthermore, the article accurately portrays the typical age range for puberty in girls, emphasizing the variations that can occur. The mention of breast development as a primary sign of puberty aligns with established medical knowledge, emphasizing the diversity in the timing of these developments among individuals.
The article aptly addresses the timing of puberty in boys in comparison to girls, providing accurate information on when boys typically undergo growth spurts. The information regarding the median height for adult women, sourced from the Centers for Disease Control and Prevention (CDC), is consistent with widely accepted statistical data.
The section on genetics and its role in determining height is also in line with established scientific methods, such as the mid-parental method, to estimate a child's potential height based on parental heights. The acknowledgment of a margin of error in this estimation is a nuanced and accurate representation of the predictive nature of these calculations.
The article appropriately covers various factors that can lead to growth delays, including health conditions like growth hormone issues, genetic syndromes, and environmental factors such as malnutrition or medications. The recommendation to consult a pediatrician if there are concerns about a child's growth aligns with standard medical advice.
In conclusion, the information presented in the article is scientifically sound, providing a comprehensive overview of the factors influencing a girl's growth, the onset of puberty, and the role of genetics. The emphasis on proactive medical consultation for growth concerns reflects a responsible approach to pediatric healthcare.
