When Do Girls Stop Growing?A Complete Guide to Female Growth Patterns
Understanding when girls stop growing, how puberty timing affects final height, and what parents can expect at each stage of development.
If you're the parent of a growing daughter, you've probably wondered: when will she stop growing? It's a question that comes up frequently, whether you're buying clothes that fit for more than a few months, tracking her development compared to peers, or simply curious about her eventual adult height. The answer involves understanding the intricate relationship between puberty, hormones, and bone development.
The short answer is that most girls stop growing between ages 14 and 16, typically 2-3 years after their first menstrual period (menarche). However, this timeline varies significantly based on when puberty begins, genetics, nutrition, and overall health. This comprehensive guide will help you understand exactly what's happening during your daughter's growth journey and what to expect at each stage.
Key Takeaway
Girls typically stop growing 2-3 years after their first period, usually between ages 14-16. The average girl grows only 1-2 inches after menarche. Early puberty often means less total growth, while late bloomers may continue growing longer but typically reach similar final heights.
What You'll Learn
Average Age Girls Stop Growing
According to pediatric growth research, most girls reach their final adult height between ages 14 and 16. However, this can range from as early as 13 to as late as 18, depending on individual factors. The key determinant is not chronological age, but rather where a girl is in her pubertal development.
Female Growth Timeline Overview
| Age Range | Growth Phase | Typical Growth Rate |
|---|---|---|
| Birth - 2 years | Rapid infant growth | 10 inches first year, 5 inches second year |
| 2 - 8 years | Steady childhood growth | 2-2.5 inches per year |
| 8 - 13 years | Pubertal growth spurt | 3-3.5 inches per year at peak |
| Post-menarche | Final growth phase | 1-2 inches total remaining |
| 14 - 16 years | Growth completion | Minimal to none |
The average height for adult women in the United States is approximately 5 feet 4 inches (163 cm). However, "normal" adult female height ranges from about 4'11" to 5'9" (150-175 cm). Your daughter's genetic potential, largely determined by parental heights, plays the biggest role in where she'll fall within this range.
Female Puberty and Growth Timeline
Understanding the sequence of pubertal changes helps predict growth patterns. Puberty in girls follows a predictable sequence, though timing varies considerably. The entire process typically takes 2-5 years from first signs to completion.
Stage 1: Thelarche (Breast Development) - Ages 8-13
- Usually the first sign of puberty in girls
- Average age of onset: 10-11 years
- Growth spurt typically begins within 6 months
- Height velocity increases from baseline of 2 inches/year
Stage 2: Peak Height Velocity - Ages 10-14
- Maximum growth rate: 3-3.5 inches (7.5-9 cm) per year
- Occurs about 6-12 months before first period
- Typically happens 1-2 years after breast development begins
- Girls gain about 8-10 inches during entire puberty
Stage 3: Menarche (First Period) - Ages 10-16
- Average age: 12.4 years in the United States
- Signals that peak growth has already passed
- Typically occurs when about 95% of height is achieved
- Growth significantly slows after this point
Stage 4: Growth Completion - Ages 14-16
- Occurs 2-3 years after menarche on average
- Growth plates (epiphyses) close
- Final height is reached
- Body composition changes continue but height stabilizes
Important Timing Note
The female growth spurt typically occurs earlier in puberty compared to boys. While boys experience their peak growth velocity later in puberty (often at ages 13-15), girls reach peak height velocity about 6-12 months before their first period, usually around ages 11-12. This is why girls are often taller than boys during middle school years, even though boys typically end up taller as adults.

View on AmazonHow First Period (Menarche) Affects Growth
The first menstrual period is a significant milestone in understanding when a girl will stop growing. Menarche signals that the body has produced enough estrogen to trigger menstruation, and this same estrogen is responsible for the eventual closure of growth plates.
The Menarche-Height Connection
Peak Growth Occurs Before Menarche
The fastest growth rate happens 6-12 months before the first period, not after.
Limited Growth Remaining
After menarche, most girls grow only 1-2 inches (2.5-5 cm) in total.
95% Rule
By the time of first period, girls have typically reached 95-98% of their adult height.
2-3 Year Window
Growth continues slowly for about 2-3 years after menarche before stopping completely.
A common misconception is that girls grow significantly after their first period. In reality, the opposite is true: menarche is a late pubertal event that signals the beginning of the end of growth. If your daughter got her period at age 11, she has likely already experienced her fastest growth and will be close to her final height by age 13-14.
Estimated Growth After Menarche by Age
| Age at First Period | Expected Additional Growth | Typical Age Growth Stops |
|---|---|---|
| Age 10 | 2-3 inches (5-7.5 cm) | 12-13 years |
| Age 11 | 2-2.5 inches (5-6 cm) | 13-14 years |
| Age 12 | 1.5-2 inches (4-5 cm) | 14-15 years |
| Age 13 | 1-1.5 inches (2.5-4 cm) | 15-16 years |
| Age 14+ | 0.5-1 inch (1-2.5 cm) | 16-17 years |
Growth Plate Closure in Girls
Growth plates (also called epiphyseal plates or physes) are areas of cartilage located at the ends of long bones. These plates are where bone growth occurs during childhood and adolescence. Understanding growth plate closure helps explain why height growth eventually stops.
How Growth Plates Work
- Cartilage cells in growth plates divide and multiply
- New cartilage is converted to bone (ossification)
- This process adds length to bones
- Growth hormone and sex hormones regulate this process
What Causes Closure
- Estrogen triggers growth plate closure
- Higher estrogen levels = faster closure
- Explains why girls stop growing earlier than boys
- Once closed, no further height growth is possible
In girls, growth plates typically begin closing around ages 13-15 and are usually fully closed by ages 15-17. The bones of the hands and feet close first, followed by the long bones of the arms and legs, and finally the spine. A bone age X-ray can determine how much growth potential remains by examining the degree of growth plate closure.
The Role of Estrogen
Estrogen plays a paradoxical role in female growth. Initially, it stimulates the growth spurt during puberty. However, sustained estrogen exposure eventually causes the growth plates to fuse (close), ending height growth. This is why girls who enter puberty early (and thus are exposed to estrogen earlier) often end up shorter than those who develop later, despite initially appearing taller than their peers.
Early vs Late Bloomers: How Puberty Timing Affects Final Height
The timing of puberty has a significant impact on growth patterns and, potentially, final adult height. Understanding the differences between early and late bloomers can help parents set realistic expectations and identify when medical evaluation might be helpful.
Early Bloomers (Precocious Puberty)
Definition: Puberty beginning before age 8 in girls
Characteristics:
- Initially taller than peers
- Growth spurt occurs earlier
- First period may come as early as age 9-10
- Growth plates close earlier
Final Height Impact:
- May end up shorter than genetic potential
- Less time for pre-pubertal growth
- Medical treatment sometimes considered
Late Bloomers (Delayed Puberty)
Definition: No breast development by age 13 or no period by age 15
Characteristics:
- Initially shorter than peers
- Growth spurt occurs later
- First period may come at age 14-16
- Growth plates remain open longer
Final Height Impact:
- Often "catch up" to peers in height
- More time for childhood growth
- Usually reach genetic potential
The Catch-Up Phenomenon
Research shows that early and late developers tend to reach similar final heights if their puberty timing falls within the normal range. A girl who develops early may be the tallest in her class at age 11 but average height by age 16. Conversely, a late developer might be the shortest at 13 but catch up by 17. This is why comparing your daughter to her peers at any single point in time can be misleading.
When Early Puberty Becomes a Concern
While some variation in puberty timing is normal, true precocious puberty (before age 8) should be evaluated by a pediatric endocrinologist. Concerns include:
- *Breast development before age 7-8: May indicate hormonal issues requiring investigation
- *Rapid progression: Going through puberty in less than 2 years
- *Significant height compromise: Bone age significantly advanced beyond chronological age
- *Psychological impact: Emotional difficulties coping with early physical changes
Growth Expectations After First Period
One of the most common questions parents ask is: "How much will my daughter grow after her first period?" While individual variation exists, research provides fairly consistent answers.
What the Research Shows
Average Post-Menarchal Growth
Studies show that girls grow an average of 2-3 inches (5-7.5 cm) after their first period. Most of this growth occurs in the first year after menarche.
Year-by-Year Breakdown
First year after period: 1-1.5 inches. Second year: 0.5-1 inch. Third year: 0-0.5 inches. After three years: minimal to no growth.
Individual Variation
Some girls grow as little as 1 inch total after menarche, while others may grow up to 4 inches. Earlier menarche generally means more remaining growth.
Spinal Growth
Some of the post-menarchal growth comes from the spine, not just long bones. Spinal growth can continue slightly longer than leg growth.
Practical Calculation
A useful rule of thumb: At the time of first period, add approximately 2 inches to your daughter's current height to estimate her final adult height. For example, if she's 5'2" at menarche, she'll likely be around 5'4" as an adult. This is an approximation, and individual results vary based on bone age and genetic factors.
Factors That Affect Final Height
While genetics plays the dominant role in determining adult height, several other factors influence how close a girl comes to her genetic potential.
Genetics (60-80%)
Parental heights are the strongest predictor. The mid-parental height formula provides a good estimate: (Mother's height + Father's height - 5") / 2 for girls.
Nutrition
Adequate calories, protein, calcium, vitamin D, and zinc are essential. Malnutrition can prevent reaching genetic potential. However, excess nutrition won't make a child taller than genetics allow.
Sleep
Growth hormone is primarily released during deep sleep. Chronic sleep deprivation can impair growth. Teens need 8-10 hours of sleep per night.
Physical Activity
Regular exercise supports healthy bone development. However, extreme training (elite gymnastics, ballet) during puberty may delay growth if energy intake is insufficient.
Health Conditions
Chronic conditions like celiac disease, inflammatory bowel disease, or untreated thyroid disorders can affect growth. Growth hormone deficiency is rare but treatable.
Hormonal Factors
Growth hormone, thyroid hormone, and sex hormones all play roles. Imbalances can affect both the timing of puberty and final height.
When to See a Doctor About Growth Concerns
While there's wide variation in normal growth patterns, certain signs suggest a medical evaluation may be warranted. A pediatric endocrinologist specializes in growth and development concerns.
Red Flags Requiring Evaluation
Very Early Puberty
Breast development before age 8, pubic hair before age 8, or menstruation before age 10
Very Delayed Puberty
No breast development by age 13, no period by age 15, or more than 5 years between breast development and first period
Growth Failure
Height below the 3rd percentile, dropping across percentile lines, or growing less than 2 inches per year before puberty
Height Significantly Different from Parents
If predicted adult height is much shorter than expected based on parental heights
Rapid Growth Concerns
Growth significantly faster than normal for age, especially before typical puberty age
What to Expect at a Growth Evaluation
- 1.Medical history: Including family heights, growth patterns, and pubertal timing
- 2.Physical examination: Assessment of current height, weight, and pubertal stage (Tanner staging)
- 3.Bone age X-ray: A left hand/wrist X-ray to assess skeletal maturity and remaining growth potential
- 4.Blood tests: May include growth hormone, thyroid function, and other hormone levels
- 5.Growth prediction: Estimated final adult height based on bone age and current measurements
Reassurance for Most Families
Most growth concerns turn out to be normal variations. Constitutional delay (being a "late bloomer") and familial short stature (having shorter parents) are the most common explanations for children who seem short compared to peers. Both are variations of normal, not medical conditions requiring treatment.
Predicting Your Daughter's Adult Height
While no method can predict adult height with perfect accuracy, several approaches can give you a reasonable estimate.
Mid-Parental Height Formula
The most commonly used method. For girls:
Accuracy: Within 4 inches for 95% of children
Double Age 2 Method
A simpler but less accurate method:
Accuracy: Rough estimate only; many factors affect growth after age 2
Bone Age Method (Most Accurate)
Performed by a doctor using X-ray and growth tables:
Accuracy: Within 1-2 inches for most children when performed near puberty
