When Do Girls Stop Growing? Age, Timeline, and What to Expect

Most girls reach their adult height about 2 to 2.5 years after their first period. That window is set by when growth plates fuse, not by age alone.

Girls grow fastest between ages 10–14; most reach adult height by 14–15; growth continues about 2–2.5 years after first period; growth plates fuse around 16.

Here are the essential numbers about female growth, compiled from multiple sources.

When do girls stop growing taller?

What age do most girls grow taller?

Most girls experience the fastest growth between ages 10 and 14, gaining about 2.5–3 inches per year at their peak. After that, growth slows. According to Healthencyclo, most girls reach adult height around age 14 or 15. The first period marks the slowdown, not the end.

When do girls stop growing after period?

Growth does stop — but not immediately. Healthline states that girls typically continue to grow for 1–2 years after menarche, and FamilyEducation gives an estimate of 1–2 years. Some sources, like DrOracle, say 2–4 years, but the most common clinical estimate is about 2–2.5 years. The key is that growth plates in the long bones fuse about that time, stopping further height increase.

“During female puberty, people tend to have a major growth spurt between the ages of 10 and 14. Most will reach their adult height by the time they are 14 or 15.” — Medical News Today

The pattern is consistent: the period is a milestone, not a finish line.

Do girls stop growing when they get their period?

The short answer: no. Periods signal that the fastest growth phase is ending, not that height is finished. iGrow Clinic explains that menarche usually occurs after peak height velocity.Can a girl grow 4 inches after her period?

Rarely. Most girls gain only 2–3 inches total after their first period, according to IncreaseHeightBlog and ScienceInsights. A 4‑inch gain would be unusual and likely require very early puberty or delayed growth plate fusion.

How much more do girls grow after first period?

On average, girls add about 2–3 inches (5–8 cm) after menarche. ScienceInsights notes that girls who start menstruating earlier (e.g., age 10) may gain around 10 cm, while those starting later (e.g., age 15) gain only about 5 cm. But the typical range is 2–3 inches total.

“In general, girls usually stop growing in height at the age of 14 or 15. Girls will stop growing in height just 2–2.5 years after their first menstrual period.” — Vinmec Hospital

The takeaway: growth after menarche is real but limited.

What are 5 signs that you have stopped growing in height for girls?

If you’re wondering whether you’re done growing, look for these signs—each backed by medical observations.

1. No noticeable height change in 12 months. If your height hasn’t budged for a full year, growth has likely stopped. Healthline mentions this as a practical sign.
2. Period started 2+ years ago. The typical growth window after menarche is 2–2.5 years, so if it’s been longer than that, additional height is unlikely.
3. Growth plates closed on hand X‑ray. Medical imaging can confirm if the epiphyseal plates have fused. Druchen explains that fused plates mean no further linear growth.
4. Full adult breast and pubic hair development (Tanner stage 5). Reaching Tanner 5 usually coincides with the end of growth.
5. Same shoe size for 1–2 years. Foot growth typically stops before height, but stability in shoe size suggests overall skeletal maturation.

If you check off most of these, growth has ended.

Will girls grow taller after 16?

For most girls, growth after 16 is minimal. ScienceInsights notes that by age 16, growth plates in nearly all females have fully fused. Healthencyclo states that most girls reach adult height by 14–15. Rare cases of late puberty may allow a little extra, but it’s usually less than an inch.

Do girls grow until 18?

No. The vast majority stop by 16. The idea that girls can grow until 18 is a myth; male growth can continue a bit later, but for females the window closes around 16.

“Most girls stop growing around 12–13. Usually, girls stop growing one to two years after they start their period.” — Reddit user (highly upvoted)

The implication: by 16, any further height is negligible.

Don’t rely on anecdotal claims about growing after 16—check your growth plates with a doctor if you’re unsure.

Is 5’4 short for a girl at 14?

5 feet 4 inches is the average adult height for US women. At 14, a girl of that height is already at the average adult level, so it’s not short — it’s slightly above the 50th percentile for her age. CDC growth charts show that the 50th percentile for 14‑year‑old girls is about 63 inches (5’3″).

Is being 6’3″ at 15 good?

For a girl, 6’3″ at 15 places her in the 99th percentile — very tall. It’s not a medical problem unless associated with other symptoms; it usually just reflects normal variation in growth genetics. Healthline notes that growth patterns vary widely.

Can I grow from 5’6″ to 5’10” at 16?

Unlikely. By 16, most girls’ growth plates are fused or nearly fused. Gaining 4 inches would require exceptional circumstances. Growth after 16 is typically less than 1 inch, if any.

Overall, height concerns are rarely about medical need.

Remember, growth after your period is a slow fade, not a sudden stop. Don’’t expect to double your post‑period gain overnight.

When do boys stop growing compared to girls?

Boys generally stop growing later than girls — around age 16–17, with some continuing until 18–20. This is because boys enter puberty later. ScienceInsights explains that male growth plates fuse later due to later testosterone rise.

When do men stop growing?

Most men stop by age 18–20, though the vast majority of their adult height is reached by 16–17.

When do boys stop growing in height?

Same as above: around 16–17 for the main growth, with small additions possible until early 20s.

So boys have a longer runway, but girls finish earlier. Along with growth, girls notice other body changes like skin issues (how to manage a stye).

Growth Timeline for Girls

• Age 16: Final growth plates fuse, no further height increase – ScienceInsights

Limitations of the Data

While the 2–2.5 year post-menarche window is widely cited, individual variation is large. Some girls grow more, some less. Data on girls who start their period at age 16 are limited, and official studies on growth after age 16 are sparse. ScienceInsights notes that late bloomers may have slightly different timelines, so these estimates are averages, not absolutes.

Frequently Asked Questions

At what age do girls stop growing in height?

Most girls stop growing around ages 14–15, about 2–2.5 years after their first period.

How much can a girl grow after her first period?

Typically 2–3 inches total, though early maturers may gain a bit more.

Can a girl grow taller after 18?

No. By 16, growth plates are fully fused, so no further height increase is possible.

Does having a period stop growth?

No. The first period marks the slowdown, but growth continues for another 1–2.5 years.

What factors affect a girl’s adult height?

Genetics, nutrition, and the timing of puberty have the biggest influence.

Is there any way to increase height after growth plates fuse?

Once growth plates fuse, natural height increase is impossible. Surgery is the only option, but it’s risky and rarely done for cosmetic reasons.

In short, for girls, growth is mostly done by age 14–15, two to two and a half years after menarche. Boys take a few more years. Track your height, but don’t worry about unrealistic gains—genetics and timing are the real drivers.

For girls wondering when they’ll stop growing, the clear answer is: about 2 to 2.5 years after your first period. Past that point, your growth plates have fused and no amount of stretching or nutrition will add inches.
