When Do Girls Stop Growing in Height? Full Timeline & Growth Signs

toc

A girl's height typically stops growing around ages 14 to 16, but changes in other parts of the body and in bone density continue for some time.

Primary Growth & Age Milestones

Stage / Question	Key Facts
When do females stop growing	Ages 14–16 (1–2 years after first period)
do females grow after 18	Height: No (growth plates closed). Bone density & body shape: Yes
Signs growth plates are closing in females	Growth slows down, feet/hands stop sizing up, X-rays show solid bone line

Female Growth Timeline

Age Range	Growth Event
8–11 yrs	Puberty onset & initial growth spurt
11–12 yrs	Peak height velocity (fastest growth)
12–13 yrs	Menarche (first period occurs)
14–16 yrs	Epiphyseal fusion (height growth ends)
18–25 yrs	Peak bone mass & pelvic widening

When do females stop growing in height?

A girl's height increases as long as the growth plates located at the ends of her bones remain open. During puberty, hormone levels rise rapidly—first accelerating height growth and then hardening the bones. Normally, 1 to 2 years after a girl gets her first period, the growth plates close completely, after which no further height growth occurs.

Do females grow after 18? 

After age 18, a girl's height generally does not increase because the growth plates have already fused. Claims of increasing height after this age are usually related to posture correction. However, development in other areas of the body continues up to age 25, such as increasing bone strength (bone mass) and changes in body fat distribution.

Signs growth plates are closing in females:

• Minimal height increase over a full year, such as gaining less than 0.5 inches.

• Shoe or foot size stabilizes a few months before growth plate closure.

• Reaching 2 years after the first period indicates growth plates are closing.

• Hand or wrist X-rays show that the cartilage gap between the bones has disappeared (fused).

Frequently Asked Questions

Question	Short Answer
Can exercise increase height after growth plates close?	No. Exercise improves posture, which helps stand fully upright, but does not lengthen fused bones.
Why do some girls stop growing earlier than others?	Early onset of puberty (precocious puberty) causes growth plates to fuse sooner.
Can nutrition boost height during puberty?	Yes. Adequate calcium, vitamin D, and protein help achieve maximum genetic potential before plates close.
Does sleeping more make females grow taller?	Human Growth Hormone (HGH) peaks during deep sleep, supporting natural growth while plates are open.
How can a doctor check if growth plates are still open?	A standard hand or wrist X-ray reveals whether cartilage remains open or fully calcified.
