When Do Girls Stop Growing in Height?

Growing, Growing, Done: Girls and Height

Will she continue to be your little girl forever, or will she eventually tower over you? And just how many more times will you have to replace her jeans with longer pairs? Most girls reach adult height by the age of 15. But, like with all things involving the human body, some variation is normal. Your daughter may shoot up to 5'8" at 12 and stay there forever, or she may keep growing until she's ready for college. As long as her doctor isn't concerned about her height, neither should you be.

Normal Height for Girls

Most girls reach their full adult height around the age of 14 or 15, but girls who start puberty later than average may continue growing into their later teens. It's normal for a girl to have a growth spurt a few years before she reaches her adult height. You may notice your daughter seems to shoot up in height when she's around 12 or 13, or around the time that she starts menstruating.

In the U.S., the average height for women is 63.7 inches, or about 5 feet 4 inches. No accurate worldwide height average exists because not all countries can provide reliable data. There is enough data to know which countries have the tallest women, on average. Genetics plays a significant role in determining height, so if your daughter's ancestors hailed primarily from Latvia, the Netherlands, Estonia or one of the other countries on the list of tallest countries (they're primarily Eastern European), she may end up with greater-than-average height.

Estimating Height

If you're picturing her wedding pictures but she's still in diapers, you're in luck. You don't have to wait for your daughter to reach her full height in order to roughly estimate what that number will be. There are two popular and somewhat accurate methods for predicting a child's adult height.

The simpler method requires you to measure her standing height when she's 18 months old. Double that number to get a rough estimate of her adult height. (To estimate a boy's growth, double his height at 2 years old.) The other option is to measure the heights of a girl's parents. Add those heights together, divide them by two and subtract 2 1/2 inches from that number.

These methods aren't scientific and won't prove accurate in all cases because a child's adult height is determined by many factors. Her nutrition and any medical conditions she develops or medications she takes can play a role.

Causes for Concern

As long as your daughter sees her pediatrician at least once a year, you shouldn't worry too much about monitoring her height at home. Her doctor should plot her growth on a chart so he can evaluate her development year-to-year and determine whether she's falling too far behind her peers.

But if you're worried about her growth, you can tell a lot about how healthy she is just by watching her development. A girl who's growing normally should start puberty by the age of around 13. A girl who has started puberty will usually develop curves at the breasts and hips, start menstruating and develop occasional acne. Some perfectly healthy girls start puberty later, but mention your concerns to the pediatrician if your daughter hasn't undergone any physical changes by the age of 14 or so.
