Girls are believed to grow faster than boys, but their growth also stops before it does in boys. But, many parents wonder when their daughter would stop growing, as the growth rate of the body may vary depending on what phase of puberty the girl is in.
With that being said, this article will answer this common question with a detailed, in-depth insight, as well as cover some of the other common questions about the growth of both girls and boys.
At What Age Do Girls Stop Growing?
First things first, a lot depends on exactly when the girl gets her first period. Experts say that girls have their biggest growth spurt a year or so before their menstruation begins.
And how do you predict at what age do girls get their first period? Well, while it may differ from one girl to another, it primarily comes down to the genetics. Most times, however, it’s found that girls stop growing considerably earlier than boys. The age is usually 11 to 12 years in most girls, though exceptional cases cannot be ruled out.
However, this may leave you a little confused. Sure, you now know it may depend on the girl’s genetics, but still, how do you predict when is she going to get her first period? Now, while it may or may not be predicted very accurately, a good indication is the age at which her mother got her first period. This basically means that if the mother had got her first menstruation early or late, it’s more likely for the daughter to follow suit.
How Long Do Girls Grow?
There are usually a few phases of growth that determine how long a girl grows. The first stage of height growth is during puberty. Girls are believed to go through puberty anytime between the age of 8 to 14. However, most times, it’s around 11 years of age.
The growth of their height during this stage may vary, though the standard is believed to be 3 inches per year.
The second stage is when girls enter the next stage of their puberty. It’s during this stage when a girl’s height peaks. Most girls usually get into this stage when they are around 12 years of age. Their height may grow around 3.2 inches per year during this stage – usually the fastest it could ever grow.
Finally, the last stage of height growth is when a girl gets her first menstruation. She may be around 13 years of age at this point, and may start growing at an average of 2.8 inches per year – growing for another year or two after the first menstruation.
Now, if you’re looking to get a rough estimate of your daughter’s height when she stops growing, you can use a formula that can be reasonably accurate. You simply need to take the father’s height and subtract 5 inches from it, and then add the mother’s height to it. Dividing the result by 2 may give you a rough estimate of the daughter’s height.
What is the Age You Stop Growing?
We have already had a detailed discussion on when do girls stop growing. As noted above, girls may attain their peak height about a year or two after their first menstruation. Girls are believed to grow the most before their first menstruation hits, but they usually don’t stop growing right after that.
They usually grow for another year or two, albeit at a considerably slower rate. In most cases, they reach their adult height by age 14 – 15.
As for boys, things are different. Most of them grow the most when their age is between 12 and 16. They may have as many as 12 inches added to their height during this period.
As a matter of fact, boys usually also tend to gain most weight during this period. This is also the period when boys go through many changes, one of them being getting acne.
However, in most cases, the growth comes to a halt when the boy is around 18 years of age. There seem to be quite a few cases where a guy may continue growing till he is 21, though. Finally, there are also some exceptional cases where a guy would grow till they are 25 years of age.
What Are the Symptoms of Puberty?
Puberty is basically when a girl or boy’s body develops and undergoes many changes as they start to turn into an adult. With that said, let’s take a look at some of the symptoms of puberty in girls.
- One of the first symptoms of puberty in a girl is the growth of breast buds.
- Another initial symptom of puberty is the growth of pubic hair. They are usually more noticeable on a girl’s legs and arms.
After a year or so, girls would enter the next stage of their puberty. During this stage, the symptoms may include:
- Breast buds continuing to grow further.
- Getting the first period (usually happens after a couple years of getting into the puberty period)
- Pubic hair starting to turn coarse and curly
- Hairs starting to show up in other parts of the body as well such as underarms and top lips.
Symptoms after having entered the final stage of puberty – usually about 4 years after it starts:
- Fully developed breast buds.
- Public hair spreading to other parts of the body, too, such as inner thigh.
- Height stops growing
- Genitals, too, attain their full growth.
Let us now take a quick look at the symptoms of puberty in boys:
- The first sign is usually the growing of testicles and reddening and thinning of the scrotum.
- Pubic hair start showing up under the penis.
Later symptoms of puberty:
- Further growth of penis and testicles.
- Breasts may temporarily grow to a certain extent.
- Considerably increased sweating
- Pubic hair starting to turn coarse and curly
Symptoms of the final stage of puberty:
- Genitals are fully developed.
- Growth of facial hair.
- A slower rate of height growth, which may stop completely at the age of 18.
- Attaining maturity at 18 years of age and turning into an adult.
What Age Do Boys Go Through Puberty?
Cutting right to the chase, most boys enter puberty when they are about 12 years of age. However, it’s apparently also completely normal for a boy to go through puberty as early as at 8 years of age, or as late as at 13 or 14 years of age.
Puberty lasts for several years, and ends when the boy has attained full maturity. Depending on when puberty starts in a boy, this may happen anytime when he’s of the age 15 to 18 years.
