How tall should a 12-year-old be?

When you have a child, it’s natural to be concerned about a variety of things, and for most parents, growth expectancy is near the top of the list. Puberty occurs at varied dates for boys and girls, ranging from 8 to 14 years old.

As a result, both girls and boys will grow in height throughout this time. The elements that influence a child’s growth differ, with heredity playing a big role. Nutrition and overall health will also have an impact, but not as much as genetics.

Then there’s puberty, which will catch you off guard for a while. Hence, you should pay attention to your child when he or she reaches the age of twelve, which is a common age for puberty and growth.

The average height of a 12-year-old

The typical height of a twelve-year-old is determined by a variety of factors, including genetics, puberty, and wellness.

The average height of 12-year-old boys

The average height of 12-year-old teen boys (according to the 50th percentile) is roughly 58.7 inches (or 149 centimeters).

Your 12-year-height is influenced by a variety of things. This page will inform you of the average height of 12-year-olds, as well as other relevant information.

For example, during puberty, which occurs between the ages of 8 and 14, both girls and boys will experience distinct height changes.

Girls typically begin puberty between the ages of 8 and 13, whereas most boys begin puberty between the ages of 10 and 14. As a result, because girls reach puberty earlier than boys, they are taller at the same age (source).

The average height of 12-year-old girls

Teenage girls, on the other hand, are usually 0.7 inches taller than teen boys (on average). In particular, a 12-year-old teen girl’s average height is approximately 59.4 inches (151 centimeters). This average height chart for an 11-year-old girl might be used as a guide.

This is based on all girls in this age group’s 50th percentile. In addition, the average height chart for teen girls is more detailed than that for boys.

Girls, on the other hand, are typically 0.7 inches (on average) taller than boys at this age due to the fact that they reach puberty earlier.

Boys, on the other hand, are still developing when they reach puberty and are more likely to grow faster than they were before their growth spurt began.

How to predict a child’s height based on their age

Although every parent and doctor will try to forecast a child’s height at any age using averages and clinical growth charts, it is extremely difficult to anticipate a child’s height at any age.

Parents’ heights are the best predictors of a child’s height, yet no formula can be 100% accurate. Despite this, many doctors and laypeople alike utilize a popular method to estimate a child’s height expectancy.

Depending on the system you use, you sum the heights of the two parents in inches or centimeters. For boys, add five inches or thirteen centimeters, and for girls, subtract five inches or thirteen centimeters.

When you divide this number by two, you should get a general height predictor for any child.

Consider having two parents who are both 5 feet and 9 inches tall. That’s 69 inches tall multiplied by two, for a total of 138 inches. That’s 175 centimeters apiece, for a total of 350 centimeters.

When you divide 175 centimeters by two, you get 175 centimeters. Their daughter’s expected height is 64 inches (162 centimeters), and their son’s expected height is 74 inches (188 centimeters), or 6 feet and two inches.

By the age of 18, children are thought to have reached their maximum height, however, some continue to grow after that. Most growth charts predict that between the ages of 12 and 18, a teen will grow four to six inches.

At the age of 12, the hypothetical child would be between 5 feet 8 inches and 5 feet 10 inches tall, which is possible.

We can’t accurately estimate the height, but we can provide averages. This and other formulas, when used with growth charts, can help determine typical heights at various ages.

The typical height of a 12-year-old

The terms “typical heights” and “average heights” are not interchangeable. A usual height is what you’d expect, and we get this information from growth charts. The average height of a group is the sum of its members’ heights.

According to the CDC’s (Center for Disease Control and Prevention) standardized growth charts, girls will stand between 55 and 64 inches tall by the age of 12, or 4’7″ and 5’4″ tall.

This age group’s typical weight ranges from 68 to 136 pounds. Boys’ development ranges are relatively comparable at 12 years old, using the same growth charts. Boys are typically 4’6″ to 5’3.5″ tall, with a height range of 54 to 63.5 inches.

Boys’ weights range from 66 to 130 pounds.

The importance of understanding puberty

Because puberty is associated with fundamental psychological changes such as cognition, mood, and social interactions, it is a key process.

Puberty is the process of physical changes through which a child’s body matures into an adult body capable of sexual reproduction. Understanding puberty can assist parents and their children bridge the distance between them, and strengthening their relationships.

As a result, it’s critical that parents and adults, in general, understand the significance of puberty.

Is male adolescent development faster than female adolescent development?

Boys and females develop at different rates throughout early childhood and adolescence, as you may or may not realize. In general, boys develop faster than girls during their adolescent years. Furthermore, in the majority of cases, guys are taller than girls.

As a result, most girls and boys have their own growth charts on which they may track their development over time.

In actuality, the percentile ranking of a youngster is less important than his or her consistency. If your child’s score falls below the 50th percentile, their doctor may need to order more testing to figure out what’s wrong.

What Influences a Child’s Development?

Insulin levels, gender and growth hormones, Down syndrome, thyroid disorders caused by a variety of medical diseases, genetic problems, and other factors can all affect teenage growth abnormalities.

Apart from these factors, childhood hunger might stifle a teen’s development. Furthermore, teenagers who are overweight or obese are more likely to have a slower growth rate.


It’s vital to keep in mind that when forecasting height and growth rates, everything is relative. Genetics plays a considerable, if not the most significant, part in this. Wellness is very important, and in many countries, it is the most important element in predicting a twelve-year-height old’s potential.

Taking into account every chart and standardized measure available, a twelve-year-average old’s height will be roughly 4’10 inches tall, or 58 inches, or 147 centimeters tall.
