What is the average height for a 13-year-old?

What is the average height for a 13-year-old? How tall are 13-year-olds? It’s hard to know the average height of 13-year-olds, because it varies depending on many factors, including gender and ethnicity.

In general, though, boys typically grow about 4 inches between the ages of 11 and 14, while girls grow about 3 inches during that same time period. But these numbers aren’t hard and fast rules; they’re just a general guideline to keep in mind when looking at the average height of 13-year-olds.


How tall are kids really?

Now that you know how to measure your kids’ height, how do you compare them to their peers? The answer to that question depends on several factors—their race/ethnicity, gender, and their environment. Children growing up in urban environments tend to be smaller than children growing up in rural environments because of differences in nutrition and exposure to pollutants (such as pesticides).

And while anorexia affects children of all races, African American girls are more likely than any other race or ethnic group (except Native American boys) to enter puberty. If your baby is African American or born prematurely or with a low birth weight, there is also a chance that he may fall into one of these high-risk categories.

Girls vs. Boys

Gender doesn’t affect your final height as much as genes, but there are some definite height-increasing factors to keep in mind. Girls generally have a natural growth spurt earlier than boys, between 8 and 12 years old, which means that any growth hormones they get before then (through various supplements or treatments) may not be as effective.

A rule of thumb for teens is that about four inches are lost per decade after age 16, so girls may end up an inch shorter than average and boys may end up two inches shorter. The average male in America today stands at 5 feet 9 inches and 140 pounds while female average is 5 feet 4 inches and 120 pounds. This has been increasing in recent years because of increased access to nutrition and healthcare; still people consider it good news.

Top factors influencing growth & development: Both boys and girls should gain about 2 inches of height per year from age 9 to 15. At their peak, girls will be on average 4’10 1⁄2 tall (147 cm) and boys will be on average 5’7 3⁄8 tall (170 cm). In addition to reaching puberty and experiencing healthy physical growth, children in these years are developing intellectually, socially, emotionally, artistically and creatively.

Height Increasing Factors for Kids

From about age 10 to 14, kids’ bones are still growing. At 14 years old, boys are on average 5 feet 2 inches tall and girls are 5 feet 1 inch tall. These averages account for factors like nutrition and genetics, which affect their rate of growth. Height increasing factors include:

  • Healthy eating habits – Proper nutrition can help your child grow at a steady pace throughout childhood.
  • Bone health – Having healthy bones will also help your child reach his or her maximum potential height as an adult.
  • Genetics – A parent’s bone structure may determine how tall their children end up being, though not necessarily how old they get there.
  • Being active – Getting plenty of exercise can also increase your child’s total height by stimulating bone growth.

Final Words!

The average height of an adolescent male aged between 12 and 14 years old is approximately 150.5 cm (4 ft 11 inches). It has been shown that after puberty, males tend to be around 6’1 (1.85 m) in their late twenties to early thirties.

The average height of an adolescent female aged between 12 and 14 years old is approximately 147 cm (4 ft 10 inches). It has been shown that after puberty, females tend to be around 5’7 (1.70 m) in their late twenties to early thirties. The results were measured by taking thousands of surveys conducted on representative sample groups in countries across the world during the 1990s, so it’s not only a reference point but very accurate!
