(2) Try this: Girls are half of their adult height at 18 months of age, while boys are half of their adult height at 24 months of age.
Did you know the earliest growth spurt, from baby to toddler, actually accounts for roughly half of a child's adult height? A simple method to predict adult height is to double the child's height at age 2.
Doubling a child's height at age 2 can provide an estimate of how tall that child will be in adulthood. (Boys are usually a little taller than that number and girls a little shorter.) That's because by 2 most children have reached the growth chart percentile they will stay on as they grow.
After the growth spurt during puberty, which differs slightly for girls and boys, neither will typically grow much more, and girls typically stop growing by 15, while boys stop at around 18 years of age. That being said, there are environmental factors that can affect the height of a child.
According to the U.S. Food and Drug Administration, short stature means an estimated final height below 5 feet 3 inches for boys or 4 feet 11 inches for girls.
How Tall Should a 12-Year-Old Be? We can only speak to national average heights here in North America, whereby a 12-year-old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12-year-old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).
What is the average height of a 14-year-old boy? The average 14-year-old boy measures 66.7 inches, or 5 feet 7 inches. 14-year-old males in the 5th percentile of the average measure 5 feet tall.
Though it's probable that your real height is close to your predicted height, this isn't always the case. It's entirely possible for two short parents to have a tall child, and vice versa. It's just more likely that the child of short people will end up vertically challenged.
That is, for boys you can explain about 64 percent of the variation in adult height by knowing height at age 4. This is a reasonably strong correlation, and means that kids who are tall when they're 4 will likely be tall as adults.
Long babies may well grow up to be tall, but genes also have an influence. If you and your partner are tall, then your baby is also likely to be tall, even if he was a small baby. However, there are no guarantees. Some children grow up to be shorter adults than their parents, and others taller.
What is the average height for a 14 year old? The average height for a 14-year-old boy is 162.4 cm (5 ft 3), while for girls, it is 159.8 cm (5 ft 2). Expect a significant variation in height at this age. However, some people will have finished puberty, while some may not have started yet.
We find that firstborn children are taller than children of higher birth order: The height-for-age gap for third (or higher)-order children is twice the gap for children second in birth order.
Record the genetic father's height. Average the two heights together. Add 2 1/2 inches to that average if you are predicting a boy's height. Subtract 2 1/2 inches to that average if you are predicting a girl's height.
For an exceptionally tall man, his son will be around 4 inches (10cm) shorter than him. His son will still be taller than average. A 58-inch-tall (147cm-tall) man will have a 63.5-inch-tall (161cm-tall) son. For an exceptionally short man, his son will be around 5.5 inches (14cm) taller than him.
Chances are you'll be around the same height as your parents. If one parent is tall and one short, then you're likely to end up somewhere in between. But you could be taller or shorter, too. Boy, there are a lot of "buts" when it comes to height!
Tallness is a recessive trait, short stature is dominant. This means, if two tall people mate they will likely have very tall children. But if a tall person and a short person mate, the short person's short gene will win out over the tall gene (unless the short person has a hidden gene for tallness.)
Study after study has found that taller men and women are generally considered more attractive. Intriguingly, you can even guess someone's height from their face, meaning a mugshot on a dating website is not going to hide a more diminutive frame.
A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.
A study on women's and men's height preferences found that women are most satisfied when their partner was 8 inches (21cm) taller. Men are most satisfied when they are 3 inches (8cm) taller than their partners. Another study found that among men, 13.5 percent prefer to date only women shorter than them.

Typically upto 18. Predicted height is 157cm but may be taller.
That is really quite short. Not unheard of but not common either. You're a almost a foot and a half shorter than the average of 5″4″ fir girls age 17. In the US at least.
For example, if you look at the CDC growth chart for boys 2 to 20 years, a 13-year-old boy who is 5'1" (61 inches tall) is in the 50th percentile. Based on that curve, they should reach an adult height between 5'9" or 5'10" (69–70 inches).
