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.
There are several factors that can impact the height of a baby or a child including both parents' height, your family tree and genetics, and environmental factors. We look at how genetics affect how tall (or how short) children grow up to be.
It is believed that height of a child depends upon the genes inherited from parents. However, it is often seen that tall parents may have short children and vice-versa.
However, several formulas can provide a reasonable guess for child growth. Here's a popular example: Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls.
Ninety percent of kids will fall in plus or minus two inches of their mid-parental height. So, if the parents are both short, it may be normal for the child to be short. It's more concerning if the parents are tall, but the child is growing short.
How to predict how tall a child will be. According to Johns Hopkins Medicine, people may wish to try the following formula for predicting how tall a child will be: Measure the height of both biological parents. For male children, add 5 inches (in) to the father's height, add the mother's height, then divide by 2.
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!
For most individuals, though, height is controlled largely by a combination of genetic variants that each have more modest effects on height, plus a smaller contribution from environmental factors (such as nutrition).
What can I do to become taller? Taking good care of yourself — eating well, exercising regularly, and getting plenty of rest — is the best way to stay healthy and help your body reach its natural potential. There's no magic pill for increasing height.
Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Menstruation has started within the last one to two years for girls. Other signs that you may have stopped growing include slowed development over the last one to two years, completion of pubic and underarm hair growth, stable shoe size, and for girls, the onset of menstruation within the last one to two years ( 12 ).
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).
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!
How tall will I be? I'm a 13 year old girl and already 5'8. It depends on your parents height, but if at least one of them are tall (over 5′7″ for mom, over 6′0″ for dad), then you'd likely be at least 5′10″ or 5′11″ by the time you stop growing around age 15 or 16.
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.
The simplest way to conclude if you're tall or not is to look around you. If you're in the US, compare your own height to the North American average for men, which is 5'9″ (177 cm). If you are 5'10” (178 cm) or taller, you are considered taller than average in North America.
Your height is mainly dictated by genetics, however there are some things you can't blame your parents for. While your final height is dictated chiefly by the genes you inherit from your parents, factors like nutrition and disease account for around 20 per cent of the height variation between people.
If you are a man with average height, you can expect your son to be a few inches (centimeters) taller than you. This is because the regression line and the SD line both coincide at the average heights. For instance, a father with an average height of 67.7 inches (172cm) will have a 68.7-inch-tall (175cm-tall) son.
Do humans get taller every generation? That was happening for a while, but stopped around 1960: The genes that determine height do not really change over time. However, malnutrition and disease can stunt growth.
