It's a question many parents ask, but there is no magic way to look into the future and see how tall your children will be when they grow up.
You can get a good idea, however, by using a method that can predict your child's future height. There are three methods you can use to estimate how tall your child will be in adulthood. While none of the methods is perfect, any will be able to give you some idea of how tall your kids might be when they grow up.
You can even use all three methods and see how they compare. More importantly, these are helpful tools your pediatrician can use to spot when your kids aren't growing well. For example, if your child has the genetic potential to be 6 feet 2 inches, but is following a growth curve that will put him at 5 feet 6 inches, your doctor may want to investigate a possible cause for this. Many factors can influence your children's future growth, including their overall health and nutritional status as well as their genetic potential.
The "two years times two" method for predicting your child's future height is as easy as it sounds. The drawback is that you need to wait until they are two years old or find the measurements you took then.
This method has been used for a long time, though no research is available to back up its accuracy. It is valid for children above the age of four. The publication by Dr. Harry Khamis and Dr. Alex Roche was called Predicting adult stature without using skeletal age: the Khamis-Roche method.
It's the most accurate method of child height prediction without determining the skeletal age. For boys, the margin of error is 2. Please note that this future child height calculator was developed by research on a group of Caucasian children so it may be less accurate for kids of other ethnicities. The mid-parental formula is the easiest way to calculate a child's height based on parents height. Here is how it works:. You can expect a margin of error of about four inches either way. You can convert metric to imperial length units using our length calculator.
As we have already discussed, a child's height is primarily determined by genetics. However, it does not depend solely on the parents height. It's inherited in a way so that children may be taller or shorter than their parents since height inheritance is polygenic - the answer to how tall your child will be is scattered among many genes. The maturity of a child's skeletal system might be estimated by using a bone age study. It consists of taking a single X-ray of the left wrist, hand, and fingers.
It is a painless procedure that exposes the individual to a very small amount of radiation. Afterwards, the image is compared to standard images from a bone development atlas, where the references were made on large studies of kids.
Bone age is measured in years. The growth of bones is possible thanks to a particular area within two ends of long bones - the growth plate. This is a hyaline cartilage plate, which consists of actively growing cells. These plates can be found in children's bones, and, in adolescents, they turn into an epiphysial line the residue of growth plate.
This replacement is called epiphysial closure or growth plate fusion. The fusions complete in age for girls and for boys. Growth plates are easy to identify on an X-ray because they are softer and contain less minerals than standard bone.
That makes them appear darker than the rest of the skeleton on the X-ray image. They look different at each age - thanks to that, a doctor can determine the bone maturity by simply reviewing its appearance. Then, the image is compared with the closest matching image from an atlas. Observing a difference between a child's bone age and their chronological age may point to a growth problem, but it is not the rule.
Some kids with perfect health can have a disparity in skeletal and chronological age. The control of bone age is done to assess the tempo of the maturing process of a child's skeleton. This allows doctors to diagnose conditions that delay or accelerate physical growth. Using the skeletal age, physicians may predict:.
The study is also used to monitor the treatment process of kids with growth deficiencies. There are plenty of factors that may affect growth:. Gilsanz, O. Ratib by Springer.
Standardized growth charts are an essential tool used by doctors to determine whether a child is growing as expected. They are based on regular measurements of a child's height, weight, head size, and BMI.
You can check them here. They are also helpful for judging the onset of puberty in an older child. Growth process differs between girls and boys. Female growth is fast in childhood, and when they reach puberty, it speeds up rapidly. They achieve adult height usually at the age of , or a couple of years after menstruation occurs the first time. Following the growth charts from CDC, the average height of adult woman at age 20 is in cm. In the table below, you can find a few other numbers for different ages.
Boys come into puberty later than girls. It is believed that in adulthood a male child will be double the height he was at 24 months. A girl will grow to be double of the height she was at 18 months.
This is only an approximate calculation and not an accurate prediction. Another way to predict height is to take the average height of the parents and then, for boys add 2. Nutritious food is an important determinant for the final height of a child. A child that is well-nourished and active is likely to be taller than a child on a poor diet. Eggs are a good source of protein. Studies in developing countries have shown that children who are regularly fed with at least one egg a day are taller than children who do not get this daily nutrition.
In developing countries it has been estimated that poor nutrition and hygiene cause an estimated million children under age five to have stunted growth. There is no evidence that activities like hanging, climbing or swimming can increase height. Post a Comment Comments should be on the topic and should not be abusive.

Lolll, India. That is, rather than just relying on how old the child is, they also incorporate information from X-rays to mark skeletal growth. The more developed the skeleton, the less future growth is expected. The chart shows the correlation between child height at various ages and adult height. At birth, the correlation between birth height or length and adult height is about 0. This is a fairly weak correlation.
By age 4, the correlation is about 0. That is, for boys you can explain about 64 percent of the variation in adult height by knowing height at age 4. Imagine, for example, that you have a 4-year-old boy who is 3 feet 9 inches tall.
