Height Calculator

Height Calculator:

This height calculator predicts your child’s future adult height using scientifically proven methods. For children over 4 years old, it has the Khamis-Roche method, a scientifically proven approach for accurate predictions.

If your child is under 4 years old, you can still estimate their future height using the Mid-Parental Height Method, which considers parental height for height estimations.

How Tall Will I Be?

It's impossible to predict a child's exact adult height, but scientific methods can estimate it. Height is a biological phenomenon that is dependent on several factors like age, health, activity, gender, nutrition, maternal health during pregnancy, and parental genetics. etc. While environmental factors like diet, exercise, and maternal health contribute roughly 20-40% to a child's height, genetics plays the most significant role, accounting for 60-80%.

Newborn babies grow faster from birth till 2nd birthday. After that, the growth slows down. But during puberty (typically around 13 or 14 years), the height again starts to increase at a high pace. Generally, the biological process continues till the age of 15 years (For Girls) and 18 years (For Boys).

Height depends upon the genetics of parents. Therefore, it's not possible to provide a 100 % accurate prediction about the height of a baby. But some scientifically proven methods, such as the Khamis-Roche and Mid-Parental Height methods, are available that provide a good prediction of a child’s future height. Our child height calculator employs these methods to provide reliable results.

How To Predict Height?

There is no method to predict the exact height of a child. However, several formulas have been optimized that help you better estimate the results. Every child has a different growth rate. Where one gains height very rapidly, the other of the same age might not.

1. Khamis Roche Method:

This is one of the most accurate methods for predicting the future adult height of the child. If your child is 4 years old or above, this method is best to predict his/her adult height.

Margin of Error:

For Boys – 2.5 in (6.35 cm)
For Girls – 1.7 in (4.318 cm)

2. Mid-Parental Child Height Method:

If the heights of parents are known, you can predict the child’s height by using the following equations:

Mid-Parental Height = (Mother’s Height + Father’s Height)/2
Girl’s Future Height = Mid-Parental Height – 13 cm
Boy’s Future Height = Mid-Parental Height + 13 cm

This method is most accurate when both parents are of average height.

3. Bone Age - Skeletal Maturity Method:

This method also estimates the future height of any child. In this method, an X-ray of the child’s left hand, wrist, and fingers is taken. Afterwards, it is compared with the Greulich-Pyle Atlas, which is a set of standard bone images.

Three factors are used:

The bone age
The current measured height of the child
Data in Atlas

Considering these parameters, the remaining growth is analyzed at the present bone age, which gives a child’s height prediction more precisely.

Medical experts use the bone age method to check how well or poorly the child’s skeleton is growing. It helps them to analyze certain factors that might contribute to the increase or decrease of skeletal growth. It is considered the most accurate method for predicting the future adult height. This method requires getting help from a medical professional.

4. Using Growth Charts:

CDC growth charts have been prepared for the children of the United States of America. This method uses 16 charts to help predict a child's future height. Generally, growth charts are used to track the growth of a child over time and help to compare it with the average growth of children of the same age and gender. This way, they allow you to track potential growth problems.

Children's growth follows a curve with periods of rapid and slower growth. CDC growth charts display growth curves, they are primarily used to track growth patterns and identify potential issues. They provide only an estimated range for adult height.

Note: These methods just provide estimations, and individual results may vary.

When Do Boys & Girls Stop Growing?

The growth pattern is not the same for all individuals, but some general trends can be considered:

Boys:

In boys, the growth spurt begins later than in girls, and it continues for a longer period. Boys typically stop growing between the ages of 16 and 18, although some may continue growing till their 20s.

The growth of facial hair is complete and stable
Voice has fully deepened and stabilized
Muscle development reaches adult proportions
No change in the height for a year or more
X-ray indicates complete fusion of growth plates

Girls:

In girls, the most rapid growth is seen during puberty. It begins earlier than the boys. Therefore, most girls reach their maximum height in their mid-teens, but some may continue growing slowly till their late teens.

Girls typically stop growing when they reach skeletal maturity, between the ages of 14 and 16. There are several signs of this, including:

Hair growth is complete and stable
Menstrual cycles are regular and established
No noticeable height increase for a year or more
X-ray shows complete fusion of growth plates

The CDC growth chart below gives a clear picture of the growth cycle of boys & girls with respect to increasing age.

How To Get Taller?

There is no magic pill that could increase your height if you are shorter. Height is not something that anyone can control, but you can contribute to increasing your height or getting taller. Below, we have mentioned some tips that primarily support optimal growth during development.

Tips:

Nutritious Diet: Have a diet rich in calcium, vitamin D, and protein, which are essential for bone development. You must include fruits, vegetables, whole grains, and lean proteins in your diet plan. Limit the consumption of processed foods and sugary drinks
Proper Posture: Maintaining a good posture is very important to support your height and spinal health
Regular Physical Activity: Perform regular exercises that support bone health
Adequate Sleep: Having proper and complete sleep is also necessary for your height as growth hormone is primarily released during sleep

FAQs:

How Tall Will I Be at 14?

Boys: The average height for a 14-year-old boy is approximately 162.4 cm (5 feet 4 inches)
Girls: The average height for a 14-year-old girl is approximately 159.8 cm (5 feet 3 inches)

Note: It's important to remember that these are average heights, and individual growth rates may vary significantly.

Can Identical Twins Be of Different Heights?

Absolutely Yes! Even though identical twins share the same genetic code, they can have different heights. If one child eats a healthy diet as compared to the other one, he/she will be taller than the other one.

Does Height Come From Mother or Father?

You inherit approximately half of your genes from your mother and half from your father, meaning both parents contribute to your potential height.

If both parents are tall, the child is likely to have a tall height
If one parent is tall and one is short, then the height of the child may fall in a range shorter or taller than the average of the parents' heights

Keep in mind that genetics is not the only factor. Some other factors like nutrition, hormones, and overall health play an important role in determining the future adult height of a child.
