How to predict your child’s height in the future?


Are you eagerly awaiting the arrival of your precious little one, filled with anticipation about their future and wondering just how tall they’ll grow to be? If you’re concerned about your own height or simply curious about what genetic destiny holds for your child, fear not, for there are methods to help you estimate their future stature. These methods can be broadly categorized into two approaches: objective and subjective predictions.

Objective predictions are rooted in a multitude of factors that come into play during pregnancy. These factors encompass the mother’s health, including her nutritional status and the environment she’s exposed to. They also take into account maternal activities and age. All of these elements contribute to the complex equation that shapes a child’s potential height.

But perhaps the most significant determinant of a child’s ultimate height lies within their genes. At the very moment of conception, when a new life begins to form, the chromosomes carrying the father’s DNA join forces with the mother’s to set in motion the blueprint for the child’s growth and stature.

On the other hand, subjective predictions rely heavily on the findings of scientific studies and research conducted by medical institutions. These studies have illuminated the intricacies of childhood growth, shedding light on the factors that influence how tall a child will become as an adult.

Now, let’s delve into the most reputable and well-researched methods for estimating a child’s future height.

Formula to calculate height based on height of father and mother

In 1970, a formula used to determine the height of children when they reached adulthood was published in the New York Times and was considered by many experts to be highly accurate. This formula can be used to estimate your child’s height.



Child’s height is [(Father’s + Mother’s height) + 13 cm] / 2


Child’s height is [(Father’s + Mother’s height) 13 cm] / 2

The data obtained are the average value. So your child may be 5 cm shorter or taller than average.

How to calculate adult height by measuring height at birth

The formula is:


Child’s height in the first year of birth (mm): 0.2949


Height in the first year of birth (mm): 0.3109

The data obtained are the average value. As a result, your child may be 5 cm smaller or taller.


This formula is suitable for full-term infants. The more accurately the baby’s date of birth is measured, the more accurate the results obtained.

Birth weight can help predict an adult’s size.

Calculation based on height at the time of two years of birth

This is the simplest calculation and produces fairly accurate results. To determine the size of your child’s height, simply take the height at which your child turns two years old and multiply by two.

Find out your child’s height when they are three years old

When your child is 3 years old, size can be predicted using the following simple formula:


Son’s height is three years old (x 0.545 + average height of parents in x 0.544 + 37.69 (cm)


Daughter’s height is 3 years old. 3-year-old children 0.545 + average height of parents + 0.544 + 25.63 (cm).

You can also look at your baby’s height at 3rd birthday to predict the height he will reach in the future!

The formula used to calculate the height of an infant is based on the curve method

The “curve” method The “curve” method is another simple method of predicting the height your child can reach as an adult. It is based on the standard growth chart that pediatricians use to monitor a child’s growth.

Children’s growth charts are currently in the process of being updated across the US according to the Centers for Disease Control and Prevention (CDC). There are different charts for men and women to use. You will need to use the charts for both the “Height for age and Weight for age” charts. To determine the child’s height, use this method:

  • Take your child’s height measurement.
  • Draw your growth curve.
  • Continue to track their growth curves to the same percentage and observe what they will do as adults.
  • This is an estimate of the child’s height.

Factors that can support children’s height development

It is important to understand that in addition to genetics, there are other factors that affect the height of an infant as well as a child’s nutrition. To meet nutritional needs, children should eat a variety of foods rich in calcium and protein for bone development.

For example, children 1-3 years old need between 1,000 and 1,300 calories per day. Your child should eat at least 5-6 meals a day and eat the appropriate portion size, i.e. 1/3 of the adult portion consisting of 3 meals and 2 snacks. In addition, to help children increase height effectively, parents need to pay attention to supplement calcium collagen type 2, vitamin D … in the child’s daily diet to support the child to achieve the ideal height.

In addition, mothers should also keep their children away from various dangerous diseases, especially in the first years of life. If your child often suffers from minor illnesses such as gastrointestinal infections… then this can cause nutritional deficiencies that slow down the child’s height growth.

Parents should also pay attention to encourage children to regularly play sports to help children grow in height quickly and effectively because when exercising, the child’s body will produce a lot of growth hormone, thereby stimulating Stimulates children’s bones to grow and helps children to increase their optimal height in a short period of time.
