Calculate how tall your baby will grow

Author GreatDad Writers
Submitted 20-04-2007

Children pass through different stages of rapid growth throughout their childhood. While no two babies will show the same rate of growth, it is important to remember that height is a combination of several factors including genetics, nutrition, health, gender, etc.


Knowing how tall your baby grows may be useful for the following reasons:

  • Every year, you have to contend with clothes that no longer fit or are of an incorrect size. Knowing the child’s height may be useful in planning clothes, bed size, etc.

  • Some children may grow too fast or too slow. In rare cases, certain health conditions may impede or propel growth. A height predictor may help you to identify any deviance, which your doctor can then diagnose.

Here are some simplified methods to calculate your baby’s height:

  • Take the average of the parent’s heights. There is 90% probability that the predicted height will be less or more than this average by usually two inches, but rarely exceeding four inches. The figure is normally more for boys and less for girls.

  • Doubling the height of children when they are two years old gives a figure close to the predicted height at age 8.

  • Tools are available on the Internet that use the child’s height at different intervals to compute a figure based on the growth pattern, gender, and other factors.
