The height calculator will estimate your height and let you know how tall your child will be when grows into an adult. You can get height measurements in multiple alternative units as well. The tool uses a couple of scientifically proven methods to predict the maximum future height of your unborn baby.

Height is a genetic process and you can only estimate it. This is because it depends upon the DNA combinations of your parents and perfect calculations in this case are not guaranteed. But our height calculator uses a couple of methods to predict your future height which includes:

Now if the parentsâ€™ heights are known, you can predict the child’s height by using the equation:

**(Mother’s Height + Father’s Height)/2**

**Girl’s Future Height = Mid-Parental Height – 2Â½ in (or 6.5 cm)**

**Boy’s Future Height = Mid-Parental Height + 2Â½ in (or 6.5 cm)**

This is one of the most accurate methods to calculate child’s height that is above the age of **4** years. The basic formula that is used by the adult height calculator is given as follows:

**Khamis Roche Height = Child Weight + (Mother Height + Father Height)/2**

- For boys – 2.5 inches
- For girls – 1.7 inches

Most boys stop growing at the age of 16. On the other hand, girls usually stop growing when they are 15 or when menstruation starts.

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