Ever wondered how tall your child might be when they grow up? Our free Height Calculator gives you a quick, science-backed prediction using the mid-parental height formula. Whether you use US or metric units, this tool provides an instant estimate of your child’s future adult height in feet/inches and centimeters.
What Is a Height Calculator?
A Height Calculator is an online tool that uses the parents’ heights and the child’s gender to estimate their likely adult height. It’s based on the mid-parental height method, which is widely used by pediatricians and growth specialists. While it’s not 100% exact, it gives a realistic prediction of your child’s growth potential.
How the Height Calculator Works
Select Units – Choose US Units (ft/in) or Metric (cm).
Enter Mother’s Height – In feet/inches or cm.
Enter Father’s Height – In feet/inches or cm.
Choose Gender – Select “Male” or “Female.”
Calculate – The tool instantly predicts the child’s adult height and displays it in both your chosen unit and the converted unit.
Formula Used:
For Boys: (Mother’s Height + Father’s Height + 5 inches) ÷ 2
For Girls: (Mother’s Height + Father’s Height − 5 inches) ÷ 2
This method adjusts for gender differences and provides a statistically reliable range.

Frequently Asked Questions (FAQs)
1. How accurate is this prediction?
The height calculator is an estimate. Most children will reach an adult height within ±2 inches (±5 cm) of the prediction, but genetics, nutrition, and health factors can cause variation.
2. Can this be used for teenagers?
Yes! Even for teens, the calculator gives a good approximate adult height, though bone age scans can provide more precise results.
3. Does nutrition affect the prediction?
Yes. Proper diet, exercise, and sleep play a big role in helping children reach their genetic growth potential.
4. Will identical twins have identical results?
They may have similar predicted heights, but individual growth can still vary slightly.
5. Can I use it for metric height only?
Yes, simply switch to Metric Units and enter the parents’ heights in centimeters.
