How tall will my child be?



A common question we are asked is how tall is a child going to be. Many people hear about a formula where you double the height of a child at 2 years of age to get their final adult height. I tell people that based on that formula, I should be 6 feet tall, and I am still waiting for my last growth spurt!

There is a better “guess” for end adult height for children. This is based on a formula from Dr. John R. Welsey. I have told many people about this and decided the best way to get this to everybody was to post it on-line.



Boys- height in centimeters at 3 years multiplied by 1.29 plus 54.9 cm. Adult height = Ht (cm) x 1.29 + 54.9 (cm)

Girls- height in centimeters at 3 years multiplied by 1.29 plus 42.3 cm. Adult height = Ht (cm) x 1.29 + 42.3 (cm)


Enjoy, but realize that I still have a few inches to grow to get to my final adult height based on this formula, too!
