Birth of a mutant

Holy crap! I get weekly emails from various parenting sites, and one of them had a cool "predict your child's height" calculator. Now I've seen variations on this before where they basically say that if it's a boy, take the parents' avg heights and add an inch, or something like that... but check THIS out!

Height Predictor

Thanks for using our calculator!

Your son will likely be 6 feet, 6 inches tall at age 18.

This prediction is a "best guess" but it's still just that -- a guess. Based on the formula we used,* there's a 58 percent chance your son's full-grown height will be within 1 inch (above or below) of this prediction, an 85 percent chance it will be within 2 inches, and an 96 percent chance it will be within 3 inches.


The fine print:

This method relies on where your son falls on the Centers for Disease Control's growth charts, and it assumes that he'll remain in the same percentile until he reaches his adult height. The accuracy of the prediction varies because some children will fall into different percentiles throughout childhood.
