About
Height is determined 70% by genetics and 30% by environmental factors like nutrition, health, and exercise. There are many other variables, so the science of height prediction is not 100% accurate. However, there are two methods that can give you a good estimate as listed below. This app implements both the Mid-parent method and the more accurate Khamis-Roche method. Tracking your child's height with this app can show you if your child is developing normally. • Mid-parent Method This method can be used if your child is less than 4 years old. Derived from a 1948 article by Horace Gray in the journal of Child Development, it is still widely used today. The margin of error is +/- 4 inches or 10.16 cm. This is a simple formula where the adult the adult height is calculated from the parents' height and the child's gender. • Khamis-Roche Method This method can be used for children 4 to 17 years old. Developed by Dr. Khamis and Dr. Roche, this method is around 90% accurate. It uses the child's age, gender, height, weight, parents' height along with some scaling factors and equations to predict the child's adult height. • Bone-Age Method The Bone-Age method is more accurate than the Kkamis-Roche method, but it requires that an X-ray of the hand. Obviously, Adult Height Calculator cannot take X-rays! Maybe a future version of our smart phones can :)

- Bug fixes and improvements By the way, as the sole developer of the app, App Store reviews are very helpful for me. If you think Baby Growth Chart Percentile is worthy, would you mind taking a moment to write a review? I'd greatly appreciate it. :)
