## What is Height Predictor Calculator?

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 :)

## Frequently asked questions about Height Predictor Calculator

### What does the Height Predictor Calculator app do?

This app helps you estimate your child's future adult height. It utilizes two scientifically recognized methods: the Mid-parent method for younger children and the Khamis-Roche method for older children. It also allows you to track your child's height to monitor their normal development.

### What are the prediction methods used in the app?

The app implements the Mid-parent method, suitable for children under 4 years old, and the Khamis-Roche method, which is more accurate for children aged 4 to 17. The Khamis-Roche method is approximately 90% accurate.

### Is the height prediction 100% accurate?

No, height prediction is not 100% accurate. While genetics play a significant role, environmental factors like nutrition, health, and exercise also influence height. The app provides good estimates based on scientific methods, but individual results may vary.

### What information is needed to use the prediction methods?

The Mid-parent method requires the parents' heights and the child's gender. The Khamis-Roche method requires the child's age, gender, height, weight, parents' heights, and uses scaling factors and equations for a more precise prediction.

### What are the common use cases for this app?

Parents can use this app to get an idea of their child's potential adult height, which can be helpful for planning and understanding growth patterns. It's also useful for monitoring if a child is growing within the expected range for their age and gender.
