How to Use the Height Predictor Calculator

This guide provides you with a detailed step-by-step process on how to use the Height Predictor Calculator effectively. Follow these instructions to input the necessary data and understand the output results.

Step 1: Input Child’s Gender

The first step is to select the child’s gender. It is a mandatory field and the options available are:

• Male
• Female

Please select the appropriate gender to proceed.

Step 2: Enter Father’s Height

In the next field, you are required to enter the father’s height in centimeters. The input should be within the valid range of 130 cm to 230 cm. Enter the value following the precision allowed by the step of 0.1 cm.

Step 3: Enter Mother’s Height

Similarly, input the mother’s height in centimeters. This is also a required field with a valid range of 130 cm to 230 cm, and a precision step of 0.1 cm.

Step 4: Input Child’s Current Age

Next, input the child’s current age. The age must be within the range of 2 to 18 years, with a step of 0.5 years. Ensure that the age falls within this range to obtain accurate predictions.

Step 5: Input Child’s Current Height

Enter the current height of the child in centimeters. The valid range for this field is 50 cm to 200 cm and must be entered with a precision of 0.1 cm. This is a crucial input for calculating the predicted adult height.

Understanding the Results

• Mid-Parental Height: This value is calculated based on the average height of the parents, adjusted slightly for the child’s gender. It provides a general benchmark of expected height and uses the formula specific to the gender:
  • For males: ((Father’s Height + Mother’s Height + 13) / 2)
  • For females: ((Father’s Height + Mother’s Height – 13) / 2)
• Expected Adult Height Range: This provides a range around the mid-parental height, showing the variance of ± 8.5 cm, giving an insight into the minimum and maximum expected adult height.
• Predicted Adult Height: Based on the child’s current height and gender-specific growth multipliers, this result predicts the adult height of the child. The multiplier differs for males and females, ensuring more accuracy in the prediction.
• Height Percentile: This percentage compares the predicted adult height with the mid-parental height, indicating how the child’s projected growth compares to genetic expectations.

By carefully following each step and entering accurate data, you can effectively use the Height Predictor Calculator to estimate your child’s future height. Be sure to review and correct any entries that fall outside the specified ranges for optimal results.
