1. What is Mid Parental Height?

Mid Parental Height (MPH) is an estimate of a child's adult height based on the heights of the biological parents. It provides a rough prediction of how tall a child might grow, though individual variations can occur.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• Father's Height — Biological father's height in centimeters
• Mother's Height — Biological mother's height in centimeters
• 13 cm — Adjustment factor accounting for average height difference between genders

Explanation: The formula accounts for genetic potential by averaging parental heights with a gender-specific adjustment.

3. Importance of Height Prediction

Details: Mid parental height helps assess whether a child's growth is following their genetic potential and can be useful in evaluating growth disorders.

4. Using the Calculator

Tips: Enter both parents' heights in centimeters and select the child's gender. The result is an estimate with a range of ±10 cm in most cases.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this prediction?
A: The MPH gives a rough estimate, with most children falling within ±10 cm of the predicted height. Many factors influence final height.

Q2: Does this work for all ethnic groups?
A: The formula works best for populations with similar genetic backgrounds to the parents. Local growth charts may provide more accurate references.

Q3: What if parents are very tall or short?
A: The prediction may be less accurate for extreme parental heights due to regression toward the mean.

Q4: Can nutrition affect the result?
A: Yes, adequate nutrition is required to reach genetic height potential. Poor nutrition may result in shorter adult height.

Q5: When should I be concerned about my child's growth?
A: If your child's height is significantly below the predicted range or growth velocity is abnormal, consult a pediatrician.
