How accurate is mid parental height?

How do you plot mid parental height on a growth chart?
Calculating the mid-parental centile If not available, use reported heights. Mark their heights on the relevant Mother and Father scales. Join the two points with a line between them. The mid parental centile is where this line crosses the centile line in the middle.

The higher the percentile, the bigger your child is in comparison to others of his gender and age. The lower the percentile, the smaller your child is. Most children would be closer to the 50th percentile. So if your child is above the 97th or below the 3rd percentile, he is part of a very small group of children.
How to calculate mid-parental height and other growth parameters?
This calculation corrects for the opposite gender parents height so that a mid-parental height can be calculated and evaluated on the appropriate gender growth chart. For boys: [paternal height + (maternal height + 5 inches or 13 centimeters)] / 2. For girls: [maternal height + (paternal height – 5 inches or 13 centimeters)] / 2.
