What is the 75th percentile?

How do you read a child’s growth chart percentile?
If a child’s weight is at the 50th percentile line, that means that out of 100 normal children her age, 50 will be bigger than she is and 50 smaller.

What is my child’s growth percentile?
The percentile number means that your child exceeds that percentage of children their age for that measurement. If your child is in the 75th percentile for height, they are taller than 75% of other kids her age.

Written as a formula it look like this: With an increase of p% the growth factor is. g = 100 + p100 or shorter: g = 1 + p100. Vice versa, the growth factor g gives a percentage increase of p = 100(g – 1).
