You may have heard of a growth chart calculator also being called a baby percentile calculator by some health experts or providers.
Growth percentiles are used to compare your baby’s growth to the average growth of babies of the same age and sex. The best way to understand a growth percentile is to imagine 100 babies of the same age and sex. If your baby’s length or height is found to be in the 25th growth percentile, that means that out of the 100 babies, your baby is longer or taller than 25 of the babies but shorter than 75 of the babies.
In a second example, imagine that a baby boy weighs 20 lbs. at 10 months. According to the growth chart calculator, that puts him in the 50th percentile—meaning that 50 percent of 10-month-old babies weigh less and 50 percent weigh more.

If you have any questions about growth or growth percentiles, or about your baby’s weight, height, and head circumference, contact your healthcare provider.
