Description:

This app uses tables and data solely based on United States premature babies. Caution should be used on all charts for the twenty-third week for percentiles at or below the 3rd percentile and at or above the 97th percentile. This is due to a low population size. For the twenty-fourth week, the data is skewed to the left for all head circumference data. See the reference below for more information.

This calculator provides your baby's length percentile based on age. The percentile shows how your infant's length compares to other infants. The percentile tells you what percentage of babies who are shorter than your baby. For example out of a sample of 100 babies, a percentile value of 40 percent means your baby is longer than more than 40 babies and shorter than the other 60 babies.

A percentile of 50% represents the average or mean weight. A value below 50 percent means a baby is shorter than average. A value greater than 50 percent means a baby is above average. A doctor or physician should be consulted to determine growth status.
