Description:

Note, the CDC recommends the use of the WHO charts for babies and infants from birth to two years of age. This app uses WHO tables and data for calculations.

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

A percentile of 50% represents the average or mean weight. A value below 50 percent means a baby weighs less than the average. A value greater than 50 percent means a baby is above average. This does not mean your baby is overweight or underweight. A doctor or physician should be consulted to determine weight status.
