## CDC 0-3 Years: Weight For Length Percentile

### Description:

This calculator is based on the United States Center for Disease Control (CDC) infant charts. These charts are intended for babies and toddlers with an age of 0-3 years.

This calculator provides your child's weight percentile based on length. Length should be measured the subject is in the prone or horizontal position. The percentile shows how your child's weight compares to other children of the same length. The percentile tells you what percentage of children weigh less than your child. For example out of a sample of 100 children, a percentile value of 40 percent means your child weighs more than 40 children and weighs less than the other 60 children.

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