Can the Baby Growth Percentile Calculator predict my baby's future height or weight?

No, the calculator provides current percentile rankings based on age and gender using CDC reference data. It does not forecast future growth trajectories or predict adult size.

Is the percentile result a measure of whether my baby is healthy?

Percentile rankings show how your baby's measurements compare to a reference population. The tool explicitly states results are not a prescription for health or nutrition, and a doctor should be consulted for health concerns.

Do I need to convert my baby's measurements to specific units before using the calculator?

No, the calculator supports common unit systems, allowing you to enter weight in pounds, kilograms, or stones, and length or head circumference in inches or centimeters.

What do the interpretation notes mean when the tool says results are 'not a prescription'?

The interpretation text clarifies that the percentile calculations are based on CDC growth chart data for reference purposes only and should not be used to make changes to your child's diet or nutrition without consulting a healthcare professional.
