What is BabyPercentile?
BabyPercentile is a free growth chart calculator for babies and toddlers ages 0 to 5. It helps parents check weight, length or height, head circumference, and weight-for-length or height using WHO and CDC charts. You can enter a birth date and measurements, or use age in months, and see the percentile update right away. It also includes a private growth log that stays only in your browser, so you can track changes over time without creating an account. The tool explains how to read the charts, handles preterm correction, and lets you switch between WHO and CDC references. It’s built to be practical, private, and easy to use at home.
