- Head circumference support for infants and toddlers

What is a growth percentile?
A percentile shows where a child falls compared with children of the same age and sex. Trends over time are usually more useful than one isolated measurement.
How to Use
- Enter sex, birth date or age, and measurement date.
- Enter height and weight.
- Add head circumference for children up to 36 months when available.
- Review percentile results and track changes over time.
Frequently Asked Questions
How often should I measure a child?
Infants are often measured monthly. Ages 1-3 can be checked every 2-3 months, and older children every 3-6 months. Trends matter more than one isolated result.
