InfantChart is a free web-based calculator for assessing growth in infants, toddlers, and children. It generates percentiles and Z-scores based on metrics such as weight, length/height, head circumference, and BMI. It is not a developer tool in the typical sense, but more of a health and medical reference calculator. That said, the implementation notes suggest the author emphasizes an engineering-oriented approach to data handling and testing.
The site covers multiple growth chart standards, including WHO 0–24 months, 0–5 years, and 5–19 years; CDC 0–36 months and 2–20 years; China national standards; Down Syndrome/Zemel; Preterm/Olsen; and more. Its calculations are based on official LMS parameters rather than approximate readings from chart images, and it claims to cross-validate results against WHO and CDC reference calculators as well as public examples. The Growth Dashboard allows users to enter measurements once and match them with the appropriate charts, while highlighting the age-range charts recommended by the AAP.
The site clearly describes itself as a free tool, with no registration or account required, and states that it does not store data. Its terms mention the use of Google AdSense ads, so its business model may be ad-supported. No paid plans, enterprise editions, or payment options were found.
Its strengths are that it is free, easy to use, covers a wide range of standards, clearly explains its data sources and calculation methods, and provides the author’s background, contact information, and channels for reporting errors. For parents and frontline healthcare workers, it is convenient for quickly checking percentiles. The downside is that it is not positioned as a developer platform: it does not provide an API, SDK, CLI, webhooks, embeddable components, or a self-hosted version, and it does not claim to be open source. The terms also state that all content, formulas, code, and design are protected by intellectual property rights and may not be copied or used to create derivative works without permission.
It is suitable for parents who want to track their child’s growth between pediatric visits, as well as nurses, lactation consultants, public health workers, and students who need to quickly reference standard growth curves. If developers want to integrate growth percentile calculations into their own products, the current information on the website is not sufficient to support direct integration.
The scraped text did not provide information about access from mainland China. The site includes China national standard curves, which makes it somewhat valuable for Chinese-language contexts or Chinese child growth references. However, whether it can be accessed reliably without a VPN, and whether Google ads affect loading, would need to be tested directly.
