Questions
Is the calculator free to embed?
Yes. It is free for blogs, clinics, doulas, lactation consultants and any site about babies. There are no ads inside it. Please keep the short credit line under the calculator.
What data does it collect?
None. The calculator runs in the visitor’s browser; the date of birth and the measurements are not sent to Growthling or to your site.
Which growth charts does it use?
The WHO Child Growth Standards (birth to 5 years), the same charts used by the CDC for children under 2, the UK-WHO charts, Brazil’s Caderneta da Criança and most national child health records. Visitors can also switch to the CDC infant charts (birth to 36 months).
Is it available in other languages?
Yes: English, Portuguese and Spanish. Pick the language in the code below.
Will it fit my layout?
It is responsive and resizes its height to the content when you include the small script in the code. Without the script it uses a fixed height of 900 pixels.
