EnglishWhat Is OpenDyslexic and What Is It Designed For?
Updated
OpenDyslexic is a typeface designed to counter some common symptoms of dyslexia. It is intended for readers who find text easier to read in this font than in conventional typefaces. The official site presents it as free to use under the SIL-OFL license, covering personal, business, educational, commercial, book, ebook reader, application, and website projects.
What problem it addresses
Dyslexia can make ordinary text harder to decode, and typeface design is one factor that may affect reading comfort. OpenDyslexic is positioned as a design response to some of those common symptoms rather than as a teaching method or a diagnostic tool. The site's own framing is practical: if you like the way the page reads in this typeface, it is meant for you.
Who it is for
- Readers who want to try a dyslexia-oriented font for screen or print reading.
- Educators, publishers, and developers who want to offer an alternative font choice.
- Anyone building books, ebooks, apps, or websites who needs a licensed font they can redistribute or embed.
License and cost
According to the site, the newest version uses the SIL-OFL license, which permits personal, business, educational, commercial, book, ebook reader, application, and website use. The font is free to download and use, with no mandatory fees. Donations are optional: you can give any amount when downloading from Itch.io, subscribe via Patreon to support ongoing costs, or email the contact address for other donation methods.

How to get it and verify it works for you
- Go to opendyslexic.org and use the Download entry point.
- Download the font, optionally donating any amount through Itch.io.
- Install it in your operating system or load it in your project, then compare a page of your own text in OpenDyslexic against your usual font.
- Expected result: you can judge whether the letterforms reduce the reading friction you experience. If they do not, the font is simply an option you can set aside.
A practical check is to test the same paragraph at the same size and spacing in both fonts, since perceived readability depends on layout as well as letter shape.
