What is Open Dyslexic?
OpenDyslexic is an open-source font designed to improve readability for individuals with dyslexia and those who struggle with standard text formats. The font's unique design features, such as distinct letter shapes and increased vertical spacing, aim to reduce confusion between similar characters and enhance visual differentiation. It is primarily used by educators, students, and individuals with learning disabilities to access educational materials, digital content, and everyday text more comfortably. By addressing common challenges in reading, such as letter confusion and poor text flow, OpenDyslexic provides a practical solution for users who may find traditional fonts overwhelming or difficult to process. The project emphasizes accessibility and inclusivity, ensuring that text remains legible across various digital platforms.
How it works
OpenDyslexic is a typeface developed to support readability for dyslexic readers and others who benefit from alternative text formatting. Its design prioritizes distinct letter forms, with heavier bottoms on characters to anchor them visually. The font addresses challenges like letter confusion (e.g., 'b' vs. 'd') and poor text alignment by using asymmetrical shapes and increased spacing. It is available under the Open Font License (OFL-1.1), allowing free use and modification. The font includes specialized glyphs for letters like 'a', 'e', and 't' that are more distinguishable. It also features a vertical baseline to prevent letters from appearing too similar. These design choices are intended to aid in text recognition and reduce eye strain during reading.
How to use it
- 1Obtain font files (eot, otf, ttf, woff) from the project's hosted repository. 2. Install the font on your operating system or embed it via CSS in web projects. 3. Apply the font to text using CSS or font-face declarations. 4. Test readability across devices and platforms to ensure consistent rendering.

Frequently asked
What is OpenDyslexic and who benefits from it?
OpenDyslexic is a typeface designed to improve readability for individuals with dyslexia and others who struggle with standard text formats. It benefits readers who experience difficulty distinguishing similar characters, poor text alignment, or visual processing challenges. The font's distinct letter shapes and spacing help reduce confusion and enhance text comprehension.
How does OpenDyslexic's design differ from standard fonts?
OpenDyslexic uses asymmetrical letterforms with heavier bottoms to anchor characters visually, unlike standard fonts that often have symmetrical shapes. Letters like 'a', 'e', and 't' are designed with unique structures to prevent confusion. The font also employs increased vertical spacing to improve text flow and reduce eye strain during reading.
How can I apply OpenDyslexic to a website?
To use OpenDyslexic on a website, download the font files (eot, otf, ttf, woff) from the project's hosted repository. Then, use CSS @font-face to declare the font and apply it to text elements. For example: @font-face { font-family: 'OpenDyslexic'; src: url('open-dyslexic.woff2'); } body { font-family: 'OpenDyslexic', sans-serif; } Ensure the font is hosted publicly or distributed under the OFL-1.1 license.
How does OpenDyslexic compare to other dyslexia-friendly fonts?
OpenDyslexic differs from alternatives like Lexia Readable or Neuland by focusing on distinct letter shapes and vertical alignment. While Lexia Readable emphasizes larger letterforms, OpenDyslexic prioritizes asymmetry and spacing. Neuland, a decorative font, is less suited for long-form reading. OpenDyslexic's design is tailored for accessibility rather than stylistic appeal.
What should I do if the font doesn't render correctly?
If OpenDyslexic appears distorted or incomplete, check that the correct font files are loaded and that the CSS declaration is properly formatted. Ensure the font is hosted on a reliable server or embedded directly. If using a browser, clear the cache and test on multiple devices. Verify licensing compliance to avoid conflicts with font distribution rules.
