Dyslexia

Dyslexia is a common, lifelong difference that affects reading, spelling, and how written language is processed. Many people with dyslexia use text-to-speech, or need to adjust fonts and spacing before reading is comfortable. It often comes alongside ADHD.

The W3C's user story for Stefan, a student with dyslexia and ADHD, describes adjusting font, text size, line spacing, and background colour to read comfortably, paired with read-aloud software that highlights words as it speaks. He hits a wall with scanned PDFs that can't be resized or read aloud, walls of text with no headings, and search boxes that return nothing when he misspells a word.

Publish real text, not images of text. Respect users' browser settings for font and spacing. Break long content up with headings. And if someone misspells a search term, suggest what they probably meant.
