Web Design to Accommodate the Dyslexic Reader

Dyslexia a general term for disorders that involve difficulty in learning to read or interpret words, letters, and other symbols, but that do not affect general intelligence. It is the most common cause of reading, writing, and spelling difficulties.

Of people with reading difficulties, 70-80% are likely to have some form of dyslexia. It is estimated that between 5-10% of the population has dyslexia, but this number can also be as high as 17%.

Here are some CSS tips to consider when designing web content for dyslexics.

Beware Italics
Italicized characters can be difficult for dyslexics to read.

Column Widths
Use narrow column widths (60 to 80 characters). Tracking lines of unbroken text across a page can be difficult.

No Justification
Never use justified text. It causes "rivers" that make text difficult for dyslexics to read.

Use Sans-serif Fonts
Serif fonts (like Times Roman) have "feet" at the end of the letter strokes. This can be a nightmare for dyslexics to read because the letters look like they are all connected. Use sans-serif fonts.
