I've come across this question on Quora where it's likely to be forgotten.

Unlike other disabilities that are often considered in design, dyslexia has many forms. As a result, the guidelines can't be just one-liner, such as "use X font" or "make sure contrast ratio is Y".

The best answer must cite hard evidence.

  • There's some attempted "dyslexic fonts" but that's all I'm aware of in particular – Ben Brocka Mar 22 '12 at 18:35
  • @BenBrocka: Yeah. I found a couple of questions where "dyslexic-friendly" fonts came up but nothing thorough. – dnbrv Mar 22 '12 at 18:40

    "The best answer must cite research studies." You really expect someone to do all this homework for you? – Diodeus - James MacFarlane Mar 22 '12 at 19:52
  • @Diodeus: Just like I do homework for others. – dnbrv Mar 22 '12 at 20:02

There a number of one pagers that talk about how you might design a site for users with dyslexia, I would recommend this three part series Designing for Dyslexics as a solid foundation:

  • Part 1 (Definition of dyslexia, population size, implications/effects)
  • Part 2 (Lower color contrast & visually impaired users)
  • Part 3 (Typography, layouts, language style, information architecture, screen readers)

Here is a style guide from the British Dyslexia Association.

  • Wow. I'm pleasantly surprised that such rare & specialized materials were found so quickly! – dnbrv Mar 22 '12 at 22:21
  • "Use a plain, evenly spaced sans serif font such as Arial and Comic Sans" :-/ – Roger Attrill Mar 23 '12 at 7:32
  • @RogerAttrill it's talking about readability, not good looks :) Comic Sans WAS designed for easy readability, albiet on low resolution devices. – Ben Brocka Mar 25 '12 at 23:35
  • Comic Sans just happens to be more suitable than most from the commonly available fonts, but nevertheless was not designed with dyslexia (or even early reading) in mind. On the other hand specialist fonts such as Lexia Readable, Dyslexie and Read Regular which tackle the specific issues may prove superior, especially when trying to be inclusive of dyslexic readers but not exclusive to them. – Roger Attrill Mar 26 '12 at 8:46
  • Better late then never: the accessites articles are detailed, and contain a lot of information. However, the author makes a large number of claims about (amongst other things) dyslexia but never references any sources. – Blubber Jun 26 '14 at 12:38
