Quick Facts about Dyslexia Font and Styles:

• There are several fonts that have been designed for the dyslexic reader including Dyslexie, Opendyslexic, Gill Dyslexic, Read Regular, Lexia Readable, and Sylexiad
• Contrary to media hype, and even a Scientific American article about Dyslexie, no independent research has found that any font significantly improves reading speed or comprehension for dyslexics
  
• A 2013 Spanish study found that Helvetica, Courier, Arial and Verdana were the best fonts for dyslexics, the same fonts of choice for many efficient readers
  
• Lightly colored paper, 12-14 point sans serif font, and bolding of text for highlighting are commonly believed to be best for dyslexics
  
• Glossy and bright white backgrounds, italics, ALL CAPS, and underlining have been found to impair reading for dyslexics
  
• Dyslexics are always in style
  

Fonts Designed for Dyslexics

Below is a look at some of the major fonts developed for dyslexics, why they were developed, how they are supposed to work, and what the research (if any) has shown about them thus far.

Dyslexie

Dyslexic font common spelling and sounds workbook 3 is designed to reinforce common sounds. The lists are simple and repetitive, perfect for reluctant or dyslexic readers. It is also perfect for those starting out with learning the complexities of English spelling. It comprises primarily of lists of short vowel simple words (CVC), followed. That the Dyslexie Font is totally free to download and use, and you can get it by clicking here. Or you can visit the font’s website for more details. It’s a pretty cool innovation using font design that’s changing lives. Designing fonts with strong focus on readability (as opposed to merely aesthetics) is definitely a concept that. OpenDyslexic is an open source font intended to increase legibility and readability for people with dyslexia. With several hundred thousand users, it has become the most popular font targeting dyslexic users. The typeface includes regular, bold, italic, and bold-italic styles - and a variant including cursive letter 'a'.

Vocabulary

The terms Font and Typeface are often used interchangeably, but in fact they have different meanings...

Font: The delivery mechanism for printing. The medium

Typeface: Refers to the artistic design of the letters, numbers and symbols. The media.

One sentence captures the distinction....'I like the typeface of that dyslexia font.'

Unique Font Characteristics:

• Heavier line thickness at the bottom of most characters intended to better anchor letters
  
• Slight downward slant on the curvature of the letters. Letters such as 'c' or 'e' may gape slightly more, or slump slightly in one direction
• Elongates or diminishes the stem on some letters such as 'h and 'n'
  
• Thickens or bolds capital letters and punctuations, to better identify where sentences start or end
  
• Adds space between letters and words

Research Findings:

A masters thesis by Renske de Leeuw of the University of Twente found Dyslexie had no effect on reading speed but found an overall reduction in reading errors. Dyslexie was compared only against Arial and the sample size for the study was just 43, including 21 dyslexic readers. Though often cited by the design studio, the study is essentially neutral on the font's benefit. Perhaps they think people don't actually read it.

Open Dyslexic

Background

OpenDyslexic was created by American Abelardo Gonzalez and released as a free and open source font in 2011. He said he was motivated by the fact that other similar fonts (read: Dyslexie) were unaffordable.

Similarities with the Dyslexie font resulted in some nasty emails from Dyslexie creator Christian Boer, but the font remains free and open source.

The OpenDyslexic Font is Definitely Similar to Dyslexie

Unique Font Characteristics

• Letters have heavy weighted bottoms to indicate direction and help reinforce the line of text
• The unique shapes of each letter can help prevent the perception of letters reversing or swapping places
• Wider letter spacing than many fonts
• Unique italic styling

Research Findings

The OpenDyslexia website itself ernestly notes that there have been no formal studies conducted on OpenDyslexic while pointing out that there exist studies on font features that have been incorporated into the font such as extra space between letters.

Other Dyslexia Fonts, in Brief

Gill Dyslexic
This dyslexia font was created by the designer of Dyslexie, Christian Boer. It's not clear why he created a second font, though the cost is apparently less, so it may have been to compete with the cheaper Open Dyslexic, but it aims to reduce the symmetry between letters, making them easier to distinguish.
Like Dyslexie, the base of each letter is heavier than most other fonts, helping to orient the letter correctly. A sample sentence is below.

Gill Dyslexic Sample

Each character is designed to stand on its own and work together with its previous or next character. Ascenders (bdfhkl) and descenders (gjpqy) are longer than most fonts to ensure distinction. Spacing within the o, e, a and u is enhanced and the openings in e and g are kept from visually closing in.

I was unable to find any reference to research conducted on the font.

Lexia Readable

Designed by Keith Bates at K-Type and available for purchase at their website, Lexia Readable was designed as a more mature Comic Sans font, suitable for older readers (i.e. not just comic books). It was designed to be more legible at font sizes as small as 8 points.

The Lexia Readable Typeface is Airy and Open

The Regular and Bold weights are free for use without a license by individuals, educational and charitable organizations. For pay, licensed packages are also available

Long ascenders and descenders combine with generous letter spacing and asymmetrical lowercase b and d to help distinguish letters - features seen in Dyslexie and OpenDyslexic. No research was found to have been conducted on the font.

Sylexiad

Sylexiad is actually a collection of fonts designed by Dr. Robert Hillier, a Senior Lecturer at Norwich University College of Arts and sold at his website where he describes it as an 'ongoing design investigation'.

His PhD dissertation was conducted on the font, though focused mainly on reader preferences rather than reading speed or accuracy. Among his conclusions was that:

' for the majority of dyslexic readers tested it was the combination of handwritten style, uppercase forms, long ascenders and descenders, light weight, uniform strokes, perpendicular design and generous inter-word spacing that was preferred.'

Sylexiad Sans Serif Font is Lighter Weight than Some Other Dyslexia Font

Why Dyslexia Font Failure is Actually Good News

The failure of new fonts to make a significant difference vindicates a whole body of research that found dyslexia to be an auditory and cognitive processing impairment, not a visual one.
It's largely a myth that dyslexics see letters reversed, flipped or moving. Only a minority have such a problem. Therefore we should not expect a dyslexia font to have much of an impact.
Remember that decoding letters and words into meaning is a cognitive process that takes place in your brain, not your eyes! The input matters, but processing trumps all.

Final Font Thought: Don't Fret

My own education in researching dyslexia font has lead me to the conclusion that fonts really don't matter much, so long as they are clean (sans serif) and have generous spacing between letters and words, but this is as true for dyslexics as efficient readers.

But by all means experiment with different fonts. Some people have been literally brought to tears by the freedom a new font provided but these are anecdotal accounts and probably exceptional circumstances.

There is no hard research demonstrating improved reading speed or comprehension for dyslexics from any font.

A lot of good intent and effort went into the creation of the fonts and the media has given them a lot of gab but something has been missing from the whole discussion: Science.

The cutting edge of dyslexia research is converging on the fact that dyslexia results from inefficient processing of words in the brain— the way that letters and words are manipulated, stored and retrieved.

How could a font result in new global patterns of neural processing? If you understand this limitation, fonts are almost a non-starter.

Much of the rational behind the fonts is actually based on myths about dyslexia—that dyslexia is a visual problem wherein readers reverse letters or spin them around or can't distinguish one letter from the next. This is not the case for most people with dyslexia, their problem lies in discriminating sounds, being able to manipulate phonemes, lack of short term memory and inability to remain focused.

Writing Styles and Media

General Dyslexia Information Styling Tips

Things to Do:

• Left justify text
• Choose a simple sans serif font like Arial or Helvetica
  
• Use larger fonts and bolding to highlight text
• Use shorter sentences and paragraphs with ample line spacing
• Use numbering and bullets
• Use charts, graphs and other visual aids to present information
• Use lightly coloured matte finish paper
• Cream colours or pastels work well
• Use black text on lighter backgrounds
• Consider using audio text
  

Things to Avoid

Dyslexie Font On Word

• underlining or using italics because this tends to make it more difficult to parse words into their constituent parts and sounds
  
• words like former and latter, preceding, forthcoming or other terms associated with spatial or temporal sequencing
• ALL CAPS. The letters tend to fuse together
• acronyms and abbreviations
• bright white paper or backgrounds on webpages
• white text on black backgrounds, or at least not for the main body of text
