An example of OpenDyslexic typeface

OpenDyslexic is a free typeface/font designed to mitigate some of the common reading errors caused by dyslexia. The typeface was created by Abelardo Gonzalez, who released it through an open-source license.[3][4] The design is based on that of DejaVu Sans, also an open-source font.

Like many dyslexia-intervention typefaces, most notably Dyslexie, OpenDyslexic adds to dyslexia research and is a reading aid, but it is not a cure for dyslexia.[5] The typeface includes regular, bold, italic, bold-italic, and monospaced font styles.

In 2012, Gonzalez explained his motivation to the BBC: "I had seen similar fonts, but at the time they were completely unaffordable and so impractical as far as costs go."[1] Two studies have investigated the effect of specialized fonts used with students with dyslexia. Rello and Baeza-Yates (2013) measured eye-tracking recordings of Spanish readers (aged 11–50) with dyslexia and found that OpenDyslexic did not significantly improve reading time nor shorten eye fixation.[6] In her master's thesis, Leeuw (2010) compared Arial and Dyslexie with 21 Dutch students with dyslexia and found Dyslexie did not lead to faster reading, but may help with some dyslexic-related errors.[7]

The typeface is currently an optional choice on many websites and formats, including Wikipedia,[8] Instapaper,[1] Kobo eReader,[9] Amazon Kindle Paperwhite, a few children's books,[10][11] and at least one imprint of classic literature.[12]

There is also a Google Chrome extension available,[13][14][4] which was developed by Abelardo Gonzalez and Robert James Gabriel.[4][15] It is also part of the "dyslexia-friendly mode" in Oswald Foundation's web accessibility products.[16]
