Christian Boer is a Dutch designer, who has dyslexia. Whilst completing his degree in Graphic Design at the Unifversity of Twente he designed this typeface. Conceived in 2008 after studying for a hard final exam, the typeface has heavier line thickness on the bottom of the glyphs to try and anchor the text, as many people with dyslexia find that the letter move whilst reading. The letter ‘p’, ‘q’, ‘b’ and ‘d’ are also altered to emphasise the differences as these letters are often confused by people with dyslexia. The font has had limited research with mixed results to show its efficacy. However if it works for you, that’s great! It’s available for home use for free and also available to licence here.
OpenDyslexic is a font released with an open source licence created by Abelardo Gonzalez another designer who has dyslexia. The font is open source and can be edited and used by anyone with just attribution back to the creators site at opendyslexic.org. OpenDyslexic is avaliable to use on my apps, websites and eReaders the open source nature has allowed wide adoption. Again their is little research to prove its efficacy but if it works for you it works! It is free to download here and is a font option on the Kobo eReader, Wikipedia and Instapaper to name a few.
Lexia Readable is designed by the type foundry K-Type. It takes a different approach from the previous typefaces designed to assist with reading literacy for people with dyslexia. The typeface is based on (sadly) Comic Sans, it removes the asymmetry of ‘p’, ‘q’, ‘b’ and ‘d’ and removes the childishness of Comic Sans, they mention that this is Comic Sans for the grown ups. K-Type offer it as a free download for non-commercial use, as with many of their fonts, or for a reasonable licence fee for commercial use here.
There are more fonts out there that have been made to help those with dyslexia. The ones we have here are free to use, at least, non-commercially. If you want to use them commercially please buy the licence or offer a donation as these designers have worked hard to create these typefaces. There is no strong evidence to suggest that any of these typefaces are actually effective reading aids, however, there is anectdotal support and if it works it works. We would love to hear from anyone that does have success in using these to improve reading comprehension, or anyone that has any other typefaces designed for dyslexia we have missed.
