License
OpenDyslexic is a unique typeface in a sea of dyslexia–oriented typefaces. It was created because similar typefaces at the time were priced out of the reach of many people. There were many solutions, but no compassion. OpenDyslexic is free to everyone, including companies and corporations, putting it within reach of anyone. It was built on Jim Lyles’s Bitstream Vera Sans, based on public research many other typefaces are based on.

OpenDyslexic can be used in your commercial projects at no cost, even if it is the product of a corporation or other business. It may also be used on books, websites, flyers, videos, games, advertising, school material, and anything else you can think of.
