The day my sister, Jessica, discovered Comic Sans, her entire world changed. She’s dyslexic and struggled through school until she was finally diagnosed in her early twenties, enabling her to build up a personal set of tools for navigating the written world.

“For me, being able to use Comic Sans is similar to a mobility aid, or a visual aid, or a hearing aid,” she tells me while we’re both visiting our family in Maryland. “I have other ways of writing and reading, but they’re not like they are for someone who’s not dyslexic.”

The irregular shapes of the letters in Comic Sans allow her to focus on the individual parts of words. While many fonts use repeated shapes to create different letters, such as a “p” rotated to made a “q,” Comic Sans uses few repeated shapes, creating distinct letters (although it does have a mirrored “b” and “d”). Comic Sans is one of a few typefaces recommended by influential organizations like the British Dyslexia Association and the Dyslexia Association of Ireland. Using Comic Sans has made it possible for Jessica to complete a rigorous program in marine zoology at Bangor University in Wales. […]

I asked Jessica to tell me what she’s up against. She’s been told that Comic Sans is “unprofessional. That it’s juvenile. That it’s stupid. That it basically shouldn’t be used for anything at all, unless it is a comic.”

There are fonts that have been specifically created for people with dyslexia, all of which lack the clean minimalism or elegant balance and perfect kerning favored by typography snobs. But they are crucial disability aids. Some are free, such as Lexie Readable (which calls itself “Comic Sans for grown-ups”), Open-Dyslexic, and Dyslexie. Others are for purchase or are publisher-owned and unavailable to the general public.

But for Jessica, Comic Sans is still the best. “I don’t use Open Dyslexic because it’s not as easy for me to read,” Jessica says. “It’s not my font. I was dyslexic before Open Dyslexic happened. My mind has been getting used to Comic Sans.”

Not everyone with dyslexia uses Comic Sans to help them read and write. “Other people with dyslexia find that having colored paper makes it easier,” Jessica says. “Or some people find Arial easier.”
Comic Sans and Arial are readily available because they are included by default in many operating systems and word-processing programs, and they are web-safe fonts.
