When we were designing the cards for Tiree in Your Words, we chose a font (this one) that is a little quirky, and at our planning meeting with our collaborators one of them pointed out that it might be quite difficult for people with impaired vision to read. People really liked the font, though, so we decided to create a large print insert and while doing that I looked up some guidelines for producing legible text. I’d always understood that serif fonts are easier to read than sans fonts, and was surprised to find that research doesn’t support this. These documents contain a lot of interesting information and advice for anyone who cares about accessible typography.

- Clear Print Design Standard from CNIB, Canada
- typography for visually impaired people from information design consultancy Text Matters
- and the RNIB’s Fonts page.
(In case you’re curious, I printed the inserts in Baskerville font.)
