When most of us go about everyday tasks, we take for granted the reading that’s involved, on instructions, labels and so on. For people with learning disabilities, reading is made much harder by certain fonts. FS Me is designed specifically to improve legibility for people with learning disabilities. The font was researched and developed with – and endorsed by – Mencap, the UK’s leading charity and voice for those with learning disabilities. Mencap receive a donation for each font license purchased. Every letter of FS Me was tested for its appeal and readability with a range of learning disability groups across the UK.
