Dyslexie typeface by Dutch designer Christian Boer. “When they’re reading, people with dyslexia often unconsciously switch, rotate and mirror letters in their minds,” said Boer, who is dyslexic himself. “Traditional typefaces make this worse, because they base some letter designs on others, inadvertently creating ‘twin letters’ for people with dyslexia. For example, in Swiss typeface Helvetica, the letter ’n’ is used upside down as a ‘u’, ‘d’ is a back to front ‘b’, and ‘q’ is a mirrored ‘p’.
In his typeface, Boer uses heavier bottom portions to prevent the reader flipping letters upside down. letters that are similar are altered slightly to reduce the likelihood of confusion so each letter is unique. Wider letter spacing and bolder punctuation also helps one sentence reading into the next.
