Dyslexia is a learning disability affecting many people worldwide, with percentages ranging from 5 to 20% of the population – the US National Institutes of Health estimates that one out of every five persons in the US suffers from dyslexia. One way people have tried combatting the symptoms of dyslexia is with fonts like Dyslexie (pictured here), which are specially designed to decrease the number of errors made by dyslexics while reading.
Dyslexie was created by Christian Boer, a dyslexic graphic designer at StudioStudio (Netherlands). The font incorporates a number of typographical features that make it harder for the brains of dyslexics to rotate, swap, mirror, and otherwise confuse letters while they’re reading.
Take the letters “p,” “b” and “d,” for example, depicted up top in Boer’s Dyslexie typeface. In many fonts, these letters look very much the same, such that by rotating and mirroring them they can be used more or less interchangeably.
In Boer’s font, however, the boldness of each letter’s base is increased, granting each character a “weight” that hints at its proper orientation. Notice also that the space enclosed by each letter (what is referred to in typography as a character’s “bowl” or “loop”) is shaped just a little differently than that of the other two. These subtle typographical cues may not seem like much, but they go a long way in helping your brain recognize which letters belong where when they appear in words and sentences.
