Dyslexia is a learning disorder that is found in certain genes that affect parts of the brain that processes reading and language. This hinders the person’s ability to identify speech sounds and decoding letters and words. In 2017, 5-10% of the world’s population has dyslexia, according to Dyslexia International, which is around 700 million people. There is no cure for dyslexia but there are ways in which typographic designers can help those with it.

Designing for Dyslexia:

  • Sans serif typefaces are best suited for those with dyslexia
  • They provide a simple design which allows ease for reading
  • This includes the default typefaces in many programs such as InDesign (Myriad Pro) and Microsoft Word (Arial)
Content design
  • Using 1.5 – 2 line spacing can help with reading large body copies
  • Breaking up paragraphs to be shorter helps with the issue of losing track of where the viewer is
  • Avoid unnecessary italics, underlining, or all caps as it disrupts the readability
  • Use a consistent heading and structure to help with navigation
Layout and graphics
  • Avoid using a white background because it creates too high of a contrast
  • Left align text, no justification
  • Utilize images and diagrams to support your text and rest the viewer’s eyes
  • Enable the user’s ability to customize text colour, size, or typeface to better suit their specific needs
Things to keep in mind while designing
  • Readable fonts
  • Headings and structure
  • Colour
  • Layout
  • Writing style

What has been done:

Christian Boer, a graphic designer with dyslexia designed a typeface to specifically combat dyslexia and help those who suffer from it. When designing his dyslexia-friendly typeface, Boer implemented numerous changes, such as:

  • Heavier bottoms

  • Different shapes


  • Longer stems


  • Emphasize punctuation and capital letters


  • Inclined letters


  • Bigger counters


  • Varying heights


  • Higher x-height


List of dyslexia-friendly typefaces:

  • Dyslexie
  • OpenDyslexic
  • Lexia Readable
  • Read regular
  • Tiresias
  • Sassoon
  • Barrington stroke
  • Myriad pro
  • Century gothic
  • Comic Sans
  • Verdana
  • Arial

What to avoid when designing for dyslexia:

Justified text

  • Large, uneven spaces between words make the white space too distracting for the viewer



  • Most websites use typefaces that are proportionately spaced, using a double space, disrupts the consistency
  • Using a double space after a period can create “rivers” which makes it difficult for the reader to locate the end of a sentence


Pure black text on white background

  • The contrast is so high, to some it may cause the text to become warped


Long paragraphs

  • Can get lost with no breaks in a large body copy


Serif fonts

  • The serifs obscure the shape of the glyphs



  • The tilt in the letterform makes it hard to read
