Dyslexia Style Guide 2018: Creating Dyslexia Friendly
Content
This Style Guide provides principles that can help ensure that written material
considers the difficulties experienced by some dyslexic people and allows for the use
of text to speech to facilitate ease of reading. Adopting best practice for dyslexic
readers has the advantage of making all written communication easier on the eye for
everyone.
When making changes consider all the ways that you use written communications,
such as emails, presentations, web pages and printed materials. Consider these
principles in combination with other accessibility guidance such as the Web
Accessibility Content Guidelines (WCAG).
Readable Fonts
• Use sans serif fonts, such as Arial and Comic Sans, as letters can appear less
crowded. Alternatives include Verdana, Tahoma, Century Gothic, Trebuchet,
Calibri, Open Sans.
• Font size should be 12-14 point or equivalent (e.g. 1-1.2em / 16-19 px). Some
dyslexic readers may request a larger font.
• Larger inter-letter / character spacing (sometimes called tracking) improves
readability, ideally around 35% of the average letter width. If letter spacing is
excessive it can reduce readability.
• Inter-word spacing should be at least 3.5 times the inter-letter spacing.
