Dos and don'ts: Designing for users with dyslexia

Do

• use images and diagrams to support text
• align text to the left and keep a consistent layout
• consider producing materials in other formats (for example, audio and video)
• keep content short, clear and simple
• let users change the contrast between background and text

Don't

• use large blocks of heavy text
• underline words, use italics or write capitals
• force users to remember things from previous pages - give reminders and prompts
• rely on accurate spelling - use autocorrect or provide suggestions
• put too much information in one place
