Site Legibility

Site Legibility


  • The typeface and layout implemented on a page, as opposed to the style of writing

Legibility Guidelines

  • Use a narrow set of fonts across the site
    • Use sans serif fonts, such as Arial, Helvetica, or Geneva
    • Use 10 to 12 point fonts for most body text
  • Display your copy in chunks so that it is more scan-friendly
    • Do not use justification with paragraphs of text
    • Keep each line of text to 50 characters or less
    • Use simple graphic elements such as bulleted lists and numbered steps to make information visually accessible
  • Provide high contrast between text and background
    • Use dark text on light or white backgrounds
    • Use blue underlined text for links
    • Do not use underlines in regular text
