Universal Design: Cross-Platform Accessibility Best Practices

Follow These Best Practices to Ensure that Your Materials are Accessible to All

  • Using the heading features and other options such as bullet lists provide structure to a document or slideshow. They also make it easier for those using a screen reader to better access a document.
  • Adding alt (alternative) text to an image allows for those who use screen readers the option to listen to a description of an image.
  • Use embedded links rather than including the entire URL.
  • Use suggested font styles such as Arial
  • Use a color scheme that provides enough contrast between the text and the background. Check your color combinations at the WebAIM Contrast Checker.
  • Make sure any video that you use has captions.

Poster Accessibility Best Practices

  • Choose a title that illustrates what your poster is about and be sure that the title is at least twice the size of your regular text. Use recommended sans-serif fonts such as Arial, Gill Sans, Helvetica, and Verdana for body and heading text. Times New Roman and Garamond are recommended for headings only. Some suggested sizes: 

  • Main title: 72 point (minimum) - 158 point (ideal) 

  • Section headings: 42 point (minimum) - 56 point (ideal) 

  • Body text: 24 point (minimum) - 36 point (ideal) 

  • Captions: 18 point (minimum) - 24 point (ideal) 

  • Organize your poster by Introduction, Methods and Results. State your aims at the end of the Introduction. 

  • Use structure in your poster by using headings and bullets. 

  • Avoid fuzzy images; make sure all graphics are high-resolution and easily visible. 

  • The figures and tables should cover approximately 50% of the poster area and be strategically incorporated onto the poster (include title and figure legends for your figures and tables). 

  • Keep text to a minimum, seek simplicity and avoid redundancies. Remember, you are not writing an article. Let your important points stand out. If possible, avoid abbreviations and acronyms, especially in the Conclusions. 

  • Use embedded links rather than including the entire URL. Here are instructions on how to insert links in PowerPoint slides

PowerPoint-Specific Accessibility Best Practices

  • Use at least 20 point font.
  • Avoid transitions and animations.
  • Simple background with high contrast to the font and other images.
  • Do not overload your slides with information.
  • Include unique titles for each slide in your presentation.
  • Include audio/video content in alternative formats.
