Everyone is Welcome!

Though we may dread yet another meeting in front of our computer screens these days, our move to connecting with each other via Zoom and other video conferencing platforms has had at least one silver lining: accessibility.

Princeton University is committed to providing a welcoming and inclusive environment that is welcoming, accessible, engaging, and exciting to all participants and viewers. Keep this guidance and these best practices in mind as you create presentations to make your events and videos accessible to people with permanent or temporary disabilities. Many of these practices will benefit all viewers!


  • Princeton University’s Media Central platform can provide captioning for Princeton students, faculty, and staff. Presenters are encouraged to submit a list of vocabulary terms from a transcript of their video at the time of submission to facilitate accuracy in the captioning process.
  • Aira is another useful captioning tool.


  • Select visuals carefully to enhance the presentation without introducing information not covered in the narration.
  • If using slides, err on the side of fewer rather than many.
  • Use high-contrast colors, and do not rely on color alone to convey information.
  • Limit the information on each screen or slide to what is absolutely necessary.
  • Make graphics as simple as possible.
  • Avoid presenting images of complex charts or tables. Highlight only the most important information.


  • Use an easy-to-read, sans-serif font, such as Arial, Calibri, Helvetica, Tahoma and Verdana. (An example of a “serif” font is Times New Roman).
  • Limit the lines of text on each slide to no more than three lines.
  • Use large, easily visible headings, such as Arial 44-point bold.
  • Use 28-point or larger font for body text. Simplify by using keywords, brief and concise phrases, and avoiding complete sentences.
  • Avoid using italics for emphasis; Use bold instead.
  • Use lists, with bullets or numbering wherever possible.
  • Left justify text.
  • Use plenty of vertical spacing between lines.


  • Speak clearly, loudly, and slowly.  (Assume two minutes of reading aloud per double-spaced page in 12-point font).
  • Describe visuals for people with visual impairments, for those who are viewing on a small screen, and for those who may have difficulty understanding the visuals.
  • Describe the information depicted in your visuals. Be specific about the layout and the data shown, keeping in mind that those who cannot see the visuals depend on your description to access the information they contain.
