Video Accessibility Guide

Guidelines to ensure clear text:

• Black text on a white background is the easiest to read.
• If using colour, use high contrast colours for text and background.
• Good contrast pairings:
  • Black or dark blue text on white or yellow background.
  • White or yellow text on black or dark blue background.
• Restrict use of coloured text.
• Avoid using colour to assign meaning, unless you are explaining the meaning in your narration.
• Font should be at least 18 point size for videos using PowerPoint slides.
• Images of websites with text should be at least 12 point size.
  • If the text is small, considering zooming in, but make sure you narrate the action.
• Avoid crowding text on a slide.
• Opt for standard fonts with medium heaviness.

Other visual accessibility tips:

• If you are narrating visual cues or locations (eg: “click the big red button”) keep in mind that visually impaired users cannot see the screen and provide additional wayfinding options.
• If using graphics, make sure they are large, high-contrast, sharp, and clear.
  • Consider using a colour blindness tester for graphics
• If creating a text only screencast, provide an alternative format (eg: a PDF file) that can be read by screen readers.
