Contrast Ratio 4.5 to 1.

Contrast Checker for Text and Icons

WCAG 2.0 level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.  This means that light text can not be used on a white background.

Large text is defined as 14 point (typically 18.66px) and bold or larger, or 18 point (typically 24px) or larger.

WebAIM, a web accessibility solutions company, has a free online contrast checker.  Simply set the foreground and background colors, and the checker will automatically provide a pass/fail grade.

Adding Captions to Videos

Add Captions to Vimeo Videos


Always caption and/or transcribe prerecorded video to the highest quality possible.  Automated programs typically do not punctuate and articulate what is spoken with 100% accuracy.  Most often, the computer generated captions will require edits.  We ask that you pay close attention to the following:

  • Accuracy - Correctly identify who is speaking; match the dialogue verbatim; convey background sounds to the fullest extent with the captions remaining on screen long enough to be read in full.
  • Readability - Utilize proper spelling, punctuation, grammar and use of capitals in proper nouns and specialized terms.
  • Placement - Captions must be positioned so as not to block other visual content; no overlap, or run-off.  In general, captions are often best suited to run along the bottom of the video.
