What inaccessible sites are like...
Videos

- Machine-generated captions are good, Human-generated captions are preferred.
- Ensure that all visuals used in a presentation are made available in an accessible format.
Fonts

- 12-point minimum font size in documents.
- 14-point minimum font on websites.
- 18-point font recommended on slides.
- Ensure adequate contrast between background color and text color.
Images
- All images require alternative text unless decorative.
- Alt-text should be descriptive of the content of the image and not the image itself.
- Do not solely use color to convey meaning.
- Minimize the amount of text in images and do not use image text-blocks.
- Keep image file sizes as small as possible.
- Ensure sufficient contrast in images and charts.
Headings
- Properly nest headings.
- Web pages must have at least one Level One heading.
Hyperlinks
- Use descriptive link text.
- Ensure links are long enough that the tap target is sufficiently large.
- Inform users when a link will open in a new tab.
Tables

Microsoft Word and Google Drive
