Although there are many aspects to consider when evaluating a document for accessibility, these are the Top 7 Accessibility Considerations for Digital Documents when creating a new document OR when evaluating the accessibility of an existing document.
- Sans serif fonts are best for smaller text or chunks of text.
- Reserve serif fonts for headings and titles.
- Limit the use of script and decorative fonts.
- Accepted guidelines:
- Minimum of 12 point font for documents.
- Minimum of 20 point font for presentations.
Use the semantic heading structure available in the “ribbon” of your word processing application to indicate the hierarchy of headings throughout the document. This should seem similar to an outline.
The basic Idea:
The title should be a level 1 heading. There is only one level 1 header in the entire file. Level 2 headings will be for any sectioning within the document. Meanwhile, level 3, 4, 5, and 6 headings will be used to further breakdown each topic, idea, chapter, etc. into smaller sections.
On this page the heading levels (shown as <h1> for level 1, <h2> for level 2, and so on…) are:

When making a list, use the tools provided to create bullets, numbering, or outlining. These tools create the semantic structure for unordered or ordered lists. Avoid using dashes, astericks, tabbing, or self-numbering
- Avoid using color as the only means of representation or emphasis. (Color plus one).
- Be sure that there is enough contrast between the text and the background.
- Use black backgrounds with white text sparingly.
- Avoid busy backgrounds in presentations so as not to distract from the text.
- Limit the number of colors used per document or per slide.
This is an application that is downloaded to your computer. It can be used with Microsoft, Google, and Apple products. I highly recommend this resource.
This helps with choosing an accessible color palette. It’s fun to use!
Avoid pasting in a long, random URL by creating hyperlinks with custom text. When writing custom text for your hyperlink, you should also avoid phrases that are not descriptive like “read more” or “click here.” The best hyperlink text concisely conveys the link destination and makes sense when read out of context.
Non-decorative images within digital documents require alternative text, frequently referred to as “alt text.” Alt text can be add in most applications by right-clicking (or command-clicking) and selecting “Edit alt text” from the drop down menu. Good alt text is a brief description of the content and the function of the image. Images that are only added for decorative purposes and do not add context to the document should be marked as “decorative.”
When a video or audio element is embedded in or linked to from a digital document captions or a transcript of the audio is required.
