Authoring tools like Microsoft Word, Microsoft PowerPoint, and Adobe InDesign make creating accessible documents and presentations relatively straightforward. Rather than learning entirely new authoring methods, you may simply do the things you’re already doing, just a little bit differently. Even when a document is ultimately published as an accessible PDF, accessible design in the original authoring platform will allow for more sustainable and unchallenging efforts to apply modifications in the future.
Avoid serif fonts and ALL CAPS (outside of explained acronyms) for purposes of readability.
Use size 12 pt. font or larger for documents and size 18 pt. or larger for presentations.
Use the simplest language appropriate for your content.
Use columns, horizontal line separators, and empty (white) space strategically to improve readability.
Use images, graphics, and diagrams to dynamically supplement text.
Proofread for misspellings, grammar errors, and broken links.
Never use color alone to convey meaning.
Use headings, accessible tables, lists, and other structural tools to differentiate between categories. Color may still be used to supplement.
Ensure appropriate color contrast between foreground and background.
You can use an accessible, fillable PDF form by itself for information-gathering situations, in which a legal signature is not required. For purposes of validation and security, you should distribute externally-facing PDF forms that require a legal signature via a valid e-signature program like Adobe Sign.
