New Accessibility Techniques for PDF: Lists

November 2025 by PDF Association staff

The PDF Association’s third release of its Techniques for Accessible PDF focuses on lists!

This new guidance offers 15 correct (PASS) and 10 incorrect (FAIL) examples of list tagging to help authors properly tag lists in PDF documents.

Proper tagging supports assistive technologies, ensures correct list semantics (ordered, unordered, nested, etc.), and enables accurate reflow and conversions. The provided techniques and failure examples cover all basic types of lists and address common pitfalls. As always, these techniques are vendor-neutral and community-maintained.
