Reading order is one of those PDF accessibility issues that can be easy to miss because the document may look completely fine on the page. Headings are in place, columns line up and charts sit where they should, but that visual layout doesn\u2019t necessarily tell you how a screen reader will move through the content.<\/p>\n\n\n\n

Screen readers rely on the PDF\u2019s underlying tag structure to determine what gets read first, what comes next and how different elements relate to one another. If that order is incorrect, the content can become confusing even when the design itself looks perfectly organized.<\/p>\n\n\n\n

In this guide, we\u2019ll look at how PDF reading order works, how to check it and what you can do to fix common issues before publishing.<\/p>\n\n\n\n

What is a reading order in a PDF?<\/strong><\/h2>\n\n\n\n

PDF reading order, also called logical reading order, <\/strong>is the logical sequence in which assistive technologies access and present the content of a document. According to W3C, reading order is determined<\/a> primarily by the order of elements in the PDF\u2019s tag structure rather than simply by where they appear visually on the page.<\/p>\n\n\n\n

A correct reading order allows someone using a screen reader to move through headings, paragraphs, images, tables and other content in a clear, logical sequence.<\/p>\n\n\n

Reading order vs. tag order: What\u2019s the difference?<\/strong><\/h3>\n\n\n\n

Tag order is the sequence of elements in a PDF\u2019s tag structure, while reading order is the sequence in which that content is presented to assistive technology. In a properly structured PDF, the tag order should create a logical reading order.<\/p>\n\n\n\n

This is why a PDF can contain all the right tags and still have an accessibility problem if those tags appear in the wrong sequence.<\/p>\n\n\n\n

Reading order, tag order and visual order describe different parts of how someone moves through a PDF. <\/p>\n\n\n\n
