How to Fix the Reading Order in a PDF

Reading order is the sequence in which a screen reader announces the content of a page. It comes from the tag tree, not from where things sit visually. When the two do not match, the page looks fine but is read aloud in a confusing, out-of-sequence jumble.

Where reading order goes wrong

• Multi-column layouts read straight across both columns instead of down one then the next.
• Sidebars, pull quotes, and callouts get dropped into the middle of the main text.
• Captions are announced before or far away from the figure they describe.
• Headers and footers interrupt the body text on every page.

How to check reading order

In Acrobat Pro, the Reading Order tool and the Tags panel both show the order content is structured in. The Order panel numbers each element in sequence — reading down that list should match how a person would read the page.

How to fix it

1. 1Open the Tags panel (or the Order panel) in Acrobat Pro.
2. 2Compare the tag sequence to the visual reading flow of the page.
3. 3Drag tags up or down in the tree to put them in the correct order.
4. 4Move captions next to their figures and pull stray sidebars to a sensible spot.
5. 5Confirm headers and footers are artifacts so they do not interrupt the flow.
6. 6Re-check, then listen with a screen reader to verify the page makes sense aurally.

The fastest fix is often at the source: a clean single-column structure in Word or InDesign exports with the right order automatically.

Reading order is one of the issues a free check on this site will flag, so you know exactly which pages need attention.
