Fix Word Mirror Margins and Misaligned Text on Alternate Pages
Question details
The user needs to resolve an issue where text appears shifted and the ruler shows incorrect margin alignments when mirror margins are enabled in a document.

- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Setting up mirror margins for a document, specifically noticing alignment issues on the first page of a section or immediately after a section break.
- Observed behavior
- The on-screen ruler does not correctly update to reflect the inside and outside margins on alternate pages, causing the text to appear misaligned visually, despite the file previously working fine.
Before attempting to adjust your layout, check the Print Preview (File > Print) or export the document to PDF to confirm if the misalignment is a real formatting error or merely an on-screen visual glitch.
Verify Page Setup and Remove Unnecessary Section Breaks
Ensure that mirror margins are correctly applied to the entire document and that conflicting section breaks are removed to maintain consistent alignment.
In Microsoft Word, mirror margins are applied at the section level. Having multiple hidden section breaks can cause margin settings to act unpredictably on alternate pages.
Navigate to the 'Layout' tab on the ribbon, click on 'Margins', and select 'Custom Margins' from the bottom of the drop-down menu.
In the Page Setup dialog, locate the 'Pages' section. Set 'Multiple pages' to 'Mirror margins'. Then, change the 'Apply to' drop-down menu to 'Whole document' and click 'OK'.
Go to the 'Home' tab and click the 'Show/Hide ¶' icon in the Paragraph group to display hidden formatting marks, including section breaks.
Scroll through your document and delete any unnecessary 'Section Break (Next Page)' or 'Section Break (Continuous)' markers that might be disrupting the mirror margin flow.

Update or Repair Microsoft Office
Since the ruler misalignment is a known bug in certain builds of Word, updating or repairing your software can replace corrupted files and apply official bug fixes.

Frequently Asked Questions
Why does the ruler not match my mirror margins on the first page?
This is often caused by a known display glitch in certain versions of Microsoft Word (such as Word 2016). The ruler fails to dynamically update its inside and outside margin indicators on the first page of a section or document, even though the actual text margins are set correctly.
How can I check if my mirror margins will print correctly despite the display bug?
You can verify your true margins by going to File > Print to view the Print Preview, or by exporting the document as a PDF. If the margins appear correct in the preview or the PDF file, they will print properly regardless of the on-screen ruler's appearance.
Do section breaks affect mirror margin formatting?
Yes, mirror margins are configured at the section level. If you insert a new section break, it might revert to default margins or trigger a visual ruler glitch on the page immediately following the break. It is recommended to apply mirror margin settings to the 'Whole document' to prevent conflicts.
