How to Fix Margin Changes When Converting Word to PDF
Question details
The user is experiencing unexpected layout shifts where top and bottom margins change and font sizes slightly decrease when exporting a document to PDF.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Converting a Microsoft Word document to a PDF file using Acrobat PDFMaker or Microsoft Print to PDF.
- Observed behavior
- The resulting PDF has expanded bottom margins and slightly shrunken font sizes compared to the original Word document layout.
Before altering your layout, try testing the conversion using 'Microsoft Print to PDF' versus your standard PDF add-in to confirm if the margin shift is caused by the document's structure rather than a specific third-party converter.
Adjust Margins and Insert a Blank Header
Modify the document's page layout by intentionally reducing the bottom margin and adding a blank header to offset the scaling effect during PDF conversion.
In some cases, Microsoft Office inherently scales documents slightly when sending them to a PDF printer, which can result in larger bottom margins and slightly smaller fonts (e.g., 10-point text becoming 9.96-point). Manually adjusting the page settings helps neutralize this shift.
Open your document in Microsoft Word. Navigate to the 'Insert' tab, click on 'Header', and select the 'Blank' template to add an empty header space.
Go to the 'Layout' or 'Page Layout' tab on the top ribbon, click on 'Margins', and select 'Custom Margins' at the bottom of the drop-down menu.
In the Page Setup dialog, decrease the 'Bottom' margin value. For example, if it is currently set to 0.75 inches, change it to 0.25 inches to compensate for the added spacing.
Save your changes and convert the document to PDF again. Check the new PDF file to confirm that the margins now align with your desired formatting.

Frequently Asked Questions
Why do my margins change when saving a Word document as a PDF?
This usually happens because the PDF converter or virtual printer attempts to scale the document to fit a specific printable area, causing the layout engine to expand the margins and slightly shrink the text.
Does paper size affect PDF margins during conversion?
Yes. If your original Word document is set to one paper size (like A4) and the default paper size in your PDF printer settings is different (like Letter), the layout will be forced to scale, directly altering your margins.
Can I prevent font sizes from shrinking in the converted PDF?
While a very slight font reduction is a known quirk in certain versions of Microsoft Office to PDF conversions, fixing the overall page scaling by adjusting margins or matching paper sizes usually resolves the visibly noticeable text shrinkage.
Are there alternative ways to convert to PDF without layout changes?
If adjusting headers and margins does not yield perfect results, consider using alternative software with built-in, native PDF export capabilities, such as WPS Office, which maintains strict fidelity to your original document layout.
