Fix Word Ignoring Custom Page Size When Printing to PDF
Question details
The user needs to maintain accurate custom page dimensions when converting a Word document to a PDF file.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Attempting to print or export a document with custom page dimensions to a PDF file.
- Observed behavior
- Word displays the custom page size correctly in the document workspace, but the resulting PDF or printer driver reverts to a standard paper size like Letter or A4.
Before proceeding, check the Page Setup menu in your document to note down the exact width and height of your custom page size.
Use Native 'Save As' PDF Method
Bypass virtual printer drivers by using Word's built-in PDF saving feature, which is more reliable for preserving custom page dimensions.
Virtual PDF printers (like Microsoft Print to PDF) often force standard paper sizes based on their driver settings. Using the native 'Save As' feature uses the word processor's internal rendering engine instead.
Open your document in Microsoft Word, click on the 'File' tab in the top-left corner, and select 'Save As' from the left sidebar.
Choose a destination folder on your computer. In the 'Save as type' dropdown menu, select 'PDF (*.pdf)'.
Click 'Options' if you need to adjust publishing settings. Otherwise, click 'Save' to export the file. Open the resulting PDF to verify the custom size was retained.
Check Print Preview and Paper Size Settings
Ensure the printer options match your document's custom dimensions before confirming the print-to-PDF job.
Update Your Printer Driver Package
Outdated or generic printer drivers might not support custom paper sizes, forcing the output to default to standard dimensions.
Use WPS Office to Accurately Save Custom Page Sizes as PDF
If your current word processor struggles with custom page dimensions, WPS Office offers a built-in PDF export tool that perfectly preserves your exact layout, margins, and custom sizes without relying on external or virtual printer drivers.
- 1. Open Your Document: Launch WPS Writer and open the document containing your custom page setup.
- 2. Verify Page Layout: Navigate to the 'Page Layout' tab and click 'Size' to ensure your custom dimensions are correct.
- 3. Export to PDF: Go to the 'Menu' button in the top left, select 'Export to PDF', configure your settings, and click 'Export' to generate a perfectly sized PDF file.
Frequently Asked Questions
Why does my PDF default to letter size instead of my custom size?
This commonly happens because the virtual PDF printer driver acts as a middleman and enforces its own default paper settings, which overrides your document's layout. Using the direct 'Save As PDF' function bypasses this issue.
How do I set a custom page size before attempting to export?
In your word processor, go to the 'Layout' or 'Page Layout' tab, click 'Size', and select 'More Paper Sizes'. In the Page Setup dialog box, enter the specific width and height you need, then click OK.
Does saving as PDF work better than printing to PDF for layouts?
Yes, saving or exporting directly to PDF utilizes the native rendering engine of the application. It typically handles complex elements, custom page sizes, and hyperlinks much better than routing the file through a virtual 'Print to PDF' driver.
