- Scenario
- Resizing a 112-page PDF document to meet specific layout or printing requirements.
- Observed behavior
- The document is currently formatted in 8.5 by 11 inches (Letter size) and needs its dimensions adjusted to exactly 8 by 5 inches.
Verify the exact dimension constraints required for your final output and ensure you have a saved copy of your original 112-page document to prevent accidental layout distortion.
Resize the PDF Using the Print to Custom Size Feature
The most reliable method to change page dimensions while scaling your content properly is to 'print' the document to a new PDF file using custom paper size settings.
Using a virtual PDF printer ensures that all pages are uniformly resized and allows you to adjust the scaling so that content is not cut off during the dimension change.
Open your PDF document in your preferred PDF reader or editor. Navigate to the 'File' menu and select 'Print', or press Ctrl+P (Windows) / Cmd+P (Mac).
In the Printer dropdown menu, choose a virtual printer such as 'Microsoft Print to PDF', 'WPS PDF', or 'Adobe PDF'.
Click on 'Properties' or 'Preferences' next to the printer name. Look for the 'Page Size' or 'Paper Size' option, choose 'Custom Size', and enter 8 inches for the width and 5 inches for the height.
Return to the main print dialog. Under Page Sizing & Handling, select 'Fit' or 'Shrink oversized pages' to ensure the original content scales neatly into the new 8x5 boundaries.
Click 'Print'. You will be prompted to choose a location to save your new file. Enter a new file name and click 'Save'.

Adjust Page Dimensions Using Advanced PDF Page Boxes
If you are using professional software like Adobe Acrobat Pro, you can directly alter the document's page boxes to force a new dimension.

Frequently Asked Questions
Will resizing a PDF from Letter to 8x5 distort my images or text?
If the aspect ratio of the new 8x5 size differs significantly from the original 8.5x11 size, content may appear distorted or cropped. Using the 'Fit to Page' scaling option during the Print to PDF process ensures your content shrinks proportionally to fit the new dimensions without distortion.
Can I simply crop the PDF instead of resizing it?
Yes, cropping removes the outer margins without scaling the internal content. However, to get an exact 8x5 dimension from an 8.5x11 document, you must remove 0.5 inches from the width and 6 inches from the height, which will likely cut off important text if the original document has small margins.
How do I change the page size for only specific pages in a PDF?
When using the print-to-PDF method or advanced page box tools, locate the 'Page Range' section. Instead of selecting 'All', choose 'Pages' and input the specific page numbers (e.g., 1-10) to apply the new custom dimensions only to those pages.
Why can't I edit the page size directly in my free PDF viewer?
Standard free PDF viewers are designed primarily for reading and basic annotation. Altering page dimensions structurally requires advanced editing features found in premium software like WPS PDF or Acrobat Pro, or utilizing a virtual PDF printer.
