- PDF Editor
- Device & OS
- not provided
- Scenario
- Changing the page size and orientation of an existing PDF from US Letter to portrait A4.
- Observed behavior
- Users often experience issues with incorrect page resizing, horizontal orientation instead of vertical, unwanted cropping, or improper content scaling when attempting the conversion.
Determine whether you need to actually alter the digital PDF dimensions or simply print the document onto physical A4 paper, as this will dictate the conversion method you should use.
Resize the PDF Page Size Using the Print to PDF Feature
The most reliable way to convert page dimensions without specialized editing software is by re-printing the document using a virtual PDF printer with A4 settings.
By utilizing a virtual 'Print to PDF' service, you can force the document into a new page dimension while leveraging built-in scaling options to prevent your text or images from being cropped.
Open the target Letter-size PDF in your preferred PDF reader or editor.
Navigate to the 'File' menu and select 'Print', or press the Ctrl + P (Windows) / Cmd + P (Mac) keyboard shortcut.
Change your selected printer to 'Microsoft Print to PDF' or the built-in PDF virtual printer of your software.
Click on 'Properties' or 'Page Setup', change the Paper Size to 'A4', and ensure the orientation is strictly set to 'Portrait' (Vertical).
Set Page Sizing & Handling to 'Fit' or 'Shrink oversized pages' to ensure the Letter content scales correctly onto the A4 page, then click 'Print' to save the newly formatted PDF.
Re-export from the Original Source Document
If you have access to the original source file (such as a Word document), changing the page size there before exporting yields the highest quality PDF.

Frequently Asked Questions
What is the exact size difference between US Letter and A4?
US Letter measures 8.5 by 11 inches (215.9 x 279.4 mm). A4 is slightly narrower and taller, measuring 8.27 by 11.69 inches (210 x 297 mm). Because of this difference, converting between the two requires careful scaling to prevent cropping.
Why is my text getting cut off on the sides when converting from Letter to A4?
Because A4 is narrower than Letter format, any content that extends close to the left and right edges on the original document may be cropped. To prevent this, ensure your conversion settings use 'Fit to Page' or 'Shrink to Printable Area' so the content scales down proportionately.
Can I permanently change the PDF page size without printing to a new file?
Directly altering the physical canvas size of a PDF without re-printing usually requires advanced PDF editing tools to crop or resize the page boxes. Re-printing via a virtual PDF printer or re-exporting from the original source file is typically the fastest and most accessible method.
