- Scenario
- Preparing a PDF document for distribution and printing on a specific paper size.
- Observed behavior
- The user needs to know how to enforce A5 printing, but printer hardware settings often override document settings, requiring manual adjustment by the recipient.
Before modifying your document, be aware that while you can change the PDF's internal page dimensions to A5, you cannot remotely override the physical paper tray settings of another user's printer.
Set the PDF Page Dimensions to A5
Change the actual page size of your PDF document to A5 so that it defaults to this size when opened in any PDF viewer.
While you can format the PDF to be A5 size (148 x 210 mm), the final output still depends on the recipient's printer configuration. If their printer is loaded with A4 paper and set to automatically scale to fit the paper, it will likely print the A5 document on A4 paper.
To ensure the best result, advise your recipients to load A5 paper into their printer, select 'Actual Size' in their print settings, and explicitly choose A5 in the printer properties.
Launch your preferred PDF editing software and open the document you wish to resize.
Navigate to the 'Page', 'Edit', or 'Print Production' menu, depending on your software.
Select 'Page Size' or 'Crop Pages' and choose 'A5' from the dropdown menu, or manually enter the custom dimensions for A5 (148 x 210 mm).
Click 'File' and 'Save' to apply the changes. The PDF itself is now formatted to A5 dimensions.

Frequently Asked Questions
Why does my A5 PDF print on A4 paper?
Printers typically default to the paper size loaded in their primary tray (usually A4 or Letter) and may automatically scale the document to fit that paper. To fix this, you must explicitly select 'A5' in the printer properties before hitting print.
Can I embed a print script in my PDF to force A5 printing?
While JavaScript can be embedded in PDFs to trigger the print dialog box automatically upon opening, it cannot force the recipient's printer hardware to switch paper trays or override their default paper size settings.
What are the exact dimensions of A5 paper?
A5 paper measures 148 x 210 millimeters, or 5.83 x 8.27 inches. It is exactly half the size of a standard A4 sheet.
