Fix Acrobat Printing to Letter Instead of Actual PDF Page Size
Question details
The user wants to print a PDF in its actual custom dimensions, but the printer outputs the document on standard Letter-sized paper.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Printing a PDF document that has a specific or custom page size that differs from the default Letter paper size.
- Observed behavior
- Acrobat ignores the 'Choose paper source by PDF page size' option, and the printer driver forces the output onto Letter paper.
Ensure your printer physically supports the requested paper size, the correct paper is loaded in the tray, and you have administrative rights to modify printer driver settings.
Align Acrobat Print Dialog and Printer Properties
Adjust settings within Acrobat and the printer driver to ensure they both agree on the actual document size instead of defaulting to Letter.
The 'Choose paper source by PDF page size' option in Acrobat cannot override a printer driver that is locked to Letter size. Both Acrobat and your specific printer preferences must be configured to allow custom or actual sizes.
Open your document in Adobe Acrobat, press Ctrl+P to open the Print dialog, and under the 'Page Sizing & Handling' section, select 'Actual Size'.
Check the box next to 'Choose paper source by PDF page size' in the Acrobat print dialog.
Click the 'Properties' or 'Preferences' button next to your selected printer name at the top of the dialog.
Navigate through your printer driver tabs (often under Paper/Quality or Advanced) and ensure that 'Fit to Page', 'Scaling', or default 'Letter' settings are turned off. Confirm the required paper size and tray are selected or set to 'Auto Select'.

Add a Custom Paper Size in Windows
If your PDF dimensions are not available in the printer driver by default, you must create a custom paper size at the system level.

Frequently Asked Questions
Why does my printer default to Letter size for every PDF?
Most printer drivers sold in North America are factory-configured to default to Letter size. If the exact PDF dimensions are not pre-programmed in the printer's preferences, the driver overrides the software and falls back to this default.
Does the 'Fit' option scale my document to Letter?
Yes. If your default printer paper size is set to Letter, selecting 'Fit' in the print dialog will automatically scale your custom-sized PDF up or down to fit neatly onto a standard Letter page.
What if my printer physically cannot support the PDF page size?
If the physical printer trays cannot accommodate the requested paper size (for example, trying to print an A3 document on an A4-only printer), you must either use the 'Fit' option to shrink it to supported paper or print the document in tiles.
Will updating my printer driver fix paper size issues?
It can. Manufacturers often release updated drivers that include expanded lists of supported paper sizes and better communication protocols with modern PDF software. Downloading the latest driver from the manufacturer's website is recommended.
