Users are unable to find or select custom paper sizes when attempting to print a document to PDF via system or third-party virtual PDF printers.
- Product
- Print to PDF
- Device & OS
- not provided
- Scenario
- Attempting to print a document to PDF using specific, non-standard page dimensions.
- Observed behavior
- Custom paper size options are completely missing or grayed out from the Print to PDF dialog and printer preferences.
Ensure that your source application allows custom page dimensions and verify that you have administrative privileges to modify system-level printer properties.
Configure Custom Paper Size in Print Server Properties
Creating a new global form in the system's Print Server Properties makes the custom size available to all virtual PDF printers.
Many virtual PDF printers pull available paper sizes directly from the operating system's global print server forms. By defining a new form here, you force the Print to PDF driver to recognize your custom dimensions.
Go to the Start menu, open Settings, and navigate to 'Bluetooth & devices' > 'Printers & scanners'.
Scroll down to the 'Related settings' section and click on 'Print server properties'.
In the Forms tab, check the box that says 'Create a new form'. Enter a recognizable name for your custom paper size in the 'Form name' field.
Under 'Form description (measurements)', enter your exact custom width and height. Click 'Save Form' and then 'OK'.
Restart your source application, open the Print dialog, select your PDF printer, and choose your newly created form from the paper size dropdown.
Add Custom Page Size via Adobe PDF Printer Preferences
If you are specifically using Adobe Acrobat, you can add a custom paper size directly within the Adobe PDF printer settings.
Easily Export to PDF with Custom Paper Sizes in WPS Office
Bypass virtual printer driver limitations completely by using WPS Office's built-in PDF export feature. It natively supports custom paper layouts without requiring complex system configurations.

- 2. Set Custom Page Size: Navigate to the 'Page Layout' tab on the ribbon, click on 'Size', and select 'More Paper Sizes' at the bottom of the dropdown.
- 3. Enter Dimensions: Input your specific custom width and height measurements in the Page Setup dialog box and click 'OK'.
- 4. Export to PDF: Click the 'Menu' button at the top left corner, hover over 'Export to PDF', and configure your preferred export settings.
- 5. Save the File: Click the 'Export' button and choose a destination folder to save your perfectly sized custom PDF document.
Frequently Asked Questions
Why is the 'Custom' paper size option grayed out in my PDF printer settings?
This usually happens due to limitations within the specific virtual printer driver you are using, or because you lack the administrative privileges required to create new print forms on your operating system.
Does Microsoft Print to PDF support custom sizes natively?
Microsoft Print to PDF has a limited set of built-in standard sizes and does not natively offer a user-friendly interface for adding custom sizes. You often have to rely on Print Server Properties or switch to software with built-in PDF export like WPS Office.
Can I save a custom paper size for future Print to PDF tasks?
Yes. By creating a new form via Windows Print Server Properties or saving a custom preset inside the Adobe PDF Printing Preferences, the custom size will be stored permanently for future use.
Why does my document layout change when I select Print to PDF?
If the virtual PDF printer's default paper size (such as A4 or Letter) differs from the original document's page setup, the layout will shift. You must ensure the PDF printer's paper size matches your document's dimensions.
