Question details
The user wants to know if the Adobe Acrobat mobile app has an automatic setting to match the print paper size to the PDF document's original dimensions.

- Product
- Adobe Acrobat Mobile App
- Device & OS
- not provided
- Scenario
- Attempting to print a PDF directly from a mobile device and wanting the printer to automatically select the paper tray based on the PDF page size.
- Observed behavior
- The Adobe Acrobat mobile app lacks the 'Choose paper source by PDF page size' feature that is available in the desktop version.
Ensure your mobile device is connected to a wireless printer and that you have checked the default paper settings within your system's mobile print service.
Use Adobe Acrobat Desktop for Advanced Printing
Since the mobile app does not support dynamic paper size matching, use the desktop version of Adobe Acrobat to access the 'Choose paper source by PDF page size' option.
Mobile printing services currently offer limited control over automated hardware tray selection. To accurately match your physical paper to the document's digital dimensions, you must initiate the print job from a desktop computer.
Sync the PDF file from your mobile device to your Mac or Windows computer via cloud storage or file sharing.
Launch Adobe Acrobat on your computer and open the transferred PDF file.
Click on 'File' in the upper-left corner of the menu bar and select 'Print', or use the keyboard shortcut Ctrl+P (Cmd+P on Mac).
In the Print dialog window, locate the 'Page Sizing & Handling' section and check the box labeled 'Choose paper source by PDF page size' or select 'Actual Size'.
Verify your selected printer and click the 'Print' button at the bottom right to begin printing.

Frequently Asked Questions
Can I customize paper size when printing directly from my mobile phone?
Yes, but options are limited. Mobile printing relies on built-in OS services (like Apple AirPrint or Android Default Print Service), which usually allow you to pick standard sizes like Letter or A4 manually, but do not automatically read the PDF's dimensions to switch trays.
Why is 'Choose paper source by PDF page size' missing in mobile apps?
Mobile operating systems handle print spooling via simplified universal drivers. This architecture restricts individual applications from sending complex, automated hardware commands—like dynamic paper tray switching—directly to the printer.
How do I ensure a PDF prints in its actual size without scaling?
To prevent a PDF from shrinking or expanding to fit the paper, open the file in a desktop PDF reader. In the Print dialog box, look for the 'Page Sizing & Handling' section and select 'Actual Size', or set the custom scale value exactly to 100%.
