- Product
- Adobe Scan / PDF Viewer
- Device & OS
- not provided
- Scenario
- Printing PDF documents that were scanned using the Adobe Scan application.
- Observed behavior
- Scanned documents are printing at a smaller scale than the original physical document due to automatic margin scaling.
Before printing, ensure that the physical paper loaded in your printer exactly matches the standard dimensions of your scanned document (such as A4 or Letter) to prevent hardware-level scaling.
Adjust Print Scaling to Actual Size
Change your PDF viewer's print settings to output the document at 100% scale instead of shrinking it to fit within default margins.
By default, most PDF readers shrink documents to ensure no content is cut off by the printer's unprintable margins. Changing this setting forces the printer to output the exact scanned dimensions.
Open your scanned PDF document in Acrobat or your preferred PDF viewer, then go to File and select Print.
Locate the 'Page Sizing & Handling' section in the print dialog box. Select 'Actual Size' or choose 'Custom Scale' and set it to 100%. Do not use 'Fit', 'Shrink', or 'Scale to Printable Area'.
Ensure the selected paper size matches your original document's dimensions, then click Print to generate the correctly sized output.

Match Printer Preferences to Document Properties
Ensure that your printer's software settings match the digital page size to prevent the printer driver from automatically resizing the output.

Frequently Asked Questions
Why does my printer automatically shrink PDF pages?
Most PDF viewers and printers default to a setting called 'Fit to Printable Area'. This shrinks the document slightly to ensure that text or images near the edges aren't cut off by the printer's physical hardware margins.
How do I check the original page size of my scanned PDF?
In your PDF viewer, you can usually check this by going to File > Properties or Document Properties (often accessible by pressing Ctrl+D). The exact page dimensions will be listed in inches or millimeters.
Can I set 'Actual Size' as the permanent default printing option?
This depends on your specific PDF software and printer driver. In most cases, you must select 'Actual Size' each time you print. However, you can check your computer's 'Devices and Printers' settings to see if your printer driver allows you to set a permanent 100% scale default.
