- Device & OS
- not provided
- Scenario
- Preparing a PDF document for business card printing by customizing the page size.
- Observed behavior
- When entering the custom dimensions of 87 mm x 57 mm, the values reset to default, preventing the page (especially the back page) from being correctly resized.
Before resizing your PDF, ensure the document is not password-protected or restricted against editing, as this can cause custom dimension values to revert automatically.
Use the Scale Pages Fixup in Preflight
Utilize the Preflight tool to force precise page scaling and bypass basic crop tool restrictions.
Standard cropping tools sometimes restrict dimensions based on the original document's media box. Using a dedicated Preflight scaling fixup forces the PDF to adopt your exact requested dimensions.
Open your PDF document in your advanced PDF editor. Navigate to 'Tools', select 'Print Production', and then click on 'Preflight'.
Search for the 'Scale Pages' fixup profile within the Preflight dialog box.
Edit or duplicate the profile to set your exact custom dimensions to 87 mm for the width and 57 mm for the height.
Apply the fixup and specify the page range (e.g., just the back page or the entire document) to finalize the resizing without the values resetting.

Remove PDF Security Restrictions
If dimensions keep resetting, document restrictions might be blocking formatting changes.

Frequently Asked Questions
Why do my custom PDF dimensions keep resetting?
This usually happens if the document has security restrictions enabled, or if the PDF editor's crop box settings conflict with the predefined media box. Removing security or using advanced scaling tools can resolve this.
What is the standard size for a business card in mm?
The standard business card size is typically 85 mm x 55 mm in Europe or 89 mm x 51 mm in the US. However, 87 mm x 57 mm is often used by printers to include a bleed area for edge-to-edge printing.
Can I resize just one page of a multi-page PDF?
Yes, professional PDF editors allow you to specify a page range when adjusting page sizes or applying scaling tools. You can choose to apply custom dimensions exclusively to the front or back page.
