- Product
- Adobe Acrobat / PDF Editors
- Device & OS
- not provided
- Scenario
- Creating a new blank PDF document from scratch with a specific paper size.
- Observed behavior
- The standard 'Create Blank Page' command in tools like Acrobat does not provide a page-size preference or dialog box to choose A4 dimensions.
Determine whether you are creating a brand new blank PDF document or attempting to insert a blank A4 page into an already existing PDF, as the recommended workflow differs for each.
Create an A4 Document in a Word Processor and Export to PDF
Since some PDF editors lack a direct sizing tool for new blank pages, the most reliable workaround is to generate a blank A4 page in a word processor and save it as a PDF.
This method guarantees that the page dimensions are exactly matched to the A4 standard without needing complex PDF utility plugins.
Launch your preferred word processing software, such as Microsoft Word or WPS Writer.
Navigate to the 'Page Layout' or 'Page Setup' tab on the ribbon. Click on 'Size' and select 'A4' from the dropdown menu.
Leave the document completely blank. Go to 'File' > 'Export to PDF' (or 'Save As' and select PDF as the file format), then save the file to your computer.

Use a Dedicated PDF Utility or Add-on
Use specialized third-party PDF utilities or add-on scripts that extend your PDF editor's capabilities to generate custom-sized blank pages.
Use WPS Office to Create A4 Blank PDFs
WPS Office provides an integrated suite where you can effortlessly create a perfectly sized A4 blank document in WPS Writer and instantly convert it to a high-quality PDF in just a few clicks.
- 1. Create a new document: Open WPS Office and select 'Docs' to create a new blank Word document.
- 2. Change page size to A4: Navigate to the 'Page' tab on the top ribbon, click 'Size', and select 'A4'.
- 3. Export as PDF: Click 'Menu' in the top-left corner, then choose 'Export to PDF'.
- 4. Save the file: Choose your desired save location and click 'Export'. You now have a perfectly sized blank A4 PDF.

Frequently Asked Questions
Can I change the page size of an existing PDF to A4?
Yes, you can resize an existing PDF to A4 by using the 'Print' function. Select a virtual PDF printer (like 'Microsoft Print to PDF' or 'WPS PDF'), click 'Properties', set the paper size to A4, and 'Print' it to save a new resized PDF file.
Why doesn't Adobe Acrobat let me choose the size for a blank page?
Acrobat's default 'Create Blank Page' tool automatically generates a page using a standard predefined size (often Letter or the dimensions of the last created document) and intentionally skips the page-size prompt to speed up the process.
What are the exact dimensions of an A4 page?
The standard A4 paper size measures 210 x 297 millimeters, which is approximately 8.27 x 11.69 inches.
