The PDF Page Size Viewer reads each PDF page width, height, orientation, and standard paper match locally in your browser. It shows size distribution, whether all pages are uniform, and lets you download a JSON report.
Main Features
- Upload one PDF file and analyze it locally.
- View page width and height in pt, mm, or inch.
- Detect common paper sizes such as A series, B series, Letter, Legal, Tabloid, and Executive.
- Summarize unique page sizes and their page numbers.
- Check whether the whole PDF uses one uniform page size.
- Export the complete result as a JSON report.
How To Use
- Choose a PDF from the upload area, or drag the file into it.
- Select the display unit you want to use.
- Click Analyze Page Size.
- Review size distribution and page details on the right.

Use Cases
- Confirm whether a PDF is A4, Letter, or another standard size before printing.
- Check mixed page sizes in scanned documents before submission.
- Verify page dimensions before archiving contracts, invoices, and reports.
- Inspect PDFs after merging files from different sources.
Notes
- Encrypted PDFs may need to be decrypted before analysis.
- Standard paper detection allows a small tolerance for near-standard pages.
- The tool only reads page size definitions and does not modify the original file.
