About the PDF Page Size Checker
Printers and publishers reject files with the wrong paper size. This checker lists every page's dimensions, identifies standard sizes such as A4, US Letter, Legal and A3, and flags documents that mix page sizes — all without uploading the file.
How to use it
- Drop a PDF.
- Review the table of page sizes.
- Look for “mixed page sizes” before sending to print.
Good to know
- Sizes reflect the visible (rotated) page as viewers show it.
- PDF points are 1/72 inch.
