PDF Page Size Checker
Upload a PDF to see each page's size, orientation, and whether they're all consistent — nothing is changed or downloaded, this is a read-only check.

| Page | Size (pt) | Approx. | Orientation |

Upload a PDF and this tool reads every page's exact size in points, converts it to the nearest common paper size (A4, Letter, etc.), and flags whether all pages share the same size and orientation. See the A4 vs Letter guide for why this actually matters when printing.
What this checks
PDF Page Size Checker FAQs
Why do page sizes matter?
Mixed page sizes in one PDF can cause printing issues or look inconsistent when viewed. This tool helps you spot that before you send or print a document.
Does this change my PDF?
No — this is read-only. It only reads and displays information; no file is modified or downloaded.
What counts as "A4" or "Letter"?
Sizes are matched to the nearest standard paper size within a small tolerance, since PDFs can have tiny rounding differences in their stored dimensions.
Is my file uploaded anywhere?
No — everything runs in your browser using JavaScript.
