About this tool

About PDF Page Size Viewer

PDF Page Size Viewer lists the size of every page in a PDF in points, inches and millimetres, together with orientation, rotation and the closest standard paper size such as A4 or Letter. It flags documents with mixed page sizes and rotated pages, and exports the table as a report or CSV.

Unexpected page sizes cause printing problems, odd margins and layout issues when documents are merged. Seeing every page’s size at a glance makes these problems easy to find.
