List the dimensions of each page of a PDF
Import a PDF to display the width and height of each of its pages, in points and millimeters.
How it works
A PDF assembled from several sources (scans, Word exports, screenshots) can contain pages of different sizes without this being obvious at first glance in a reader. This tool reads the effective size of each page (its MediaBox, accounting for inheritance from the document's tree) and displays it in PDF points and millimeters, making it easy to quickly spot a page with the wrong format before printing.
Why are the dimensions in "points"?
The point is the native unit of the PDF format (72 points = 1 inch = 25.4 mm). An A4 page thus measures about 595 x 842 points, and a US Letter page about 612 x 792 points. The tool also displays the millimeter equivalent to make it easier to read.
What should I do if I spot a page with the wrong format?
Use our PDF size normalization tool to resize all pages to a common target format (A4 or Letter, for example) before printing or archiving.
100% local processing: the analysis happens entirely in your browser via WebAssembly — your PDF is never sent to a server.
