PDF pages can differ in size even when they look similar on screen

A document may contain one page that is slightly off A4, or a cover that is a different size from the body. This tool lists every page in pt, mm, and inches so those differences are easier to spot.

A PDF point (pt) is a common PDF length unit; this tool converts using 72 pt = 1 inch.

Rotated pages are reported using the displayed page dimensions

A PDF can store rotation separately from the underlying page dimensions. The tool uses the PDF.js display viewport and also shows the page rotation angle.

If width and height appear reversed, check the Rotation column before assuming the page size is wrong.

For submission work, checking every page is safer than checking only page 1

Mixed page sizes are easy to miss in a normal PDF viewer—for example, an A4 body with one Letter page in the middle.

If the pages need to be standardized, continue with PDF page resizer after checking the current document.

This is not a full bleed or PDF-box preflight

The tool reports displayed page dimensions and rotation. It does not automatically certify TrimBox, BleedBox, bleed allowance, or every print-provider requirement.

For final delivery, compare the result with the printer’s PDF specification.
