Inspect Page Dimensions - Free Online Browser Tool

View exact width, height, and orientation of all pages in points & inches.

Print problems are frequently dimension problems: a page that is 8.27 × 11.69 inches on Letter paper, or a slide that is not a standard ratio. This tool reports the exact width, height and orientation of every page in points and inches, so you know precisely what you are working with.

How to Use the Inspect Page Dimensions Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the PDF

    Drop in the document and every page’s box is measured in points and inches.

  2. Read every page’s dimensions

    Width and height are reported per page in points and inches, with portrait or landscape identified.

  3. Spot the outliers

    Pages that differ from the majority are the ones causing unexpected print scaling — they are easy to identify in the list.

  4. Normalise if needed

    Take the dimensions to Resize Canvas or Standardize Page Sizes to put every page on the same sheet.

Frequently Asked Questions

What is the difference between points and inches?

A PDF works in PostScript points, where 72 points make one inch. That is the unit every PDF specification and every print requirement uses.

What are the standard sizes?

A4 is 595 × 842 points, US Letter is 612 × 792 points and US Legal is 612 × 1008 points. Any page not matching one of those is non-standard.

Why do my pages print with big white margins?

Almost always because the page dimensions do not match the paper you are printing on. Check them here, then normalise the pages.

Does the reported size account for rotation?

The measurement is the physical page box. A page rotated 90 degrees still has the same dimensions — its content is simply oriented differently on that sheet.

Can I measure a single page rather than the whole document?

Yes, the per-page listing shows exactly which page has which dimensions, so a single outlier can be identified and dealt with on its own.
