Why page size matters

Printers, print shops and upload portals often require a specific page size. A single odd page, such as a landscape table or a scanned receipt, can cause printing problems. This tool shows every page so you can spot them.

Sizes are measured from the visible page area (the crop box), which is what viewers show and printers print.

Tip: Found pages of different sizes? Fix PDF Page Size makes them all match.
