Book & Print Tools › PDF page size checker

Printers reject PDFs whose page size does not match the order. Checking the size yourself takes a few seconds and can save a day.

Choose a PDF. The tool reads it in your browser with the open source pdf.js library and reports the page count, the size of the first page in inches and millimetres, the TrimBox and BleedBox if the file defines them, and the fonts used. Your file is not uploaded.

If the sizes do not match your order, fix them in your layout software rather than scaling the PDF. A file with a bleed box should be larger than the trim size by the bleed on every side. Fonts that are not embedded can be replaced by the printer, so look at that line too.

How to use it

1. Choose a PDF file.
2. Compare the page size with the size you ordered.
3. Fix any differences in your layout software.

Worked example

A 6 × 9 in print PDF with 3 mm bleed shows a page of about 6.24 × 9.24 in.
