Sobre esta ferramenta
Mixed page sizes are the reason a print job comes back wrong. A document assembled from several sources can be A4 throughout except for two Letter pages and one landscape insert, and nothing on screen tells you that.
This lists every page with its exact dimensions in millimetres, inches or points, its orientation, and the standard size it corresponds to where there is one. Pages that differ from the document majority are highlighted, which is the fastest way to find the odd ones in a 200-page file.
Useful before sending anything to a commercial printer, and useful for diagnosing why a document that looks fine on screen prints with unexpected margins.

Perguntas frequentes
What is a PDF point?
One 72nd of an inch, the native PDF unit. A4 is 595 by 842 points; Letter is 612 by 792.
Why do my pages differ by a fraction of a millimetre?
Rounding between points and millimetres. Differences under half a millimetre are not real inconsistencies.
How do I fix mixed sizes?
Use Fix Page Size to standardise the whole document onto one page size.
Does it report crop boxes as well as page size?
The visible page dimensions are reported, which is what a printer works from.
