What the result means

PDF page size is stored in points (72 points = 1 inch). A page that matches Letter within two points is labelled Letter even if it is rotated. Mixed sizes are listed so you can see which pages differ.

Common mistakes

  • Assuming on-screen zoom equals physical page size.
  • Ignoring a Rotate entry that swaps displayed width and height.
  • Treating CropBox as the trim size when TrimBox is missing.

Frequently asked questions

How do you recognise Letter, Legal, or A4?

Each page’s displayed MediaBox is compared with a named-size table using a 2-point (about 0.7 mm) tolerance. Landscape Letter still matches Letter.

What is the difference between MediaBox and TrimBox?

MediaBox is the full page canvas. TrimBox, when present, is the intended finished size after trimming. CropBox can hide parts of the media box on screen.

If BleedBox exists, do I have real bleed?

Not necessarily. Real bleed requires artwork to extend beyond the trim edge. A box can exist without any ink in that area. Extra empty margin is not real bleed.

Can you tell me every font is embedded?

Only when font dictionaries include a FontDescriptor with a FontFile stream. If that cannot be read, the report says Unknown instead of guessing.
