PDF measures length internally in points (1 pt = 1/72 inch). Both pt and millimeters are shown here, so you can tell whether the paper is A4 or something else.

When to use it

  • Someone sent you a PDF and you want to know the page count, whether it's A4 and whether any landscape pages slipped in
  • Before printing or merging, when you need to confirm all pages share the same size

When not to

  • You just want to read it — a PDF reader opens faster
  • You need to change page size, extract images or list fonts — this tool is read-only
Limits and privacy

Everything runs locally in your browser; the file is never uploaded or stored. Read-only: no editing, no text extraction, no font analysis; encrypted PDFs can't be parsed; very long documents use more memory.

Frequently asked

Can I see the size of every page?

Yes. Sizes are grouped and counted, e.g. “595×842 pt × 12 pages; 842×595 pt × 2 pages”, so landscape pages stand out immediately. Rotation is counted separately.

Why does it say the paper is custom?

Paper is matched against standard sizes (A4 595×842 pt, A5 420×595 pt, Letter 612×792 pt, A3 842×1191 pt); anything off by more than 2 pt is labelled custom. Scans and design files are often custom.

Does it work on encrypted PDFs?

No. A PDF with an open password cannot be parsed and will error out. Remove the password in the original app first.
