How to check a PDF really is C4 Envelope
- Open the file in PdfRuler. It runs in your browser and nothing is uploaded.
- Read the page size in the status bar and set the unit to mm. It should read 229 x 324 mm.
- A PDF that says 649 x 918 pt is the same sheet rounded to whole points, so mm may differ by a fraction. That is normal; see what a PDF point is.
