How to check a PDF really is A6

  1. Open the file in PdfRuler. It runs in your browser and nothing is uploaded.
  2. Read the page size in the status bar and set the unit to mm. It should read 105 x 148 mm.
  3. A PDF that says 298 x 420 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.

Printing it? Check your printer does not rescale the page with the print at actual size test sheet.
