Paper size guide with millimeter, inch and pixel dimensions

Using paper dimensions without introducing scaling

Match the document canvas, browser paper selection, printer driver, tray, and loaded media. A correct A4 document can still print incorrectly when the driver expects Letter paper and silently fits one format inside the other.

Pixel dimensions depend on physical size and PPI

Pixels equal inches multiplied by target PPI. Add bleed separately for commercial trimming, and confirm the print provider's required bleed and color workflow before creating production files.
