What is the difference between A3 & A4? #asktheexpert


"A" Series paper sizes are the standard method for sizing paper throughout most of the world. This method uses the Metric system.


Because the U.S., Canada, and parts of Mexico use the imperial method, our standard paper sizes are measured in inches.

  • A3 Max size = 11" X 17" (Legal paper)

  • A4 Max size = 8.5" X 14" (Ledger Paper)
