Printing A2

A2 needs a large-format printer or a print shop. To proof at home, print at 50%: an A2 design scaled to 50% fits exactly on A4, because each step in the A series halves the area.

Questions

How big is an A2 poster in pixels?

4961 × 7016 px at 300 dpi. For a poster viewed from a distance, 150 dpi (2480 × 3508 px) is usually enough.

Is A2 related to the A2 envelope?

No. The US “A2” invitation envelope is 4 3/8 × 5 3/4 in; the name is unrelated to ISO A2 paper.
