A3 is the size for posters, plans, wall charts and anything meant to be read from across a room. Micron matters more at this size than at A4, because a large sheet at 80 micron will flop in the hand — 125 micron and up keeps a poster rigid enough to pin or stand. Check your machine takes A3 before ordering, since many desktop units stop at A4. See A3 laminators or the full pouch range.
