A3 Copy Paper

A3 copy paper is the everyday sheet at double A4 size — plans, spreadsheets, artwork proofs and anything that loses detail when shrunk. Check your printer tray takes A3 before ordering; many desktop machines top out at A4.

An 80gsm sheet handles double-sided printing without show-through, which is where most A3 jobs end up. See A3 coloured papers, A4 copy paper and all copy paper.
