You'll need a printer that specifically supports A3, as many home inkjets only go up to A4. Check your printer's maximum paper size before ordering if it takes A3, this paper will work fine.

For framing and display, heavier 240–260gsm is best, it stays flat and feels premium at this size. For posters or bulk printing where cost matters more, 180–200gsm does the job well.

Bigger sheets are more prone to flexing and curling, so the extra thickness of 240–260gsm helps them stay flat and rigid. That makes a real difference when a print is framed or mounted, where any waviness would show.

Keep it flat and sealed in its packaging somewhere cool and dry, large sheets show curling and moisture damage more than small ones. Storing it flat rather than upright helps it stay perfectly even, ready for that big print.
