Questions
What size is an A3 mat?
420 × 297 mm (16.54 × 11.69 in), its cut size. At 300 DPI that is 4961 × 3508 px.
How big should the art for an A3 mat be?
426 × 303 mm (16.77 × 11.93 in), or 5031 × 3579 px at 300 DPI: the cut size plus 3 mm of bleed on every side, so a cut that is slightly off leaves no white edge. Keep text and anything important inside the 414 × 291 mm safe area.
How many fit on a sheet of paper?
It is bigger than a sheet of Letter or A4, so the PDF template tiles it: 4 pages of Letter or 4 of A4, after an assembly map, overlapping so you can trim and tape them.
