Print an A3 poster at home
Tile A3 (11.7 × 16.5 in) — a small poster or a large diagram — across the paper you already have.
A A3 poster is 11.7 × 16.5 in (297 × 420 mm). Most home printers can't print that on one sheet, so GrafixManager tiles it across ordinary Letter or A4 pages you tape together — at the exact real-world size. Print at 100% / Actual Size, measure the calibration square on page one, then trim and tape the sheets.
How many sheets?
A3 is exactly two A4 sheets by area; with an overlap it tiles across a small handful of pages.

Questions
Can I print A3 on a normal home printer?
Yes. Your printer only prints one Letter or A4 sheet at a time — GrafixManager splits the A3 design across as many sheets as needed, with alignment marks so they line up.
Will the finished poster really measure 11.7 × 16.5 in?
Yes, if you print at 100% / Actual Size (never "Fit to Page"). Measure the calibration square on page one to confirm the scale before printing the rest.
