How to print a 24×36 poster on A4

A 24×36 inch poster is a common US wall size. On A4 paper, a 3×3 portrait grid (9 sheets) lands closest — about 24.8×35.1 inches before margins.

Best-fit vs fewer sheets

3×3 A4 (9 sheets) is the closest practical match to 24×36. An 8-sheet alternative saves paper but produces a smaller poster.

If you need exact inches, slightly crop or letterbox the image in the editor so important content stays inside the tile grid.

Assembly tips for 9-sheet posters

Lay all sheets face-up on a large table before taping. Match labels first, then flip sections to tape from the back.

Work from the center outward to reduce cumulative misalignment across nine joins.

Step by step

  1. Open SmartPrint and set target paper to A4 portrait.
  2. Use a 3×3 grid as the best-fit starting layout for 24×36.
  3. Upload your image and check the preview dimensions.
  4. Export the tiled PDF and print all 9 pages at actual size.
  5. Assemble in row/column order; trim only if using seamless mode.

Pro tips

  • Print page A2 (center) first as a color and margin proof.
  • Use consistent paper stock for every sheet so joins look even.
  • Hang with removable strips if you may reprint later.
