How large can the final poster be?

The poster size depends on your tile grid and paper size. A 3x3 grid on A4 paper produces a poster approximately 89cm x 63cm (about 35x25 inches). A 4x4 grid reaches approximately 119cm x 84cm. Custom grids can go even larger.

How do I assemble the tiles?

Print all tiles, then arrange them according to the preview layout. The overlap margins give you a zone where adjacent tiles share the same content, making alignment easy. Crop marks indicate where to trim. Use tape or adhesive on the back to join tiles.

Will it work for architectural drawings?

Yes. Vector-based PDF content (like CAD exports and technical drawings) remains perfectly sharp regardless of the poster size. The tiles preserve the original vector quality so lines and text are crisp at full scale.

Can I set custom overlap margins?

Yes. You can set the overlap width to match your assembly method. Wider overlaps make alignment easier at the cost of using more paper. The overlap zone shows the same content on adjacent tiles for precise matching.
