Sheets for common map sizes
These counts use a 0.25 inch printer margin and a 0.5 inch overlap. The tool above shows the exact numbers for your picture.
| Poster size | Letter, landscape | Tabloid, landscape |
|---|---|---|
| 24 x 18 in | 3 x 3 (9 sheets) | 2 x 2 (4 sheets) |
| 36 x 24 in | 4 x 4 (16 sheets) | 3 x 3 (9 sheets) |
| 48 x 36 in | 5 x 5 (25 sheets) | 3 x 4 (12 sheets) |
Start with a sharp source
Export the map as a PNG at a high resolution, or take a screenshot at the largest zoom that fits your screen. For a 36 inch wide map, aim for at least 3600 pixels across. That is 100 dpi, which keeps most text readable. Text smaller than about 10 points on the printed map may blur.
Use more overlap on detailed maps
A larger overlap, such as 0.75 inch, gives you more room to match roads and borders. The cost is a few more sheets. Set it with the overlap field and watch the sheet count.
Uses
- Tabletop role-playing maps.
- Floor plans for a renovation or a party layout.
- A trail or route map for a group.
- A world map for a classroom.
Print at actual size
In the print dialog, choose 100% or Actual size. Do not choose Fit to page. That setting shrinks every tile, and the pieces will not line up. Print the test page first and measure it.
Questions
Will the seams break roads and text?
Seams are always visible, but the overlap lets you match lines when you glue. The page labels and cut marks show which edges to line up.
Can I print a map from a PDF?
Convert one page of the PDF to a PNG or JPG first. The tool takes image files, not PDFs.
What is the best paper size?
Use the largest your printer handles. Fewer sheets mean fewer seams. If the printer takes Tabloid (11 x 17), use it.
