Poster Printing — Split an Image into Pages

Print a big poster on a normal printer

A home or office printer can only print up to A4 or Letter, but a poster can be far bigger. The trick is tiling: the image is enlarged and split into a grid of pages, each printed on a single sheet, then taped or glued together into one large print. This tool does the splitting and gives you a single multi-page PDF — one sheet per page.

You decide how many sheets wide the poster should be; the height follows automatically so the picture keeps its proportions. Add an overlap so neighbouring sheets share a glue strip, set a small margin for your printer's unprintable border, and you're ready to print at 100%.

How to make a tiled poster

1. Open your image. Drag a photo onto the tool above, choose a file, or paste it. A high-resolution image gives the sharpest poster.
2. Choose how many pages wide. The page opens on the Poster tab with A4. Use the + / − stepper to set the width; the tool shows the resulting grid (e.g. 3×4 sheets) and the finished size in inches.
3. Set overlap and margin. A 10 mm overlap gives a glue strip; the margin matches your printer's border. Pick a background colour for any blank areas.
4. Download and print. Click Download PDF, then print at 100% (turn off 'fit to page'), trim the margins, and assemble the sheets.

Print at 100% — not 'fit to page'

The single most important setting is to print at actual size (100% / no scaling). If your print dialog scales the PDF to fit the page, the tiles won't line up. Choose 'Actual size' or set the scale to 100%, and the overlap strips will match perfectly.
