Split Image for Printing

Upload an image and choose how many A4 sheets to place across the poster. The height is calculated from the image proportions, and under the layout you can see the poster size in centimeters and the total sheet count. The result is a single PDF where each page is one sheet of the poster.

How to assemble the poster

Adjacent sheets are printed with a shared overlap strip. On the sheets to the right and below, a dashed line runs along that strip. Cut the sheet edge along the dashed line, place it on the neighboring sheet so the image lines up, and glue them together. At the bottom of each sheet you will find its number, row, column, and a small diagram of the poster with that sheet filled in.

Printer margins

Most printers cannot print right up to the edge of the sheet. A 5 mm margin works for almost all of them; if your printer supports borderless printing, set it to 0. The 10 mm overlap forgives a small misalignment when cutting.

How sharp it will look

The larger the poster, the fewer image dots fall on each inch of paper. The sharpness value is shown under the layout: at 150 dots per inch the poster looks sharp even up close, 100–150 is enough for a wall, and below 100 the blur becomes noticeable.
