Set the size and create your PDF
Aspect ratio stays locked: changing one dimension adjusts the other.
Your PDF is ready
Download PDF- In the print dialog choose “Actual size” or “100%”: “Fit to page” changes the centimetres.
- Choose A4 paper and the same orientation (portrait or landscape) as the PDF.
- Check the 50 mm line in the PDF with a ruler before trimming anything.
For posters: follow the rows and columns, trim along the dashed lines and glue the repeated area. Crop marks and page numbers guide you.
How it works
Poster mode splits your image into a grid of A4 sheets. You choose the final centimetres: 60 × 90 cm is 9 sheets, an A3 is 4, and the preview shows rows and columns before anything is created. Each sheet carries an overlap that repeats a strip of the image, dashed trim marks and a row-and-column number so you can assemble the poster without guessing.
Everything happens in the browser: the image is not uploaded anywhere and the PDF is generated on your device. That is why it works the same for personal photos and work documents, and why the maximum size depends on your device memory, not on any server.
What it is for
Event posters
A 60 × 90 cm poster for a party, a gig or a garage sale comes out of a home printer in 9 sheets.
Classroom maps and murals
Giant maps, timelines and group murals: students glue the sheets and the result covers the whole wall.
Large-format photos
That panoramic holiday photo can fill the hallway wall: start from the highest-resolution version you have.
Before you print
- Scale at 100% or “actual size”, never “fit to page”.
- A4 paper selected on the printer, with the same orientation as the PDF.
- Normal or high print quality: draft mode can lighten thin lines.
- First test on plain paper; photo paper only once the size is right.
- Verify it with the calibration sheet: print it and measure the 10 cm square with a ruler.
Frequently asked questions
How do I join the sheets?
Assemble row by row: trim the edge of each sheet along the dashed line, lay the repeated strip (overlap) over the neighbouring sheet and glue. The row and column numbers on the bottom strip tell you where each sheet goes. Tape on the back or a glue stick both work well.
How many pixels does a poster need?
For a sharp result, about 118 pixels per centimetre (300 DPI); for a poster viewed at a distance, 60 px/cm is enough. A 90 cm tall poster asks for 5,400 to 10,600 vertical pixels. If the image is small, a smaller poster will look better than a large blurry one.
Can I change the overlap?
Yes: the Overlap field accepts 0 to 20 mm. With 5 mm (the default) the seams are barely visible and gluing is easy. Setting it to 0 saves a little paper but makes assembly harder: any misalignment leaves a white line.
How much paper and ink does it use?
A 60 × 90 cm poster is 9 A4 sheets. Dark areas use more ink; if the poster is temporary, the printer’s draft mode saves a fair amount. Printing 2-3 sheets first to check the size avoids surprises.
