See the effective print DPI before you print, so you know if the result will be sharp.

Frequently asked questions

How do I join the pages together?

In "Overlap & glue" mode, each page includes a duplicated strip along shared edges — trim nothing, just line up the grey-tinted overlap zones and glue there. In "Trim & butt-join" mode, cut along the printed crop marks on each page, then butt the trimmed edges together.

What image size do I need?

The tool shows an effective DPI and quality rating for your chosen poster size. Aim for at least 150 DPI for a good result — if it's rated "blurry", use a larger source image or reduce the number of pages.

Does it work with A3?

Yes — A4, A3, Letter, Legal, and Tabloid are all supported, in portrait or landscape, with an adjustable printer margin.
