What does a print ratio mean?

A ratio is the shape of the artwork. It is not the final size. A 2:3 file stays the same shape whether it is printed small or large, while a 4:5 file is a slightly wider rectangle.

If you choose a frame that has a different shape from the file, part of the artwork may be cropped or you may need a border or mat board.

How to choose the right file

Start with the frame or print size you want, then pick the file with the matching shape. If you already own an A3 frame, use the ISO-A file. If you want a 40x60 cm poster, use the 2:3 file.

Avoid uploading one random file and letting the printer auto-crop. Preview the crop before checkout, and choose "fit" rather than "fill" if you want to preserve the whole artwork.
