Hi Sara,

Thanks for reaching out to us!

If you just create your Shape Collage with the default settings, it will create a file that is 2880 x 2880 pixels. This is large enough to print at 24cm x 24cm (at 300dpi), so is definitely large enough for 20cm x 20cm.

Please let us know if you have any questions!

Regards – The Ribbet Team
