We recommend that all images are 130 dpi (dots per inch) or higher, in order for them to look good when printed. This is a piece of cake for modern mobile phone cameras.
This means the following resolution or higher:
Mini: 827x1118 pixels
Square: 1157x1118 pixels
Wide: 1654x 1118 pixels
Classic (A5): 1157x1614 pixels
Big (A4): 1654x2339 pixels
Wall Planner: 2362x2362 pixels
We want your printed picture to be as close as possible to the preview on our website but, occasionally, the print version can differ by a few millimeters. For that reason, make sure to keep important bits at a safe distance from the edge!
