Why 30×40 cm Cuts Things Off
30×40 cm is 3:4, the shape of nearly every phone photo, so phone pictures fill it untrimmed. Camera photos are 2:3 and lose about a ninth of their length. It's close to 12×16 inches, the same shape, but not identical: a 12×16 print is 30.5×40.6 cm and won't sit in a 30×40 frame without trimming. At 300 DPI it needs 3,543×4,724 pixels; we deliver about 3,464×4,619, essentially full resolution.
Instead of trimming your photo down to the shape, we generate more of the scene around it until it fits — and sharpen the whole image in the same pass.
