Questions

How many pixels is 4500 × 5400 (print on demand)?

4,500 × 5,400, which is 24.3 megapixels in a 5:6 shape.

What scale takes a 1080p image to 4500 × 5400 (print on demand)?

4×, then a small resize. 1920 × 1080 becomes 4,320 × 7,680 at 4×, and resizing it 1.04× gives exactly 4,500 × 5,400.

Will an upscaled image look like a native 4500 × 5400 (print on demand) image?

It will look sharp at normal viewing distance, with clean edges and plausible texture. The model invents detail that fits, so tiny text or faces far from the camera will not match a true high-resolution original.

What if my image has a different shape?

Crop to 5:6 first with the crop tool, then upscale. Otherwise one side lands on the target and the other side overshoots or falls short.
