These are the recommended resolutions for the desired aspect ratios with Stable Diffusion XL. You can bookmark this page to use as a quick reference.
SDXL was trained with images of size 1024x1024. Thus, it works best if you generate images of this size. However, if you don't want square images, you can still ask SDXL to generate images of other aspect ratios.
