Most pre-defined image locations on World Anvil don't have minimum or maximum sizes, but they are designed with specific sizes and aspect ratios in mind.
In the following table, the recommended size refers to the minimum size to avoid pixelated/blurry images. The recommended aspect ratio refers to the general ratio for the image to look good; a different ratio will cause the image to be cropped in some cases, and stretched in others.
