A green check means your image matches that spec exactly. Platforms generally accept other sizes too — this is a quick reference, not a hard requirement.

FAQ
- What if my image doesn't match any spec exactly?
- That's usually fine — most platforms will crop or letterbox images that don't match exactly, though matching the spec avoids unwanted cropping of important content.
