While I agree that the Kingdoms aren't the size of the continent they're on. However, Atlas's only known settlements are Atlas and Mantle, indicating that Atlas is a small kingdom compared to the other three.

However the kingdoms are not city-states. Vale also has Patch and several other cities on the coast. Mistral has Kuchinashi, Wind Path, and Argus. It's even mentioned that Mistral is the biggest of the four kingdoms territory wise.
