How big are Lands? They're described as planets but are they really Earth-sized? I get the impression they're actually very small, given that a housetower isn't invisibly thin compared to the whole planet, and because (I assume) a player is probably expected to explore the whole Land to fully complete their Quest. Similarly, Prospit and Derse look the same size as Lands but the Derse chain doesn't look incredibly huge next to Rose and Dave. Is there a canon answer besides just these comparisons?

I have done SEVERAL checks of the sizes, and what I’ve come to find out is that a) They’re definitely smaller than an actual planet, and b) Hussie gives no fucks about the actual size of the Lands.

Seriously though, Hussie’s not the best when it comes to distances and sizes, and Derse has actually been shown to be both the same size of one of the Lands, AND also a bit smaller, so it’s just. Smaller than the Earth, probably smaller than the Moon, and very much inconsistent depending on what you take as a reference.
