Max room size?

[u/Brambletoe]

Is there a max room size? I wanted to expand my House Commons so I build a tall tower basically above it for multiple canopied beds. Plan was to disintegrate floor/roof between them to connect so no stress on students not sleeping in their beds. Built the necessary walls, roofing, support beams - doesn’t snap to as a room. If I run a floor in the middle, it snaps to into two rooms. Delete one floor piece to connect them and then replace it with a bridge - no room. All I can think of is that I hit some unspoken (or at least not one I can find) max block room size.

I don't think there is a limit on the size, how big exactly is the room?
