Gotta say, the max room size being 3 might seem small, but it's perfect for keeping things manageable. Trust me, once you've got a couple of fully upgraded 3-wide rooms, you'll see your vault thriving like never before.
The max room size in Fallout Shelter is 3 units wide. You can start with a single unit and then upgrade by connecting two more units of the same type. Makes your vault super efficient and your dwellers happier than a radroach in a nuclear winter!
