How big can the rooms get in Fallout Shelter?
In Fallout Shelter, rooms can initially start small but you can upgrade them up to three times. Each upgrade expands the room, allowing you to merge up to three of the same type of rooms placed next to each other horizontally. So, the biggest a room can get is 3 merged and fully upgraded segments wide, making it a super-efficient space for your Dwellers to work in!

Rooms max out at 3 units wide after you upgrade and merge them. Anything beyond that is just wishful thinking in the wasteland.
I've been playing Fallout Shelter since it came out, and trust me, managing your space wisely by merging and upgrading rooms to their max size (3 segments wide) is key to vault happiness. Plus, those fully upgraded rooms look pretty cool.
