How long can a room divider be?
On One Hand: The Length of the RoomThe room divider should be the length of the room to block out all sound and to prevent things like dust and hot air from passing between the two rooms. Install at least one doorway within the partition and perhaps some windows or plain openings to add some transparency to the room divider.On the Other: Halfway Is FineA room divider is a flexible design element that does not need to extend across the whole length of the room. It can actually be a half wall with a height of several feet or a full wall that only fills part of the room.Bottom LineA room divider can be as long or as short as is needed for the room.
