A hallway (also passage, passageway, corridor or hall) is an interior space in a building that is used to connect other rooms.
[1] Hallways must be sufficiently wide to ensure buildings can be evacuated during a fire, and to allow people in wheelchairs to navigate them.
The minimum width of a hallway is governed by building codes.
Minimum widths in residences are 36 inches (910 mm) in the United States.
[2] Hallways are wider in higher-traffic settings, such as schools[3] and hospitals.
