What is the minimum size requirement for a stair landing?

The minimum size requirement for a stair landing is 4 feet by 4 feet. This dimension is specified to provide enough space for users to safely transition between stairs and another surface, such as a floor or walkway. A landing of this size allows individuals to step off the stairs and pause without feeling crowded, which is particularly important for safety and accessibility.

A landing that is too small could pose risks, such as the potential for people to misstep or lose their balance while transitioning, especially in emergency situations or when carrying objects. The 4’ by 4’ requirement ensures that there is adequate room for individuals to maneuver safely and comfortably, making it a standard in building codes and regulations.
