What is the required minimum width for landings at stairway runs?

The correct minimum width for landings at stairway runs is specified to ensure safety and accessibility for users, particularly in emergency situations. A landing serves as a space where individuals can pause and change direction or make their way safely to the next set of stairs or an adjacent area.

In many building codes, including those applicable to Montana, the required minimum width of landings is often set to accommodate the average width of individuals, the movement of objects, and the potential for two-way traffic. A minimum width of 60 square inches is deemed sufficient to provide appropriate space for these needs.

By specifying 60 square inches, it allows for both safety and compliance with regulations that require sufficient space for maneuverability. This minimizes the risk of accidents such as falls, especially in high-traffic areas or during emergencies when swift evacuation is necessary. The other options do not align with the standard requirements, reflecting either excessively larger dimensions or incorrect units entirely, which are not practical for stair landings.
