What is the minimum length of a level landing required for an exit door swing?

The minimum length of a level landing required for an exit door swing is 60 inches. This dimension ensures that there is adequate space for the door to swing open fully without obstruction and allows for safe egress in case of an emergency. A landing of 60 inches provides sufficient room for individuals to comfortably enter and exit through the door, which is especially important in buildings that may experience high foot traffic.

In the context of building codes and regulations, the requirement for a minimum landing size helps to accommodate people with disabilities and promotes overall accessibility within the built environment. The standard length also considers safety factors related to the operation of doors, allowing enough clearance to avoid accidents and ensuring smooth transitions in and out of spaces.

For instance, if the landing were smaller, such as 48 inches, it might not provide adequate space for people with mobility assistance devices, which could impede their ability to use the door safely and effectively. Therefore, 60 inches is the critical dimension that supports both safety and accessibility.
