What is the minimum width required for a stairway?

The minimum width required for a stairway is primarily determined by building codes that ensure safety and accessibility. A standard minimum width for stairways is often set at 44 inches, allowing sufficient space for individuals to navigate stairs safely, especially in public or commercial buildings. This width accommodates the passage of more than one person at a time and is particularly important in emergency situations where quick evacuation may be necessary.

While some residential buildings may have different requirements, 44 inches is commonly recognized as the standard for public spaces to enhance safety and comfort. This width helps prevent bottlenecks during busy times and ensures that individuals, including those who may require assistance or mobility devices, can use the stairway effectively. The choice of 44 inches reflects an understanding of these safety and accessibility needs.
