What do you call a complete set of steps including rails, from the threshold to the sidewalk?

The terminology for a complete set of steps that includes both the individual risers and the supporting elements, such as handrails, is referred to as a "rise." In the context of stair construction, the "rise" generally encompasses both the vertical component of the steps and the associated features that allow for safe navigation, including the handrails that provide support and safety for users.

While "landing" refers to the flat platform at the top or bottom of a series of stairs where people can stand, and a "stairwell" is the vertical shaft that houses a staircase, neither accurately describes the entire set of steps leading up from a threshold to the sidewalk. Similarly, "run" pertains to the horizontal distance covered by the steps, which does not encompass the entire assembly including rails.

Thus, when describing a complete set of steps that connects the threshold to the sidewalk, "rise" is the most appropriate term as it captures both the elevation and the associated safety elements required for effective stair design.
