What does riser height refer to?

Riser height refers to the vertical distance between treads or platforms in a staircase, increasing from one tread to the next. It is a critical measurement in construction and safety as it ensures uniformity and ease of use for stairs, which directly impacts the safety of individuals using them. If riser heights are inconsistent, they can lead to trips and falls, which is why regulations specify maximum and minimum height dimensions. Understanding the correct riser height is essential for maintaining compliance with building codes and ensuring safe access between different levels of a structure.

The other options, while related to heights in various contexts, do not specifically define riser height associated with stairs or platforms.
