What is one disadvantage of improper stair riser height?

Improper stair riser height poses a significant safety risk, which is why the increased risk of accidents is the most relevant disadvantage. When stair risers are not consistent in height, it can lead to confusion for users, making trips and falls more likely. This inconsistency can disrupt a person's rhythm while ascending or descending, increasing the likelihood of misstep and resulting injuries. Maintaining uniform riser heights is crucial in providing a safe environment, especially in public spaces where foot traffic is high.

While factors like maintenance costs, material wastage, and aesthetic considerations may come into play in the broader context of building design and construction, the immediate concern with improper riser heights is fundamentally about safety and the potential for accidents. Thus, ensuring that stair risers meet the recommended height is essential for minimizing hazards and promoting safe usage.
