The maximum height of normal stair risers is how many inches?

• A. 9
• B. 8
• C. 7
• D. 6

Answer: (C)

The maximum height of normal stair risers is specified by the building code to typically be 7 inches. This limit is established to ensure safety and accessibility in stair design. A riser height of 7 inches is considered manageable for most people, reducing the risk of missteps and promoting ease of use.

In the context of stair safety, lower risers help accommodate a wider range of users, including children, the elderly, and individuals with mobility issues. Maintaining a consistent riser height throughout a flight of stairs is crucial as well, as variations in height can lead to accidents.

The other options present higher riser heights, which do not align with established safety guidelines specified in various building codes. A riser height of 9 inches could increase the likelihood of stumbling or falling compared to the recommended height, while heights of 8 inches and 6 inches also fall outside the typical maximum. Hence, 7 inches stands as the standard for maximizing both comfort and safety on stairs.
