What is the maximum height of stair risers allowed?

• A. 6 inches
• B. 7 inches
• C. 8 inches
• D. 9 inches

Answer: (B)

The maximum height of stair risers allowed is specified in building codes to ensure safety and accessibility. The correct answer reflects the standards set by organizations like the International Building Code (IBC) and Accessibility guidelines. A maximum riser height of 7 inches is considered optimal for creating a comfortable and safe staircase. Heights above this can lead to increased risk of tripping and difficulties for individuals with mobility issues. This height allows for smoother ascents and descents and helps ensure that staircases are usable for the general population, including children, elderly persons, and those with disabilities. Other options suggest heights that exceed what is generally permitted by these guidelines, which would not provide the same level of safety and ease of use. Therefore, adhering to the maximum of 7 inches helps to maintain consistent and safe construction practices in stair design.
