What is the typical height for stair risers?

  1. 5 to 6 inches

  2. 6 to 7 inches

  3. 7 to 8 inches

  4. 8 to 9 inches

The correct answer is: 7 to 8 inches

The typical height for stair risers is generally considered to be between 7 to 8 inches. This height range is widely accepted in building codes and safety guidelines due to its balance between comfort and functionality when ascending or descending stairs. If risers are too low, they may require more steps to reach a certain height, which can be tiring. Conversely, if they are too high, it can increase the risk of accidents, as the step-up might be difficult for some individuals, particularly the elderly or those with mobility issues. This height of 7 to 8 inches also complies with most local and national building codes, which often specify a maximum riser height to ensure safety and ease of use. Understanding this standard is essential for home inspectors, as they assess whether stairs meet safety requirements and provide appropriate guidance to homeowners or potential buyers regarding compliance with these regulations.
