What is the minimum riser height according to the course learned?

The minimum riser height for stairs is specified to ensure safety and accessibility. According to the guidelines studied in the course, the minimum riser height is 4 inches. This height ensures that stairs are comfortable to ascend and descend, reducing the risk of tripping while providing a sufficiently stable step for users.

Establishing a minimum height requirement helps maintain uniformity across staircases, as consistent riser heights contribute to efficient navigation and can be particularly important in public buildings or residential settings where varying heights may pose challenges for those with mobility issues. The requirement discourages excessively low steps that could create hurdles and serves to improve the overall safety and functionality of a staircase.
