What is the maximum acceptable height difference between risers for ensuring stair safety?

1/4"
1/2"
3/8"
1/8"

The correct answer is: 1/4"

The maximum acceptable height difference between risers for ensuring stair safety is 1/4 inch. Maintaining consistent riser heights is crucial for preventing trips and falls, as even slight variations can lead to a loss of balance when navigating stairs. Stairs are designed for smooth transitions, and a variance greater than this limit can create an unsafe environment. In building codes, a maximum difference of 1/4 inch is often specified to provide a reasonable tolerance while ensuring safety standards are met. This standard is supported by safety organizations and building authorities, emphasizing the need for uniformity in stair construction and design. By adhering to this guideline, builders and inspectors can help ensure that stairways are safe for all users.
