Question: 1 / 400

What is the maximum height for stair risers as per construction regulations?

6 inches

7 inches

The maximum height for stair risers is commonly established at 7 inches according to various building codes and safety regulations. This standard is in place to ensure safety and accessibility in design. A height of 7 inches strikes a balance between creating a comfortable step for users and minimizing the risk of accidents, as taller risers can increase the risk of misstepping.

This regulation also facilitates easier navigation for all individuals, including those with mobility challenges. By maintaining this maximum height, builders help ensure compliance with accessibility standards and promote safer building practices.

The other options exceed the generally accepted maximum height for risers found in most building codes, leading to potential safety concerns and making compliance more challenging in terms of building design and usage by the general public.
