Every landing should be at least how many inches measured in the direction of travel?

The correct answer is that every landing should be at least 36 inches measured in the direction of travel. This requirement is established to ensure safety and functionality in stair construction, particularly regarding the ease of movement and the ability for individuals to navigate landings without obstruction. A landing that is at least 36 inches wide provides sufficient space for someone to rest, adjust their balance, or turn around if necessary, enhancing safety and accessibility.

In residential and commercial buildings, adhering to this minimum width can prevent accidents and ensure compliance with building codes, which often stipulate dimensions to accommodate various needs, including those of individuals with disabilities. This consideration for safety reflects a commitment to creating environments that support all users effectively.
