The average stair width in america is about 36″ wide which is actually the minimum according to most building codes. Though the entire 36″ isn’t used, it is enough to account for handrails which can take up a few inches. A railing can take up anywhere from 2-5inches each.
How Wide Are Stairs?
Stairs are an essential part of everyday life, from accessing the second floor of a building to getting to the top of a mountain. But just how wide should stairs be? The answer depends on a variety of factors, including type of stairs, purpose, and the type of people who will be using them.
When it comes to residential homes, the width of stairs depends on the type of staircase. Straight staircases, which are the most common type of staircase, should be at least three feet wide. Curved staircases should be at least four feet wide. For extra safety, stairs should be at least five feet wide.
In commercial spaces, stairs must be designed to meet building codes and standards. Stairways in commercial buildings should be at least four feet wide to accommodate two people walking side by side. They should also have a landing at least every twelve steps to provide a safe resting spot. For safety, they should also have handrails on both sides of the stairs.
The width of stairs also depends on the purpose of the stairs. Stairs that are used for storage or access to an attic should be wider than those used for everyday use. Stairs used for carrying large items up and down should also be wider than regular
