However, if the steps don’t have nosings but have solid risers, the tread depth should at least be 11 inches. The distance between these two steps should not be less than 10 inches.
Its depth is measured from the front edge of a step to the front edge of the next step. The stair tread is the top surface of a step. For this reason, it is imperative that the maximum height of the riser and minimum width of tread must be followed. When the risers or treads have inconsistent measurements, it can interfere with a person’s rhythm when he goes up and down the stairs. Your stairs should be uniform to ensure safety. The headroom is measured starting from the stair tread to the ceiling, and it should be at least six feet and eight inches. Plus, having proper headroom will prevent users from hitting their heads when going down the staircase. HeadroomĪlways remember that your staircase should have plenty of headroom so that a person won’t duck down when going up or down the stairs. Other than that, there is no requirement for the rise length because staircases can vary. As such, if the staircase exceeds 12 feet, a landing must be placed in-between to break up the stairs. Ideally, a landing must be placed every 12 feet of rise. The reason is that it allows you to determine where you should place the landing or floor level. Even if stairs come in various shapes, their rise is a vital measurement. The rise refers to the overall height of the staircases. Vertical Rise and Headroom Vertical RiseĪ staircase should be broken up into reasonable intervals to ensure safety thus, the height limit based on the building code should be followed to ensure that the user will be able to take some rest and prevent the negative effects of a continuous staircase. If there are two handrails, the clear width should at least be 27 inches. As such, when a handrail is installed on one side, the clear width of the stair should not be less than 31 1/2 inches. When the handrails are included, they should not take more than 4 1/2 inches of space. The stair width is the distance from one side of the stair to another, and its standard measurement is at least 36 inches, excluding the handrails. To avoid these types of accidents, it is recommended to follow the standard stair width. Having narrow stairs will hinder the people from escaping safely out of the building. Aside from that, narrow stairs can also be dangerous, especially in emergencies.
For one, carrying objects up and down the stairs can be difficult, and it may even lead to falls. Keep in mind that a staircase that is too narrow is a hazard in various ways. Code Requirements for Residential Handrails.Stair Tread Depth and Stair Riser Height.
