What is the Space Between Steps on a Staircase Called?

The Riser: The Vertical Space that Defines Each Step

The space between two consecutive steps on a staircase is called the riser. It is the vertical component of the stair, creating the height difference between each tread. Risers are crucial in determining the overall rise or steepness of the staircase.

Riser Design and Functionality

Closed Risers: In a closed riser staircase, the space between treads is completely filled with a solid material, usually the same material as the treads themselves. This creates a visually enclosed and traditional look.
Open Risers: In contrast, open riser staircases have a gap between the treads, allowing light and air to flow through. These staircases create a more modern and airy feel, but require careful consideration for safety, especially in homes with children or pets.

Building Codes and Riser Height

In the United States, building codes specify guidelines for riser height to ensure safety and accessibility.

Maximum Riser Height: The International Residential Code (IRC) stipulates a maximum riser height of 7 ¾ inches (196 mm) for residential stairs. This limitation helps prevent overly steep staircases that could increase the risk of falls.
Uniformity: The code also requires that the variation in height between any two risers within a flight of stairs not exceed ⅜ inch (9.5 mm). This ensures a consistent and predictable stepping pattern, minimizing the likelihood of missteps.

Riser Design Trends

Contemporary Styles: Open riser staircases have gained popularity in recent years, especially in modern and contemporary homes. They contribute to a more spacious and visually open feel, enhancing the flow of light and air throughout the space.
Mixed Materials: Using contrasting materials for risers and treads is a popular design trend. This creates a visually interesting and dynamic staircase while also highlighting the distinction between the horizontal and vertical elements.
Lighting: Integrated lighting within or beneath the risers can enhance the visual appeal and safety of the staircase, especially in open riser designs where the space between treads is exposed.

Conclusion

The riser, though often overlooked, plays a vital role in the functionality and aesthetics of a staircase. Its height and design influence the overall safety, accessibility, and visual appeal of the stairs. Understanding building codes and incorporating current design trends can help you create a staircase that is not only functional but also a beautiful focal point in your home.
