What is the space between stairs called?

The space between two stair treads is referred to as a riser. This vertical component contributes to the overall rise of the staircase, determining the height you climb with each step. Risers can be either open or closed, depending on the design and style of the staircase.

• Open Risers: Open risers leave a gap between the treads, allowing light and air to flow through the staircase. They create a more open and airy feel but might not be suitable for all homes, especially those with young children or pets.
• Closed Risers: Closed risers have a solid panel or board that fills the space between the treads, providing a more traditional and enclosed look. They offer additional safety and can help reduce noise transmission between floors.

While the riser is the primary space associated with stairs, other important spaces exist in a staircase:

• Tread: The horizontal part of the stair you step on is called a tread. Its depth determines the comfort and safety of each step.
• Nosing: The nosing is the rounded or projecting edge of the tread that extends beyond the riser. It provides visual definition to each step and can help prevent slips and falls.
• Stringer: The stringer is the structural member that supports the treads and risers, running along the sides of the staircase. It can be open or closed, depending on the design.
• Handrail: The handrail provides support and stability while ascending or descending the stairs. It runs along the side of the staircase, attached to the newel posts and balusters.
• Landing: A landing is a platform between flights of stairs, providing a resting point and changing the direction of the staircase.

Together, these elements create a functional and aesthetically pleasing staircase that serves as a vital connection between different levels of your home. Understanding the terminology and function of each component can help you make informed decisions when designing, renovating, or simply maintaining your staircase.
