Main Parts Of A Staircase

Staircases are an unavoidable aspect of our daily lives. Not only do they enhance a home’s visual appeal, but they also serve as a functional means of moving from one floor to another. Staircases are the central axis of a home, requiring a delicate balance between welcoming aesthetics and practicality.

The Anatomy of Staircases: Form and Function

The Diversity of Staircases

Staircases come in a wide variety of shapes and patterns, with some installed within the house, while others grace the exterior. The style and design of these staircases can be influenced by numerous factors, including the homeowner’s preferences. When designing a staircase, several critical elements impact its safety and comfort.

The Key Components of a Staircase

Handrails, also known as bannisters, are protective bars that run alongside a stairwell, providing essential safety features. A stairwell may have handrails on one or both sides, offering support, especially for the children, during ascent and descent. Beyond their safety role, handrails also enhance the overall aesthetics of the staircase. Materials commonly used for handrails include cast iron, wood, copper, stainless steel, and aluminium.


Balusters, also known as guards or spindles, secure handrails in place. These vertical posts connect the handrail to the steps or treads, protecting the handrails from damage and bolstering their structural integrity. Balusters, when arranged uniformly, form an attractive balustrade. Materials like marble, glass, acrylic, wood, aluminium, cast iron, and stainless steel are frequently used in their construction.


Staircase landings are sections of the floor located at the top or bottom of a staircase, facilitating changes in direction. Two common types of landings are half-space and quarter-space landings, with the former extending across the entire staircase and the latter spanning half its width. Landings offer several benefits, including enhanced safety, improved slope, structural stability, and the ability to navigate corners.


The tread is the flat, horizontal surface upon which you place your feet when ascending or descending a staircase. It is arguably the most critical component of a staircase, as it defines its primary function. Treads can be crafted from a variety of materials, including acrylic, wood, steel, tile, granite, glass, and treated wood.


The riser is the vertical element that connects two treads, forming a step. Staircases with risers are known as closed-tread stairs, while those without are referred to as open-tread steps. The combination of treads and risers defines the structure of the step, serving both functional and aesthetic purposes.


Nosing is an overhang on the tread that extends beyond the riser, enhancing the staircase’s aesthetic appeal and providing a wider surface for use. It also contributes to the overall safety and usability of the steps.


The stringer, often made of materials like MS, wood, or steel, serves as the backbone of the staircase. It joins the treads and risers together and can be positioned at the steps’ centre, side, or both sides, providing crucial structural support.

Rise & Run

The overall ascent of the staircase is represented by the vertical distance between the first and last treads, known as the rise. We refer to the horizontal distance between the first and last risers as the run, also known as the going of a flight.
