Staircases are any space’s showstopping statement. Whether it be at the entrance, central, or end of space, staircases are a focal point of creativity and planned technicality. This personalized sculptural piece of art exhibits uniqueness to any interior design or outdoor setting. They may be straight, round, or consist of two or more straight pieces connected at angles. Natural stone stairs for interiors, landscaping or exteriors elevates and enhances this artistic piece in homes, commercial spaces, and patios. The beauty of natural stone and its versatility allows for it to be used in various styles for stairs, landscaping, pools, garden steps, and natural stone porch steps- from classic to modern and contemporary features.

Our interior design experts explain in detail the components of a staircase to help customers build the right staircase composition using the most suitable stone for stairs. 

Components of Staircases:

  • Tread: The section of the stairway that is stepped on is known as the tread. It’s calculated from the step’s outside border to the vertical “riser” between them.
  • Riser: The vertical section of the stair that runs between each tread. For an “open” stair effect, this may be absent.
  • Nosing: The edge of the tread that protrudes above the riser beneath is known as the nosing.
  • Starting step or Bull Nose: When stairs are open on one or both sides, the first step above the lower floor may be broader and rounder than the subsequent steps, with the balustrade or handrail forming a semi-circle around the diameter of the rounded area and the railing having a horizontal spiral. The balusters can form a larger, more stable basis for the handrail’s end thanks to the initial steps.
  • Trim: Trim is commonly used where walls and floors meet, as well as beneath treads to hide the exposed join between the tread and riser.
  • Stringer Board: The stringer board, which is a structural component, supports the treads and risers. The treads are typically supported by two stringers, one on each side of the stairs, but they can be supported in a variety of ways.
  • Balustrade/ Handrail: When stairs are open on one or both sides, the first step above the lower floor may be broader and rounder than the subsequent steps, with the balustrade or handrail forming a semi-circle around the diameter of the rounded area and the railing having a horizontal spiral. The balusters can form a larger, more stable basis for the handrail’s end thanks to the initial steps.
  • Winders: Winders are steps with one side narrower than the other.

Anti-Slip Stairs and Floors

Marble staircases are the most famous natural stone selected to create extravagant indoor staircases. They are naturally resilient and beautiful- boldly expressed through their veining and brilliant colours.

Marble steps are also used outdoors as they serve many purposes. Natural stone garden steps create a pathway from one flower bed to the other. Marble is also used as natural stone porch steps to connect outdoor areas and levels. And may also be used as natural stone steps for pools.

Stone for interiors must be carefully considered when applied especially when applying marble stair tread facings to make sure that treads are anti-slipper for the regular everyday multi flight of stairs use. It is best to consult with an expert to select the suitable natural stone for landscaping and stone patio steps that meet the function, purpose and style of any space.


EMG manufactures anti-slip stair treads and flooring. The finishing method, which grooves a pattern into the present surface, quickly improves traction on slick stairs and floors, is what counts most.

The shallow groove acts as a tread, eliminating water film from your shoe’s sole and preventing hydroplaning. Smooth surfaces underfoot may appear to be unsafe, but they can be particularly perilous when mixed with water.

Serious injuries can be averted by using slip-resistant stairwells and flooring. Indoor staircases, outdoor steps, landscaping, and swimming pool areas all benefit from anti-slip surfaces created with the right natural stone and appropriate finishes.

Each step’s rise height is calculated by comparing the top of one tread to the top of the next. It is not the riser’s physical height; the latter does not include the tread’s thickness.

From the border of the nosing to the vertical riser, the tread depth or length is measured. When it comes to stair treads and risers installation, risers should be installed first then treads, starting from the bottom up.

The horizontal distance between the first and last risers is the total run of the steps. Due to the nosing overlapping between treads, it is frequently not merely the total of the individual tread lengths.

The entire rise of the stairs refers to the distance between floors (or landings) that the stairwell spans.

The whole ascent divided by the total run is the stair’s slope (not the individual riser and treads due to the nosing). The rake or pitch of the steps is another name for it. The pitch line is an imaginary line that runs along the tip of the treads’ nosing.

The distance between the nosing of a tread and the ceiling above it is known as headroom.

The inner radius of the curve may result in unusually narrow treads for curved staircases. The “walk line” is an imaginary line that extends a short distance from the inner edge and along which people are expected to walk. The distance will be specified by the building code. The minimum tread size at the walk line will thereafter be specified by building codes.

To avoid any misunderstanding, the number of risers in a set of stairs is always the same as the number of treads.

Guide to Staircase Measurements


stair stringer calculator is the simplest way to figure out the rise and run. The following steps can be used to determine standard dimensions.

  • Riser height: 8.25 inches is the maximum riser height (210 mm). Typically, the minimum riser height is 5 inches (125 mm).

          For private residences, the minimum tread length is normally 9 inches (229 mm) including the nosing.

  • Nosing: maximum protrusion of the nosing, usually 1.25 inches (32 mm) to prevent people
  • Handrail: The height of the handrail is typically between 34 and 38 inches (864 and 965 mm) measured from the tread snout. On landings, the handrail’s minimum height varies, although it’s normally 36 inches (914 mm).
  • Handrail’s diameter should be between 1.25 and 2.675 inches in order to be comfortable to hold (37 and 68 mm).
  • Handrail balusters: maximum space between balusters is normally 4 inches (102 mm).
  • Openings: (if any) between the bottom rail and the treads are usually no more than 6 inches wide (152 mm).
  • Floor and landings in between the maximum vertical heights should provide places for people to relax while also limiting the height of a fall.


To build staircases, there are regulations for safety precautions you must be aware of and adhere to. Learn more about protection from falling, collision and impact from the Ministry of Housing, Communities and Local Government of England.
