You can learn more about the complete construction stages in our guide on Building Construction Process Step by Step – Complete Guide for Beginners.
Parts of a Staircase in House Construction
Before performing staircase calculation for house construction, it is important to understand the basic parts of a staircase.
Staircase Components
Riser
The vertical portion between two steps is called the riser. It determines the height of each step in staircase calculation for house construction.
Tread
The horizontal portion where a person places their foot is known as the tread.
Flight
A continuous series of steps without interruption is called a flight of stairs.
Landing
A landing is a flat platform provided between 2 flights of stairs.
Waist Slab
The inclined slab supporting the staircase is called the waist slab.
Understanding these parts helps in accurate staircase calculation for house construction.
Standard Staircase Dimensions for Residential Houses
During staircase calculation for house construction, standard dimensions should be followed.
The following table shows the standard staircase dimensions commonly used in residential house construction.
Staircase ComponentStandard SizeRiser Height150 mm – 175 mmTread Width250 mm – 300 mmStaircase Width900 mm – 1200 mmLanding WidthEqual to staircase width
These dimensions are commonly used in residential house construction.
The standard staircase dimensions used in residential buildings are generally based on recommended construction practices and building standards. According to the National Building Code of India (NBC), proper staircase design is important for safety, accessibility, and comfortable movement between floors.
Staircase Calculation for House Construction (Step by Step)
Let us perform staircase calculation for house construction using a practical example.
Given Data
Floor to floor height = 3 meters
Riser height = 150 mm
Convert the height into millimeters.
3 meters = 3000 mm
Step 1: Calculate Number of Risers
Formula:
Number of Risers = Total Height / Riser Height
Number of Risers = 3000 / 150
Number of Risers = 20
Therefore, the staircase will have 20 risers.
Step 2: Calculate Number of Steps
The number of steps is always one less than the number of risers.
Steps = Risers – 1
Steps = 20 – 1
Steps = 19 steps
Step 3: Calculate Staircase Length
Assume tread width = 250 mm
Formula:
Total Stair Length = Number of Steps × Tread Width
Total Stair Length = 19 × 250
Total Stair Length = 4750 mm
Convert into meters.
4750 mm = 4.75 meters
Therefore, the staircase length for house construction is 4.75 m.
Step 4: Staircase Width for House Construction
While performing staircase calculation for house construction, staircase width should be selected carefully.
Typical staircase width for residential buildings:
900 mm – 1200 mm
Most houses use 1000 mm staircase width.
Step 5: Concrete Quantity for Staircase
Staircase calculation for house construction also includes estimating concrete quantity.
Assume:
Staircase length = 4.75 m
Staircase width = 1 m
Waist slab thickness = 0.15 m
Formula:
Concrete Volume = Length × Width × Thickness
Concrete Volume = 4.75 × 1 × 0.15
Concrete Volume = 0.7125 m³
Therefore, approximately 0.71 cubic meters of concrete is required for the staircase.
Concrete quantity calculation is an important step in staircase construction. Civil engineers often estimate concrete using standard formulas. If you want to learn detailed concrete calculation methods, you can read our guide on Concrete Calculator Formula – How to Calculate Concrete for Slab, Beam and Footing.
