How Much Floor Space for Stairs in India?

A staircase is the connectivity between two floors of a house. It can be straight, L-shaped, U-shaped, curved, spiral, etc. We find some of them easier to ascend and in some others, we get tired while ascending, 

There are regulations in place regarding design and minimum width of the staircase, but usually wider staircases are recommended than the minimum width. I can help you know about the standard

size of stairs for residential in India.

According to the Indian National Building Code, the

minimum space for staircase

in terms of width in a normal residential building should be 3 feet and 6 inches, minimum width of tread without nosing should be 10 inches and if nosing is required, it should be 10 ¼ inches. Standard height of the riser should be 7 inches.

For commercial, industrial, assembly buildings like auditoriums, cinema halls, residential hotels, educational institutions, etc. minimum width of staircase should be between 5 to 7 feet and tread width should be 1 foot. Riser height should be 6 inches for the commercial buildings. This clears up

how much floor space for stairs in India for non residential properties.

The height of the rise of the staircase depends on the height of the ceiling of the floor. Higher the ceiling more the treads and risers will be required.

The staircase area, height, width, etc. should be in compliance with the local laws. So, you are advised to go through the local laws and regulations.

I hope standard size of stairs for residential in India along with non residential is clear now.

My staircase has become very old and the concrete below the stairs has been spalling after rainfall and water was leaking through them. So, I decided to reconstruct them recently and when I was working on staircase design, I learned quite a bit about how much floor space stairs can take up. It took quite a long time for me to design using normal staircase dimensions.

What is the Standard Staircase Area Size?

• First, you have to figure out the height of the staircase, which in my case was about 10 feet. This meant I needed around 17 steps, with each step having a rise of about 7 inches. 

• So, for the run, which means the amount of space the steps project forward, I used 1 foot per step, which added up to 17 feet with width of 4 feet each.

• Now, it wasn’t just the steps I had to consider. I needed a landing, too, because I didn’t want the stairs to go straight down and block the doors or windows on the lower floor. 

So, I opted for a 4x4 foot landing to turn the stairs around. This allowed me to change direction and make better use of the space without creating an awkward layout. It’s important to think about local building codes too, especially when it comes to the width of the staircase and the need for handrails. 

I stuck to the standard 4-foot width to make sure it was both functional and comfortable. In total, the stairs needed around 80 square feet of floor space approximately (4*4+4*16). So, if you’re planning something similar, I’d say budget at least 80 to 100 square feet, depending on your layout and height, length and width of stairs.

To ensure safety, accessibility, and adherence to building requirements, standard size for staircases are essential while constructing. These measurements determine the height, width, and depth of stairs, ensuring their users' comfort and security. For the construction of safe and reliable staircases in both residential and commercial structures, adherence to these standards is crucial.

What are the average staircase dimensions?

A staircase size in residential building must be at least 3 feet, 6 inches, and its treads must be at least 10 inches wide without nosing and 10 ¼  inches wide if nosing is required, under the Indian National Building Code.

To get to a ceiling or floor that is 12 feet high, there must be 21 stairs, 20 treads, and about 14 feet of stringer to climb.

How much space required for stairs?

A typical staircase takes up 30 square feet of area both above and below it. 

You can also use several online stair calculators. A digital tool called a "stair calculator" is used to compute the unit rise and run of stairs, the stair elevation angle, the length of the stringers, the step height, the tread depth, and the number of steps necessary for a specific run of stairs.

I have a friend who is an architect and he loves to talk about his work and share his insights on the same. One day he told us about the standard staircase size. So, I guess I can help you understand whatever my architect friend told me about the stairs standard size.

In India, the standard floor space for stairs is determined by building regulations and safety codes. The National Building Code of India provides guidelines for the design and construction of staircases in different types of buildings.

Staircase size in feet

According to the code, the minimum width of a staircase for residential buildings is generally 900 millimeters (approximately 35 inches). However, in public buildings and high-rise structures, the width may need to be larger to accommodate a larger number of occupants.

The code also specifies the standard staircase dimensions for the individual steps or treads and the risers. The tread depth is typically between 250-300 millimeters (10-12 inches), and the riser height is generally kept between 150-200 millimeters (6-8 inches). These dimensions ensure comfortable and safe climbing of stairs.

In addition to the dimensions, the code also includes requirements for handrails, lighting, and non-slip surfaces to enhance safety. The handrails should be provided on both sides of the staircase, and the lighting should be adequate to ensure visibility.

Now you know the standard staircase size.

When I was constructing my home, just like the other parts of the house, I gave special attention to the construction of the staircase. I am aware of the staircase dimensions in feet, that I followed while constructing a staircase in my house. 

What is the staircase standard size?

According to the Indian National Building Code, the standard size of staircase in feet in a residential building must have a minimum width of 3 feet, 6 inches, and its treads must be at least 10 inches wide without nosing and 10 inches and 10 ¼ inches wide if nosing is needed.

There must be 21 stairs, 20 treads, and roughly 14 feet of stringer to climb in order to reach a ceiling or floor that is 12 feet high.

I hope this suffices your understanding about the minimum space required for staircase.

A house or any other construction would not be complete without stairs. Building codes, aside from characteristics and calculations relating to staircase length, width, and height, as well as door location, must be taken into account when constructing a staircase. There are several stairs calculators available online. You can use the online staircase calculator to get precise staircase dimensions in feet.

The most essential part of your property that provides access from one floor to another is the design of your staircase. It may be linear, L-shaped, U-shaped, circular, twisted, or overhanging. And I prefer to go with a linear one for a better movement. This guide is about the standard size of staircase.

What is the staircase dimensions in feet?

The size of the steps in feet generally to be 3 to 3.5 feet wide for a typical household. Aakarshit also explained this in the previous answer. Based on the type of architecture and how they are measured from edge to edge. In most instances, the minimum is 2 feet 9 inches. For residential buildings, the minimum foot width without nosing is required to be 0.9 feet. For other buildings, it can be up to 1 feet. The riser's height must fall between 0.6 and 0.7 feet.

What is the minimum width of stairs residential?

The minimum width of a stair or staircase is 1 metre (1000 mm, 3 feet 3 inches), 1.5 metres for hotels and 2 metres for assembly structures like auditoriums, theatres, and theatres. It can be 1.5 metres for office buildings, 2 metres for educational structures and 2 metres for industrial and commercial structures. But a typical one for a typical residential dwelling is 3 feet 5 inches.

I hope you understood about the standard size of staircase.
