### How do you calculate stairs for carpet?

How much does it cost to cover 13 stairs? – (Image credit: Carpetright) To work out how much it costs to cover 13 stairs, you’ll need to work out how much carpet you will need. Follow these steps: Step 1. Measure the height and depth of each step and add these numbers together to get the length.

Step 2. Measure the width of the stairs and multiply the two figures to get the area of each individual step. Step 3. Multiply this figure by the number of steps in your staircase, in this case it would be 13. The average cost of carpet is between £15/$20 and £20/$27 per square metre, but what you pay will largely depend on what material you use.

When it comes to covering a straight set of stairs, you’re looking at spending between £80 and £100 on average. However, the price will vary depending on what materials you use, the type of staircase you have and if you need an underlay.

### How much carpet do I need for 13 stairs?

How much carpet is needed for both stairs and landing? – When it comes to volume, it’s all going to come down to how much carpet you need to cover your stairs and landing, and which carpet you go for! For example, if you have a staircase with 13 steps and 1.2 metres by 1.2 metres landing, you will need to calculate the total square metre coverage of the stairs and add this to the total square metre coverage of the landing to get your total – you would be looking at 10 square metres of carpet.

#### How much carpet do I need for 16 stairs?

Direction of the Pile – The carpet must run in the same direction on every stair, and the direction of the pile must go with the flow of traffic (from top to bottom, not from side to side). Example For a typical set of 16 box stairs measuring 3′ wide, using a carpet that is 12′ wide, you would require 12′ x 7′ (in a 12′ width of carpet, you get 4 widths of box stairs, (12′ divided by 3′) so every 12′ x 21″ gives you 4 stairs side by side on the roll).

#### How many meters is a staircase?

3. DESIGN CONSIDERATIONS –

- 3.1 General
- Differences in level should be illuminated or minimized as much as possible for the comfort of disabled people.
- A complementary ramped route, elevator or lift should be provided where there are steps in an otherwise accessible path.
- All steps should be uniform.

Circular stairs and stepped landings should be avoided (fig.1). Open risers are not recommended.3.2 Width The minimum width of a stairway should be 0.90 m for one-way traffic and 1.50 m for two-way traffic. For indoor stairs, the riser should be between 0.12 m and 0.18 m, and the tread between 0.28 m and 0.35 m.

- Sharp edges and overhanging nosing should not be used for treads.
- Nosing should be flush or rounded and should not project more than 40 mm.
- 3.5 Handrails

Handrails must be installed on both sides of the stairs and around the landing for gripping (fig.3). For stairs more than 3.00 m wide, one or more intermediate handrails could be provided (fig.5). The distance between the handrails when both sides are used for gripping should be between 0.90 m and 1.40 m (fig.5).

Handrails must extend a distance between 0.30 m and 0.45 m at the top and bottom of the stairs (see ) (fig.3).3.6 Tactile marking (fig.2) (fig.3) A textural marking strip should be placed at the top and bottom of the stairs and at intermediate landings to alert sightless people as to the location of the stairs.

The tactile marking strip should be at least 0.60 m wide and should extend over the full width of the stairs. To guide users with poor vision, the colour of the strip should contrast with the surrounding surface.3.7 Surface

- Landings, treads and nosing should be slip-resistant and free of projections.
- Exterior stairs should be pitched forward at 10 mm per metre to drain surface water.
- Slip-resistant stair nosing should be used to fix carpets on stairs.
- 3.8 Emergency stairs
- Emergency stairs should be identified by tactile markings.
- 3.9 Mechanical stairs (escalators)

Mechanical stairs can be provided with an adaptable tread at least 1.20 m long, if they are to be used by persons confined to wheelchairs (fig.6). The edges of escalators should be painted in a contrasting colour for the benefit of poor- sighted users.

## How do I calculate how many steps I need for stairs?

This guide reviews how to measure stair stringers, as well as how to cut stair stringers and the relevant building requirements. Measure the stairway’s total rise and divide by the estimated riser height (around 7 inches) for the number of steps.

### What is the standard size of stairs?

International Residential Code (IRC) – The International Residential Code dictates stair code requirements specific to residential buildings. The IRC stairs code states that, to comply with stairway requirements, the minimum width for residential stairs be no less than 36 inches.

### What is the ideal stair formula?

Figuring the rise and run of stairs can be as complicated as 1, 2, 3 Remember back in grade school when you were first learning to multiply and divide? Even though the problems all dealt with colliding trains and people who seemed to have a lot of fruit on their hands, the teacher promised this was real practical stuff that you’d need later on.

- Well, the teacher was right – at least, if there’s a stair-building project in your future.
- Building stairs is an art form perfected by carpenters over the centuries.
- There is a lot of conventional wisdom about what makes stairs comfortable and practical.
- There is also a fair amount of math involved in figuring out how to build them.

Most of the math is used to fix the rise and run – that is, the height of each stair plus the width of each tread. The rise and run distances determine how comfortable the stairs will be to use. If the rise and run are too great, the stairs will strain your legs and be hard to climb.

shorten your stride to match the stairs will wear you out.Over the years, carpenters have determined that tread width times riser height should equal somewhere between 72 to 75 inches.On a main stair, the maximum rise should be no more than 8 1/4 inches and the minimum run should be no less than 9 inches.

To determine how many steps, or treads, you need, measure from the top of the finished floor on the lower level to the top of the finished floor on the upper level. Don’t forget to include the finish – the flooring, the carpet, the tile, or whatever surface treatment the floor will get.

- Even if it adds up to just an inch or so, it will affect your calculations.
- A miscalculated stair with one step out of sync with the others will forever be a death trap for unwary feet.
- For a multi-floor house, each flight of stairs should be figured separately – but the rise and run have to be the same, even if the number of treads is different.

To figure the rise and run in a house with 8-foot ceilings, for instance, start by figuring the total vertical rise. By the time you add floor joists, subfloor and finish floor, the total is usually about 105 inches. A standard number of treads in a stair between first and second floors is 14.

- One hundred-five divided by 14 equals 7 1/2,
- That means the distance from the top of each step to the top of the next step will be 7 1/2 inches.
- With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches.
- Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 – within the conventional ratio of 72 to 75 inches.

With 14 10-inch treads, the total run of the stair will be 140 inches. In other words, the entire stair will be 105 inches tall and 140 inches deep. You can alter the rise and run to some extent. If you used 15 risers instead of 14, for instance, the rise would be 7 inches, and the tread width would be 10 1/2 inches (7 times 10 1/2 equals 73.5, within the rise and run guidelines).

- The goal is to create comfortable stairs in the space allotted, ones that are not too steep or too shallow.
- While you can make small adjustments in the rise and run, you have to stay within the guidelines of 72 to 75 inches riser times run.
- Another factor to consider is the head room available.
- On main stairs you need a minimum of 6 feet 8 inches between the top of each tread and the bottom of any obstruction above it.

In older houses, you have to be especially careful about altering the rise and run. If you increase the tread width, you may decrease the head room. Yes, it is pretty complicated. If trying to figure out how many apples Jane gave Sally if Sally gave Tom half of them makes your head ache, you probably wouldn’t enjoy building stairs.
