Staircase design depending on local Building Code guideline in your location. To complete the comfort zone, carpenter and the architect design the staircase or stairs according to code. There is a lot of factors is kept in consideration while designing the staircase such as what will be the the relationship between rise and run ratio, what will be stringer length and what will be landing and ceiling height and how many stairs do you need to go up 10 feet.

Number of stairs depending on the height of a riser to each tread and it will be also affected by pitch of the stair or staircase. Number of stairs or number of riser (step) is same things. Basically all are depending on height of stairs which you will need to go up which all are based on local building Code that says that you need to achieve comfort zone and a relationship between rise and run.

There is a various component of stair or staircase such as step, riser, tread or going, stringer length, waist slab, landing and flight.

Tread is the horizontal top portion of a step where foot rests is known as tread. The size of tread or going or run ranges from 10″ to 11″ for residential buildings. Factories, hospitals and public buildings to 300mm or 12″ where large number of persons use the staircase. In some cases nosing is provided the tread is projected outward to increase the space. Maximum nosing will be in 1 inch.

Riser is the vertical distance between two successive steps is termed as riser. The size of the riser ranges from 150 mm or 6″ for public buildings to 190 mm (7- 1/4″) for residential buildings and factories and maximum about 7-3/4″.

Waist is the thickness of the waist-slab on which steps are made is known as waist. The steps of the staircase resting on waist-slab can be made of bricks or concrete or wood. Going is the horizontal projection between the first and the last riser of an inclined flight. The going should not be less than 250mm or 10″.

Number of stairs steps depending on the height of a riser to each tread and it will be also affected by pitch of the stair or staircase. In this artical you know about how many stairs do you need to go up 10 feet and how do you calculate the number of stairs required for any given height such as 10 feet, 11 feet, 9 feet, 8 feet and 12 feet.

**How many stairs do you need to go up 10′, 12′, 8′, 9′, 6′ & 7 feet**

Usually the Riser (height of step) will be between 7′-1/4″ to 7′-3/4″ and minimum run at least 10″ and maximum to 11″ to 12″. Many carpenter and architect follow the rules to determine comfort rule as rise plus run is equal to 18″ or 2 times rise + run is equal to 25″. To figure the number of stairs you would need to go up 10 feet take the height of one riser 7 inches on average.

Total height from top of 1st floor to top of 2nd floor which is divide by 7 inch to give number of stairs or steps or riser in any particular height of ceiling which you will need to go up.

To figure the number of stairs you would need to go up 10 feet, multiply the height of floor by 12 to convert feet in inches, and then divide the floor height in inches by 7. The result will be your number of stairs you need to go up 10 feet. Number of stairs = (10×12)÷7 = 17.24, round it 18. So, you would need approximately 17 to 18 stairs (steps) to go up 10 feet.
