- Multiply the two numbers to get the total number of square inches of the step.
- Count the number of steps and multiply that number times the average square inches of each step.
How do you count steps on a staircase?
The easiest way to count the steps is to count the 'nosings' - the edge or arris of each step. That number will be the same as the number of risers, and will include the final nosing at the start of the landing at the top.
How do you calculate the height of stairs?
1 Measure the height, or "rise," of the space you want to make stairs. ... 2 Subtract 6–7 feet (1.8–2.1 m) from the total rise to account for headroom.

How do you find the total run of a staircase?
Find the total run by multiplying the individual run by the number of steps. The total run refers to how long your overall staircase will be. To determine the overall run, multiply the step run by the planned number of steps in your staircase.
When does a staircase count as a staircase when moving house?
As soon as you have two or more steps together in a group, you technically have a staircase. Most moving companies will charge a flat rate for each staircase and only charge for staircases with a certain number of stairs or more in them. For most companies this magic point is 5 steps.
How do you calculate stairs?

How to figure out how many stairs are there?
Divide the rise by 6 or 7 inches (15 or 18 cm) to find the total number of stairs. For larger stairs, divide by 6 and for smaller stairs, divide by 7. The total you get is how many stairs your future staircase will have so you can plan accordingly.
How to find the individual stair rise?
The stair rise refers to how high each individual step is. To determine the individual stair rise, divide the overall rise by the planned number of stairs.
How wide should a stair be?
Plan for the width of each stair to be 36 inches (91 cm). The stair width refers to how wide the top of each stair is, and it is perpendicular to the rise of each step. The average minimum width for each stair is 36 inches (91 cm), but you can make the stairs wider if desired.

If the rise is 42 inches (110 cm) and the number of stairs is 6, for example, each individual stair will have a rise of 7 inches (18 cm).
How to calculate stringer length?
Calculate your staircase's stringer length. Stringers run diagonally along the length of each stair to prevent them from collapsing. To determine their length, square the run, square the individual stair rise, and then add the 2 numbers together.
How to measure the height of a staircase?
Measure the height, or "rise," of the space you want to make stairs. Using a tape measure, make measurements of the total height of the space you want to make stairs from the bottom to the top. This is called the "rise" of your measurements and will determine how high your stairs will go.
How to draw a staircase?
Using graphing paper, draw a sketch of the staircase while marking the rise, run, number of steps, width, and length.

To the mover: NO! Every time the mover has to lift his foot to go up or down in a staircase, he/she considers that a step or stair. You will hear some people argue that steps are outside and stairs are inside and since you are quoting on the amount of stairs being moved over, that the steps are free. This is a myth. 3.
Does counting stairs count as a step?
Yes it does. It amazes me how many people like to argue this one. Remember that when counting stairs, you are counting how many times you have to lift your foot. If you have to lift your foot to get onto the landing, then it counts as a step. 5.
How to calculate stairs?
Stairs are counted from the first tread off the floor to the last one before the landing and there is always one more riser than treads . When calculating that needs to be remembered . So the going is divided by the number of treads but the rise is divided by the number of risers . The rise is the total distance from floor to floor , the going may or may not be restricted depending on the stairs final position . Various configurations, such as spiral , dogleg , winder etc can allow stairs to fit with a confined area , but all will be calculated on the total rise .
How are stairs determined?
That is determined in minimum number by the floor to floor height and maximum regulation riser height . Outside of that by reducing the rise and increasing the going there could be about twice as many depending on space available . Beyond that amount rises usually get too low to be practical and often a danger to climbing them and the likellyhood of tripping increased . So there is no fixed amount of steps and can range between the maximum amount to the minimum amount of treads needed and safe to use . Pre made stairs are usually made to fit a standard floor to floor height and will be close to the maximum rise that is permitted, this allows them to be fitted into the minimum space required . Non standard height ceilings will need custom made stairs but still follow the above rules .
How high should a step be?
an old ‘rule of thumb used to be double the rise (height of step) plus the go (length of step) equals 23 , therefore a 7″ rise and a 9″ go would be a comfortable step. If you needed to increase or decrease the height (to evenly space your steps to meet floor levels) the length of step should shorten or lengthen so as to remain comfortable.
How many landings are required for stairs?
depends on the height of your risers to each tread which in turn will be affected by the pitch of the stairs and at 12 feet you are going to be require it have at least one landing in most jurisdictions ( so you are going to need to check your local code)

Why do people step on the right foot first?
Most staircases are and odd number of steps to help keep people from stumbling. Most people are right handed, so they naturally step with the right foot first. So if the top of the stair was an even number they would be on their left foot. But their brain is used to telling the right foot to go first. So an odd staircase puts them back on the right foot....

How to count stairs with different risers?
You can easily count upstairs with different sized risers by using a few simple tools. You will need a measuring tape, stair riser angle finder, and a pencil that is long enough to reach across the stringer from tread edge to tread edge. Measure the height of every stair step on one side of the stringer at the middle point between the two ends. Write down each of these heights to the side of your drawing paper. Measure the distance of every step on one side of the stringer at the middle point between the two ends. Write down each of these horizontal lengths to the side of your paper as well.
How to find the total number of treads on a flight of stairs?
The total number of treads on any given flight of stairs equals the rise divided by 12, plus 1. The risers are counted by multiplying the rise by 4, then dividing that number by twelve. That number will be equal to the number of risers per flight.
Why is it important to measure up all of your stairs?
It’s extremely important to measure up all of your stairs in order to get an accurate reading on the stringer. Also, some larger homes in Houston have a center hall with several staircases that are connected to the entrance of the home.

What is a nosing on a tread?
Nosing: The nosing is the protrusion at the edge of a tread that hangs over the riser below. Not all steps have a nosing, but when present, the nosing is included in the length of the tread. The main purpose of nosing is to improve safety by providing extra space on which a person can place their feet.

What is headroom in stairs?
Headroom: Headroom is the height measured from the top of a tread to the ceiling above it. While building codes for headroom are primarily intended to ensure enough room for people to comfortably use the stairs, the codes typically require far more room than the average height of a person to allow for moving larger objects such as furniture.
How long should a tread be?
Building codes generally suggest that the minimum length of a tread be 10 inches (25.4 cm). Rise/Riser: The rise, or height of a step is measured from the top of one tread to the top of the next tread.
Where is the nosing measured?
Its length is measured from the outer edge of the step, which includes the nosing if it is present, to the vertical portion of the stair called the riser. Both nosing and riser are discussed below. When measuring total run of a staircase, the length of the tread above the last riser is not included in the measurement.
