Simply extend a measuring tape down through the stairway opening in the upper floor and measure the distance between the surface of the upper floor or level and the surface of the lower floor or level. That will be the total rise.

How do you calculate total rise of stairs?

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. 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 do you figure out how many steps are in a slope?





The formula for measuring how many steps you need is really simple. It’s the height of the hill from top to bottom in inches divided by anywhere between 6 and 8 for this type of stair. Because ours was 28 inches from the top of the slope to the bottom when you divide by 7, you get.. 4!

How do you build stairs on unlevel ground?

Quote from the video:
Quote from Youtube video: Process but to be honest my habit is to always get stuff level whenever i'm working on it whether i'm utilizing the level or. Not. I will be using two and a half square eleven gauge for my legs.

How do you calculate total increase?

Multiply your figure for unit rise by your figure for total run to get the total rise. Using the example, it would be six inches times 13 feet. The total roof rise in the example equals 78 inches.

How do you calculate rise over run?

Rise over run formula, calculating by hand



All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run).

How do you calculate riser height?





Take the total rise measurement (104 inches) and divide by the number of risers (13).

  1. 104 / 13 = 8. Stairs are cut to the nearest 1/16”. In this particular example the riser height is exact. If it. …
  2. 12 * 9 =108” You must now add 2.25” or 1.75” for nosing and riser thickness. Most stairs will be 2.25”.


What is the average slope of a staircase?

The typical stairs slope for steep stairs varies between 50 and 70 degrees. Steep stairs like ship stairs, spiral stairs, and alternating tread stairs have typical slope between 50 degrees and 70 degrees to save space.

How do you calculate stair riser and tread?

From the above Diagram,

  1. The staircase has divided into two flights providing a landing slab at mid of the staircase height.
  2. So Number of Riser = Height of Staircase / Height of one Rise.
  3. = 1500/150.
  4. = 10 Nos.
  5. So as per standard, we are providing 300 mm as tread length.
  6. Number of Tread = Length of Stair/One number of Tread.

What is RISE run and slope?



The slope of a line is expressed as a fraction that is commonly referred to as rise over run. The numerator (rise) refers to how many units up or down and the denominator (run) refers to how many units left or right. The direction will depend on whether or not the slope is positive or negative.

How do you calculate stairs for a landing?

Quote from the video:
Quote from Youtube video: And that will be to simply divide the overall height or the total rise of the stairway. Or the distance. Between the top of the lower level.

Does the landing count as a step?

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.

What is standard stair landing size?



36 inches

Stair Landing Length: Every landing shall have a minimum dimension of 36 inches (914 mm) measured in the direction of travel. Some codes such as Florida in the U.S. require that the landing length be at least 44 inches.
