Stairs with landings are very common in stair building design. There are several reasons why you would consider adding a landing, or series of landings, to your stair design. Two of the many reasons are covered on this page.
Sometimes you don't have the room for a long straight run of stairs. Or you may want to break up a long run of stairs with a landing as a place to rest or take in a particular view of a room or outdoor scene before continuing on.
There are also situations where the slope of the terrain changes from point to point and a series of level walkways will be required between runs of stairs.
In the following sections, I will explain both scenarios in more detail. Please note that this page assumes you already know how to layout and cut stair stringers. If you need a refresher, read the building stairs tutorial.
In this scenario, our design requires access to be built from a first floor landing to a second floor landing. A mid level landing is required as per design specifications. The height of the second floor is 110 inches above the first floor. Enter this number into the stair calculator in the Total Rise field. Since the default values in the remaining input fields are ideal, we will leave them alone. Click Calculate Stairs.
Note that since there is a mid-level landing in this design, the Total Run results do not apply. The Total Run only applies to a single straight run of stairs.
The height of each step is 6 7/8 inches. The mid-level landing counts as a step in this design. Both upper stair stringers and lower stair stringers have the same number of treads.
It doesn't have to be this way, you can place a landing anywhere along the stair run that serves your needs. You can move it to where you have one more step at the top and one less step at the bottom.
The height of the landing is determined by where it is located along the stair run. In this design, since it is half way from the top level, it is 8 steps high (8 x height of each step (6 7/8) equals 55 inches).
The horizontal positioning of the mid-level landing is determined by the number of treads on the stair run. In this case, it is 7 (7 x tread depth (10.5) equals 73.5 inches).
Build the landing at the specified height and distance and add the stringers as shown in the above drawing. For more information about building stairs with landings, visit building stairs and stair calculator.
In this scenario, the horizontal distance between the lower level (A) and the upper level (D) is far apart, making the tread depth in a typical stringer design, uncomfortable for walking and impractical to build.
The height between the lower slab/landing (A) and the upper deck/landing (D) is 58 inches. Enter this number in the Total Rise field. Accept the other default input values and press Calculate Stairs.
The results from the stair calculator indicates that the typical step height is 7 1/4 inches, and a total number of 8 steps (risers). In the diagram shown above, you may have noticed that the landing is in the middle, and that the height between the lower level (A) and (C) is the same between (C) and (D).
You could have placed the mid-level landing (C) at the same level as the third step, leaving 5 steps between (C) and (D). It all depends on your terrain and design requirements.
