While long staircases may require landings due to space constraints, these are always just found in structures with more distance between floors.
While one straight run or flight of stairs might be suitable, it just might not be feasible in your home.
You may have to utilize a landing, and if so you would then have two separate “flights” of stairs instead of one.
A flight of stairs can be a showpiece in your household, especially if you choose floating stairs or satisfactorily finished hardwood treads.
The uniform aesthetic combined with extraordinary finish details can generate a flight of stairs as a showpiece.
Breaking up a satisfactorily finished flight of stairs with a landing does not have a different aesthetic.
One flight of stairs can save an area in a home and can similarly be visually appealing to the aesthetic of the house, as long, straight lines make for pleasing sightlines in a space.
It is standard for the houses to have either between 8 feet and 10 feet ceilings, with 8 feet being the extensively common.
Unless you have a split-level house, dwellings with ceilings of these heights will nearly always have at least one flight of stairs.
Flights of stairs are more popular clearly because there isn’t the space to have a landing in a conventional house, and there isn’t a requirement.
For example, your house has 8feet ceilings, with 10inches wide joists supporting the floor above. 10inches wide joists are 9¼inches wide. You similarly have a ¾inches subfloor on top of those joists.
Therefore, the total rise from the ground to the top floor of your flight of stairs is 8’10”. Transform that total into inches to get 106 inches.
We will utilize the maximum permitted stair rise per the IRC which is 7.75inches. Divide 106 inches by 7.75 inches and you get 13.7 inches. Therefore, you will need 14 steps. Divide 106 inches by 14 to discover the rise per step and you get 7.6 rises per step.
The length of stairs can differ widely since tread depths frequently observe a wider variance than riser height. Since vertical drop is more of a safety concern per step than tread depth, builders frequently manipulate tread depth to fit horizontal space.
The lowest tread depth of a residential step is 10 inches. Each tread must possess a nosing that is at least ¾ inches beyond the front perimeter of the step and no more than 1 ½ inches. There is no extreme tread length.
Computing the length of a flight of stairs involves recognizing the depth of your tread and the length of the stair tread nosing. The lowest tread nosing is ¾inches. Therefore, if you have 10 inches treads, subtract ¾inches for true horizontal span so, 9¼ inches.
A flight of stairs is generally the height of the ceiling plus the framing and subfloor of the floor above where the stairs end. In a space with 8 feet ceilings, a flight of stairs is anywhere from 8 feet 8 inches to just over 9inches high.
Houses with ceilings that are 9 feet or 10 feet will have stairs that are either 10 feet or 11 feet, respectively. Similarly, the real height depends on the floor framing and, to a lesser extent, the subfloor on the top floor.
To compute the stair height, take the ceiling height and add the width of the joists that frame the ground where the height of the stairs terminate. Generally, this is either 8inches, 10inches, or 12inches dimensional.
Then you have to add the thickness of the subfloor generally between ½inches and ¾inches. Most of the stairs are framed during construction and are computed without the finish floor in place, which is why we just compute the subfloor in the computations.
The landing at the top of a flight of stairs does not compute as a stair “tread”. There is often one additional riser than stair tread because a flight of stairs starts up with a riser and ends with a riser.
