9' vs 10' ceiling - Fine Homebuilding
For me, 10 is the run for stairs, and 7-3/4" the max rise. I will do anything I have to do, to keep it to that. I prefer stairs down closer to about a 7.4 rise, but that is me, with my 62-year old legs.

How many stairs do you need to go up 10 feet? - Quora
Answer (1 of 5): How many stair treads do you need for 10′ rise? Depends on the run. Run/rise ratios determine the maximum height you can have between treads to meet safety codes. If it's a permitted project that will be inspected, the building codes for your area will determine your min/max rise...
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 many risers can you have on a utility staircase?
For buildings other than private homes, you can only have 16 risers for utility stairs, or 12 for fire escapes (16 in exceptional circumstances where there is a restricted amount of space). There should not be any single steps and each riser should be the same height.
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)
How many steps are there in a flight of stairs?
Most flights of stairs average out at 12 or 13 steps but it depends on the height of the staircase, the location of the stairs (as stair height regulations differ between public and private buildings and between countries), and the purpose of a staircase (as fire escapes have more specific rules than other sorts of stairs).
What happens if you have too many stairs in a flight?
If there are too many stairs (or steps) in a single flight (without being broken up by landings) it can be tiring to walk up, disorientating to walk down, and if there’s a fall, increases the risk that there will be a serious injury. Too few and the staircase will take up significantly more space, as well as being slower to ascend and descend.
How many RISERS are needed for 30 degrees?
I have done just one calculation for 30 degrees which requires 15 Risers at 162.5 mm. And x = 45766. The angle is acceptable and so is the Standard Number for x. Try calculating for 32 degrees. It may also be acceptable.
What is a flight?
A flight is a continuous series of stairs between landings. If there are too many stairs (or steps) in a single flight (without being broken
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.
How high should a handrail be?
Similarly, handrails must be between 34 and 38 (96.52) inches high measured from the top of the treads, with a diameter between 1.25 inches (3.18 cm) and 2.675 inches (6.79 cm). Stringer: A stair stringer is a structural member that supports the treads and risers of a staircase.
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 wide should stairs be?
Stair width does not include handrails. Building codes generally suggest that stairs be at least 36 inches (91.44 cm) wide.
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.
What is a guardrail?
Handrails & Guards/Guardrails: A handrail is a railing that runs up a stair incline for users to hold when ascending or descending a staircase. A guard is "a building component or a system of building components located near the open sides of elevated walking surfaces that minimizes the possibility of a fall from the walking surface to the lower level." Guards can include rails (guardrails), but can be any number of other constructions such as walls, half-walls, or even a bench.
How deep should a stair tread be?
Treads - the Tread Depth [B] should not be less than 10 inches (254 mm). In a given run of stairs, the greatest tread depth should not exceed the smallest by more than 3/8 inch (9.5 mm). Typically, a single 2x12 or two 2x6s are used for stair tread material.
How many stringers are there on a set of stairs?
In a set of stairs 36 inches wide, there are typically three stringers (one on each end and one in the middle). The stringer length is the tip-to-tip length of the cut stringer. It is used to determine the length of 2x12 material required to build the stair stringer. Total Rise [A] - The total rise of a set of stairs is ...
What is a stair calculator?
The stair calculator is used for calculating stair rise and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. For convenience and flexibility, this stair stringer calculator comes in two forms, the automatic and manual . Click on the [?] icons to determine the best calculator to use for your stairs.

Stringer - The stringer is the structural part of a set of stairs. They are cut from 2x12s or larger material - the uncut portion of the stringer should not be less than 5 inches (127 mm) (see diagrams below). In a set of stairs 36 inches wide, there are typically three stringers (one on each end and one in the middle).
What is the height of the first step?
Height of First Step [E] - The the actual finished height of the first step is the same as the Typical Step Height [F], but when you cut the stair stringer, the First Step Height [E] is always the Step Height [F] minus the Tread Thickness [C].
What is the total rise of stairs?
Total Rise [A] - The total rise of a set of stairs is the vertical distance between the bottom of the first step and the top of the finished landing. The Total Rise should be not larger than 151 inches (3835 mm) between landings or floor levels.
