What is the formula for building stairs?
Determining the Rise
You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).
How do you calculate rise and run for stairs?
The Total Rise should be not larger than 151 inches (3835 mm) between landings or floor levels. Total Run [G] – The Total Run is the horizontal length of a stair stringer. It is equal to the number of treads multiplied by the typical Tread Depth [B]. Risers – the Step Height [F] is the typical height of each step.
Which is the easiest type of stairway to build?
Straight stairs tend to be the easiest to go up and down, or, ascend/descend, as we say in the industry. They are typically the easiest to build, however, this depends a lot on the level of detail in the design.
Can I use 2×10 for stair stringers?
Pressure-treated or cedar 2×10 or 2×12 can be used depending on the depth of the cut-outs you’ll be using. By code you will need a minimum of 3-1/2″ of material left on the stringer after the cut-outs and that area should also be free of large knots which would weaken the stringer.
Are stairs at 45 degrees?
For example, if you were crazy and built a staircase with a 12 inch tread and riser, then the angle of the stringer to the floor would be 45 degrees. A more common angle is about 37 degrees. You can achieve this if you build a staircase with a 7.5 inch riser and a 10 inch tread.
How many stairs do I need for 10 feet?
All staircases have one more riser than they do treads. This means you will have 13 treads for a total length of 130 inches or 10 feet 10 inches. You must also figure in a minimum three-foot landing or clear floor area at the bottom of the steps.
What angle should stairs be?
Stair codes and guidelines prefer an angle of around 37° for normal stairways (the green area in our illustration) and around 7° for ramps (the yellow area in our illustration). Steeper slopes or angles are permitted for stepladders in certain applications as you can see in the illustration.
What is code for rise and run of stairs?
(c) Rise and Run. (1) The rise of every step in a stairway shall be not less than 4 inches nor greater than 7 1/2 inches. (2) The run shall not be less than 10 inches as measured horizontally between the vertical planes of the furthermost projection of adjacent treads.
What is a comfortable stair rise?
A standard number of treads in a stair between first and second floors is 14. With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 — within the conventional ratio of 72 to 75 inches.
How long of a 2×12 do I need for stairs?
How to Use the EZ Stair Calculator. We suggest 10.5″ for 2×12 or 2 – 2×6 Treads. Treads may be cut to suit other widths.
Which type of stairs is best?

Which side is best for staircase?
Direction: A staircase must always be built in the western or southern part of the house. It should not be constructed in the north–east corner, as it is believed that a staircase here can lead to financial losses. In fact, a staircase in any corner except the western or southern corner is believed to lead to losses.
What do you call a staircase that turns?
Helical staircases are sometimes referred to as curved staircases as they lead you upstairs in a flowing arc. Helical staircases are a statement, often used as a main staircase or exclusive staircase. These stairs frequently consists of two rolled stringers, with the treads attached between them.
