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 [? If you have any questions, please Contact Us. 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 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.

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 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 inches mm between landings or floor levels.

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.

Open risers with openings more then 30 inches mm vertical to the floor should not permit the passage of a 4-inch-diameter mm sphere. Treads - the Tread Depth [B] should not be less than 10 inches mm. Typically, a single 2x12 or two 2x6s are used for stair tread material. If the Stinger Mount Type is Flushthen the number of risers is the same as the number of steps.

Stringer Position [H] - The stringer position refers to how far below the finished height of the upper landing the stringer will be attached. Headroom - the headroom should not be less than 6' 8" mmmeasured vertically what is antivirus security pro the stair tread nosing to the nearest ceiling object. It can also be useful for cutting the angle on the top of the stair rail pickets. Stringer Length - the stringer length calculation is the minimum length of 2x12 material that is required to layout and cut the stringer.

Stairs and Landings - Landings are used to break up runs of stairs. Building code states that the minimum width of a landing should not be less than the width of the flight of stairs that is served.

Using a few modifiable default settings, the automatic calculator will compute all of the other factors, including the Total Run [G].

The Total Rise [A] is the finished height of your landing or deck. The Target Step Height [F]is the height that you would like your steps to be. The automatic calculator will design your stair stringer as close to the target height as possible, while maintaining a common step height. Follow the steps below to design your stair stringer:. The results will appear in the Results section of the calculator and on the Stair Diagram below.

The Stringer Mount Type refers to how the stringer will be attached to the upper landing or deck frame. Once the stair results have been calculated, you can toggle between the Standard and Flush options to compare the differences.

The first time you enter a value in the Number of Steps field, it will likely be a guess. If the numbers are too high, add some more steps. Once the stair results have been calculated, you can toggle between the Standard and What is the atomic mass of the element options to compare the results.

Deck Stair Stringers Spacing

Align the rise and run measurements on the square with the edge of the stringer. This will establish the starting point for the stringer. Trace out the Unit Rise and Unit Run as shown by the measurements on the square. Extend the horizontal line across the 2x The calculator will provide you with the number of stairs, riser height and tread depth to cut your stringers. You will need to remove the thickness of the riser board from the top stair and remove the thickness of the tread board from the bottom stair. You can now draw the notches for the stairs onto your 2x12 stair stringers. Nov 05,  · There should be at least 5 in. of stringer stock left at the back after cutting the notches. Using 2?12 stringer stock and a in. run barely leaves 5 in., and a bigger run would leave even less. After you’ve decided the rise and run, lay out the stringer with a framing square. .

By clicking GO! After talking to many deck builders over the years, we have found that stair construction is considered the most difficult part of building a deck. In order to lay out the stairs, you need to measure the exact height of the deck from the top of the decking to the location where the stairs are going to land on the ground.

You can input this number into our Stairs Calculator on Decks. The calculator will provide you with the number of stairs, riser height and tread depth to cut your stringers. You will need to remove the thickness of the riser board from the top stair and remove the thickness of the tread board from the bottom stair. You can now draw the notches for the stairs onto your 2x12 stair stringers. The load supporting requirements for stair treads are more severe than for the rest of the deck because the force exerted by a person walking downstairs is a more intense blow to the surface than a standard stride across a level surface.

Always check the maximum span for your decking material as it applies to stair treads. Always read the composite decking installation instructions for stair treads before building your stairs. It is best policy to overbuild your stairs because of the increased wear and tear they often receive. Pay particular attention to the stringer placement if you are attaching stairs around a corner, as in the case of a cascading staircase. Determine the total rise for your stairs using a level and a tape measure.

Measure the distance from the top of the deck surface to the top of the stair landing. Input the total rise number into the Decks. The above example shows outside drop-mounted stairs.

Using the information from the Decks. After laying out your rise and run measurements on your 2x12 stair stringer, remove 1" from the back of the top run if you plan on installing a 1" thick riser board. The cut line is in red.
