My deck stair photo at left shows very deep notching in a stair stringer as well as multiple other safety hazards and code violations.
Stair stringer size lumber.
As for the length of the stringers take the total height the stairs need to be and square that value.
Instead level over approximately to where the bottom of the stair will land step 1 in the illustration above the vertical distance between the bottom and top of the stair opening is distance x which in.
In a set of stairs 36 inches wide there are typically three stringers one on each end and one in the middle.
Start by figuring out how high the stairs will climb and how much.
The stringer length is the tip to tip length of the cut stringer.
Pros recommend a width of 16 between stringers but depending on the stairs and the thickness of the tread that figure could be slightly higher.
It is used to determine the length of 2x12 material required to build the stair stringer.
Risers are attached to the vertical cuts and treads are nailed to the horizontal cuts.
Less than 2 of lumber was left in this stair stringer 2x after the builder cut his tread notches.
But don t just measure up from below the top landing point.
Find the total rise of the stair the first measurement to determine is the distance between the top and bottom of the stairs.
When using pressure treated lumber use screws approved for use with acq.
Cleat brackets see details for correct usage.
Stringers cut to the proper dimensions are essential for building a solid set of stairs.
The lumber is pressure treated protecting it from termites and rot.
Measuring and cutting stair stringers for your own diy deck or porch project may seem complicated but the process is actually quite simple.
Hold up stair treads with this 3 step stair hold up stair treads with this 3 step stair stringer that meets the highest grading standards for strength and appearance.
Stringers are cut from framing lumber 2 by 8 2 by 10 in the profile of the stair.
Ideal for a variety of applications including decks docks and other outdoor projects where lumber is exposed to the elements.
Tired of making multiple trips to the store.
