2-Step Pressure-Treated Pine Stair Stringer is rated 3.9 out of 5 by 152. Rated 2 out of 5 by Rix from Not a great buy Like a lot of projects I do I bought 6 stringers knowing that I would only need 3 or 4.
Stringers, typically cut from 2 x 12s, are the sloped boards that support the other components and carry the weight of people walking on the stairs. They're typically spaced 16 in. on center.
The sawn stringer fits under the stair treads and therefore cannot extend above the treads as with a solid stringer. The 3-5/8 inches lower mounting position versus the solid stringers is due to the sloping geometry of the stairs and only valid for a 7-3/4 inch riser.
If you follow the directions in this how to build stairs story, your stairs will be legal and safe. In a nutshell, treads should be more than 9 in. deep and risers 6-1/2 to 8 in. high. Riser heights can vary no more than 3/8 in. from one step to another to reduce trip hazards.
Stair treads may be made of a single 2x12, but are often made of two decking boards or 2x6s. A stringer is a wide board, usually a 2x12, that runs at an angle from the landing pad to the deck framing and supports the treads.
Stair stringer layouts seem challenging, but in this video Wayne Lennox shows how to build them in a simple fashion. What projects should we make next?
When building stairs or steps for a deck: Make sure all of the step risers are the same height, and all the step treads the same width to avoid a tripping hazard. The rise of each step is determined by the height of the landing from the ground, with each step height from 7″ to 8″ high.
Stairs with more than three steps should be built using stair stringers. The first step is to measure the height of the stairs to determine the number of stairs you need to build. The maximum riser height is 8" and the minimum tread depth is 10".
I don't see many deck stairways built with bracketed stringers, but they're a good alternative to notched stairs in certain situations. The design is similar to housed stringers--where dadoes are routed into the framing to provide shoulders for the treads and riser boards to rest in--but is simpler to build.
How to Build Deck Stairs You normally don't give much thought to building a set of deck stairs. But, when the time comes, you should check out Internet sites for advice or attend a DIY clinic at your local home improvement store.

Stairs can span up to 7’ wide with only two stringers. No center stringers are needed because the riser is code approved as a load-bearing joist, providing steps of superior strength. In addition, skilled saw cuts that have been traditionally required are now drastically eliminated leaving only 3 to 4 cuts per stringer.
The sides of the stairs, or stringers, are cut from 2-by-12 boards. Using a framing square, mark out the portions to be cut away from the stringer. Starting at the top corner of the board, place the square so that one leg is 7.46" (the rise) and the other is at 10” (the tread) .
For example, if you are building stairs to go up to a deck, and you measure 3 feet (0.91 m) from the ground to the top of the deck, then this is the total rise. If you want the stairs to stop 3 inches (7.6 cm) from the top of the deck, however, count the total rise as 2.75 feet (0.84 m).
Exterior wooden decks are built in a variety of styles. Most decks require only one or two steps to lead from the ground floor level of a home to the yard below.
Deck stairs are typically made from 2 x 12 stringers spaced about 12 to 16 inches apart. They rest on a solid foundation and are attached to the deck with hangers. They have risers (also called toe kicks), treads and railings.
Figure 2. Use a laser level and a tape to accurately measure the total rise between the landing and the top of the finish decking. Like floor joists or rafters, stringers of a certain size and spacing can span only so far, depending on the type of stringers (cut or solid) and the species of wood.
The hanger board will only support the right stair stringer due to the alignment with the concrete step, and the 2×10 beam will support the left stringer.
