How far apart should metal stair stringers be?
You should start with one near the middle – this will keep the frames straight and the proper distance apart. Be sure the same amount of the plank sticks over each end (at least 6 inches). NOTE: 6 to 18 inches of plank can stick over each end of the stringers, but the stringers may not be more than 36 inches apart.
How do you measure for metal stair stringers?
How do I calculate a stair stringer?
- Start by finding the overall height that the staircase will be.
- Decide the height or “rise” you’ll want for each step.
- Divide the total height of the staircase by the height or “rise” you want for each step.
Do I need 2 or 3 stair stringers?
The number of stringers you need is a function of the width of the staircase and the tread material. Cut stringers can be spaced no more than 18 inches on center, so a 3-foot-wide staircase needs three stringers, and a set of slightly wider stairs (say 3 feet 6 inches) needs four stringers.
Can I use 2×12 for stair treads?
Stair treads may be made of a single 2×12, but are often made of two decking boards or 2x6s. A stringer is a wide board, usually a 2×12, that runs at an angle from the landing pad to the deck framing and supports the treads. The stair treads should be at least 36 inches wide.
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.

What are you using for stair stringers?
Stair stringers are most often cut from a single 2×12 stock board. Situate the tread arm of the square nearest to the end of the board. The tread arm is the one you’re using to indicate the run of the steps, while the riser arm will serve as a guide for marking the rise.
