Stair Stringers (7) Stair stringers form the backbone of a set of stairs. By code, stairs need to be at least 36 wide. Although it's usually possible to get away with just using two stringers, we recommend you add a third one down the middle. This extra stringer will ensure your stairs are exceptionally rigid.
Step 3. Measuring the stringers. 1. Set stair gauges on the framing square at the height of the rise and length of the run. 2. Hold the square at the corner of the plank, and mark the top step. 3. Slide the square along the plank and mark the next step. 4. Continue marking until you have your number of steps. 5.easuring the stringers. 1.
