Step 3 · Cut Stringers
Using the design dimensions from Step 1, mark the rise and run on two or more lengths of 2x12 lumber to create the step stringers. A common method is to use a framing square or a specialized stringer layout tool. Carefully cut along the marked lines using a circular saw or a jigsaw. The resulting cuts will form the 'toes' where the treads will sit and the 'backs' where risers would attach (though risers are often omitted on simpler designs). Ensure all stringers are identical.
