How can I use a framing square to help build steps? How can I use a framing square to help build steps?
To build steps using a framing square, you must make two marks on the outside of the long side and the outside of the shorter leg. The mark on the longer leg, or the blade, determines the distance between risers (the heights of each stair), while the mark on the outside of the shorter leg, the tongue, determines the height of each step. Place the long edge of the square on the top edge of the stringer, or the support piece, for the stairs and mark the length. Then, draw a line down the shorter blade to the second tape mark. Continue until you reach the end of the stringer.
