Setting Up The Framing Square
We use the framing square to layout the stair stringers. The length of the tread is on the right side of this picture which we'll set up at 10 inches on the framing square. The riser is on the left-hand side which we will set up at 7 15/16 inches. As you can see on the right next to the 10 inch we have already drawn our first step. In the picture below we are using stair guides to help us with accurate tread and riser layout.
