   Begin marking the tread and rise measurements onto the 2x12 board using a framing square. To save time and ensure consistency, attach stair gauges to the framing square to lock in your calculated rise (7 3/4 inches) and run (10 inches) measurements. Position the framing square near one end of the board, aligning the stair gauges with the edge of the board. Use a pencil to trace the outline of the first notch. Continue marking the remaining stringer notches, ensuring that each new notch begins at the point where the previous one ended. After marking all the steps, extend the final lowest tread line to the back edge of the board. This creates a straight edge where the stringer will meet the floor. This is also where you will factor in the thickness of your finished flooring. For example, if your finished stair treads will be 1 inch thick, mark a 1-inch thickness along the bottom of the lowest tread. This marked section will be trimmed off during cutting to ensure the stringer fits correctly and the bottom step has the appropriate height, accommodating the flooring.
