Divide the height of the staircase in inches by the intended rise of each step, also in inches, to assist in determining the stair stringer length. The riser height is up to you, though most building codes will not allow a height larger than 7 3/4 inches.
The following analysis demonstrates results of a typical wood-framed stair stringer configuration as well as several similar configurations. Consider 15 risers at 7Â¼-inch tall with 10Â½-inch wide treads and stringers cut from SPF No. 1/No. 2 2x12s. This configuration results in an effective throat depth of approximately 5 inches for a horizontal span of 12 feet and 3 inches.
