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.
1 Riser-Tread formula: Sometimes the stair parameters will be something like riser plus tread equals 17â18 inches (432â457 mm); another formula is 2 times riser + tread equals 24.6 inches (625 mm), the length of a stride. 2  Thus a 7 inches (178 mm) rise and a 10.6 inches (269 mm) tread exactly meets this code.he following stair measurements are important: 1  The rise height or rise of each step is measured from the top of one tread to the next. 2  It is not the physical height of the riser; the latter excludes the thickness of the tread. 3  A person using the stairs would move this distance vertically for each step taken.
