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.
