With the total vertical rise determined (173 inches) and the total number of risers known (24 risers for this staircase), use a calculator to divide the total rise by the number of risers. For example, 173 inches / 24 risers = 7.2083333 inches per riser (approximately 7 and 1/4 inches or 7.25 inches). This calculation provides the precise height for each individual riser to ensure uniformity across the entire staircase.
