The ideal rise is typically between 6.5 to 7.75 inches (16.5 to 19.7 cm), while the ideal run is usually 10 to 11 inches (25.4 to 27.9 cm). However, these can vary based on local building codes and specific needs.
For a 9-foot (108-inch) ceiling, you'll typically need 14 to 15 steps, depending on the exact rise per step you choose.
It's strongly recommended to keep the rise consistent throughout the staircase. Varying heights can create a tripping hazard.
Most building codes require a minimum width of 36 inches (91.4 cm) for residential staircases.
Many building codes require a landing if the vertical rise exceeds 12 feet (3.66 m) or if the staircase changes direction.
