Stair tread depths shall be 11 inches (279 mm) minimum. The riser height shall be. measured vertically between the leading edges of adjacent treads.
A standard number of treads in a stair between first and second floors is 14. One hundred-five divided by 14 equals 7 1/2 . That means the distance from the top of each step to the top of the next step will be 7 1/2 inches. With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 -- within the conventional ratio of 72 to 75 inches. With 14 10-inch treads, the total run of the stair will be 140 inches.
