But I'm not sure that 24" of step depth is the most comfortable stairway. Item #701414. What happens when people walk down 24" stair treads is that because the tread depth is too short to take that extra halting step some walkers try to step all the way to the tread nose with their descending foot from the stair above. So we need to change 3 of our 19 "steps" into platforms that are 42.3 + 11" = 53.3" in the direction of travel of the stairs.

Exterior Stairs Tread and Riser Ratio Watch out: As I know you realize since you asked the question, the trip and fall hazard to avoid is a sort of "mini step" that is just less than 4" in riser height but lacks sufficient run to avoid tripping. Halting-walk low rise steps & long or deep stair step design hazards: How to build low rise, easy to climb steps for seniors, children, or over long low slopes. Indoors, where we need to climb in a more restricted space, typical dimensions are 17-18cm riser height and 22-24cm tread depth.

Then knowing the size and number of treads; it was possible to work out the riser height. Design Guidelines: Exterior Stairs . If we make a "step" or more than one step if necessary, into a platform that is 36" long, we can comply even with strict code interpretations (since the shortest platform length in the direction of stair movement is 36"). On any given flight of stairs, all steps shall have uniform riser heights and uniform tread widths. Balance is easier to maintain on the level You will recall the 11 inches (279 mm) minimum for standard stairway tread depth.

The nosing is not a separate piece of wood; it is the short extension of the tread that hangs over the riser. For outdoor steps, the common formula for comfortable proportioning is 2(R) + T = 26” to 27”, where R = riser height (in inches) and T = tread depth (in inches). Risers can be too low and treads too long for comfortable use of the stairs; a riser that's 7 inches is considered an ideal height with a 10-inch wide tread. x 12 in.
