SPAN/LOADING NOTES. Deflection limited to L/360 live load & L/240 total load. Spans based upon a stair limits of 8 max rise and 9 min. run, governing building codes may be more restrictive. Contact National Lumber EWP Engineering for design. assistance on other stair stringer applications and/or loading.
Adjust the height until the height and steps balance out (since you can't have a half or quarter of a step). Take the number of steps and multiply that by 10.5 inches (266.7 mm). That gives you the length of stair stringer necessary. Take that length and project it out from the deck. Now you have the location for the footing of the stair. 3. Lay out the steps on the stringer, using 2 x 12-inch (50 x 304 mm) treated wood, with a framing square. Set the riser for the height determined by your math and the step by 10 inches (250 mm).
