The best way is to re-cut new stringers out of plywood or something dry and stable (I've used 8/4 poplar but now prefer laminated plywood). (3), risers, measured as the vertical nosing-to-nosing distance, shall be of uniform height in any one f light , with a maximum tolerance of, I always have to do some type of modification to the stringers to get the stairs to go together correctly. 24 hours is even better. Remember, changing the overall slope angle will affect this tread nosing to skirt board top edge dimension. Both stairs that are too high and too low can result in a staircase that is uncomfortable to climb. To make the riser height uniform in the set of stairs, Revit automatically choose 10 as the actual number of stair steps. Click Annotate tabTag panel (Tread Number).

Once you set your story pole, all you need are a couple of levels and a sharp pencil to mark them out. Just be sure to scrape/brush off/vacuum rough stringers where blocking will be attached. Rise Length = Vertical distance between the stair and next stair. It can be tricky getting a good reference point, so think that through before you commit to the PL. Looks like in the picture the tread nosings are pretty consistently spaced down from the top edge of the skirt boards - can't really tell unless you set a long straightedge across the tread nosings, then you'll see which are low and/or high. The stair risers are the vertical pieces on the stairs. I was told by a building inspector once to add a step because I was 1/8" over the maximum stair rise on a two step set of stairs from a garage to a basement. I disagree with contributor A - solid 1" treads are that thick because they are spanning across the rough stringers and will carry a fair amount of weight/stress. Interesting that you picked up on a 1/4" flaw in height between two stair risers. The overall height is the distance from the floor or landing at the top of the set of stairs to the floor/landing at the bottom of the set of stairs. I think that if the width of stair is enough then you can break the stairs in half and then construct few extra steps as in the photo... sorry for the bad sketch. A finished stair can't vary riser height in runs within a stair. In your case, if you'd like a shallower but still-comfortable stair, you'll need to add one or more risers to what is currently designed, then adjust the tread depth (aka Run), staying within the yellow zone on the new graph at the end of the article. What exactly is the riser issue? Note: The tread/riser annotation cannot be added to a sketch-based stair.

Doing so will make the modified treads independent of modifications to the tread on the main stair settings. You won't get them perfect. Add/remove risers at the top end by control or or change the stair run's 'Relative Top Height' parameter in … The greatest riser height within any flight of stairs shall not exceed the smallest by more than 3/8 inch (9.5 mm). Only disadvantage is I have to make a plunge cut cutting from the back to front on one of the rough stringers because of blade to saw base orientation. Measure out how much total rise your stairs need. The stair riser height calculated from the stair's total rise and number of risers needed. If you can split the adjustment between the top and bottom stair risers by trimming the stringer top and bottom, you'll have just 1/4" or 0.25" of riser height variation (one at stair top and one at stair bottom) - thus minimizing the trip hazard risk of the uneven risers and the variation will be within standards. The riser shall be measured vertically between leading edges of the adjacent treads.

To modify these types, either go to Stair Type, or use TAB to individually select a run, landing or support. Floor to floor height differences should produce slightly different riser heights using the same stair type as long as the max riser height threshold isn't crossed by the number of risers … Maximum 7-3/4 inch stair riser height. Having a jig for the saw to ride on is pretty accurate, way more than the freehand method used to cut the rough stringers originally. See Moving Levels.

In your case, if you'd like a shallower but still-comfortable stair, you'll need to add one or more risers to what is currently designed, then adjust the tread depth (aka Run), staying within the yellow zone on the new graph at the end of the article.
