Page top stair dimension sketch courtesy of Carson Dunlop Associates. We also explain now to include landings and platforms in stair design calculations.įinally, we also explain how to adjust factory-built or pre-fab stairs to the exact stair rise dimension in your installation. This article includes example stair building calculations and warns about some "in between" stair tread sizes that may be a trip/fall hazard.
We also describe how to design and build low-slope or low angle stairways with special consideration for tread and landing dimensions to avoid halting-walk stairs and other trip hazards. We describe how to translate the stair rise and run into a specific number of stair treads and risers that will be uniform and of proper (safe) dimension. We explain how total elevation change between two levels or floors (rise) and stair length (run) are used to calculate the right measurements when building indoor or exterior stairs to fit the building or the terrain.ĭetails of methods for accurate stairway rise & run measurement are provided for tough cases such as building a stair over steep slopes and irregular surfaces. Here using simple arithmetic we explain how to make stair design calculations: number of steps, step riser height, total stair height or rise, total stair length or run.
