Generally 180mm (7 inches) for residential and commercial steps.
: Draft the detail in model space at a 1:1 scale . Use paper space viewports to present the detail at a highly legible layout scale, such as 1-1/2" = 1'-0" or 3" = 1'-0" .
The stairs must also resist the required live loads: typically a concentrated load of 300 lbs or a uniform live load of 100 psf (40 psf for one‑ and two‑family dwellings). Deflection is generally limited to L/360 for live loads and L/240 for total loads.
