Are you designing a stair for your new house? Are you a professional or a contractor assembling stairs for your clients? Are you going to design stair for your new house? Or you are a professional or contractor assembling stairs for your clients? Visual Stair Calc will assist you with calculating basic stair parameters in a straightforward way, in many cases with just a single input.
