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. All you need is to set the total rise which is usually the floor-to-floor height. This will trigger the calculation, display results and create a straight stair based 3d preview of the selected result. Key benefits: - Set the total rise to get valid combinations of number of risers and riser height. They are calculated automatically based on filter values. - Adjust the run within a valid range while controlling resulting stair angle and 2H+S rule (2xRiser + Run). - Set value ranges for riser height, unit run, 2H+S and stair angle to filter calculation results according to stair building codes or just your needs - Switch instantly between units: centimetres, millimetres, fractional or decimal inches - Adjust unit precision - Professionals can switch calculation mode to round riser values. Last remaining riser will be adjusted to match the total rise. - Check visually your stair with textured, shadowed, straight stair 3d-model of the selected result. Watch it from different points of view, zoom in/out, rotate or move. - Choose from traditional wooden stair or modern steel baluster structure model - Turn landings on/off - Check space requirements with dimensions - Switch to full screen mode for cleaner screenshots - Check integrated help for quick overview of the app features Privacy policy: This App does not collect nor process any personal data.
