Design of Staircase Calculation – How to Calculate Rise and Tread Dimensions: While planning any stair important dimension to find out first that is rise and tread of stair and their numbers. Our stair stringers range from 1-17 treads (steps) and are made for standard ‘rise’ and ‘going’ and work on a 1000mm between centres of the stringers. For concrete stairs, select Concrete Thickness and enter the throat thickness (see diagram) and Stair Width to calculate formwork dimensions and concrete volume. Decide if you want to calculate one with wooden stringers, with metal (steel) stringer (s) or a concrete staircase. For wooden stairs, select Stringer Width and enter the width of the stringer. The optimum angle ranges from 30° to 40°. A minimum width between handrails of 1000mm.
