Chose your staircase calculator
We will help you to calculate your staircase as if a professional would have done it for you, and it’s free
Our online stair calculator apps help thousands of people to assess convenience of the design of their staircase, to determine its safety, its main parameters and to visualise the construction. Building stairs is no longer a subject for professionals exclusively but something you can do yourself. And you can easily see your output thanks to our detail drawings and the 3D function.
Let’s get started
The procedure is simple.
- First, choose your staircase type. Decide if you want to calculate one with wooden stringers, with metal (steel) stringer(s) or a concrete staircase. Then see which staircase shape is appropriate for you. We offer calculators for those with turn like L-Shape or U-Shape (also called switchback or half-landing), winder or double-winder or even spiral and concrete staircases. We encourage you to try different shapes, since shape determines the convenience given your space parameter.
- Second, specify the width and height of the opening, stair length, the size of the steps and stairs in mm, the number of steps you desire and stringer thickness. The accuracy of the result depends on the correct measurement of your initial dimensions.
- Finally, press the button: Calculate.
In a second you will get your results. In case your staircase deviates from convenience or safety, solutions are offered. There are useful additional features such as
- a function to print the result,
- visual assessment of the design in 3D,
- detailed drawings required for construction,
- calculation of building materials and building structures.
Our apps could also be used as stair rise and run calculator. This is because apart from calculating overall dimensions of a staircase, you will also get such outputs as: stair tread, stair stringer, deck, riser, angle and many more. These outputs are available for all 16 staircase types. These apps can also be used as ez stair calculators.
