staircase design software

Windows 7, 8, 10 or above - 8 GB RAM recommended, 16 GB if you're working on large and complex projects

Graphics card: DirectX compatibility required which almost all cards have. We recommend the card has a minimum of 4GB memory, or 8GB for larger projects.

Mac: we have many Mac clients successfully using our software with a Windows Emulator. Please see our FAQs page for details.

Please note: near the end of the install process, you will be asked to activate your software to unlock the full set of features. You can skip this step unless you have purchased the full version.

The free/demo version includes all design functionality. The only thing it doesn't do is output the manufacturing documents like the cutting list and plans (sample files are available at the bottom of this page).

The installer will copy the library files onto your desktop into this folder:

Your desktop\stairdesigner

Important: the new install will overwrite all files in desktop\stairdesigner if it already exists.

If you are updating previous Quick Design Libraries that you have customised, and you want to keep the old libraries, you must rename the old libraries folder before installing the updates.

Please also note: you must be using the latest version of StairDesigner to use the latest version of the libraries. Simply click on the StairDesigner download button on this page to install the latest version.

StairDesigner Quick Design Libraries: a powerful catalogue of materials and manufacturing methods to help you build faster and better.

The libraries are delivered as examples; we advise you to test and adjust them to your manufacturing methods before using them for production. Consider our Libraries Set Up service to tailor them to your specific needs.

Getting Started Videos

1. Create a New Stair

Select a new stair from the list of models, and set up general dimensions and parameters, and add components like the strings, handrails and newel posts.

2. General Stair Parameters and Optimisation

How to display and modify the general parameters of your stair, including adjusting the number of steps to optimise riser height, tread width and meet the Stair Rule.

3. Modifying Winders

Winders are tapered steps, so their edges are not parallel to each other. In most European countries, these winders are tapered gradually into and out of the turn. It makes for a safer stair but it takes more time to build. In the UK for example using winders just around the turn is an acceptable way to build stairs. This method makes the staircase easier and faster to build.

We see here how to modify which steps are winders, which are not, and how to adjust the tightness of the turn. We also look at how to manually adjust each winding step so it is as easy to manufacture as possible (not too close to the edge of the newel post for example).

4. Multi Flight Stair Mode: Straight Flights

In this video we will use the multi flight option to create a series of straight flights. This offers a lot of flexibility in how we can design its shape. You can add multiple flights, modify length, height and width, adjust the angle between each flight and edit the angle of the first and last steps.

5. Multi Flight Stair Mode: Circular Flights

How to use the Multi Flight Stair Mode to create a curved stair of one or more curved elements. Each element can be edited in detail to allow you a lot of flexibility in your project design.

6. Adding Landings

How to add a landing in StairDesigner. You can either open up one of the pre-configured stair models that includes a landing (quarter turn, half turn and stairs with arrival landings), or add a landing to a project you're already working on. Its possible to accurately adjust the its height, length, width and angle, and independently optimise the flights above and below the landing.
