From on site measurements to your plans to machining on your CNC in minutes!

A brief overview of our StairDesigner software

  • Flexibility

    Build straight, spiral, curved and u shaped stairs, and those that incorporate winders and central cut strings, and lots more. StairDesigner can be used for wood, metal or stone stair building. Added functionality for wood and marble parts covering concrete stairs.

  • Fast

    A very quick and easy stair design calculator: add your staircase dimensions which in turn automatically calculate the staircase to meet building regulations.

  • Easy and Safe

    The software utilises a set of powerful algorithms to determine then optimise the strings and positions of the steps and their shape. This allows you to design turning stairs with winders with confidence. You can also include cut and boxed strings, straight, wreathed and curved.

  • Automatic calculations

    For all parts of your stair: the steps and risers, the string boards, spindles, handrails and newel posts. Then output the cut list and plans. You also have the option to print full size part by part templates to use as workshop mark ups for cutting and machining. Plus DXF export functionality for use in CAD/CAM programs and with your CNC router.

  • Excellent 3D Presentations

    Generate great 3D models incorporating wood or any other textures with lighting and transparency.

  • Save Big on Time and Money

    Intuitive to learn and use. Combined with the way StairDesigner accurately calculates the stair for you, massively speed up production time and eliminate errors when designing and marking up.

Intuitive Workflow That Mirrors Real Life

A few of StairDesigner's features

  • Stairwells & Flights

    Manages up to 7 flights in a single stair project. Ability to calculate helicoidal and spiral stairs. Set variable angles between flights, and for first and final steps.

  • Automatic Calculations & Verifications

    Immediately calculate step height, the going and the treadline. Verify H, G, and treadline parameters, providing minimum and maximum values. Quick wizard feature that will optimise flight length and the number of steps. Also balusters are optimised automatically for both cut and closed string boards.

  • Balancing Function

    The step balancing feature for step and stringer optimisation. This is a completely parametric and works on any shape of stair, and on fixed steps and groups of steps.

  • S Shaped Stairs and lots more

    Any shape of stair can be drawn with StairDesigner with up to 7 flights, each at any angle, with any turn, and with its own unique set up specifications. This enables management of S shaped stairs as well as L and U shaped stairs, and any other shape.

  • Steps & Risers

    All steps can be repositioned individually. All the specification for each step can altered, so that includes the recess, overlap, thickness and material.

  • Strings, Newel Posts & Handrails

    Full control of curved, wreathed, straight, cut and closed stringers. Parametric management of newel posts, balusters and handrails.

Example of a stair built with StairDesigner

1. Design and calculate your stair in StairDesigner

On site dimensions are input into the software, in this case for a quarter turn stair with winders. StairDesigner calculates the stairs, optimises the number of steps, step height and going and draws the plan.


30 minutes design time

2. Generate the 3D model and print different 3D views

StairDesigner automatically builds the 3D model. You can view the model in all its details to verify the design and export different views for commercial documentation.

3. Workshop drawings and folder

Once the stair has been created, automatic generation of a workshop document complete with a plan of the entire stair and individual plans of each part.

      Hi Kev, thanks for your query. StairDesigner works with steel stairs. Please go to our website to download and test the software out. You can buy it or sign up instead for Premium Support which allows you to use the free version and receive your cut lists and plans. The first option is best for a workshop, the second for a one-off project. If you’ve got any technical questions, we’ve got a forum over at as well. All the best, Stefan
