This online calculator facilitates the design of an L-Shaped Winder Staircase (Quarter-Turn Stairs) using innovative winder steps and a 90° turn to reach the second floor—no advanced architectural skills or specialized construction expertise required. Developed by seasoned professionals for practical application, this tool combines simplicity, ergonomic design, and an intuitive interface to help you complete complex geometric and construction calculations with just a few clicks. Simply follow our clear guidelines and industry standards to achieve precise material estimates and error-free technical drawings.
This versatile instrument delivers highly accurate computations for both wooden and metal staircases. Discover the essential aspects of constructing an L-Shaped staircase with integrated winder steps—a solution that not only ensures fluid movement between floors but also maximizes space efficiency compared to traditional straight staircases. The absence of a conventional landing, achieved through smart winder geometry, enhances both aesthetic appeal and cost-effectiveness by reducing material usage in intermediate areas.
To design your L-Shaped Winder Staircase with a quarter-turn, please input the following essential specifications:
Attention should be paid to critical features such as the rise height and effective tread depth to ensure a safe and optimal design.
For the winder steps, consider these recommended measurements:
Maintain the riser height within the standard range of 15–20 cm, and ensure the stringer is inclined at an angle of 30–40 degrees for comfortable movement. It is essential to consider the specific properties of your chosen material—whether wood, metal, concrete, or glass. Finally, do not overlook the nosing projection; for this staircase type, the overhang should remain under 5 cm.
By adhering to these guidelines and accurately entering your specifications, you will obtain detailed design drawings of an L-Shaped Winder Staircase along with validated calculations that meet industry standards for safety and comfort.
The primary outcomes of this calculator include:
Using this information, manufacturers can produce the individual components that are later assembled into the final staircase construction.
Additional renderings illustrate the finished appearance of the staircase once the stringers and steps are connected.
A standout feature of this L-Shaped Winder Staircase calculator is its dual functionality:
Whether you choose a metal or wooden construction, our online calculator expedites computations and visualizes your staircase design. It takes into account all necessary dimensions and material characteristics to deliver a precise, reliable design for your L-Shaped Winder Staircase (Quarter-Turn Stairs).
