Straight Single-Flight Staircase

Information

A straight single-flight staircase featuring robust diagonal stringers enhances the vertical accent of any room while optimizing space, even in compact private houses. Its refined design is complemented by extended railing rods that ascend gracefully toward the upper opening, securely anchored to the first-floor ceiling.

When positioned flush against a wall, the straight single-flight staircase to the second floor occupies minimal space. The combination of the base step and landing creates a distinctive and welcoming entry area, allowing the staircase’s starting point to be efficiently set in corner spaces with solid walls.

This state-of-the-art online calculator for a straight staircase to the second floor not only evaluates the functionality of your stairway but also offers detailed insights into the fabrication of stringers and treads. With precise measurements provided, you can efficiently craft the structural elements using wood or metal, all without incurring expensive professional costs.

Features of this calculator:

This interactive online tool is designed to help you choose the optimal structural solution for one of your home’s most essential design elements—the staircase.

This calculation program provides you with the following benefits:

• Evaluates the ergonomic comfort and feasibility of the staircase
• Determines the precise dimensions of the floor opening
• Calculates the ideal angle of inclination required for safe and smooth movement
• Estimates the quantity and dimensions of materials needed for your project
• Generates essential production drawings for both manufacturing and installation

Data used to assess the convenience of a straight staircase:

Utilizing this free online calculator for designing a single-flight straight staircase requires no specialized expertise. Simply follow the straightforward guidelines and let the tool handle the rest.

• The optimal inclination angle for the staircase stringers is between 30° and 40°; any deviation from this range can compromise both comfort and safety when moving between floors.
• The recommended tread depth for optimal walking comfort ranges from 27 to 32 cm. If maintaining this measurement is not possible, consider a slight adjustment by adding a modest overhang, which should not exceed 5 cm.
• Also, keep in mind the "average step length" parameter: the sum of the widths of two treads and the combined height of two risers should equate to an average stride, not exceeding 63 cm.

Essential preliminary data

For the most accurate calculation of your straight single-flight staircase, start by determining several critical measurements: the exact floor height, the width of the stair flight, the available space within your interior layout, and the junction point with the floor. You might need to explore multiple options before selecting the optimal solution.

This user-friendly and free online calculator allows you to experiment with various configurations and obtain production-ready drawings for your staircase in a private residence.
