1m2 Stairs Dimensions
A common US residential standard suggesting a 7-inch ( ) riser and 11-inch ( ) tread.
Therefore, a 1m² footprint forces you into compact configurations: , alternating tread stairs , or ladder-style stairs . A standard straight flight cannot exist in 1m² because it would require steps too steep for safe use. 1m2 stairs dimensions
The defining feature of this staircase is its unique angled central column, which allows for a smaller circumference than standard spiral stairs without sacrificing usability. Footprint: ), though it can be adjusted from Floor-to-Ceiling Height: Typically designed for heights between 2.3 m and 3.5 m , but it can be configured for ranges as low as or as high as Approximately on average, depending on the chosen height and width. Materials: A common US residential standard suggesting a 7-inch
A typical residential staircase (90 cm wide) with 17 steps, 18 cm riser, and 25 cm tread occupies about of floor space. A 1m² staircase is therefore ~74% smaller. To achieve that, you cannot reduce width below 60 cm (building codes). So the only variable left is the step geometry and layout . The defining feature of this staircase is its
With perfect spiral geometry, 1m² works if you accept a narrow 60 cm walkline.
A is an ultra-compact access solution, not a comfortable primary stair. It works best for reaching a sleeping loft, storage mezzanine, or rarely used attic. The alternating tread design is the most practical for this tiny footprint, but always check your local building code before building. When in doubt, sacrifice a few more decimeters of floor space to create a safer, more usable stair.
This guide explores everything you need to know about designing stairs for a 1m² footprint.
