📐 Staircase Design Elements and Dimensions
The image highlights the rise (height) and run (depth) of the individual steps, as well as the dimensions of the main landing/platform and the lower steps.
1. Individual Steps (Treads and Risers)
Riser Height (Rise):
Dimension: 18 cm
Definition: This is the vertical distance from the top of one tread to the top of the next tread. This dimension is crucial for comfort and code compliance.
Tread Depth (Run):
Dimension: 30 cm
Definition: This is the horizontal depth of the step where you place your foot. It's measured on the lower section of steps shown.
2. Staircase Sections
Main Landing/Platform:
Dimension: 1.30 m (Length/Depth)
Definition: This is the large, level section where the staircase turns or pauses before continuing upwards. This depth is important for traffic flow and safety.
Lower Steps (Width/Length):
Dimension: 1 m
Definition: This appears to be the width or length of the lowest few steps/platform area.
⚠️ Important Points/Considerations
Uniformity: In good stair design, the riser height (18 cm) and tread depth (30 cm) must be uniform throughout the entire flight of stairs. Inconsistency is a tripping hazard.
Building Codes: The dimensions shown (18 cm rise, 30 cm run) should comply with local building codes, which often specify minimum run and maximum rise for residential and commercial spaces. A common rule of thumb for comfortable stairs is that the sum of two risers and one tread should be between 60 cm and 64 cm (the 2R+T rule). In this case: 2(18 cm)+30 cm=36 cm+30 cm=66 cm, which is slightly above the ideal range but still generally acceptable.
Visual Design: The design suggests a floating or cantilevered aesthetic with a clean, modern, white finish, contrasting with the dark outline and warm wood floor.
Handrail: Although not dimensioned, for safety and code compliance, a handrail would typically be required on the open side of this staircase.
Is there anything specific you would like to calculate based on these dimensions, such as the total rise of the staircase or the total horizontal space it occupies?
