Interior Stair Detail Drawing With Riser Tread Step Dimensions

This stair detail drawing is prepared in AutoCAD format and provides clear technical information for interior stair planning and construction. The drawing explains the stair step composition, where each step consists of a tread, which is the horizontal surface stepped on, and a riser, which is the vertical face between two treads. Standard riser heights are typically shown between 150 mm and 180 mm, and tread depths between 250 mm and 300 mm to ensure safe and comfortable movement. The stair detail drawing also includes stair width generally around 900 m,m along with step alignment and slope direction for accurate vertical circulation planning. This stair detail drawing helps architects and civil engineers design efficient and code-compliant stairways.

The AutoCAD stair detail drawing includes clean line work, accurate dimensions, and proper annotations that support easy coordination with floor levels and structural elements. It is useful for interior designers and builders who require precise stair-step details during execution. This stair detail with dimensions improves clarity on site, reduces drafting time, and ensures consistent implementation across residential and commercial projects, making it a reliable reference for professional architectural and construction documentation.
