01 / Input example
Example: a 3,600 mm finished floor-to-floor rise with 22 risers gives approximately 163.6 mm per riser. Tread count depends on flights and landing connections.
02 / Check assumptions
With a 280 mm going, Blondel’s 2h + b expression gives approximately 607.2 mm. This explores walking proportions; it does not certify code compliance.
03 / Scope of use
Also check headroom, flight width, landings, guarding and plan constraints using project documents and applicable requirements.
04 / Keep in mind
Open ArchStair to explore options. Supported stair types and export formats have not been verified by this central website.
Tool introductions do not validate algorithms or certify regulatory compliance. Guides are practical examples; design and construction decisions require checks against project documents, applicable rules and qualified professional judgement.
