- It compares selected dimensions with references from IRC, IBC, ADA, and OSHA, while warning that local adoption and amendments vary.
Field notes
The worked example uses a 9-foot floor-to-floor height and displays 14 risers, 13 treads, and an 11-foot, 4½-inch run. Optional inputs let users account for nosing projection, tread-board thickness, and available space. Reference checks cite specific code editions, but the page says local adoption, amendments, and exceptions matter and does not treat the results as a compliance decision.
