Walkline Tread Depth Requirements — Measure Depth and Check for Safety
Part of project
Winder Step Measurement · Step 4 of 5
In this video
Following the minimum narrow-point requirement, the video discusses the second critical code: a minimum tread depth of 10 inches at the walkline. The walkline for winder steps is typically located 12 inches from the smallest side of the stairway. The narrator uses examples to show how a winder step's depth, even if meeting the 6-inch minimum at the narrowest point, must also satisfy the 10-inch minimum along the walkline. Diagrams illustrate how certain designs might fail this walkline requirement if not adequately planned, emphasizing that the tread depth at the walkline can be longer but not shorter than 10 inches.
