1. 0:24–0:56 Understanding Tread Depth and Nosing From How to Measure Stair Tread Depth and Nosing Overhang, Step 1: Measure Stair Tread Depth

   The video uses a 3D animated model of a staircase to demonstrate how tread depth is measured. Starting with a 9-inch tread, it shows that while the structural tread might be 9 inches, additional length can be gained through nosing (an overhang). The presenter references the '2024 International Building Code - 1011.5.2 Riser Height and Tread Depth' to emphasize that these dimensions are governed by regulations. Examples are shown where adding an inch makes it a 10-inch step, and adding an additional 1.5 inches results in an 11.5-inch step. A warning is displayed: 'Long Nosing Can Create Trip Hazards', indicating that excessive overhang can compromise safety.
