Step 6 · Plan for Nosing and Overlap

The nosing is the visible edge of the tread that extends past the riser. It should typically be between 1 inch and 1.5 inches. This overhang contributes to the overall tread depth. Ensure that the total depth of the tread, including the nosing, provides a safe and comfortable walking surface, and that the calculation from Step 5 correctly accounts for this.
