How To Create Stair Nosing - Simplified Explanation For New Stair Builders


This video offers a simplified explanation of how to create a stair nosing, which is the overhang at the front of a stair tread. The process involves adding an inch or your desired overhang length to the width of the stair tread while maintaining the same 10-inch measurement for the tread run between risers.

Here's a step-by-step breakdown:

Measure Tread Width: Determine the desired width of your stair treads (e.g., 10 inches).

Add Nosing Overhang: Increase the tread width by the desired nosing length (e.g., 1 inch for a 1-inch overhang).

Maintain Tread Run: Ensure the distance between the front of one riser and the front of the next riser (tread run) remains consistent at 10 inches.

Adjust Top Landing: If your top landing has a finished edge, you might need to adjust its position by the nosing overhang length to maintain a level transition.

Consider Riser Thickness: If your risers are thicker than standard ( ¾ inch), factor in that thickness when positioning the stair stringer to achieve the correct tread run.

Bonus Tips:

Visualize with a Diagram: Draw a simple diagram of your stair layout to better understand the relationship between tread width, nosing overhang, and tread run.

Practice with a Model: If you're new to stair building, consider creating a small-scale model to practice laying out the treads and risers with the nosing overhang.

Consult Local Building Codes: Ensure your stair design complies with local building codes regarding tread and riser dimensions, as well as nosing overhang
requirements.

Consider Safety: A well-designed stair nosing provides an edge that prevents slips and falls. Choose a nosing size that offers adequate protection without being excessive.

Aesthetics: The nosing can be a design element. Consider its shape, size, and material to complement the overall style of your staircase.
