  • Personal Preference: Ultimately, personal preference plays a role in determining the ideal overhang. Some individuals prefer a larger overhang for greater foot clearance, while others prefer a smaller overhang for a more streamlined look.

Recommended Overhang for Optimal Comfort and Safety

While the IRC provides minimum and maximum limits, a nosing overhang of 1 inch to 1 ¼ inch is generally recommended for optimal comfort and safety. This provides ample foot clearance while maintaining a safe and visually appealing step.

Trends in Staircase Design

  • Open Risers: Open riser staircases, which have no vertical riser between the treads, often utilize a slightly larger overhang to provide a visual cue and prevent the foot from slipping through the open space.

  • Floating Staircases: Floating staircases, which appear to have no visible support, often feature a minimal overhang to maintain their sleek and minimalist aesthetic.

  • Illuminated Nosing: Incorporating LED lighting into the nosing of stair treads is a growing trend, enhancing safety and adding a modern touch.

Conclusion

The overhang, or nosing, of a stair tread is a crucial detail that impacts both functionality and aesthetics. By adhering to building codes, considering factors such as tread material and staircase design, and aiming for an overhang within the recommended range, you can achieve a staircase that is safe, comfortable, and visually appealing.
