How wide must the contrasting color band on stair treads be?

The requirement for the width of the contrasting color band on stair treads is established to enhance safety and ensure visibility for users. A band that is 2 inches wide strikes an effective balance between being noticeable enough to alert individuals to the edge of the step while still maintaining an aesthetically pleasing design. This width is sufficient to be easily recognized by individuals, including those with visual impairments, thus minimizing the risk of trips and falls.

Using a width of 2 inches complies with safety regulations that aim to promote accessibility in public swimming facilities and other spaces. Wider bands, while possibly more visible, may not be necessary and could interfere with the overall look of the stair treads. Similarly, narrower bands might not provide adequate visual cues, leading to potential safety hazards. Therefore, adhering to the 2 inches requirement is essential for both safety and visual clarity.
