What is the minimum stroke width, in inches, required for address identification characters?

The minimum stroke width of 1/2 inch for address identification characters is essential for ensuring visibility and legibility, particularly from a distance. This dimension is often dictated by building codes and standards that emphasize safety and effective communication for emergency services. Characters that are too thin may be difficult to read, especially under low visibility conditions or from a moving vehicle. By specifying a minimum stroke width, guidelines ensure that addresses can be quickly identified by firefighters, paramedics, and other emergency responders, which can be crucial in times of crisis. The 1/2 inch measurement strikes a balance between visibility and practicality, making it a widely accepted standard in various local and national codes.
