What is the minimum height letters on an exit sign must be?

4 inches
6 inches
8 inches
10 inches

The correct answer is: 6 inches

The minimum height for letters on an exit sign is established to ensure visibility and readability in emergency situations. A letter height of 6 inches is stipulated in safety standards because it provides clear guidance for individuals trying to locate an exit quickly, particularly in low-light conditions or areas filled with smoke. This size is effective for most viewing distances, ensuring that the sign can be read at a reasonable distance, which is critical during an evacuation scenario. Adequate signage plays a vital role in ensuring public safety, which is why the standards are set at this specific measurement.
