According to building practice, what is the minimum extrusion distance for letters or symbols on signs to public rooms?

• A. 0.5 mm
• B. 1 mm
• C. 2 mm
• D. 3 mm

Answer: (B)

The minimum extrusion distance for letters or symbols on signs to public rooms is set to ensure visibility and readability. An extrusion distance of 1 mm provides a sufficient tactile and visual distinction that enhances legibility for people navigating public spaces. This amount is generally considered a standard that balances practical usability with aesthetic considerations. Additionally, options with lower or higher extrusion distances would not adhere to commonly accepted standards for signage. An extrusion distance of 0.5 mm may be too subtle, compromising visibility, while distances greater than 1 mm might not be necessary, potentially leading to excessive protrusion that could detract from the sign's overall design or create obstacles in navigable areas. Thus, 1 mm is the optimal choice for clear, practical signage in public environments.
