Signage design should focus on four key dimensions: functional positioning, visual communication, environmental integration, and long-term maintenance, to ensure both efficiency and safety in practical use.
Core considerations for signage design
Clearly Define Functional Priorities: Before designing, it's crucial to clarify the sign's core purpose-is it for wayfinding, information delivery, safety warnings, or brand display? Different functions dictate the design direction. For example, emergency evacuation signs require high-contrast colors and internationally recognized icons, while scenic area information signs can emphasize a combination of text and graphics for cultural expression.
Ensure Long-Distance Visibility: Appropriately determine font size, color contrast, and graphic proportions based on the installation location. Main road or high-altitude signs should use large fonts and simple graphics, avoiding excessive details that could hinder readability.
Scientific Font and Color Selection
Sans-serif fonts (such as boldface) are recommended for clear readability. Color schemes should follow cognitive habits: red for prohibition, green for passage, and blue for guidance.
Avoid using blue, which can suppress appetite, as the primary color for restaurant signage, unless the brand has a specific brand identity.
Materials Matching the Environment
Outdoor signage should use weather-resistant materials such as UV-resistant acrylic, stainless steel, or preservative-treated wood to prevent fading and deformation due to sun and rain. Wood and stone are suitable for natural scenic areas to enhance integration with the environment.
Scientific and Reasonable Installation Location
Signage should be placed where pedestrians' lines of sight naturally fall, avoiding obstruction. For example, intersection signs should be placed within 100 meters before turns to ensure drivers have sufficient reaction time.
Compliance with Regulations and Accessibility Design
Adhere to relevant national standards (such as GB/T 20501-2013 Public Information Guidance System Standard) and consider multilingual support, Braille signage, or voice prompt systems in hospitals, schools, transportation hubs, and other locations to enhance inclusivity.
