Signage Design Principles Every Graphic Designer Should Know
Signage Design: Functional and Visually Appealing
Signage is one of the most visible and impactful forms of branding in the physical world. Unlike digital or print design, signage must be legible, clear, and effective in real-world environments, often from a distance or in various lighting conditions.
For graphic designers, understanding the nuances of signage design is essential to creating signage that not only looks great but also serves its intended purpose effectively.
In this blog, we’ll explore key signage design principles every graphic designer should know to ensure their designs are both functional and visually appealing.
At Butler, we specialise in creating high-quality signage solutions that reflect your brand and enhance your visibility in any setting. Whether you’re designing for indoor or outdoor environments, understanding these principles is crucial for translating your graphic design skills into the world of signage.
Simplicity and Focus
In signage design, simplicity is key. Unlike digital media, where users can take their time to digest information, signage needs to communicate quickly and clearly, often in just a few seconds.
- Less is more: Avoid cluttering the design with unnecessary details. Focus on the most important information that the audience needs, whether that’s directional signage, a business name, or a promotional message. A clutter-free design improves legibility and ensures your key message is not lost.
- Prioritising key messages: Use size, colour, and placement to guide the viewer’s eye to the most critical information first. For example, on a retail storefront sign, the brand name should be the most prominent element, followed by the call to action or tagline.
Understanding the Environment
When designing signage, one of the most important factors to consider is the environment in which the sign will be placed. The location of a sign significantly influences its design. For instance, signage in a high-traffic outdoor area requires a different approach compared to signage in an office or retail space.
- Outdoor vs. Indoor signage: Outdoor signs need to be durable, weather-resistant, and highly visible from a distance, while indoor signs can often focus more on aesthetics and refinement. Outdoor signage is typically larger, with simpler messaging to ensure readability, whereas indoor signage may contain more details and finer design elements.
- Surroundings: The surroundings also play a role. Will the sign be viewed against a busy urban backdrop, or in a clean, minimalist office space? Graphic designers must account for how the environment interacts with the design.
Legibility and Readability
A sign’s primary function is to communicate a message, and legibility is critical to achieving this. The font choice, text size, and colour contrast all need to work together to ensure the message is clear.
- Font choice: Sans-serif fonts are generally easier to read at a distance, particularly for outdoor signage. Avoid overly decorative fonts, which can be difficult to read. Bold, simple fonts are usually the best choice for ensuring your message is immediately clear.
- Text size and hierarchy: The text size should be proportionate to the viewing distance. As a rule of thumb, every inch of letter height can be read from 10 feet away. Establish a clear hierarchy with large, prominent headings, and smaller text for secondary information.
- Contrast and colours: High-contrast colours (e.g., dark text on a light background or vice versa) are essential for readability. For example, white text on a black background is far easier to read than pastel colours or low-contrast combinations. Always ensure that the brand colours don’t compromise the clarity of the signage.
Scale and Proportion
When designing for signage, scale is essential to ensure that the sign is visible and readable from the necessary distance.
- Size matters: Large spaces require larger signs, and the design elements should scale appropriately. A small font or intricate details may work well on a business card or flyer, but they’ll be lost on a large billboard or outdoor signage.
- Designing for visibility: Ensure that all elements of the sign—text, logos, and imagery—are scaled appropriately. A general rule is that the main text should be at least 1 inch tall for every 10 feet of viewing distance.
Material and Finish Considerations
The materials used for signage affect both the design and the longevity of the sign. Different materials behave in different ways, so graphic designers must take this into account during the design process.
- Durability: For outdoor signage, materials like aluminium, stainless steel, and acrylic are commonly used due to their durability and resistance to the elements. Designers need to consider how these materials will hold up over time, especially in outdoor environments.
- Texture and reflectivity: Different finishes, such as matte, gloss, or powder coating, affect how the signage looks in various lighting conditions. Reflective materials might be harder to read in direct sunlight or under artificial light, so consider the impact of texture and lighting when choosing materials.
Branding and Consistency
One of the most important aspects of signage design is ensuring that it aligns with a brand’s identity. Your signage needs to be consistent with your other branding materials, whether it’s your website, print collateral, or packaging.
- Consistency across platforms: Ensure that the signage reflects the brand’s overall identity. This includes using consistent fonts, colours, and logo placements to ensure brand cohesion across all touchpoints.
- Colour matching: Accurately reproducing brand colours on physical signage can be challenging, especially when working with different materials. It’s important to ensure that the colours used in your signage match your brand colours as closely as possible. At Butler, we specialise in colour matching across various materials and finishes to ensure your brand identity remains consistent.
Incorporating Accessibility
Designing signage that is accessible to everyone, including people with disabilities, is crucial. Accessibility is not just a legal requirement—it also ensures that your signage can be understood by all.
- Accessible design principles: Use high-contrast colours and clear, legible fonts to assist people with visual impairments. Consider incorporating tactile elements or Braille signage where appropriate, particularly in public buildings or workplaces.
- Regulatory compliance: In the UK, the Equality Act 2010 mandates that public spaces accommodate individuals with disabilities. This means that signage should comply with standards like BS 8300-2:2018, which outlines best practices for designing accessible environments.
Lighting and Illumination
Lighting can dramatically enhance the visibility and impact of signage, especially in low-light or outdoor environments.
- Considering lighting in signage design: Think about how lighting will affect the visibility of your signage. Is the sign placed in a dimly lit area? Will it need to be visible at night? These factors will affect design choices.
- Types of illumination: Options such as halo lighting (backlit for a soft glow), face illumination (lighting from the front), or side lighting can add dimension and ensure your sign stands out in low-light environments. The choice of lighting depends on the effect you want to create and the environment in which the sign will be placed.
Conclusion
Designing signage requires a different approach compared to digital or print design. By considering factors like environment, legibility, scale, material, and accessibility, graphic designers can create signage that is not only visually appealing but also effective in communicating its message.
