What Thickness Should Acrylic Letters Be? A Practical Guide for Business Signage
A shop fascia sign does far more than display your business name. It helps create a first impression, reinforces your branding and plays an important role in attracting passing customers. One of the biggest decisions when designing a new shop front is choosing the right material. Different materials offer different levels of durability, depth and visual impact, so understanding the options can help you make the right investment. What Thickness Should Acrylic Letters Be? Acrylic letters are one of the most popular choices for business signage because they offer a clean, professional and versatile finish. They can be used for shop fronts, reception signs, office walls, window displays and branded interior features. One of the most common questions customers ask is: what thickness should acrylic letters be? The answer depends on where the letters will be installed, how large they are, how far away they need to be read from and what type of finish the business wants to achieve. A small reception sign does not need the same letter thickness as a shop fascia on a busy high street. Why Acrylic Letter Thickness Matters The thickness of acrylic letters affects both appearance and performance. Thinner acrylic can look subtle and refined, while thicker acrylic creates more depth and a stronger three-dimensional effect. Thickness also affects durability. If the letters are too thin for the size of the sign, they may look weak or feel less substantial once installed. If the letters are too thick for a small interior wall sign, they may appear bulky and out of proportion. From a production perspective, the thickness must also work with the artwork. Very thin strokes, delicate. serifs and small details can become difficult to cut cleanly, especially when the letters are being produced at a small size. This type of signage is closely related to our Flat Cut Letters service. 3mm Acrylic Letters 3mm acrylic is usually suitable for small internal signs, lightweight wall lettering and subtle branding applications. It can work well for office interiors, plaques, directional signs and small logo details where the viewing distance is short. However, 3mm acrylic can feel quite flat when used for larger signs. It does not create much depth, so it is best used when the design needs to look discreet rather than bold. For production, 3mm acrylic also needs careful artwork checking. Thin strokes and fragile details can become risky, especially on smaller letters. As a general rule, a minimum stroke width of around 5mm is preferred for acrylic letters. A 3mm stroke may sometimes be possible, but it depends heavily on the font, size and fixing method. 5mm Acrylic Letters 5mm acrylic is one of the most commonly used thicknesses for flat cut letters. It offers a good balance between clean appearance, practical production and cost efficiency. For many shop signs, reception walls and office branding projects, 5mm acrylic provides enough depth to create a professional finish without looking too heavy. It is also suitable for a wide range of colours and finishes, including gloss, matt and wet-coated finishes. On a shop fascia, 5mm acrylic letters can work well when mounted to an aluminium composite panel, sign tray or painted wall. For internal signage, it gives a more premium appearance than thin flat graphics while still keeping the design refined. This thickness is often a sensible starting point for businesses looking for a clean, modern result. 10mm Acrylic Letters 10mm acrylic letters create a noticeably stronger three-dimensional effect. They are suitable when the sign needs more presence, especially in reception areas, feature walls and premium retail environments. Compared with 5mm letters, 10mm acrylic feels more substantial and architectural. It is often chosen when the sign is part of an interior design scheme rather than simply a functional name display. For larger lettering, 10mm acrylic can help the sign look more proportional. It also casts stronger natural shadows, which can make the branding stand out more clearly against the wall or fascia. This thickness works particularly well with simple, bold letterforms. Delicate fonts can still be used, but the artwork must be checked carefully to make sure all strokes and joins are strong enough for cutting and installation. 20mm Acrylic Letters 20mm acrylic letters are used when a more premium and dimensional appearance is required. They create strong depth and are often selected for high-end retail, hospitality, office reception areas and branded feature walls. At this thickness, the letters begin to feel more like architectural signage rather than flat decorative lettering. The side profile becomes part of the design, so colour, finish and edge quality are especially important. 20mm acrylic can also be wet-coated to achieve specialist colours and finishes. This is useful when a brand requires a specific metallic, matt or satin effect. For larger shop front signs, 20mm acrylic letters can deliver excellent visual impact while remaining cleaner and more cost-effective than fully fabricated built-up letters. When to Choose Built-Up Letters Instead Acrylic letters are a strong option for many projects, but they are not always the best solution. If the sign needs greater depth, illumination or a more premium external appearance, built-up letters may be more suitable. Built-up letters are constructed with returns, giving them a deeper profile than flat cut acrylic. They can also be combined with LED illumination for halo-lit or face-lit effects, making them ideal for shop fronts, restaurants and evening visibility. For businesses comparing flat acrylic letters with deeper dimensional signage, the choice often comes down to budget, viewing distance and the level of impact required. This type of signage is closely related to our 3D & Built-Up Letters service. Internal vs External Acrylic Letters Internal acrylic letters are usually easier to specify because they are protected from weather exposure Reception signs, office wall logos and interior branding can often use 5mm, 10mm or 20mm acrylic depending on the desired appearance. External acrylic letters need more careful consideration. Shop fronts are exposed to weather, temperature changes, cleaning and everyday wear. The fixing method, substrate
What’s the Difference Between CMYK, RGB, Pantone, and RAL When Designing for Print?
When designing signage, choosing the right color system isn’t just a technical detail — it directly affects how your final sign looks in the real world. Whether it’s a vinyl graphic, illuminated sign, or painted panel, different. color systems behave very differently in production. Understanding when to use CMYK, RGB, Pantone, or RAL will help ensure your signage looks exactly as. expected once manufactured. CMYK – The Standard for Printed Signage CMYK (Cyan, Magenta, Yellow, Black) is the most commonly used color system for digital printing in signageproduction. This is the color mode used for: CMYK works by layering ink, which means colors are created through a mix of percentages rather than asingle solid tone. When to use CMYK in signage: Key limitation: Colors can vary slightly depending on printer, material, and finish (matte vs gloss), so exact color matching can be tricky. To see some of our past printed graphics, visit our full colour graphics page. RGB – For Screens, Not Physical Signs RGB (Red, Green, Blue) is used for digital displays, not physical print. It’s commonly seen in: RGB colors appear brighter and more vibrant because they are light-based, not ink-based. When to use RGB in signage: Important note: If you design signage in RGB and send it to print without converting, colors will often look duller or different. Pantone – Precision Color Matching for Branding Pantone colors (from Pantone) are used when color accuracy is critical, especially for brand consistency. Each Pantone color is a pre-mixed ink, meaning it prints as a solid, consistent color rather than a blend. Common signage uses: Why Pantone matters: Limitation: Pantone is not always used in standard large-format printing unless specified — it may need to be convertedto CMYK, which can cause slight differences. RAL – The Go To for Painted and Fabricated Signs RAL is a color system used mainly for painted finishes and powder coating, not printing. It’s widely used in: Each RAL color represents a physical paint standard, making it ideal for manufacturing. When to use RAL in signage: Why RAL is important: To see RAL-coated lettering in real projects, visit our 3D and built-up letters page. Choosing the Right System for Your Signage In real-world signage projects, these systems often work together: A well-prepared signage file will use the correct system depending on how each element is produced.
