Dimensional letters are a popular choice for businesses that want signage with depth, durability, and a clean, upscale appearance. Whether installed outdoors on a building face or indoors as part of a lobby sign or office branding system, dimensional lettering delivers long-term value and visual impact.
Custom Dimensional Letters for Santa Rosa Businesses
Dimensional letters are individually fabricated letters, numbers, or logos mounted directly to a surface. Unlike flat signs, they create depth and shadow that naturally draws the eye and elevates your brand presence.

Signal Signs and Graphics creates custom dimensional letters for a wide range of applications, including storefront signs, building signs, lobby signage, and interior brand features. Each project is tailored to your space, brand guidelines, and visibility goals.
Dimensional letters are often selected as an alternative to illuminated signage when businesses want a refined, architectural look that remains legible and professional day and night.
Storefront and Building Dimensional Letter Signs for Outdoors
Dimensional letters are frequently used for storefront signs and building signage because they provide strong visibility without overwhelming the architecture. Letter size, thickness, spacing, and finish are customized to ensure readability from the street while complementing your building design.

Depending on your location and visibility needs, dimensional letters may be:
- Mounted flush to the building façade
- Installed with spacers for a floating effect
- Paired with external lighting for enhanced visibility
Dimensional lettering is commonly used alongside other exterior signage elements such as building signs and monument signs to create a cohesive exterior sign system.
Interior Dimensional Letters and Lobby Signage

Dimensional letters are also an excellent solution for interior branding. Many Santa Rosa businesses install dimensional lettering behind reception desks, in lobbies, or as feature wall signage to reinforce brand identity.
Interior dimensional letters are frequently used as:
- Lobby logo signs
- Office identification signage
- Feature wall branding
- Conference room or department identifiers
Dimensional lettering integrates seamlessly with other interior signage such as lobby signs, office signs, and wall graphics to create a polished, professional environment for customers, clients, and employees.
