Dimensional letters are individual, non-illuminated letters and logos cut from metal, acrylic, or foam and mounted to a wall or panel for a clean, three-dimensional look. 303 Sign Company designs, fabricates, and installs dimensional lettering for lobbies, storefronts, and building exteriors across Northern Colorado.


Brushed or painted aluminum and stainless for a durable, premium interior or exterior look.

Cost-effective, crisp edges, and any brand color — ideal for lobbies and reception walls.

Precisely CNC-routed to your logo and typeface, with flush or stud-mount installation.
Most are cut from aluminum, stainless steel, acrylic, or high-density foam. We recommend the material based on where the sign lives, the look you want, and your budget.
No — these are non-illuminated. If you want illumination, channel letters or a halo-lit version are a better fit, and we build those too.
We use flush, stud, or standoff mounting depending on the wall and the look. Our crews install with commercial-grade fasteners for a secure, level result.
