Channel letters are very commonly used to make illuminated signs. In the non-lit version, aluminum sheets are fabricated into individual letters and logos without installing LEDs. The letters are installed with screws or stud mounted into the wall – often with spacers. These signs are more expensive than acrylic or dimensional letters but have an extended lifespan of 20+ years. They also offer the most dimension at 4-5 inches thickness for increased visibility.
What Is A Dimensional Letter?
A dimensional letter or logo is not flat, meaning it has a visible thickness. If made from solid PVC, acrylic or metal, the sign letters are individual pieces mounted directly to the building surface. The amount of dimension, thickness, or depth is related to the viewing distance and is either a recommendation made by your sign company or based on requirements of the sign program of your building or city.
