Dimensional signs are three-dimensional, individual characters or symbols that are used for signage. These letters are often made from materials such as metal, plastic, or foam and are designed to stand out from a flat surface. Unlike flat, printed signs, dimensional letters add depth and a tactile quality to the signage, creating a more visually appealing and distinctive appearance. They are commonly used for exterior and interior signage in businesses to display names, logos, or other important information.
