Dimensional Letter Signs are a term used to describe a sign that is made by assembling three dimensional material raised from the background surface. These are typically a collection of letters, logos, graphics or phrases that, then displayed together, create a complete sign.

As you may have guessed, dimensional letter signs have a raised, three-dimensional appearance and are typically made from metal, aluminum or acrylic. They extend beyond the surface of the wall or building facade to create a distinctive shape and presence.

Dimensional lettering is one of the most versatile and effective signage options, and frequently used for business lobby signs, office reception signs, and retailer and commercial spaces. Whether your signage needs are exterior or interior, dimensional lettering offers a professional, sturdy and timeless appearance.

Materials Used in Dimensional Letter Signs


Acrylic is very affordable sign material and will hold up well to outside elements and temperature fluctuations. It comes in many colors, and can be cut, shaped and formed into different size signs for different needs. Acrylic is the most common type of plastic dimensional letter signs and can even be made to look like other materials at a fraction of the cost.

Sign manufacturers often turn to aluminum because it is a durable lightweight material. Aluminum is strong, does not rust, and offers an affordable material solution that can be used for numerous sign types and needs. It offers flexibility for design and style and will hold up well over time.

PVC / Dimensional Plastic

Similar to acrylic, painted dimensional plastic PVC letters are a very common form of dimensional letters use for exterior signage. It is tough and durable so it stands up to weather. PVC letters will range in thickness from 1/8” to 1” thick.  While PVC comes in many base colors, unlike acrylic, it can be painted virtually any color and finish.

Rigid Foam / High Density Urethane

Rigid polyurethane high-density foam is versatile, strong and durable. High density urethane (HDU)/ polyurethane foam board is commonly used in outdoor dimensional signage for carved or routed signs, usually as a substitute for wood. As with PVC, rigid foams are “closed cell” and do not absorb water.
