Planning and Measurements

  1. Determine the Sign Dimensions: Measure the available space on the building façade or where the signage will be displayed. Decide on the appropriate size for the channel letters, considering visibility and aesthetic appeal.
  2. Font and Style Selection: Choose a font that aligns with the business branding and complements the overall design. Consider the readability and legibility of the selected font.
  3. Letter Face Material: Opt for high-quality acrylic sheets for the letter faces. Acrylic is available in various colors, thicknesses, and finishes, allowing for customized and vibrant signage designs.

Creating the Letter Faces

  1. Acrylic Sheet Cutting: Use precision cutting tools, such as a CNC router or laser cutter, to cut the acrylic sheets into the desired letter shapes based on the chosen font and dimensions.
  2. Polishing the Edges: Smooth the edges of the cut acrylic to achieve a clean and polished appearance. This step ensures the letter faces are ready for assembly.

Building the Channel Letter Profile

Preparing the Channel Letter Cans

  1. Selecting the Material: Choose aluminum or stainless steel for the channel letter cans. The material provides structural support and stability to the letters.
  2. Measuring and Cutting: Measure and cut the metal sheets into strips to form the sides (returns) of the channel letters. The width of the strips will determine the letter depth.

Assembling the Channel Letter Cans

  1. Bending the Letter Returns: Use a letter bender or letter bending machine to create precise bends in the metal strips. Ensure the corners are accurately formed for a seamless appearance.
  2. Welding or Bonding: Join the ends of the letter returns together using welding or bonding techniques. Welding provides a sturdy and permanent connection, while bonding with adhesives is an alternative for a seamless look.
  3. Attaching the Backplate: Attach a solid metal backplate to the channel letter can, providing stability and support for the letter faces.

Illuminating Acrylic Channel Letters

Front-Lit Channel Letters

  1. LED Modules: Measure and cut LED modules to fit the interior of the channel letter cans. LED modules are energy-efficient and provide bright illumination.
  2. Wiring and Electrical Connections: Securely fasten the LED modules to the backplate and route the wiring through the channel letter can. Connect the LEDs to a power source, ensuring proper electrical connections.

Back-Lit Channel Letters

  1. Backing Material: For back-lit channel letters, use a translucent acrylic or polycarbonate sheet as the backing material. This material allows light to pass through, creating a halo effect.
  2. LED or Neon Lighting: Choose either LED modules or neon tubing for the backlit illumination. LED modules are energy-efficient, while neon tubing provides a classic and vibrant appearance.

Installation of Acrylic Channel Letters

Mounting the Channel Letters

  1. Surface Preparation: Ensure the installation surface is clean and smooth. For wall-mounted signage, mark the letter placement accurately.
  2. Securing the Channel Letters: Use appropriate hardware and mounting methods to secure the channel letters to the installation surface. Follow local regulations and guidelines for safe and secure installation.


Crafting acrylic channel letters is a meticulous process that combines artistic design, precision manufacturing, and thoughtful illumination techniques. These visually striking and durable signs enhance the brand visibility and aesthetic appeal of businesses, making them a favorite choice in the world of modern signage. By understanding the step-by-step process of creating acrylic channel letters, sign fabricators can master the art of crafting brilliance and deliver captivating signage solutions to their clients. Whether front-lit or back-lit, acrylic channel letters continue to illuminate the path to effective and engaging brand communication.
