Custom Backplate Size Table
Custom Backplate Sizing for Signs: House Numbers, Business & Lobby Signs
Achieve the perfect framed look for any custom sign with our backplate sizing guide and options. A correctly sized backplate ensures your lighted house signs, 3D letters, or business logos look balanced and professionally installed.

Standard Sizing: For most custom signs—including popular illuminated house number signs, wall mounted business signs, and office signage—we recommend our standard size. The backplate is cut to be one inch larger on each side than your entire design, creating a clean, one-inch border or margin.
Full Customization Available: We specialize in custom signage. You can easily customize the backplate size to be larger based on your specific aesthetic preference, architectural space, or visibility needs for applications like outdoor house signs or large format lobby signs.

Popular Applications for Custom Backplates:
Lighted House Signs & LED House Number Signs
Custom Address Plaques and Modern House Numbers
Wall Mounted Business Signs & Lobby Signs
Outdoor Building Signs and Storefront Signage

Thank you for choosing BacklitLedSign for your personalized signage needs. Our signs are designed with low voltage for safety and come with easy-to-follow templates and an installation guide to help you set up your sign without any hassle.
If you decide to go with individual letters or numbers for your sign, please be aware that each letter or number will have a wire attached. It's important to ensure that your wall can be drilled to allow for the concealment of these wires. If drilling is not an option, we can provide a backplate to neatly cover the wires and maintain the aesthetic appeal of your sign.
