One of the most common questions people ask when ordering a sign is:
“What material should I use?”
The answer depends on more than the design itself. Where the sign will be displayed, how long it needs to last, weather exposure, installation requirements, and budget all influence which material is the best fit.
Here’s a guide to some of the most common sign materials and when they’re typically used.
Acrylic signs are often chosen when appearance is a top priority.
With a smooth surface and polished appearance, acrylic creates a modern, professional look that’s popular in offices, healthcare facilities, retail environments, and corporate spaces.

If you’re unsure which material is right for your project, start by asking four questions:
Indoor and outdoor environments often require very different materials.
A temporary event sign may need a different solution than a permanent building sign.
Premium interior displays often prioritize aesthetics, while construction signs may prioritize durability and cost.
Wind, sunlight, moisture, temperature fluctuations, and traffic all influence material selection.
| Material | Best For |
|---|---|
| Acrylic | Premium interior signage, lobbies, offices |
| Vinyl | Windows, walls, floors, vehicles, graphics |
| Mesh | Windy outdoor environments, fencing, large displays |
| Aluminum | Permanent outdoor signs, parking, safety, wayfinding |
| Coroplast | Temporary outdoor signs, events, campaigns, real estate |
There’s no single “best” sign material—only the material that’s best for your specific project.
Acrylic offers a premium appearance. Vinyl provides flexibility. Mesh handles wind. Aluminum delivers long-term durability. Coroplast provides an affordable solution for temporary signage.
