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.

Where will the sign be displayed?

Indoor and outdoor environments often require very different materials.

How long will the sign be used?

A temporary event sign may need a different solution than a permanent building sign.

How important is appearance?

Premium interior displays often prioritize aesthetics, while construction signs may prioritize durability and cost.

What conditions will the sign face?

Wind, sunlight, moisture, temperature fluctuations, and traffic all influence material selection.
