When ordering custom signs, one of the most common questions customers ask is: Should I choose coroplast or foamboard?
Both materials are lightweight, affordable, and perfect for full-color printing but they serve very different purposes. If you’re trying to decide between coroplast vs foamboard signs, this guide will help you choose the right material for your project.
What Is Coroplast?

Coroplast (also known as corrugated plastic) is a fluted polypropylene material that looks similar to cardboard on the inside but it’s made of plastic.
Why Choose Coroplast Signs?
✔ Weather-resistant – Perfect for outdoor use
✔ Durable and impact-resistant
✔ Lightweight and easy to install
✔ Cost-effective for bulk orders
✔ Compatible with H-stakes for yard signs
Best Uses for Coroplast Signs
- Yard signs
- Political campaign signs
- Real estate signs
- Construction site signage
- Event directional signs
- Temporary outdoor advertising
If your sign needs to withstand rain, wind, or extended outdoor exposure, coroplast is usually the better option.

What Is Foamboard?

Foamboard (also called foam core board) is made of a polystyrene foam center sandwiched between smooth paper surfaces. It offers a clean, professional appearance and prints beautifully with vibrant colors.
Why Choose Foamboard Signs?
✔ Smooth surface for high-quality prints
✔ Lightweight and rigid
✔ Great for indoor displays
✔ Professional presentation look
Best Uses for Foamboard Signs
- Trade show displays
- Indoor promotional signage
- Presentation boards
- Retail POP displays

- Mounting graphics for events
Foamboard is ideal when your sign will be displayed indoors and appearance is your top priority.

Coroplast vs Foamboard: Side-by-Side Comparison

Which Sign Material Should You Choose?
Here’s a simple way to decide between coroplast vs foamboard:
- Choose Coroplast if: Your sign will be outdoors, exposed to weather, or installed in the ground.
- Choose Foamboard if: Your sign will be indoors and you want a smooth, high-end presentation look.
If you’re unsure, consider how long the sign will be used and where it will be displayed. Outdoor conditions demand durability while indoor displays prioritize appearance.
Why Businesses Love Coroplast and Foamboard Signs
Both materials are:
- Affordable for small and large runs
- Custom printed in full color
- Easy to transport and install
- Great for short-term promotions
From political campaigns to trade shows, these two materials cover most signage needs.
