Foam core (often called foam board) is a lightweight display board made by laminating paper facers to a foam center. The result is rigid, smooth, and easy to cut for school, office, and craft projects.

• Common thicknesses include 1/8 in. and 3/16 in.
• Popular sizes include 20x30, 22x28, 24x36, and tri-fold 36x48.
• Surfaces may be white or black; some options are acid-free for photo mounting.

It’s widely used for presentations, signs, crafts, and mounting prints. Specific materials and finishes can vary, so reviewing each product’s description can help you match the board to your project and preferences.

In most cases, “foam core” and “foam board” refer to the same type of board: a foam center laminated with paper facers. Naming often varies by listing.

• “Poster board” is typically paper-only and thinner, so it’s different.
• You may also see PVC foam sheets or EVA craft foam; these are different materials intended for specific uses like modeling, cosplay, or signage.
• Helpful specs to compare: thickness, size, color (white/black), surface finish, and whether it’s acid-free.

When in doubt, check the product details to confirm the material and construction so you get what your project requires.

Shopping at Walmart is flexible, whether you prefer online or in-store.

1. Search “foam board” on Walmart.com or in the Walmart app.
2. Use filters for size (20x30, 22x28, 24x36), thickness (like 3/16 in.), color, pack count, or tri-fold.
3. Select the quantity you need and review photos/specs for surface and material details.
4. Check availability for pickup, delivery, or shipping; options can vary by location and item dimensions.

If you plan to visit a store, checking local inventory online ahead of time can help you decide which location has the sizes and formats you want.

Match the board to your project’s weight, look, and display needs.

• 3/16 in.: a sturdy, versatile choice for mounting prints and displays.
• 1/8 in.: lighter and easier to cut; useful for simple signage or layering.
• 20x30 or 22x28: good for classrooms, posters, and everyday projects.
• 24x36 or larger: more impact; consider extra support or an easel.
• Tri-fold 36x48: stands on a table for presentations.
• White vs. black: white for general use; black can frame photos and reduce edge glare.
• Acid-free: helpful when mounting photos or artwork long term.

Compare product specs, as rigidity and surface finish can differ by item.

These tips can help you get clean edges while working safely.

1. Use a sharp craft or utility knife with a metal straightedge.
2. Cut on a protective mat and clear the area underneath.
3. Score lightly first, then make additional passes—don’t force the blade.
4. Keep the knife vertical to reduce beveling; replace dull blades as needed.
5. Support the offcut near the end to minimize tearing or denting.
6. For curves, trace a template and cut slowly with shallow passes.
7. Cut away from hands and store blades safely after use.

Results can vary with thickness and surface coatings, so testing on a scrap piece is a practical way to dial in your technique.
