Cardboard sheets are flat panels of paper-based board used for crafting, packaging, and DIY projects. On this page you’ll find two common types:

• Chipboard: solid pressed paperboard (often 22 pt, 30 pt, or 40 pt) used for scrapbooking, photo mats, notepad backing, tags, and project bases.
• Corrugated cardboard: a fluted core with liners (e.g., B flute) used for packaging inserts, mailing pads, model building, and protective layers.

They come in various sizes (from small 3 x 5 to larger 32 x 40), colors and finishes (kraft brown, white, black, assorted colors), and multi-pack quantities. Choosing the right type depends on how much rigidity, cushioning, and surface finish your project needs.

You can shop a wide selection of cardboard sheets online and check local store availability on each product page. To narrow your options, use filters and product details to compare:

• Size: from small formats (3 x 5, 5 x 7, 8.5 x 11) to larger panels (11 x 17, 20 x 12, 27 x 19, 32 x 40).
• Type: chipboard (measured in points) or corrugated (flute types like B flute).
• Color/finish: kraft, white, black, or assorted colors.

At checkout, choose shipping, pickup, or delivery if offered. Selection and fulfillment options can vary by location and time, so it’s helpful to enter your ZIP code to see what’s available near you.

Both are useful, but they’re built differently and shine in different jobs:

• Chipboard: a single, dense paperboard sheet measured in points (e.g., 22 pt, 30 pt, 40 pt). It’s smooth and great for scrapbooking, photo mats, notepad backing, gift or product tags, and other flat projects.
• Corrugated cardboard: a fluted core sandwiched between liners (look for B flute). It adds rigidity and cushioning, making it a fit for packaging inserts, mailing pads, model building, and layered crafts.

If you want a smooth surface and slimmer profile, chipboard is a practical pick. If you need more structure and protection, corrugated sheets are worth considering.

The right size depends on your project and how much trimming room you want:

• Small crafts and backing: 3 x 5, 5 x 5, 5 x 7, or 8.5 x 11.
• Portfolios, signs, or bigger layouts: 11 x 17, 20 x 12, or 27 x 19.
• Displays and large projects: oversized panels like 32 x 40 or long strips such as 36 x 8.

Measure your artwork or item, then pick a sheet slightly larger to allow for clean edges. Also review thickness—chipboard points (22–40 pt) or corrugated flute type—so you’re balancing size with the rigidity your project calls for.

Cardboard thickness is described differently by type:

• Chipboard: measured in points (pt) or caliper. Listings often show both together (for example, 30 pt ≈ .030 inch). Higher points generally indicate a stiffer, heavier sheet suited to backings and covers.
• Corrugated cardboard: identified by flute profiles (e.g., B flute). The flute type influences rigidity and cushioning; product details typically note the flute so you can compare options.

Choose a thickness that aligns with your use—lighter boards for easy cutting and layering, heavier boards for stability or protection. Reviewing the specifications can help you find a good balance for your project.
