People often use a few names for a backing board, depending on the project. The most common terms you’ll see here include:

• Chipboard – a dense, pressed cardboard used for notepad backing, packaging, and crafts.
• Tagboard/Mounting board – similar uses, often describing smooth sheets for displays and photos.
• Corrugated cardboard sheets – fluted boards for larger, lightweight support.

These come in sizes like 8.5 x 11, 5 x 7, 11 x 17, and larger project sheets. Thickness is usually listed in points (pt), such as 22 pt (light), 30 pt (medium ~0.03 inch), and 40 pt (heavy). Color options often include kraft brown, black, and white.

Cardboard sheets can work well as backing for documents, photos, and crafts when sized and weighted appropriately.

• Match thickness to the task: 22 pt for light notepads and inserts, 30 pt for everyday craft and display, 40 pt when you want extra stiffness.
• Pick the right size: Common options include 5 x 7, 8.5 x 11, and 11 x 17. Larger pieces are available for posters.
• Consider corrugated: B- or E-flute sheets can add rigidity for bigger projects.
• Protect the surface: Slip your item into a sleeve and place the board behind it. Using tape on the outside edges of the sleeve can help avoid contact with your item.

For casual display or mailing, many shoppers choose smooth chipboard or tagboard for prints.

• Choose stiffness: Medium (around 30 pt) helps with small to mid-size prints; heavy (around 40 pt) offers more rigidity.
• Pick a finish: Kraft brown for a natural look, black for a polished presentation, or white for a clean, bright backing.
• Scale up when needed: For larger prints, consider corrugated sheets to reduce flex.
• Protect the art: Place the print in a sleeve and add the board behind it. For shipping, sandwich between two boards. Using gentle, removable tape on the outside of the sleeve can help keep things in place.

For a lightweight, decorative backing on shelves, cardboard options can be helpful, but they aren’t intended for structural support.

• Corrugated project sheets: E- or B-flute boards offer rigidity for larger spans and come in big panel sizes.
• Heavy chipboard: Good for smaller sections or to create a neat, uniform look.
• Measure first: Choose a sheet size that covers your shelf opening with minimal seams.
• Attachment: Removable, surface-friendly adhesives can hold panels in place, but results vary by surface and humidity.

If you need load-bearing reinforcement or long-term stability, cardboard may not be sufficient; consider solutions designed for furniture support.

A few simple steps can help you get neat, consistent cuts on chipboard and corrugated sheets.

• Use the right tools: A sharp craft knife, a metal ruler, and a cutting mat.
• Score, then cut: Make several light passes rather than one heavy cut for smoother edges.
• Mind the grain: On corrugated, cut from the smooth side and across the flutes to reduce tear-out.
• Support the edge: Keep firm pressure with the ruler to guide your blade.
• Finish carefully: Lightly sand edges or use a bone folder to tidy surface fibers.

Work slowly, keep hands clear of the blade, and test on a scrap before final cuts.
