Every DIYer has a secret weapon: and more often than not, it’s plywood. Strong, smooth, and endlessly adaptable, this humble sheet material has earned its place as the backbone of countless builds. From stylish shelving to sturdy cabinetry, from wall panels to workbenches, plywood gives your ideas structure and staying power. It’s easy on the budget, kind to beginners, and versatile enough to keep even the pros coming back. But with so many sizes and thicknesses to choose from, how do you know which one’s the right fit?  Whether you’re crafting furniture or tackling a home improvement project, knowing your way around a plywood board is essential. Start by exploring BUCO’s plywood selection and see what options are available.

When you walk into a timber shop, plywood sheets can look intimidating—they’re big, flat, and come in multiple thicknesses. Here’s the breakdown so you know exactly what to pick:

Standard Sheet Size

Most sheets come in 2440mm x 1220mm. This large size works well for walls, cabinetry, furniture panels, and even subfloors. Cutting it down to smaller pieces is straightforward with the right saw and clamps.

Thickness Options

• 3.6mm: Ideal for lightweight backing, drawer bottoms, or decorative panels.

• 6mm: Great for small shelves, craft projects, or wall panelling.

•  9mm: Often used for furniture backs, lightweight worktops, and cupboard doors.

• 12mm: Strong enough for standard cabinet panels, shelving, or partitions.

• 18mm: Perfect for load-bearing applications like flooring, workbenches, or heavy-duty shelving.

Pro Tip: Always consider the sheet thickness relative to the weight it will carry. Thinner sheets are easier to handle but may flex under heavy loads. For cabinets or shelves, 12mm or 18mm usually strikes the right balance.

Picking the right plywood isn’t just about size, it’s about matching the board to the project and the intended load. Here’s what to think about:

• Load and Use
  Shelves, cabinets, or structural panels need thicker sheets for strength, while decorative wall panelling can get away with thinner plywood. Load and Use
• Finish
  Raw plywood is ideal for painting or staining. Laminated or treated sheets save time on finishing and provide moisture resistance for kitchens or bathrooms.
• Cutting and Edging
  Some plywood edges chip when cut. Use a fine-tooth saw and clamp the sheet securely. For exposed edges, edge banding or trim can give a clean finish.
• Screw-Holding Strength
  Thicker sheets hold screws better, preventing splits or wobbling. Pre-drilling pilot holes helps even with 18mm sheets.

BUCO’s Boards and Timber department is a great resource if you’re unsure which thickness or finish fits your project. Staff can advise on load capacity, cutting techniques, and finishing options.

Plywood and timber each have their strengths, and using them together often yields the best results.

• Plywood is stable, lightweight, and cost-efficient, making it perfect for panels, cabinetry, and internal structures. It resists warping better than solid wood in large flat surfaces.
• Solid Timber is stronger and more visually appealing, so it’s ideal for frames, exposed surfaces, or structural elements where durability matters.

Pro Tip: Combine both materials for balance. Use solid timber for edges and structural parts, and plywood for flat panels. This approach gives a polished, professional finish without breaking the bank.
