What Size Does Plywood Sheets Come In?

In the wood industry, plywood sheets come in various sizes to suit different project needs. While manufacturers may produce custom sizes, there are standard plywood sheet sizes that are widely used and readily available in Canada.

The most common standard size for plywood sheets in Canada is 4×8 feet (1220×2440 mm), which is versatile enough for most construction and woodworking projects.

However, other sizes like 5×5 feet (1525×1525 mm) and 8×4 feet (2440×1220 mm) are also popular for specific applications. These measurements are typically given in both imperial and metric units, reflecting Canada’s use of both systems.

Widths and Lengths

While the standard 4×8 ft (1220×2440 mm) sheet is most common, plywood comes in various widths and lengths to suit different project requirements. In addition to the sizes we offer (5×5 ft, 4×8 ft, and 8×4 ft), some manufacturers produce sheets in sizes like 4×10 ft (1220×3050 mm) or even larger custom dimensions. The choice of width and length often depends on the specific application, with larger sheets being useful for expansive projects and smaller ones offering easier handling and transportation.

How Thick is Plywood?

Plywood thickness is another crucial factor to consider when selecting sheets for your project. In Canada, plywood thicknesses typically range from 1/4 inch (6 mm) to 1-1/4 inches (32 mm), with common increments including 3/8 inch (9 mm), 1/2 inch (12 mm), 5/8 inch (16 mm), and 3/4 inch (19 mm). The thickness you choose depends on the structural requirements of your project, with thicker plywood generally offering more strength and stability. It’s important to note that actual thicknesses may vary slightly from the nominal size, so it’s always best to check the exact specifications when planning your project.

Nominal Thickness (inches)Metric Equivalent (mm)Common Uses
1/46Underlayment, drawer bottoms
3/89Roof sheathing, siding
1/212Subflooring, sheathing
5/816Flooring, heavy-duty sheathing
