Kelly FirthIntroduction
When it comes to woodworking projects, one of the most crucial materials you’ll encounter is plywood. Whether you’re working on furniture, cabinets, or any DIY project, the type of plywood you choose can significantly impact the outcome. However, selecting the right plywood is not always a straightforward task, especially for beginners.
Many newcomers often make avoidable mistakes, leading to wasted time, money, and suboptimal results. This guide will help you avoid 7 common mistakes beginners make when choosing plywood, ensuring your next project is a success.
Mistake 1: Ignoring Plywood Grade
Why Plywood Grade Matters
The plywood grade is one of the most important factors in choosing the right material for your project. Plywood is available in different grades, and understanding these grades will help you select the best option based on your needs.
For instance, high-quality plywood (Grade A) is ideal for furniture building and projects where the surface will be visible. On the other hand, lower grades may have visible knots and defects, making them better suited for hidden or structural parts of your project.
Different Grades Explained
- Grade A: Best for visible surfaces such as furniture and cabinet making.
- Grade B: Has minor imperfections but still works well for projects with hidden surfaces.
- Grade C: Larger defects; good for non-visible applications like sheathing or subflooring.
- Grade D: Most defects; used in structural work or areas where aesthetics don’t matter.
Choosing the wrong grade can lead to a rough finish, affecting the overall quality of your work. Check out our guide on choosing plywood for more insights into how to pick the right grade for your project.
Mistake 2: Choosing the Wrong Thickness
How Thickness Affects Your Project
The thickness of plywood plays a crucial role in the strength, weight, and overall feel of your project. Plywood thickness ranges from 1/8-inch to 1-inch, and selecting the right thickness is key for your specific application.
When to Choose Thicker or Thinner Plywood
- 1/4-inch: Ideal for lightweight projects such as drawer bottoms or paneling.
- 1/2-inch: Perfect for furniture backs, cabinets, and shelving.
- 3/4-inch: Best for structural applications, such as subflooring or heavy-duty shelving.

Mistake 3: Failing to Consider Plywood Type
Understanding the Different Types of Plywood
There are two primary types of plywood: softwood and hardwood. Each type has its specific advantages, and choosing the right one can make or break your project.
When to Use Softwood vs. Hardwood Plywood
- Softwood Plywood: Typically made from pine or fir, softwood plywood is lightweight, more affordable, and easier to work with, making it great for framing, sheathing, and DIY projects.
- Hardwood Plywood: Made from oak, birch, or maple, hardwood plywood is denser, stronger, and more durable, making it ideal for fine furniture or high-end cabinetry.
Choosing the wrong type can affect both the strength and aesthetic of your project. Learn more about the different plywood types and their uses in our guide.
Mistake 4: Not Checking for Plywood Defects
Common Plywood Defects to Watch Out For
One of the biggest mistakes beginners make is overlooking defects in plywood. Plywood can have defects like knots, delamination, or warping, which can negatively affect both its strength and appearance.
- Knots: Can weaken the plywood and make it difficult to achieve a smooth finish.
- Delamination: Where the layers of the plywood begin to separate.
- Warping: Causes the plywood to bend or twist, especially in damp conditions.
How Defects Impact the Strength and Durability
Defects like knots or warping can make the plywood unsuitable for structural work. Always inspect the plywood carefully to ensure there are no major defects. For more tips on checking plywood quality, read our article on plywood protection.
Mistake 5: Overlooking the Importance of Finish
Why Finish Is Important for Plywood
The finish of plywood is vital in determining the final look and feel of your project. Whether you’re planning to stain, paint, or leave the wood natural, the finish you choose should complement your project’s overall aesthetic.
Types of Plywood Finishes
- Smooth Finish: Ideal for painting or veneering, as it provides a clean, sleek surface.
- Textured Finish: Adds a rustic or vintage look, perfect for wall paneling or decorative projects.
- Sanded Finish: Common for projects where the plywood will be left natural or stained, as it offers a smooth, uniform surface.
Choosing the right finish can significantly enhance the look of your project. For more on finishes and care, explore our wood care section for further tips.
Mistake 6: Not Considering Environmental Factors
Impact of Moisture and Humidity on Plywood
Plywood is sensitive to moisture and humidity, which can cause it to swell, warp, or rot over time. Depending on where your plywood will be used, it’s important to choose the right material for the environment.
Choosing Plywood for Different Environments
- Interior Use: Use interior-grade plywood for dry environments, such as furniture and cabinetry.
- Exterior Use: Opt for exterior-grade plywood that is specially treated to resist moisture, ideal for outdoor projects like decking or garden furniture.
Consider your project’s environment carefully to prevent long-term damage. For more about plywood in different conditions, read our plywood selection guide.
Mistake 7: Failing to Compare Prices and Quality
How to Balance Cost and Quality
While it’s tempting to choose the cheapest plywood, doing so can often lead to poor-quality results. It’s important to strike a balance between price and quality, especially for long-term or high-use projects.
Where to Find High-Quality Plywood at the Right Price
Research different suppliers to compare prices and ensure you’re getting the best quality at a competitive rate. Look for sales or bulk discounts for larger projects. You can find reliable vendors and discounts by checking out our buying guide for more tips.
Conclusion
Choosing the right plywood for your project doesn’t have to be overwhelming. By avoiding these 7 common mistakes, you’ll ensure that your plywood selection enhances the quality, strength, and aesthetics of your project. Whether you’re crafting furniture, building outdoor structures, or completing a DIY project, knowing the ins and outs of plywood will help you make the best choice.
