The Importance of Choosing the Right Plywood
The wrong choice of plywood can lead to unexpected project failures and added costs. Understanding the key features of plywood will help you avoid common mistakes and make a confident choice for your next project. Now, let’s explore the top 10 things you need to know about plywood.
1. Understanding Plywood Layers
Plywood is created by stacking thin sheets (called veneers) of wood at right angles to each other. This multi-layer construction gives plywood its strength, flexibility, and durability.
For a complete overview of plywood’s structural design, visit our plywood types page, which explains how each type of plywood is made and how it’s used.
What Makes Up Plywood?
The layers in plywood consist of an outer face veneer and a core of thinner layers or sheets of wood. The face layers are typically made of higher-quality wood, while the core layers can be made from less expensive wood.
How Layers Affect Plywood Strength
The number of layers and the type of wood used can influence the strength of the plywood. More layers usually result in stronger plywood, but the quality of the veneers and the glue used also plays an important role in determining overall strength.
2. Different Types of Plywood
Understanding the different types of plywood will help you pick the right one for your project. From softwood and hardwood plywood to marine-grade plywood, there’s a variety of options available for different needs.
Softwood vs. Hardwood Plywood
Softwood plywood (like pine or fir) is generally less expensive and used for general construction, while hardwood plywood (such as oak or birch) is stronger and more aesthetically pleasing. Hardwood plywood is perfect for fine woodworking and furniture projects.
To help you compare these materials, take a look at our DIY plywood buying guide, which offers expert advice on selecting the best plywood for your budget and project needs.
Marine Plywood
If your project will be exposed to moisture or water, marine plywood is a great option. It’s designed specifically to withstand humid and wet environments, making it ideal for boat building and outdoor furniture.

Decorative Plywood
For projects where the aesthetics of the plywood matter, decorative plywood is an excellent choice. It features a fine veneer surface that’s great for visible furniture parts, cabinetry, and interior decor.
Specialty Plywood
Some projects may require specialty plywood for specific uses such as fire-resistant, soundproof, or high-strength plywood. These are more niche options designed for unique applications.
3. The Significance of Plywood Grade
The grade of plywood refers to the quality of the wood and how well the layers are bonded together. It’s essential to know the plywood grading system to ensure you choose the best option for your project.
What Do Plywood Grades Mean?
Plywood grades range from A (best quality) to D (lowest quality), with each letter representing the appearance and condition of the wood used for the outer veneer. Grade A plywood is smooth and free of imperfections, while Grade D may contain more defects.
To learn about selecting the best grade for your woodworking project, be sure to check out our article on plywood grades.
How to Choose the Right Grade for Your Project
For projects where appearance matters, like cabinetry or fine furniture, opt for higher-grade plywood (A or B). For projects where the plywood won’t be visible, such as subfloors or hidden structures, Grade C or D plywood can work.
4. Plywood Thickness Matters
The thickness of plywood is an important factor when choosing the right material for your project. Thicker plywood is stronger and can handle more weight, making it ideal for structural applications.
How Thickness Affects Plywood’s Strength and Use
Thicker plywood provides more strength and stability, which is important for load-bearing applications. Thinner plywood is more flexible and typically used for non-structural purposes, such as decorative elements or crafting.
Common Thickness Sizes and Their Uses
Plywood thickness ranges from 1/8” to 1”, with common sizes being 1/4”, 1/2”, and 3/4”. For furniture, 1/2” or 3/4” plywood is ideal, while thinner plywood is used for cabinet backs and decorative panels.
5. Understanding Plywood Strength and Durability
When choosing plywood, it’s essential to consider its strength and durability. This depends on the core material and the quality of the wood layers.
The Role of Core Materials
The core of plywood can be made from solid wood, particleboard, or MDF. Solid wood cores offer more strength, while particleboard and MDF are cheaper options but less durable.
Strength Rating and Load-Bearing Capacity
Check the strength rating of plywood to ensure it meets the needs of your project. For load-bearing applications, such as floors or shelves, choose a higher-grade plywood with a higher strength rating.
6. Plywood Finish and Appearance
The finish of plywood affects its appearance and how it interacts with stains, paints, and other treatments. A smooth, finished surface is ideal for visible applications like furniture.
How Finish Affects Aesthetics and Functionality
The finish on plywood can enhance its aesthetic appeal, making it more suitable for visible projects. It also plays a role in protecting the wood from wear and moisture.

Selecting the Right Finish for Your Project
The right finish depends on your project’s use. For furniture and decorative pieces, consider varnishing or staining the plywood. For projects exposed to moisture, use a waterproof finish.
7. Moisture Resistance and Plywood
If you’re planning to use plywood in moist or wet conditions, moisture resistance is a key factor. Choose plywood designed specifically for high-humidity environments.
Types of Moisture-Resistant Plywood
Marine plywood is the best option for extreme moisture resistance, but there are also exterior-grade plywood options that offer some protection against water damage. Explore more about moisture-resistant plywood in our project ideas section.
When to Use Moisture-Resistant Plywood
Opt for moisture-resistant plywood in areas like bathrooms, kitchens, and outdoor structures. It prevents warping and deterioration over time.
8. Cost Considerations When Buying Plywood
Plywood can vary significantly in price depending on factors like grade, thickness, and type. Understanding your budget and project requirements will help you make an informed purchase.
How to Find Plywood Within Your Budget
Shop around and compare prices from different suppliers. Look for discounts and consider buying in bulk if your project requires a large amount of plywood.
Value vs. Price: What to Look For
Focus on finding a balance between cost and quality. Cheaper plywood may save money upfront but can result in higher long-term costs if it fails or needs to be replaced.
