Plywood Advantages and Disadvantages: Pros, Cons & Best Uses

Plywood is one of the most widely used sheet materials in construction, furniture making and DIY projects. It’s strong, affordable and incredibly versatile, which is why you’ll find it everywhere from house floors and roofs to bespoke cabinets and garden rooms. But like any building material, it isn’t always the right choice.

Understanding the advantages and disadvantages of plywood can help you decide whether it’s suitable for your project. While it offers excellent strength, stability and value for money, factors such as moisture resistance, edge durability and the quality of different plywood grades all need to be considered before buying.

Having used plywood in everything from furniture and workshop storage to garden buildings, I’ve found it’s one of the best all-round sheet materials available when you choose the correct grade for the job. In this guide, I’ll explain the pros and cons of plywood, where it performs best, where it falls short, and how it compares with alternatives such as MDF and OSB.

What is Plywood?

Plywood is a prefabricated wood material, comprising sheets of wood (or “plies” – as in plies of paper sheet, which give the finished product its name) stacked and glued to one another to form a rigid board. The plies are arranged cross-grain in order to improve the structural integrity of the material.

Ply is used in a wide variety of ways, in a wide variety of industries. It is abundant and inexpensive, making it a popular choice for tight budgets, but it also has its merits as a material both qualitatively and aesthetically. Here, though, we will examine in more detail the pros and cons of incorporating ply in a construction context.

7 Advantages of Plywood

1. Excellent Strength-to-Weight Ratio

One of plywood’s biggest advantages is its impressive strength for its weight. Because each veneer layer is laid with the grain running at right angles to the next, the finished board is significantly stronger and more stable than many other sheet materials.

I’ve used structural plywood extensively when building timber-framed garden rooms and workshop floors. An 18mm structural plywood floor feels incredibly solid underfoot while remaining much easier to handle than equivalent solid timber boards.

2. Resists Warping Better Than Solid Timber

Unlike solid wood, which naturally expands and contracts across the grain as humidity changes, plywood remains much more dimensionally stable.

I’ve found this particularly useful when building fitted storage and workshop cabinets. Large plywood panels stay flatter over time, making it much easier to achieve tight-fitting doors and drawers without worrying about seasonal movement.

3. Available in Structural Grades

Not all plywood is decorative. Structural grades are specifically manufactured for load-bearing applications and are commonly used for flooring, roofing, wall sheathing and timber framing.

For my own garden room builds, I regularly specify structural plywood for flooring because it provides a rigid surface that distributes loads evenly while remaining easy to install.

4. Large Sheet Sizes Reduce Joints

Plywood is commonly available in 2440 x 1220mm sheets, allowing large areas to be covered quickly with fewer joints than individual timber boards.

When constructing walls or roof decking, fewer joints not only speed up installation but also create a stronger finished structure.

5. Cost-Effective

Compared with solid hardwood, plywood offers excellent value for money. It provides much of the strength and appearance of timber without the same material cost.

For larger DIY projects such as workshop furniture, storage units or garden buildings, I’ve often chosen birch plywood over solid timber because it delivers a premium result while keeping the overall project budget under control.

6. Makes Efficient Use of Timber

Because plywood is manufactured from thin veneers rather than large solid boards, more of each tree can be used during production.

Many modern plywood products are also available with FSC® or PEFC certification, giving buyers confidence that the timber has come from responsibly managed forests.

7. Attractive Natural Finish

High-quality hardwood plywood, particularly birch plywood, has an attractive, consistent grain that often looks great with nothing more than a clear finish.

Many of the workshop cabinets and storage solutions I’ve built are simply coated with Osmo Polyx Oil, allowing the natural timber grain to remain visible while providing a durable, easy-to-clean surface.

7 Disadvantages of Plywood

1. Poor Quality Plywood Can Delaminate

Not all plywood is manufactured to the same standard. Lower-quality boards may contain internal voids or use inferior adhesives, increasing the risk of layers separating over time.

I’ve learned that spending slightly more on reputable structural or birch plywood usually saves money in the long run through improved strength, flatter sheets and fewer defects.

2. Exposed Edges Need Finishing

Unlike solid timber, the exposed layers of plywood are clearly visible along the edges. Depending on the project, this may or may not be desirable.

For painted furniture, I usually fill and sand the edges before applying primer. On birch plywood furniture, however, I often leave the layered edge exposed as it has become a popular design feature in modern interiors.

3. Not All Plywood Is Waterproof

This is one of the biggest misconceptions about plywood.

While exterior and marine plywood are manufactured with waterproof adhesives, standard interior plywood should never be used where it will be exposed to prolonged moisture.

When building outdoor projects, I always choose exterior-grade or marine plywood where there’s any risk of damp conditions. Using standard interior plywood outdoors almost always leads to swelling and premature failure.

4. Plywood Dust Can Be Hazardous

Cutting or sanding plywood produces fine dust that may contain adhesives, resins and volatile organic compounds (VOCs).

Whenever I’m machining plywood, I wear a suitable dust mask or respirator, use dust extraction wherever possible and work in a well-ventilated area. These simple precautions make a huge difference, especially during larger projects.

5. Heavier Than Some Alternative Boards

Although plywood is lighter than many solid timber products, it can still be surprisingly heavy.

An 18mm hardwood plywood sheet weighs around 30kg, making it awkward for one person to lift safely. Whenever possible, I break large sheets down with a track saw before moving them around the workshop.

6. Surface Quality Can Vary

The appearance of plywood depends heavily on its grade.

Lower grades may contain knots, repairs and patches that are perfectly acceptable for structural work but unsuitable for visible furniture projects. If appearance matters, I generally buy birch plywood or furniture-grade hardwood plywood to avoid unnecessary filling and sanding.

7. Premium Grades Can Be Expensive

Although plywood is generally affordable, specialist products such as birch plywood and marine plywood can be significantly more expensive than standard softwood sheets.

That said, I’ve found it’s usually worth paying for the correct grade from the outset. Better-quality plywood machines more cleanly, stays flatter and often results in a much better finished project with less wasted material.

Plywood vs MDF vs OSB vs Chipboard

Choosing the right sheet material can make a huge difference to the strength, durability and finish of your project. While plywood is often my first choice, each material has its strengths depending on what you’re building.

Material	Best For	Main Advantages	Main Drawbacks
Plywood	Floors, cabinets, furniture, structural projects	Strong, stable, moisture-resistant (correct grade), holds screws well	More expensive than MDF or chipboard
MDF	Painted furniture, shelving, interior mouldings	Smooth surface, easy to paint, inexpensive	Heavy, poor moisture resistance, weaker screw holding
OSB	Roofs, walls, subfloors, sheds	Very strong, affordable, excellent structural board	Rough appearance, unsuitable for fine furniture
Chipboard (Particle Board)	Budget furniture, worktops (laminated), shelving	Very inexpensive and lightweight	Weak edges, poor moisture resistance, limited durability

Plywood vs MDF

If I’m building painted furniture or fitted wardrobes, MDF is often the better choice because its perfectly smooth surface produces an excellent painted finish with very little preparation.

However, for cabinets, workshop furniture and shelving that need to withstand heavy use, I almost always choose plywood. It holds screws much better than MDF and is far less likely to sag over time. I also prefer the natural timber appearance of birch plywood, which looks fantastic with a clear finish.

Plywood vs OSB

OSB and plywood are both structural sheet materials, but I tend to use them for different jobs.

When constructing garden rooms, I often use OSB for hidden structural applications such as wall sheathing because it’s cost-effective and exceptionally strong.

For visible surfaces such as flooring, cabinetry or furniture, plywood is the clear winner. It machines more cleanly, produces a much nicer finish and is available in decorative hardwood veneers that require very little finishing.

Plywood vs Chipboard

Chipboard has its place, particularly in low-cost furniture and laminate worktops, but it’s not something I’d recommend for projects that need long-term durability.

Once chipboard gets wet it tends to swell quickly and permanently lose its strength. I’ve repaired plenty of damaged chipboard furniture over the years, whereas plywood generally survives knocks, moisture and repeated fixing much better.

Which Material Do I Recommend?

After using all four materials across various DIY and construction projects, plywood is still my preferred all-round sheet material.

For my own workshop cabinets, storage units and many of my garden room builds, I usually choose structural or birch plywood because it offers an excellent balance of strength, durability, appearance and ease of working.

That doesn’t mean it’s always the best option. If I’m building a piece of furniture that’s going to be painted, MDF can save both time and money. For hidden structural walls or roof decking, OSB is often the most economical choice. The right material ultimately depends on the project, but if I could only keep one sheet material in my workshop, it would almost certainly be plywood.

Using Plywood in Furniture

Plywood is a popular material for furniture making due to its stability, durability, and affordability. Unlike solid wood, which can be prone to warping and cracking, plywood is less susceptible to these issues, making it a more reliable choice for furniture construction. In addition, its uniform surface makes it easier to work with, as it requires less sanding and smoothing compared to solid wood.

Plywood also offers designers a wide range of possibilities, as it can be stained, painted, or finished in a variety of ways to match the desired aesthetic. It can also be bent or shaped into curves, making it a versatile option for creating modern, flowing furniture designs. Hardwood plywoods, in particular, have a beautiful grain that can be showcased through a clear or semi-transparent finish, adding a touch of warmth and texture to furniture pieces.

One of the most significant benefits of using plywood in furniture is that it is a more sustainable option compared to solid wood. Ply is made from thin layers of wood, which are glued together in a cross-grain orientation, making it possible to use smaller pieces of wood that might otherwise be considered waste. This makes it a more eco-friendly choice, as it reduces the need for large pieces of solid wood, which are often harvested from old-growth forests.

Ply is a versatile and practical material for furniture making, offering designers and manufacturers a range of benefits, including stability, durability, affordability, and versatility. Whether you’re creating contemporary or traditional pieces, ply provides a sustainable and practical option that can bring a touch of warmth and texture to any furniture design.

Plywood in art and sculpture

Plywood is not just a material for construction and furniture making. It is also a versatile and practical medium for artists and sculptors. Due to its affordability, light weight, and stability, plywood is an ideal choice for creating large-scale sculptures, wall hangings, and other works of art.

One of the most significant benefits of using this manufactured wood in art is that it is relatively easy to work with. Unlike solid wood, which can be difficult to carve and shape, plywood can be cut, sanded, and drilled with relative ease, making it a versatile option for artists looking to experiment with different forms and textures.

This type of wood is also a great choice for artists who work with a variety of mediums. It can be painted, stained, or finished in a variety of ways, allowing artists to create multi-layered works that incorporate a range of textures and finishes. This versatility makes it possible for artists to create works that are both aesthetically pleasing and functional.

In addition, plywood is a sustainable option for artists who are concerned about the environment. As a material made from thin layers of wood, it enables artists to use smaller pieces of wood that might otherwise be considered waste, reducing the need for large pieces of solid wood, which are often harvested from old-growth forests.

Conclusion

Plywood is a versatile and cost-effective material that has found its way into many construction and design projects worldwide. Its benefits include its low cost, large surface area, and variety of shapes and sizes. However, it also has its limitations, such as its lack of suitability for outdoor use, difficulties in sawing and treating, and health hazards associated with inhaling its dust. Ultimately, the choice to use plywood will depend on the specific requirements of the project and the constraints of the budget and materials. However, it is clear that plywood has a place in the world of construction and design, as a low-cost solution that can bring many benefits to a project.
