What is better for shed floor OSB or plywood?

When it comes to building a shed, one of the most important decisions you will have to make is what type of material to use for the floor. The two most common options are oriented strand board (OSB) and plywood. Both materials have their own advantages and disadvantages, and it can be difficult to determine which one is better for your shed. In this article, we will discuss the differences between OSB and plywood and help you decide which one is the best choice for your shed floor.

What is OSB?

Oriented strand board, commonly known as OSB, is a type of engineered wood product that is made by compressing and gluing together strands of wood in a specific orientation. It is similar to plywood in terms of its composition, but instead of using thin layers of wood veneer, OSB uses strands of wood that are arranged in a specific pattern. This results in a strong and durable panel that is suitable for a variety of applications, including shed floors.

What is plywood?

Plywood is also an engineered wood product, but it is made by gluing together thin layers of wood veneer at right angles to each other. This cross-grain construction gives plywood its strength and stability. It is a popular choice for shed floors due to its affordability and versatility.


When it comes to durability, both OSB and plywood are strong and long-lasting materials. However, OSB tends to be more susceptible to moisture damage than plywood. If exposed to water, OSB can swell and become weak, which can compromise the structural integrity of your shed floor. On the other hand, plywood is more resistant to moisture and can withstand exposure to water for longer periods without significant damage.


Both OSB and plywood are strong materials, but plywood has a slight edge in terms of strength. The cross-grain construction of plywood makes it more resistant to bending and twisting, making it a better choice for heavy-duty applications. However, OSB is still a strong and durable material that can support the weight of most shed contents.


When it comes to cost, OSB is generally more affordable than plywood. This is because OSB is made from smaller strands of wood, which are cheaper to produce than the larger sheets of veneer used in plywood. If you are on a tight budget, OSB may be the better option for your shed floor.


In terms of appearance, plywood has a more traditional and natural look compared to OSB. OSB has a rough and textured surface, while plywood has a smooth and uniform appearance. If you plan on using your shed for more than just storage, you may want to consider the aesthetic appeal of your shed floor.

Ease of installation

Both OSB and plywood are relatively easy to install, but OSB has a slight advantage in this area. OSB panels are larger and lighter than plywood, making them easier to handle and install. However, plywood can be cut and shaped more easily, which can be beneficial if you have an irregularly shaped shed floor.


In conclusion, both OSB and plywood are suitable materials for shed floors, and the choice ultimately depends on your specific needs and preferences. If you are on a tight budget, OSB may be the better option, but if you want a stronger and more moisture-resistant floor, plywood may be the way to go. Consider the factors discussed in this article and choose the material that best fits your needs and budget.
