The smell of fresh wood, the gentle hum of tools, the satisfaction of building something with your own hands – it’s all part of the joy of building a shed. A place to store tools, bikes, gardening supplies, or even a cozy retreat for a quiet afternoon, a shed is a much-loved addition to any backyard. But before you start hammering and sawing, there’s one crucial decision to make: what kind of plywood to use for the floor? Should you go with 5/8 inch or 3/4 inch plywood? The answer, as with many DIY projects, is “it depends,” and understanding why will help you make the best choice for your needs.

Plywood, that versatile and often overlooked building material, is the backbone of countless projects. But when it comes to your shed floor, choosing the right thickness is essential for long-lasting stability and structural integrity. We’ll explore the pros and cons of each option, helping you make an informed decision that will leave you confident and ready to build the perfect shed.
Understanding the Basics: Plywood Thickness and Strength
Plywood, by its very nature, is a strong material. Layers of thin wood veneer are glued together with alternating grain directions, creating a panel that is both durable and resistant to warping and bending. But within the world of plywood, there are different thicknesses, and each has its own unique set of strengths and limitations. 5/8 inch and 3/4 inch plywood are the two most common options for shed floors.
5/8 Inch Plywood: A Balance of Strength and Economy
This is the oft-used option for many projects, and for good reason. It’s a good balance of strength and cost-effectiveness. 5/8 inch plywood offers a solid foundation for your shed, able to handle the weight of tools, equipment, and even moderate foot traffic. It’s also easier to handle and cut, making it a good option for DIY projects.
3/4 Inch Plywood: Extra Strength for Heavier Loads
If you plan to store heavy items in your shed, or if you expect heavy foot traffic, 3/4 inch plywood will give you extra peace of mind. This thicker plywood is stronger and provides a more rigid surface, able to handle significantly more weight without sagging or bending. The extra thickness also makes it more resistant to moisture and potential damage.

Factors to Consider for Your Decision
Now that you understand the basics of thickness and strength, we can delve into the decision-making process. There are a number of factors to take into account when choosing between 5/8 inch and 3/4 inch plywood for your shed floor:
1. Intended Use and Expected Load
The most important factor is the intended use of your shed. Are you building a tool shed to store lightweight items? Or are you planning something more ambitious, like a workshop for woodworking projects? The type and weight of the items you plan to store will help you determine the necessary level of strength and rigidity. For purely storage purposes where heavy items are minimal, 5/8 inch plywood might suffice. For workshops with heavy equipment, 3/4 inch will provide that extra reinforcement.
2. Foundation and Framing
The foundation and framing of your shed also play a role. If you have a well-built foundation with strong framing, 5/8 inch plywood might be adequate. However, if your foundation is less robust, or you are concerned about sagging, 3/4 inch plywood will provide greater support and prevent potential structural issues.
3. Climate and Moisture
Your geographic location and the climate you live in are important factors to consider. If you live in an area with high humidity or frequent rain, the extra thickness of 3/4 inch plywood will provide more protection against moisture damage. It is also a good idea to treat the plywood with water-resistant sealant for additional protection.
4. Budget and DIY Skills
Let’s not forget the practical considerations! 3/4 inch plywood is typically more expensive than 5/8 inch plywood. If you’re on a budget and your shed requirements are not overly demanding, 5/8 inch plywood could be a more economical option. Additionally, 3/4 inch plywood can be a bit more challenging to cut and work with due to its thickness. If you are a beginner DIYer, 5/8 inch plywood might be easier to manage.
Expert Tips for Choosing the Right Plywood
When in doubt, consult a local building supply store professional. They can assess your project and advise you on the best plywood thickness for your specific needs. “Many people overthink the plywood choice,” says seasoned builder David Miller. “For most standard sheds, 5/8 inch will be perfectly fine. Focus on building a solid, level foundation and framing and the plywood choice becomes less crucial.” Always remember to factor in the weight of anything you plan to store, and remember that a well-designed and constructed shed can handle a surprising amount of weight.
For a truly durable and long-lasting shed floor, consider utilizing a double layer of 5/8 inch plywood. This allows you to create a floor that is almost as thick as 3/4 inch, but with a more economical approach. By laying the plywood with staggered joints, you can maximize strength and reduce the risk of weak spots.
