How much weight can a 1/2 plywood hold?
As you can see, a 1/2″ plywood can support up to 35 pounds per square foot. But doubling that thickness to 1″ of plywood supports up to 164 pounds per square food. The increased thickness means plywood supports much more weight as it can redistribute the stress away from the center.

Plywood and OSB Weight Factors
The weight of plywood and OSB depends partly on the amount and the type of the adhesives, primers, and sealants used to make it. Different types of plywood will use different amounts of these substances, and they are very heavy relative to wood.
What is Plywood Made of?
Plywood is composed of approximately 92% – 97% wood, with the remainder made up by primers, sealants, and adhesives such as phenol formaldehyde resin.
Weights of Different Types of Plywood
APA Plywood Standard: The Engineered Wood Association (formerly the American Plywood Association) provides standard notional plywood weights for use in determining expected dead loads when performing structural engineering calculations.
Ask the Lumber Company!
The values given in the following tables are meant to provide a general idea of typical engineered wood panel weights, and should not be used if precise values are needed for critical engineering calculations.
About Our Plywood Weight Charts
The following tables provide typical weights (dead load, self-weight) for plywood, OSB, and other engineered wood panels.
Why Is It Important to Know the Weight of Plywood?
Plywood is used for roof sheathing as well as subfloors. Both of these structures are supported by structural framing and that framing has limits on how much weight it can hold. Applying too much weight to framing can cause serious structural problems.
What Factors Impact Plywood Weight?
There are a surprising number of factors that impact plywood weight ranging from the obvious, thickness and size, to the not so obvious, wood species and density. Understanding how these factors impact the overall weight of a sheet of plywood is crucial to calculate its weight.
How Much Does a Sheet of Plywood Weight
Understanding how much the most commonly-used sizes of standard plywood weighs is helpful when determining the overall weight of a floor or roof or planning logistics for transporting the wood from store to site.
Weight of Pressure Treated Plywood
As discussed in detail above, the liquid chemicals used to protect this type of plywood from the elements significantly increase weight. Of course, treated plywood, like all treated lumber, dries over time and becomes lighter.
How Much Does Baltic Birch Plywood Weigh?
This high-quality type of plywood, produced in Russia, is renowned for its strength. Baltic plywood is made of all plywood with no fillers, making it very strong even at thinner thicknesses. This makes it suitable for durable furniture and even skateboards. Because it is denser than other types of plywood, it weighs more.
How Much Does Marine Grade Plywood Weigh?
While marine plywood is not waterproof, it does use higher quality outer plies that protect the wood from the elements. The glue used to make standard plywood is prone to coming apart in humid coastal environments. Marine-grade plywood uses a higher quality glue that better resists moisture.
Weight of Plywood per Square Foot
If a little math doesn’t intimidate you, then calculating plywood weight yourself isn’t that difficult once you know what values to use. To determine the total weight, you need to know the weight per square foot of the plywood.
Is Plywood Ideal for Weight-Bearing Applications?
If you are wondering whether or not plywood is ideal for weight-bearing applications, what you need to know here is that it really does depend on the size, the thickness, and the type of plywood in question. There are many different types of plywood out there, dozens in fact, and they all have different strengths.
What Determines How Strong Plywood is?
Above, we did mention that the number one determining factor in terms of how much weight a piece of plywood can bear is how thick it is, but with that being said, thickness is not the only determining factor here.
How to Calculate How Much Weight Your Plywood Can Support
Quite honestly, if you are not a mathematical genius and you are not familiar with all of the technical terms related to plywood and engineering, then you are best off using a plywood load calculator found online.

Without a shadow of a doubt, the strongest type of plywood out there is marine plywood. Marine plywood can easily hold several 100 pounds per sheet.
Summary
Now that you know exactly how to calculate the load-bearing capacity of the specific piece of plywood as well as the various factors that affect how much weight plywood can bear, you can now choose the right kind of plywood for your specific application.
How Much Does Pressure-Treated Lumber Weigh?
The weight of pressure-treated lumber depends on how much time has gone by since the wood was treated, as well as the size of the board or post.
Type of Wood Used for Pressure-Treating
Around 85% of the pressure-treated wood in the US is made from southern yellow pine.
Wood Pressure-Treatment Process
Pressure-treated lumber is produced by using high pressure to force a solution of water and chemical preservatives deep into the wood.
Weight of Water in Pressure-Treated Lumber
The noticeable extra weight of pressure-treated lumber is due to the water added during the treatment process.
Weight of Preservative in Pressure-Treated Lumber
Once it dries, the weight difference between pressure-treated lumber and untreated lumber is entirely due to the weight of the preservative retained in the wood. This weight is minimal.
About this Pressure-Treated Lumber Weight Table
The following table provides the heaviest approximate weight (dead load, self-weight) per linear foot of pressure-treated lumber.
Ask the Lumber Company!
The values given in the table are meant to provide a general idea of typical pressure-treated lumber weights, and should not be used if precise values are needed for critical engineering calculations.
