Plywood is often sold in 1/4“, 1/2“, or 3/4” nominal thicknesses, but the actual thickness is often 1/32” thinner. Because the actual thickness may vary measuring the plywood is the only accurate way to determine its thickness. A 3/4” sheet is actually 23/32” thick. A 1/2” sheet is actually 15/32” thick.

What is the strongest 3/4 plywood?
The answer is marine plywood. It is the strongest and toughest of all plywood on the market. High-quality glues hold the plies in marine plywood together. That makes them structurally sound and resistant to moisture.
Is OSB stronger than plywood?
OSB and plywood offer similar (and sufficient) performance in terms of strength and functionality, though plywood is about 7% stronger. Plywood will absorb moisture quicker than OSB, but consequently it will also dry quicker.
What size is a sheet of 3/4 plywood?
x 2 ft. x 4 ft.; Actual: 0.734 in. x 23.75 in. x 47.75 in.).
Can you buy plywood bigger than 4×8?
Widths and Lengths As described, the most common size for a sheet of plywood is 4 x 8 feet. Hardwood plywood is also available in sizes 2 x 2 feet, 2 x 4 feet, and 4 x 4 feet. Utility plywood is available in sheets that are longer, measuring 4 x 10 feet.
What are the four grades of plywood?

What size plywood is best for subfloor?
The minimum thickness of plywood for subflooring is about 5/8 inch. Since it does not hold fasteners as well as plywood, OSB must be a little thicker, or at least 23/32 inch. There are several factors that determine what subfloor thickness is optimal for added benefits like insulation.
How much does a 4 by 8 sheet of plywood cost?
“A sheet of [4-foot by 8-foot] half-inch plywood costs $65 today.
What does OSB board stand for?
Oriented Strand Board (OSB) that is conditioned for structural applications in humid environments. In comparison to Medium Density Fibreboard (MDF), Chipboard and other plywood alternatives, OSB sacrifices a smooth surface for enhanced mechanical performance by using longer strands of wood.
How much load can 3/4 plywood support?
A 12-by-36-inch piece of 3/4-inch fir plywood can easily support 50 pounds. However, a 12-by-36-inch piece of 1/4-inch thick plywood will not support that much weight. It will only support about 5 pounds before bending.
Which type of plywood is best?
Aircraft plywood is the most durable type available. It uses hardwoods to create strong boards that can resist heat and moisture. Aircraft plywood is made of very thin veneers, which keep it light and flexible while providing significant strength.
What is marine grade plywood?
Marine Grade Plywood is an exterior structural panel, sanded on both sides, most commonly made from Douglas fir or Pine. Other species of hardwood may also be used for marine plywood, usually in the Marine (boating) industry.
Do screws hold better in OSB or plywood?
Group 1 plywood, made from the strongest species of wood such as Southern Yellow Pine, holds screws better than OSB.
Why is plywood cheaper than OSB?
Plywood is the more expensive option to build with than OSB. The material tends to be thicker and needs to be made to more exacting standards, which increases costs. A 4×8-foot sheet of construction-grade plywood costs roughly $10 a sheet, while the same size sheet of OSB costs only $6 a sheet.
Which is cheaper plywood or OSB?
OSB is less expensive than plywood. To build a typical 2,400-square foot home, OSB may cost $700 less than plywood. OSB is considered by many to be a “green” building material because it can be made from smaller-diameter trees, such as poplars, that are often farmed.
What is the cheapest plywood to buy?
D-grade plywood: The cheapest type of plywood veneers, these sheets typically haven’t been repaired. The flaws can be slightly larger and the knots in this type of plywood can be up to 2.5 inches in diameter. CDX: CDX-grade plywood is typically inexpensive material, as it is made of the two lowest grades (C and D).
Is plywood stronger than regular wood?
Strength and Stiffness Solid wood is significantly stronger than plywood, especially in terms of stiffness. A shelf made from solid wood will sag less than one made from plywood of the same dimensions.
Why is plywood expensive?
Wood products prices typically fluctuate more than most goods, because homebuilding can move up or down much faster than sawmill capacity can. Lumber and plywood prices are so high now because of the short-run dynamics of demand and supply.
