Lowe’s 4×8 Plywood Prices (2026): OSB, CDX & Birch Costs

A 4×8 sheet of plywood at Lowe’s runs $10 to $100+ depending on grade — from 7/16″ OSB sheathing to special-order birch hardwood. Using OSB where a visible cabinet face needs sanded birch (or paying birch prices under a roof) wastes money either way. This guide covers real Lowe’s pricing by type, cost per square foot, and how plywood compares to 2×4 framing lumber.

Prices are Lowe’s.com listings checked August 26, 2026, and vary by store and region. Lowe’s.com blocks automated requests, so we could not re-pull them on October 1, 2026: treat every figure as a dated snapshot and confirm the shelf price in the app or by phone before driving out for a specific sheet. Lowe’s runs competitive with, or slightly below, Home Depot on most structural grades, based on our side-by-side Home Depot plywood price comparison.

4×8 Plywood Cost Per Square Foot at Lowe’s

A 4×8 sheet covers 32 square feet, so dividing the sheet price by 32 gives a true apples-to-apples number for comparing against other sheet goods, siding, or per-board-foot lumber. Here’s how Lowe’s current 4×8 plywood prices break down per square foot:

Type	Sheet Price	Cost Per Sq Ft
7/16″ OSB Sheathing	~$10	$0.31
11/32″ Douglas Fir Sheathing	$25.73	$0.80
15/32″ Sanded Plywood Sheathing	$32.26	$1.01
23/32″ CDX Plywood Sheathing	$46.57	$1.46
15/32″ AC Sanded Subfloor	$76.81	$2.40
1/4″ Sanded Plywood	$50.21	$1.57
1/2″ Birch Sanded (2×4 half-sheet)	$48.82	$6.10

📊 Myth: thicker plywood always costs more per square foot. Reality: 1/4″ sanded plywood runs $1.57/sq ft at Lowe’s — more than 23/32″ CDX sheathing at $1.46/sq ft — because sanding and face-veneer grade drive cost more than raw thickness does. Source: Lowe’s.com live plywood pricing, checked August 26, 2026.

Thicker, sanded, and hardwood-faced sheets cost more per square foot because more veneer layers and higher-grade face stock go into the panel — not because Lowe’s marks up the larger sheets. If a project only needs a partial sheet, ask Lowe’s to make a straight rip cut in-store (see our Lowe’s wood cutting service guide for what they cut and what it costs, or our plywood cut-to-size guide) rather than buying a smaller specialty panel at a higher per-square-foot rate.

Why a “3/4-Inch” Sheet Is Labeled 23/32 at Lowe’s

Sheathing-grade plywood is sold by nominal thickness but manufactured to a slightly thinner actual thickness, which is why the price table above lists 15/32″ and 23/32″ instead of 1/2″ and 3/4″. Lowe’s own listings use the actual figure: a sheet sold as 3/4-inch plywood appears under a 23/32-inch title. Search for the wrong number and you can miss the sheet you wanted, or compare two prices that are not the same thickness. OSB is the exception: 7/16″ OSB is already its true thickness.

Nominal (what people say)	Actual (what the label says)	Typical use
3/8″	11/32″	Wall sheathing, cabinet backing
1/2″	15/32″	General sheathing, light subfloor
5/8″	19/32″	Roof decking, wall sheathing
3/4″	23/32″	Subfloor, roof decking

What Real Projects Cost at Lowe’s Sheet Prices

Per-square-foot numbers only help once you convert them into whole sheets, because Lowe’s sells whole sheets and the leftover is yours to pay for. Divide the project area by 32, round up, and multiply by the sheet price. The totals below use the August 26, 2026 prices in the tables above, before tax and before any extra for waste or cutting mistakes.

Project	Area	Sheets needed	Material	Sheet cost
8×10 ft shed wall sheathing (no openings)	80 sq ft	3	7/16″ OSB	~$30
12×12 ft subfloor	144 sq ft	5	15/32″ sanded sheathing	$161.30
12×12 ft subfloor	144 sq ft	5	23/32″ CDX	$232.85
Two cabinet carcass sheets	64 sq ft	2	3/4″ birch (special order)	~$140–$200+

The 12×12 floor shows the catch: 144 divided by 32 is 4.5, so you buy 5 sheets and the half-sheet offcut is worth about $23 of 23/32″ CDX (half of $46.57). Plan your layout so that offcut becomes a closet floor or a workbench top instead of scrap, and the effective cost per square foot of the job drops back toward the shelf price.

How Plywood Pricing Compares to 2×4 Framing Lumber at Lowe’s

A standard 2×4×8 SPF stud at Lowe’s runs about $5–$7, making it the cheapest framing material per piece — but it can’t replace sheet goods for coverage. One 4×8 sheet of 7/16″ OSB (~$10) covers 32 square feet in a single piece; matching that same coverage with dimensional lumber would take far more material and labor. For a full breakdown of stud, plate, and pressure-treated lumber pricing at Lowe’s, see our Lowe’s lumber prices guide.

Rule of thumb: reach for dimensional lumber (2×4, 2×6) for framing and structural members that need to span or bear load along their length, and reach for plywood or OSB sheets when the job needs continuous flat coverage — subfloors, sheathing, roof decks, or cabinet boxes. Mixing the two up, like skipping sheathing in favor of solid lumber over a large span, wastes money without adding strength where it’s actually needed.

Types Of Plywood Available

Softwood Vs. Hardwood Plywood

Softwood plywood, typically made from pine, fir, or spruce, is known for its affordability and versatility — it’s also sold as sanded plywood for interior projects like cabinets, furniture, and shelving. Hardwood plywood, constructed from woods like oak, birch, or maple, offers superior strength and durability, making it suitable for demanding, furniture-grade applications.

What Do OSB and CDX Actually Mean?

OSB (oriented strand board) is an engineered wood panel made from compressed wood strands bonded with resin in cross-oriented layers. It isn’t plywood, but it’s sold and used interchangeably for sheathing because it meets the same structural span ratings at a lower price. CDX plywood is a construction-grade plywood graded C-D on its two faces (C being the better side) with an Exterior (X) glue bond — meaning it’s built to survive job-site weather exposure during construction, not permanent water immersion. Neither product is meant to stay looking good; both are sheathing-grade panels meant to be covered.

Specialty Plywood Varieties

Specialty plywood options cater to specific needs, such as marine plywood, which is designed for outdoor and wet-area use due to its exceptional resistance to water damage and rot.

Marine plywood at Lowe’s: true marine-grade plywood (BS 1088) is a specialty panel that big-box stores often do not keep on the shelf, so ask your store whether it can be ordered and get a quote before planning a build around it. It costs well above standard CDX or sanded plywood. If a project is going in a boat, a shower pan, or anywhere with sustained water contact, marine plywood’s void-free core is worth the premium over pressure-treated CDX, which is only weather-resistant, not rated for constant immersion.

Building material costs across the board have been climbing: the NAHB reports building material prices rose at their fastest pace in three years as of April 2026, with softwood lumber tariffs a major driver — part of why 2026 plywood prices at Lowe’s run higher than in 2024–2025.

For outdoor projects generally, see our guide on pressure treated wood at Lowe’s.

Sustainability And Certifications

Opting for plywood sourced from sustainable forests helps reduce environmental impact — look for certifications like FSC (Forest Stewardship Council) or SFI (Sustainable Forestry Initiative). For structural applications, look for the APA (The Engineered Wood Association) stamp, which confirms the panel meets industry span-rating standards for the grade printed on it.

Frequently Asked Questions

How Expensive Is A Piece Of Plywood?

Plywood and OSB prices at Lowe’s range from about $10 for a 7/16-inch OSB sheathing sheet up to $70–$100+ for a full sheet of birch or hardwood-faced plywood, which is often a special-order item. Thickness, sanding, and face-veneer grade all affect the price more than sheet size alone.

What Is The Cheapest Type Of Plywood?

OSB and softwood sanded plywood are usually the cheapest sheet goods at Lowe’s. OSB is made from compressed wood strands rather than veneer layers, while softwood sanded plywood is made from pine, fir, or spruce — both are common for general construction and DIY projects.

How Much Does A 4×8 Sheet Of 1/2 Inch Plywood Weigh?

A 4×8 sheet of 1/2 inch plywood typically weighs around 48-60 pounds. The weight can vary depending on the type of wood, adhesive used, and any additional treatments applied.

What Plywood Is Best For Outdoor Use?

Marine plywood is best for sustained water exposure due to its void-free core and waterproof glue. For general outdoor framing and sheathing that just needs weather resistance rather than full water immersion, pressure-treated CDX is the more common and far cheaper choice.

How Much Is Plywood Per Square Foot?

4×8 plywood and OSB at Lowe’s runs from about $0.31 per square foot for basic 7/16-inch OSB sheathing up to roughly $2.40 per square foot for 15/32-inch AC sanded subfloor panels. Divide any sheet price by 32 (the square footage of a 4×8 sheet) to compare it against other sheet goods or per-board-foot lumber pricing.

What Is The Standard Size Of A 4×8 Sheet Of Plywood?

A standard 4×8 sheet of plywood measures 4 feet wide by 8 feet long (48 x 96 inches). Actual dimensions are typically slightly smaller due to sanding during manufacturing. Thickness ranges from 1/4 inch to 3/4 inch. For full dimension details, see our guide on standard plywood sheet dimensions.

Is 23/32 Plywood The Same As 3/4 Inch Plywood?

Yes. Sheathing plywood sold as 3/4 inch is manufactured to an actual thickness of 23/32 inch, and Lowe’s lists it under the 23/32 figure. The same pattern applies to 1/2 inch (15/32 actual) and 5/8 inch (19/32 actual).

How Many Sheets Of Plywood Do I Need For A 12 Foot By 12 Foot Floor?

You need 5 sheets. A 12 by 12 foot floor is 144 square feet, a 4×8 sheet covers 32 square feet, and 144 divided by 32 is 4.5, so you round up and end with a half-sheet offcut.

Conclusion

4×8 plywood and OSB prices at Lowe’s span from about $10 for basic OSB sheathing to $70–$100+ for special-order birch and hardwood-faced sheets — thickness alone doesn’t set the price, grade and sanding do.

Match the panel to the job — sheathing-grade for framing that gets covered, sanded or hardwood-faced for anything that stays visible — and check Lowe’s website or call ahead, since pricing varies by store and shifts with lumber-market conditions.
