4×8 Plywood Panels: Grades, Types, and Best Uses by Project
A 4×8 plywood panel measures 47-7/8” × 95-7/8” actual size — slightly under the nominal 48”×96” due to manufacturing tolerances. The grade determines the application: CDX and BCX panels suit structural sheathing and subfloor work, while birch and maple panels handle cabinetry and furniture. Choosing the wrong grade means either overpaying for hidden structural work or using an under-spec panel where strength matters.
Quick Answer
For structural framing and sheathing: CDX plywood ($25–30/sheet). For sanded, paintable surfaces: BCX or AC plywood ($35–45). For cabinets and furniture: 3/4” birch ($55–80). For marine or outdoor use: MDO or marine-grade plywood ($80+). Always match the grade to the exposure condition.
Introduction To Plywood Panels 4×8
Plywood panels measuring 4×8 feet are popular in construction. They are made from thin layers of wood veneer. These layers are glued together. This makes plywood strong and versatile.
Many people use 4×8 plywood panels for various projects. They are easy to handle and fit well in tight spaces. The size is standard, making it convenient for builders and DIY enthusiasts.
Popular Uses In Construction And DIY Projects
Plywood panels serve many purposes. Here are some popular uses:

4×8 Plywood Grades and Types: Which to Use
Plywood grades use a two-letter system — one letter for the face veneer and one for the back. Grade A means smooth, sanded, and free of knots. Grade D allows knots and defects. The most common 4×8 panel grades at home improvement stores are CDX, BCX, and A-C (also called AC plywood).
| Grade | Face / Back | Glue Type | Best Use | Approx. Price (3/4”) |
|---|---|---|---|---|
| CDX | C face / D back | Exterior (X) | Roof sheathing, subfloor, wall sheathing | $25–30 |
| BCX | B face / C back | Exterior (X) | Soffits, siding, painted exterior | $35–45 |
| AC / A-C | A face / C back | Interior | Cabinets, shelves, visible interior surfaces | $45–55 |
| Birch (BB) | Sanded birch | Interior | Cabinets, furniture, drawer boxes | $55–80 |
| Marine | A / A | Waterproof | Boat building, outdoor furniture, wet areas | $80–120 |
For garage shelves: use 3/4” CDX or BCX — CDX is cheaper and strong enough for shelving loads. A 3/4” plywood shelf spanning 24 inches without support holds approximately 200 lbs per square foot. For a cleaner finish, step up to BCX and sand the face. See our 3/4 inch plywood load capacity guide for exact span calculations.
For cabinets and furniture: birch plywood has a smooth, void-free face that machines cleanly and accepts paint or clear finish without telegraphing grain lines. Baltic birch uses an all-birch core (no filler layers), making it stronger at exposed edges and ideal for drawer construction.

Frequently Asked Questions
What Are Plywood Panels 4×8 Used For?
4×8 plywood panels cover the full range of construction and woodworking applications: roof sheathing, subfloor, wall sheathing (CDX grade), cabinets and built-ins (birch or AC grade), furniture and shelving (birch), and outdoor structures (exterior or marine grade). The 4×8 size is the industry standard because it aligns with 16-inch and 24-inch on-center framing without waste.
How Thick Are 4×8 Plywood Panels?
4×8 plywood comes in thicknesses from 1/8” to 1”. The most common are: 1/4” (lightweight wall panels, drawer bottoms), 3/8” (underlayment), 1/2” (cabinets, lighter shelving), 5/8” (subfloor on 19.2” joist spacing), and 3/4” (structural shelving, cabinets, furniture). Note: actual thicknesses are slightly under nominal — 3/4” is typically 23/32”.
Are 4×8 Plywood Panels Water-Resistant?
It depends on the grade. CDX and BCX use exterior-rated glue that resists moisture exposure during construction but is not fully waterproof for long-term outdoor use. Marine-grade plywood uses waterproof phenolic glue and void-free veneers throughout — it handles sustained water exposure. For covered outdoor projects, ACX or BCX with a paint/sealant coat is sufficient. For constant wet contact, use marine grade only.
What Types Of Wood Are Used In Plywood Panels?
Douglas fir is the most common species in structural CDX plywood sold in North America — it has excellent strength-to-weight ratio for framing applications. Birch is used in cabinet-grade panels for its smooth, tight-grained face. Maple gives a uniform, paint-friendly surface. Baltic birch (all-birch core from Eastern Europe) is preferred for shop furniture and drawer construction because it has no interior voids.
What Is the Actual Size of a 4×8 Plywood Sheet?
The actual size of a 4×8 plywood sheet is 47-7/8” × 95-7/8” — slightly under the nominal 48” × 96”. This 1/8” tolerance is standard across manufacturers and accounts for saw kerf and edge finishing. When calculating material needs for an exact fit, always measure actual dimensions rather than assuming the nominal 4′ × 8′ size.
What Is the Difference Between CDX and BCX Plywood?
CDX has a C-grade face (knot holes up to 1-1/2” allowed) and a D-grade back (larger defects allowed). BCX has a B-grade face (only small patches allowed, no open knot holes) and a C-grade back. Both use exterior (X) glue. Use CDX for hidden structural applications — subfloor, sheathing. Use BCX when the surface will be painted or left partially visible, such as soffits or garage ceilings.
