Structural strength, durability, moisture resistance, cabinet and furniture performance, cost comparison, and a complete decision matrix every panel material compared head-to-head.

QUICK ANSWER: WHICH PANEL SHOULD YOU USE?

Construction sheathing and subfloor: OSB or CDX plywood OSB costs 15 - 25% less; plywood edges perform better in moisture. Cabinet boxes: plywood only holds screws, resists moisture, lasts 30+ years. Cabinet door panels (painted): MDF smoothest painted surface, no grain bleed. Furniture (stained, natural wood): plywood. Particle board: avoid for anything structural, anything in kitchens, or any application with moisture risk. Use it only for interior shelf cores and budget furniture where longevity isn’t the priority.

Walk into any home improvement store and you’ll find four panel materials competing for space in the same aisle: plywood, OSB, particle board, and MDF. They all come in 4×8 sheets. They’re all made of wood. And they can all feel similar in your hands at the store. But they perform entirely differently in real applications, and choosing the wrong one is a common and expensive mistake.

This guide cuts through the confusion. It covers every head-to-head comparison structural, moisture, cabinet, furniture, cost, and longevity with honest verdicts and a complete decision matrix so you know exactly which panel to use for every application.

What Each Material Actually Is

Before comparing them, it helps to understand what each material is made from. The manufacturing process drives most of the performance differences.

Plywood

WHAT IT IS: Structural panel made from thin wood veneer sheets (plies) glued together in alternating perpendicular grain directions

HOW IT’S MADE: Logs are rotary-peeled into continuous veneer ribbons, dried to precise moisture content, glued in cross-laminated layers, hot-pressed, then sanded and graded

COMMON GRADES/TYPES: CDX (C/D, Exposure 1), BCX, ACX, Baltic birch B/BB, marine grade, MDO, pressure-treated

BEST FOR: Cabinet boxes, furniture, subfloor, roof and wall sheathing, flooring, anywhere structural performance and moisture resistance matter

AVOID FOR: Applications requiring an ultra-smooth painted surface (MDF is better) or extreme budget-sensitivity where structural performance is secondary

OSB (Oriented Strand Board)

WHAT IT IS: Structural panel made from wood strands 3–4 inches long, compressed in oriented layers with resin binder

HOW IT’S MADE: Logs are debarked and flaked into strands, dried, blended with resin and wax, oriented in layers (face strands parallel to long dimension, core strands perpendicular), then hot-pressed into panels

COMMON GRADES/TYPES: Exposure 1 (standard), Exposure 2, ZIP System (integrated weather barrier), LP SmartSide components

BEST FOR: Roof sheathing, wall sheathing, subfloor, structural applications where CDX plywood would be used but at lower cost

AVOID FOR: Cabinet boxes, finished furniture, anything visible or decorative, applications with sustained edge moisture exposure

Particle Board (Chipboard / Particleboard)

WHAT IT IS: Non-structural panel made from wood chips, sawdust, and wood processing waste compressed with resin binder

HOW IT’S MADE: Wood waste materials are ground to fine particles, blended with urea-formaldehyde or similar resin, mat-formed, then hot-pressed. Density is more uniform than plywood or OSB.

COMMON GRADES/TYPES: Standard particleboard, industrial particleboard, melamine-faced particleboard (most common in budget furniture)

BEST FOR: Budget furniture cores, interior shelf substrates behind laminate, flat-pack furniture (IKEA-style), non-structural interior applications

AVOID FOR: Cabinet boxes, subfloor, roof sheathing, wall sheathing, any application with moisture exposure, any application requiring screw holding in the edge

MDF (Medium Density Fiberboard)

WHAT IT IS: Dense, uniform panel made from very fine wood fibers compressed with resin under heat and pressure

HOW IT’S MADE: Wood is broken down to individual fibers, mixed with resin, mat-formed to uniform density throughout, hot-pressed to final thickness. No grain direction perfectly uniform.

COMMON GRADES/TYPES: Standard MDF, moisture-resistant MDF (MR-MDF), fire-retardant MDF, ultra-light MDF, HDF (High Density Fiberboard)

BEST FOR: Painted cabinet door panels, painted furniture faces, painted wainscoting, routed trim and molding profiles, speaker boxes, any application where a perfectly smooth painted surface is needed

AVOID FOR: Structural cabinet boxes, subfloor, roof sheathing, any application with moisture (even kitchen steam), any application requiring edge screws

Plywood vs OSB: Structural Strength

This is the most practically important comparison for anyone doing construction choosing between plywood and OSB for sheathing, subfloor, or any structural panel application. Both are APA-rated structural panels. Both serve the same applications at equivalent span ratings. The real performance differences show up in specific conditions.

WHERE THEY PERFORM THE SAME

For standard structural applications roof sheathing at 16-inch rafter spacing with 1/2 inch panels, subfloor at 16-inch joist spacing with 3/4 inch panels, wall sheathing OSB and plywood meet identical APA performance standards. An OSB panel with a 32/16 span rating and a CDX plywood panel with the same rating will perform identically under structural load in controlled conditions. Building codes in virtually all US jurisdictions accept either material for the same structural applications.

WHERE PLYWOOD HAS GENUINE ADVANTAGES

OSB by 15–25%

THE OSB EDGE SWELL PROBLEM EXPLAINED

When OSB panel edges absorb moisture rain during construction, or a leak later — the wood strands swell and the panel edge puffs up. Unlike plywood, OSB edges don’t fully recover to their original dimension when they dry. On a roof deck, this permanent swelling at panel joints creates ridges that telegraph through finished asphalt shingles as visible ‘picture framing.’ On a subfloor, edge swell causes floor squeaking at panel joints. CDX plywood edges swell less and recover better because the continuous grain structure of the cross-plied veneers restrains swelling more effectively than the compressed strand structure of OSB.

WHEN TO CHOOSE OSB VS PLYWOOD FOR STRUCTURAL APPLICATIONS

Budget new construction, dry climates, tight construction schedule — Choose OSB

If cost is the priority, the construction schedule is fast (deck covered before significant rain), and the climate is not coastal or persistently wet, OSB saves 15–25% on structural panels with no meaningful performance penalty in normal conditions.

Premium builds, re-roofing, coastal or high-humidity climates — Choose CDX Plywood

When the deck will be exposed to weather for more than a day or two during construction, when the highest-rated roofing wind warranties are required, or in coastal and high-humidity environments, CDX plywood’s better edge performance justifies the cost premium.

High-wind and seismic zones with engineered shear walls — Choose CDX Plywood (engineer-specified)

Engineered shear wall systems frequently specify plywood for higher allowable shear values. Never substitute OSB for plywood in an engineered shear wall specification without written approval from the engineer of record.

Plywood vs Particle Board: Durability

This is the comparison that matters most for cabinets and furniture. The difference between plywood and particle board in these applications isn’t a matter of degree it’s a fundamental difference in long-term performance.

HOW THEY’RE DIFFERENT AT A STRUCTURAL LEVEL

Plywood is made from continuous wood fiber oriented in cross-laminated grain directions. The fiber is intact the same cellulose and lignin structure that gives solid wood its strength. Particle board is made from ground wood particles with no continuous fiber orientation. The resin binder holds the particles together, but there is no underlying grain structure to resist splitting, hold fasteners, or resist moisture swelling.

This fundamental difference drives every performance outcome in the comparison.

THE MOISTURE FAILURE MODE

Particle board’s relationship with moisture is irreversible. When particle board absorbs water — from a plumbing leak under a kitchen sink, from kitchen steam and condensation over years, from a bathroom humidity cycle — the ground wood particles swell and the resin binder loses its grip. The panel expands, becomes soft and crumbly, and does not return to its original dimensions when it dries. The damage is permanent.

Plywood in the same conditions shows some moisture effects — face veneer may check slightly, the panel may swell marginally — but the continuous fiber structure and cross-ply construction resist the catastrophic failure mode that ends particle board cabinets prematurely.

WHY BUDGET CABINET LINES USE PARTICLE BOARD

The answer is simple: particle board costs 50–70% less than birch or maple plywood per sheet. A kitchen’s worth of cabinet boxes represents $800–1,500 in materials with plywood, vs $400–$700 with particle board. Budget manufacturers and big-box cabinet lines use particle board to hit price points. The trade-off is a cabinet that performs well for 10–12 years then starts showing hinge problems, shelf sag, and moisture damage around year 10–15. Plywood cabinets absorb the higher upfront cost and deliver 25–40 years of reliable performance.

Plywood vs MDF: Cabinets & Furniture

This is the nuanced comparison — because unlike the plywood-vs-particle-board comparison where plywood wins almost everywhere, the plywood-vs-MDF comparison has real split verdicts depending on the application.

THE PROFESSIONAL RULE FOR CABINETS AND FURNITURE

Professional cabinet shops use both materials, but for different components. This is not a compromise — it’s the correct specification for each:

THE MDF KITCHEN CABINET PROBLEM THAT SHOWS UP AT YEAR 5

Some kitchen cabinet lines use MDF for both box construction AND door panels as a cost measure. The door panels look fine painted — that’s MDF doing what it does well. But the hinge screws are in MDF box sides, and MDF edge screw holding degrades faster than particle board. By year 5–8, doors start sagging as hinge screws loosen in the MDF edges. By year 10, adjustment is no longer possible because the holes have stripped. The lesson: use MDF where it helps (door panels), never where it hurts (structural box components).

THE TRUE COST OF CHEAP CABINETS

Particle board cabinet boxes cost $600–1,500 less than plywood for a standard kitchen. But they typically need full replacement within 15 years, vs plywood that runs 30+ years. Add the labor cost of a kitchen cabinet replacement ($3,000–$8,000+) and the ‘cheap’ particle board option costs significantly more over the kitchen’s life. This is why the value case for plywood box construction is strong even at higher upfront cost.

Which Is Strongest? Structural Strength Ranked

THE ANSWER TO ‘WHICH IS STRONGEST?’

Plywood. In almost every strength category that matters for real applications — bending, tensile, shear, screw holding, impact, moisture-exposed strength — plywood either matches or exceeds the other materials. OSB matches plywood for structural bending and shear in dry conditions. Particle board and MDF are not structural materials and should not be compared to plywood or OSB for any load-bearing application.

THE ONE RULE THAT COVERS 80% OF DECISIONS

If the application is structural, load-bearing, outdoors, in a kitchen or bathroom, or involves screws near an edge: use plywood. If the application is interior, non-structural, painted, and involves flat face surfaces only: MDF is worth considering for the paint quality benefit. If the application is construction sheathing and budget matters: OSB. Particle board is correct only for non-structural interior applications where longevity beyond 10–15 years isn’t required.

OSB vs Sterling Board: Are They the Same?

Sterling Board is a brand name for OSB (Oriented Strand Board) used primarily in the UK and Irish markets — it’s the same engineered wood panel product as OSB sold in North America under the generic name. The manufacturing process, panel structure, and performance characteristics are identical.

The confusion arises because ‘sterling board’ became so common in British construction that many people use it as the generic name the way North Americans use ‘OSB.’ If you’re in a UK or Irish context and someone says ‘sterling board,’ they mean OSB. The structural grades, moisture exposure ratings, and applications are the same. Everything in the OSB sections of this guide applies directly to sterling board.

Frequently Asked Questions

Is plywood stronger than OSB?

At equivalent thickness and span rating, plywood and OSB have comparable structural strength for the bending loads that matter in roof and floor applications. The meaningful advantage plywood has over OSB is at the panel edges: OSB edges swell more when wet and don’t fully recover, which can cause visible ridging under shingles and floor squeaking at subfloor joints. Plywood also has higher published allowable shear values in some engineered applications. For general structural use, both are adequate; for premium applications in wet climates or engineered shear systems, plywood is the better specification.

Is plywood stronger than particle board?

Yes, dramatically. Plywood is a structural panel material; particle board is not. Plywood holds screws reliably in both the face and edge, resists moisture without permanent swelling, handles bending loads without sagging at normal shelf spans, and lasts 25 to 40+ years in kitchen conditions. Particle board holds screws adequately in the face initially but loses holding capacity over time as the compressed particles degrade, fails catastrophically at edges (screws strip easily on first removal), swells permanently when wet, and typically lasts 10 to 15 years in kitchen conditions before showing significant failure.

Is MDF better than plywood for cabinets?

Neither material is universally better they excel in different components. For cabinet box construction (sides, bottom, shelves, top): plywood is better in every practical way. MDF edge screw holding is poor (hinge screws loosen), MDF is 25 to 30 lbs heavier per sheet (adds wall mount stress), and MDF swells badly in kitchen moisture conditions. For painted cabinet door panels: MDF is better. Its grain-free surface produces the smoothest painted finish without grain telegraphing, and it routes cleanly for door profiles. Professional cabinet shops use both: plywood for structure, MDF for painted door panels.

What is OSB used for that plywood isn’t?

OSB and plywood are largely interchangeable for structural sheathing applications — OSB isn’t used for applications where plywood isn’t used. The difference is cost: OSB costs 15 to 25% less than CDX plywood at equivalent thickness and span rating, making it the dominant choice in new residential construction where cost is the primary driver. Some ZIP System and LP SmartSide products are OSB-based and include integrated weather barriers or pre-primed surfaces that add functionality not available in standard CDX plywood.

Can you use particle board for kitchen cabinets?

Technically yes — many budget kitchen cabinet lines do use particle board box construction. But it’s not recommended for a kitchen you plan to use for 20+ years. Particle board hinge screws loosen within 5 to 10 years of daily door cycling. The shelf pin holes enlarge under repeated load. The panel swells permanently from kitchen steam, condensation, and minor spills. A particle board kitchen cabinet that looks adequate in year 1 is showing visible problems by year 10 to 12. For a kitchen renovation meant to last a full 20 to 30 years, plywood box construction is the correct specification.

What’s the difference between MDF and particle board?

Both are resin-bonded wood composite panels, but they’re made from different wood waste streams and have different density profiles. Particle board uses coarser wood particles (chips and shavings) and is less dense overall. MDF uses very fine wood fibers and is pressed to higher, more uniform density. MDF has a smoother surface, routes more cleanly, and holds screws slightly better than particle board. Both fail similarly in moisture and neither should be used for structural applications. MDF is the preferred material for painted cabinet door panels; particle board is primarily used for furniture cores and flat-pack furniture.

Which is best for a shed: plywood or OSB?

For shed walls and roof sheathing, OSB is the cost-effective choice — it meets structural requirements and costs significantly less than CDX plywood. For shed interior walls where you’ll be mounting tool storage, shelving, or workshop equipment, CDX or BCX plywood is strongly preferred over OSB because screw holding at any point on the wall surface is dramatically better. OSB edge screw holding is poor, and if you’re attaching French cleat systems or heavy shelving to OSB wall panels, the fasteners won’t hold reliably.
