Plywood Sizes & Thickness — Vietnam Factory Spec Guide

When an international buyer requests a plywood quotation in 2026, the first two questions are always the same: what plywood sizes and thickness do you need? These two parameters determine everything that follows — how many sheets fit on a pallet, how many pallets fit in a 40HC container, what the shipment weighs, what freight costs, and whether the plywood performs correctly in the buyer’s application. Getting sizes and thickness wrong at the specification stage cascades into production errors, container loading inefficiency, and avoidable cost.

This guide provides factory-level specifications for plywood sizes and thickness as manufactured by HCPLY in Vietnam. Every number in this article comes from verified 2026 production data — standard sizes, thickness steps, tolerance limits, ply count by thickness, weight per sheet by core species, and container loading calculations. Use this as your reference when specifying plywood dimensions for any application.

⚠️ Note: All specifications in this guide are based on HCPLY production standards and verified factory data. We do not fabricate technical specifications. Density values are core-species dependent. Weight calculations use actual measured densities, not marketing estimates.

“Buyers who specify plywood sizes and thickness correctly on the first inquiry receive accurate quotes within 12 hours. The most common delay is missing the core species — without it, we cannot give you weight or container loading numbers.” — Ms. Lucy Pham, International Sales Manager, HCPLY

📐 Standard Plywood Sheet Sizes

Two sheet sizes account for the vast majority of plywood production in Vietnam and global trade. Understanding why both exist — and which one to specify — directly affects your procurement efficiency.

1220 x 2440 mm

The 1220 x 2440 mm sheet is the most widely produced and traded plywood size in the world. Originating from the imperial measurement system (4 feet by 8 feet), this format is the default specification across North America, India, the Middle East, Southeast Asia, Africa, and Latin America.

For international buyers, this size integrates with standard construction grids (4-foot module spacing for stud walls, ceiling panels, and subfloor layouts), standard pallet dimensions, and standard container loading configurations. When you request a quotation without specifying a size, the factory assumes 1220 x 2440 mm.

1250 x 2500 mm — The Metric Standard

The 1250 x 2500 mm sheet serves markets that operate on metric dimensions — primarily Europe (Germany, France, Spain, Poland, Netherlands), Korea, and Japan. This sheet is 30mm wider and 60mm longer than the 4x8 format, producing approximately 5% more panel area per sheet.

For European furniture factories, this size eliminates the waste that occurs when cutting 1220 x 2440 mm sheets to metric production dimensions. European formwork systems, cabinet carcass dimensions, and building board specifications are metric-native — ordering 1250 x 2500 mm avoids conversion losses.

Size Comparison Table

⚠️ Key point: Both sizes load the same number of pallets per 40HC container. The 1250 x 2500 mm format produces more CBM per container because each sheet has a larger area — not because more sheets or pallets fit in the container. This distinction matters when calculating freight cost per CBM.

📏 Additional and Custom Plywood Sizes

Beyond the two primary formats, HCPLY manufactures several secondary sizes for specific applications.

Custom cutting is available from HCPLY with the same minimum order of one 40HC container. Buyers with specific crate templates, pallet designs, or non-standard construction modules can provide a cut list. HCPLY’s production team optimizes the cutting layout from standard parent sheets to minimize waste and maximize usable pieces per container.

For packing plywood specifically, the 1220 x 1830 mm and 915 x 1830 mm formats are popular because they match common pallet and crate dimensions directly — reducing the buyer’s need for secondary cutting at their facility.

📊 Thickness Range and Common Steps

HCPLY manufactures plywood across a thickness range of 3 mm to 40 mm. Within this range, specific thicknesses are standardized because they correspond to the most common applications in furniture manufacturing, construction, and industrial packaging.

Standard Thickness Steps

18mm is the most commonly ordered single thickness across all plywood types and markets. It represents the optimal balance between structural strength, weight, container loading efficiency, and cost. For buyers ordering their first container of plywood from Vietnam, 18mm is the standard starting point.

📌 Important: Thickness between standard steps (e.g., 4mm, 7mm, 8mm, 10mm, 14mm, 16mm, 20mm) can be manufactured on request. Non-standard thicknesses require minimum container volume and may carry a production scheduling premium. Confirm availability with HCPLY before ordering.

🔧 Ply Count by Thickness

Plywood is constructed from an odd number of cross-laminated veneer layers (plies). More plies at a given thickness means thinner individual veneers — which improves dimensional stability, reduces warping tendency, and creates a more balanced panel.

The ply count depends on both the finished panel thickness and the core veneer thickness used during layup. HCPLY standard core veneer thickness ranges from 1.5 mm to 1.7 mm per ply.

Ply Count Reference Table

Why ply count matters for buyers:

• Furniture applications: Higher ply count at a given thickness produces panels with better screw-holding at panel edges and less tendency to warp when exposed to humidity variation. A 12mm 9-ply panel outperforms a 12mm 7-ply panel in edge screw retention.
• Formwork applications: Consistent ply count means consistent load distribution across the panel face. Uneven ply thickness creates weak zones that cause deflection under concrete load.
• CNC routing: Panels with consistent ply thickness route cleaner because the cutting tool encounters uniform material density across the panel cross-section. Inconsistent plies create chatter and tear-out.

For detailed information on core veneer species and their effect on panel properties, see the plywood core types guide.

📐 Dimensional Tolerance — What Buyers Must Specify

Tolerance is the allowed deviation from the specified dimension. It is one of the most overlooked specifications in plywood procurement — and one of the most common sources of quality disputes.

HCPLY Standard Tolerances

Thickness Tolerance: Why ±0.3mm Is the Standard

The ±0.3mm thickness tolerance is the production standard for calibrated plywood in Vietnam. This tolerance is achieved through calibration sanding — a wide-belt sander passes over the panel surface to bring it within specification. The tolerance applies across the full panel area, measured at five reference points (four corners plus panel center).

For applications that require tighter tolerance:

• Furniture and cabinet manufacturing: ±0.2mm is achievable through additional calibration sanding passes. This tighter tolerance is recommended for edge-banded panels, CNC-routed components, and lamination substrates where consistent thickness prevents visible joint lines.
• Film faced plywood: The film overlay is applied directly to the calibrated panel surface, so thickness tolerance of the base panel determines the formwork surface uniformity. ±0.3mm is standard for construction formwork.
• Packing plywood: Thickness tolerance is less critical for industrial packaging. ±0.5mm is acceptable for most crate and pallet applications where structural integrity matters more than dimensional precision.

⚠️ Heads up: Always specify your required thickness tolerance in the purchase order. If you do not specify, the factory defaults to ±0.3mm. Requesting tighter tolerance after production has started is not possible — calibration is set during the sanding line setup. See the quotation guide for the full specification checklist.

⚖️ Weight per Sheet — Calculation by Core Species

Sheet weight is determined by core species density, not face veneer type. A birch plywood panel with styrax core weighs the same as an okoume plywood panel with styrax core at the same thickness and size — because the face veneer is only 0.2–0.4mm thick and contributes negligible weight compared to the core.

Core Species Density (Source of Truth)

Weight Calculation Formula

Weight (kg) = Length (m) × Width (m) × Thickness (m) × Density (kg/m³)

Example: 18mm birch plywood with styrax core, size 1220 x 2440 mm:

Weight = 1.22 × 2.44 × 0.018 × 500 = 26.8 kg per sheet

Weight table (1220 × 2440mm):

Weight table (1250 × 2500mm):

Why weight matters for importers:

• Container payload limit: The 40HC container has a maximum payload of 28.5 MT (metric tons). Heavier core species (eucalyptus) hit this limit with fewer pallets than lighter species (styrax). Weight per sheet determines your total container weight — and whether you can add another pallet or not.
• Freight cost: Ocean freight is charged by weight or volume, whichever is greater. Knowing your shipment weight enables accurate freight quotation requests.
• Arrival verification: Weighing sample panels on arrival confirms that the core species matches the specification. If you ordered styrax core at 18mm and the panel weighs 37 kg instead of 27 kg, the factory shipped eucalyptus core.

For complete container loading calculations by core species and thickness, see the plywood container packing calculation guide.

📦 Sheets per Pallet and Pallets per 40HC Container

Container loading is where plywood sizes and thickness translate into logistics cost. The number of sheets per pallet depends on thickness. The number of pallets per container depends on core species density and the 28.5 MT payload limit.

Sheets per Pallet (Standard 1000mm Stack Height)

Pallet stack height is standardized at 1000mm across HCPLY production — this height is forklift-safe, structurally stable, and optimizes the internal height of a 40HC container.

Pallets per 40HC Container by Core Species

Container pallet layout: 16 pallets lie flat in a 4x4 grid configuration. For styrax core (18 pallets), the additional 2 pallets stand upright at the container door end. All configurations stay within the 28.5 MT payload limit.

Total Sheets per 40HC (18mm Example)

📌 Key note: Styrax core delivers 20% more sheets per 40HC container than eucalyptus core at the same thickness — 990 vs 825 sheets at 18mm. For buyers where freight cost per sheet is the primary concern, styrax core offers the most efficient container loading. For buyers requiring maximum panel density and stiffness, eucalyptus plywood is the correct specification despite lower sheet count per container.

HCPLY accepts mixed thickness orders within a single container. Buyers can combine 9mm, 12mm, 15mm, and 18mm panels in one shipment. Each thickness is palletized separately with clear bundle marking. HCPLY provides a detailed container packing list with bundle-level breakdown for each thickness.

🌍 Size Requirements by Market

Different export markets have evolved distinct size preferences based on their construction systems, manufacturing standards, and historical measurement conventions.

Market-Specific Size Preferences

Which Size Should You Order?

Order 1220 x 2440 mm if your end market, your customers, or your production line is set up for imperial-origin dimensions. This is the safe default for most global markets.

Order 1250 x 2500 mm if you are supplying European furniture factories, European construction sites, or Korean/German markets where metric dimensions are the native standard. The 5% larger sheet area means fewer cuts and less waste in metric production environments.

Mixed sizes in one container are accepted by HCPLY, though most buyers standardize on one size per order to simplify their own inventory management.

🏗️ Size and Thickness Requirements by Application

The correct plywood size and thickness depends on what the plywood will be used for. This section maps common applications to their typical size and thickness specifications.

Furniture Manufacturing

Key spec: Furniture plywood requires sanded surface finish, E0 or E1 emission class, and Melamine (MR) glue. Face veneer options for furniture include birch (D/E/F grade, EU market), okoume (light golden-pink, marine and furniture), and EV plywood (engineered veneer, uniform modern look).

Construction and Formwork

Key spec: Construction plywood requires unsanded surface (film overlay applied directly), WBP Phenolic glue, and is typically not rated for indoor emission standards. Film faced plywood is the standard product for concrete formwork. Anti-slip plywood is specified for platforms and truck floors.

Industrial Packaging

Key spec: Packing plywood uses unsanded Bintangor C/D or Poplar face, Melamine (MR) glue, E2 emission class. ISPM 15 fumigation is mandatory for all wood packaging materials in international trade. Starting from $220/CBM FOB Vietnam.

📊 How Thickness Affects Price, Weight, and Container Loading

Thickness is the single most impactful variable in plywood procurement economics. It affects four cost dimensions simultaneously.

1. Material Cost (Price per CBM)

Thicker panels require more raw material — more core veneer layers, more glue per sheet, and longer hot-press cycle time. However, the price increase is not linear with thickness. The fixed costs of face veneer, sanding, and quality inspection are spread across a thicker panel, so the price per CBM actually decreases slightly as thickness increases for the same product specification.

For buyers comparing specifications: a 9mm panel does not cost exactly half the CBM price of an 18mm panel. The 9mm panel’s per-CBM price is typically 10–20% higher because the production process requires the same number of sanding passes, QC inspections, and face veneer sheets regardless of panel thickness.

2. Weight per Container

As thickness increases, the weight per sheet increases proportionally — but the number of sheets per pallet decreases (fewer sheets fit in the 1000mm pallet stack). The net effect: total container weight stays relatively constant across different thicknesses for the same core species, because the payload limit (28.5 MT) is the binding constraint.

Pallet weight remains nearly constant at approximately 1,475–1,490 kg per pallet (styrax core) regardless of thickness. This is not coincidence — it is a direct consequence of the 1000mm stack height standard.

3. CBM per Container

CBM per container also stays relatively constant for the same core species because the number of pallets is determined by payload weight, not by thickness. The CBM of a single pallet changes with thickness, but the pallet count is fixed by the weight limit.

4. Structural Performance

Thicker panels resist bending, deflection, and concentrated loads better than thinner panels of the same core species. The relationship between thickness and stiffness is not linear — stiffness increases with the cube of thickness. An 18mm panel is approximately 2.4 times stiffer than a 12mm panel, and an 18mm panel is approximately 8 times stiffer than a 9mm panel.

For furniture plywood, thickness determines shelf deflection under load, drawer front rigidity, and table top flatness. For film faced formwork, thickness determines how far the panel deflects between support beams when loaded with wet concrete — a critical safety and quality parameter.

🔍 Special Considerations: 1220x2440 vs 1250x2500 in Practice

Buyers frequently ask whether the two sizes are interchangeable. The answer is nuanced.

Production line setup: Most Vietnam factories (including HCPLY) can switch between the two sizes. The veneer layup, pressing, and trimming equipment accommodates both dimensions. Switching adds a minor setup time — not enough to affect pricing or lead time for container-quantity orders.

Container loading: Both sizes load the same number of pallets per 40HC. The 1250x2500mm sheets produce slightly wider and longer pallets, but the 40HC container internal dimensions (12,032mm length x 2,352mm width x 2,698mm height) accommodate both formats in the same 4x4 pallet layout. The difference is that 1250x2500mm pallets load approximately 5% more CBM per container.

Price difference: The FOB price per CBM is typically identical for both sizes. The cost per sheet is slightly higher for 1250x2500mm because each sheet contains more material (3.125 m² vs 2.977 m²). But per-CBM pricing — which is how plywood is commercially quoted — does not change with sheet size.

Mixing sizes in one container: Technically possible, but not recommended. Mixed-size pallets complicate the loading geometry and waste container space at the pallet boundary. HCPLY recommends ordering one size per container for optimal loading efficiency.

❓ Common Buyer Questions on Plywood Sizes and Thickness

“Can I order 2.5mm plywood?”

2.5mm is below HCPLY’s standard minimum of 3mm. Ultra-thin plywood at 2.5mm requires specialized pressing equipment and is typically sourced from factories specializing in thin-panel production. For backing panels and lightweight applications, 3mm is the recommended minimum thickness from HCPLY.

“What is the maximum thickness available?”

HCPLY standard maximum is 30mm. Panels up to 40mm can be produced for specific industrial applications on request. Thicknesses above 30mm require extended production lead time and higher MOQ.

“Does face veneer type affect the available sizes?”

No. All face veneer types — birch, okoume, bintangor, gurjan, pine, poplar, eucalyptus, EV, film faced, anti-slip, matt — are available in both 1220x2440mm and 1250x2500mm sizes, and in the full thickness range appropriate for each product.

“Can different thicknesses be mixed in one container?”

Yes. HCPLY accepts and regularly ships mixed-thickness containers. Each thickness is palletized separately and labeled. A single container can include 9mm, 12mm, 15mm, and 18mm panels — all with the same face and core specification, or with different specifications per thickness. HCPLY provides a bundle-level packing list for mixed containers.

“How does plywood thickness affect import duty classification?”

Plywood is classified under HS code 4412 regardless of thickness. However, some countries apply different duty rates based on thickness ranges (e.g., plywood over 6mm vs under 6mm may carry different rates in certain markets). Check your destination country’s tariff schedule or consult with HCPLY’s export team for guidance specific to your market.
