Regular plywood sizes and sizes available on request
Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Write the finished sheet width × length in millimetres. The inch column is calculated using 1 inch = 25.4 mm, rounded to four decimal places.
4 ft × 8 ft converts exactly to 1219.2 × 2438.4 mm.1220 × 2440 mm is commonly called 4×8 class, not an exact mathematical equivalent. Some markets say 8×4; the written order still controls.
Ordering 5×10 plywood sheets? Exact 5 ft × 10 ft is 1524 × 3048 mm. Our regular 1525 × 3050 mm format is slightly larger; specify the finished size your cutting layout or frame needs. For wholesale 4×8 or 5×10 orders, include quantity by thickness, construction and destination so our factory can confirm the production quantity, packing and quotation.

For a US structural-panel order, 15/32, 19/32 and 23/32 may identify a performance category. The arithmetic values above do not define its permitted measured thickness or replace its grade, span rating and product documents. See US plywood grades and performance categories and APA thickness-label guidance. The unit conversion follows NIST’s definition of the inch.
Specify the ordered and measured thickness
State the nominal product name, the finished manufacturing target and the agreed measurement tolerance together. For calibrated plywood, include the sanding, surface and finished fit required by your component; overlays also affect the measured thickness.
Order 18 mm as 18 mm; use 3/4 in when the inch-based product system is required.
- Trade size label
- A familiar phrase used to find or discuss a panel; it may combine nearby but non-identical products.
- Nominal thickness
- The order or market designation used for a product system; it does not by itself state every measured value.
- Manufacturing target
- The specified finished-panel target that production is asked to achieve.
- Measured actual
- Observed values taken on the finished panel under the agreed method and condition.
- Acceptance tolerance
- The permitted relationship between ordered target and measured values, including sampling and decision rule.
- Performance category / standard label
- A label used only inside the named product and standard system; it is not a global metric equivalent.
- Finished-panel definition
- States sanding, unsanded condition, overlay and any machining that affect what is measured.
APA Performance Categories such as 23/32 belong to the specific North American performance-rated panel system. They do not redefine 18 mm plywood worldwide, and an APA trademark applies only within the corresponding member-mill and standard context.
Measure the finished sheet consistently
For a repeatable inspection, agree the finished-panel condition, sampling points, calibrated tools and acceptance tolerance in the order. Length, width, thickness, squareness, straightness and flatness are separate checks.
- Name the applicable product standard or agreed measurement method.
- State the moisture condition of the finished panels at measurement.
- Use a calibrated thickness gauge and measuring tools suited to the sheet size.
- Measure finished thickness, length and width separately.
- Check edge straightness, squareness and flatness where the application requires them.
- Agree the number and positions of measurements and the permitted variation.
- Record results by production lot with the tool, date and measured panel identified.
- Thickness tolerance and variation
- Specify the permitted finished minimum and maximum, with positions across the sheet and sampling quantity. Include sanding, calibration and overlays. For grooves, inserts and hardware, agree the fit your workshop needs rather than ordering by a nominal label alone.
- Squareness and edge straightness
- Define the check required by your drawing or product standard, including diagonal or edge measurements and their permitted deviation. Identify reference edges and whether the limit applies to a full sheet or a machined part.
- Flatness tolerance
- Agree panel conditioning, the supporting surface or span, measurement locations and permitted gap under the specified straightedge or reference plane. Flatness measured on defined supports is different from sag in an unsupported thin sheet.
Include the applicable product standard or written tolerance schedule in the quotation. Sanding and overlays affect which finished surfaces are measured.
THICKNESS MEASUREMENT
Measure between the finished faces.
Choose the thin panel around your finished part
For a 2 mm, 3 mm or other thin plywood requirement, give the finished thickness, face and core species, individual veneer thicknesses and ply count. The same overall thickness can use different lay-ups; choose the construction for your cutting, forming and assembly.
Precision-cut flat parts
Plan sheet flatness, support and hold-down with slot widths, joints and reference edges. Agree the finished fit after cutting, not just the nominal sheet thickness.
Choose laser-cutting plywoodUltra-thin veneers and components
Specify each veneer and grain direction with the finished thickness, tolerance and component drawing. For an aircraft part, use its required material specification and project qualification documents; thinness alone does not establish suitability.
Explore aircraft and ultra-thin plywoodCurved parts and coverings
State the forming direction, curve radius, supporting surface and finish. Match the bending construction to the part rather than assuming every thin sheet forms the same way.
Choose flexible plywoodKeep fine face veneers protected during sanding, cutting and transport. Request a physical panel for machining or fit checks, with the construction, thickness and destination specified; we confirm availability, sample and courier costs before dispatch.
Request a panel for your fit checkMark the face grain and strength axis
Show grain direction with an arrow relative to the stated width and length. For structural panels, use the declared strength axis; for furniture and decorative panels, specify the required visible grain orientation.
- Plywood face grain runs in a defined direction across the sheet.
- Specify face-grain direction for visible veneer, furniture panels and cut parts.
- For structural plywood, identify the product's declared strength axis and installation orientation.
- Laser cutting and patterned overlays may need a specific face or machining direction.
- Add a grain arrow to the drawing and relate it to width and length.
- Match the ordered panel and installation details to the applicable structural design when load-bearing use is intended.
Choose dimensions for the plywood type
The regular factory sizes below are the starting point for your order. On request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Choose your core, surface and thickness, then send the sizes and quantities you need for a factory quotation.

Calculate area, volume and estimated sheet weight
Use finished dimensions for quantity planning and your chosen construction's density for weight estimates. Add pallets and protection separately when planning transport.
Panel area
width(mm) × length(mm) ÷ 1,000,000Result unit: m²
Volume per sheet
area(m²) × thickness(mm) ÷ 1,000Result unit: m³
Estimated net panel mass
volume(m³) × agreed density(kg/m³)Result unit: kg
Worked volume example
1220 × 2440 × 18 mm → 2.9768 m² × 18 ÷ 1,000 = 0.05358 m³ per sheet.
Insert the density agreed for the selected construction; packaging mass is added separately. Mixed-thickness orders are calculated by size and thickness, then summed. Planning mass is not a container payload or freight quotation.
Protect and support the full sheet
Specify a pack base sized for the panels, aligned bearers, face and edge protection, lifting access and the receiving equipment at the destination.
- Support the full panel footprint.
- Set bearer number, spacing and alignment for the packed sheet size.
- Add top and bottom protection sheets.
- Choose moisture protection suited to the journey and storage conditions.
- Protect edges and corners while keeping the faces clean.
- Position straps over protectors so tension does not mark or deform the panels.
- Leave suitable fork or spreader access for the packed mass.
- Check the packed dimensions against vehicle opening, payload and receiving equipment.
LARGE-SHEET PACKING
Support the complete panel footprint.
Order full sheets or parts to your dimensions
Start with what you make, the finished dimensions, quantity by thickness and destination. Our CUZI PLY factory helps complete the construction, finish, machining and packing details. Add a drawing when grain direction or cutting orientation matters.
Compare regular-sheet cutting yield with a custom sheet or factory-finished parts. We confirm minimum production quantity, compatible size and thickness mix, price basis and production time with your quotation; shipping and destination handling are planned separately. Custom width and length belong in your order, while product documents follow the relevant construction, performance and intended use.
Order cut-to-size plywood or CNC plywood components, with edge banding where the component needs a finished edge.

Before the purchase order
Choose the right specification.
Can I order custom plywood dimensions instead of a regular sheet size?
Yes. Share the finished width, length, thickness, product construction and quantities, together with any grain direction, tolerance or cutting requirements. We confirm the available manufacturing format, order quantity, processing, packing and price. Compare a custom sheet with regular-sheet cutting yield before choosing the most useful option.
Which thickness should I specify for grooves, hardware or fitted parts?
State the required finished thickness and tolerance, not only a nominal label or nearby inch fraction. Include overlays, sanding and other finishing that affect the finished measurement. Trial the actual joint or hardware fit where it matters, then keep the agreed dimensional requirements with the order.
Will a larger plywood sheet always reduce my total cost?
A larger format can improve cutting yield or reduce joints, but compare material price, nesting, processing, pack dimensions and weight, freight and unloading equipment as well. Send the part layout and quantities to our factory. We can discuss available formats and the supply costs for your chosen construction.
What is a standard plywood sheet size?
Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Tell us your preferred size, thickness and quantity; we will confirm production and export packing for your order.
Is 4×8 plywood exactly 1220×2440 mm?
An exact 4 ft × 8 ft sheet is 1219.2 × 2438.4 mm. The familiar 1220 × 2440 mm sheet is slightly larger in both directions, so write the required finished dimensions in the order.
Does width or length come first in a plywood order?
This guide uses width × length × thickness, followed by the unit. For cut parts or visible veneer, add a drawing arrow showing face-grain direction; for structural panels, identify the declared strength axis.
Is 18 mm plywood the same as 3/4 inch plywood?
18 mm converts to 0.7087 in. A true 3/4 in thickness is 19.05 mm, a difference of 1.05 mm. Specify the finished target and tolerance needed by the joint, machining process or panel system.
What is nominal versus actual plywood thickness?
Nominal thickness is the product's ordering designation. The manufacturing target is the specified finished thickness, and actual thickness is measured on the completed sheet. Agree the tolerance and measurement condition for sanded or overlaid panels.
Which tolerance should be specified?
Specify separate limits for finished thickness, length, width, squareness, straightness and flatness as your use requires. Include the measurement method, sampling quantity and applicable product standard or written drawing with the order.
Can every plywood product be supplied in oversize sheets?
Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Tell us your preferred size, thickness and quantity; we will confirm production and export packing for your order. Send the plywood type, exact sheet dimensions, thickness and quantity for a project quotation.
How are 1250×3660, 1250×3800, 1525×3050 and 2100×2800 mm supplied?
Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Tell us your preferred size, thickness and quantity; we will confirm production and export packing for your order. The quotation covers press and material capacity, finished thickness, flatness, pack support, calculated mass, vehicle opening and unloading equipment.
How should face grain or strength axis be stated?
Mark the direction with an arrow on the panel drawing and identify it relative to the listed width and length. The structural strength axis follows the declared product properties; a decorative panel may instead follow visible-grain or cutting requirements.
What information is needed for an oversize plywood quotation?
Provide the plywood type and use, width × length × thickness with units, quantity by size, surface and edge finish, grain direction, finished tolerance, destination, unloading method and any required packing or testing documents.
