Choosing a Chinese door for export is not just a matter of picking a familiar width. The leaf, frame, and rough opening must fit together, while the destination market may use different conventions. Buyers often compare millimeters with inches, but a neat conversion cannot resolve every installation detail. Small differences matter.
What are the standard export sizes for Chinese doors? There is no single size that suits every project. Common examples include door leaves around 800 × 2,000 mm or 900 × 2,100 mm, but these are reference points, not universal specifications. Confirm whether a supplier’s measurements describe the door leaf or the complete frame. Check wall thickness, handing, threshold details, and the finished opening before approving production. A drawing helps. So does a physical sample.
This guide compares five commonly requested size ranges and explains what to verify before ordering. One important note: no source was provided for a verifiable industry expert or quotation, so I won’t invent an attribution. Instead, use this practical rule as a checklist: “Confirm the frame and opening before treating a listed size as standard.” It sounds obvious, perhaps. Yet rushed orders can overlook it. Request written dimensions, tolerances, and packing details from the manufacturer, then have the installer review them. Export sizing is precise work, and the final fit depends on more than the number on a product sheet.
For Chinese doors, “standard export size” usually describes a practical order option, not one universal specification. Common examples include 800 × 2000 mm, 900 × 2100 mm, 960 × 2050 mm, 1000 × 2100 mm, and 1200 × 2100 mm. The last size may suit a wider or paired-door opening, depending on the design. Confirm whether listed dimensions refer to the door leaf, frame, or finished opening. These are reference sizes, not a promise that every supplier stocks them.
Before approving an order, compare the drawings with the actual site opening. Measure width at the top, middle, and bottom, then check height on both sides. Note wall thickness, floor finish, frame depth, hinge position, and handing. Small differences matter. A 10 mm mismatch can complicate installation, especially where flooring or trim is already fitted. Ask for a dimensioned shop drawing and written confirmation of tolerances. I would not rely on a photo or a catalog label alone; those can leave the frame-to-opening allowance unclear. Measure twice. Door sizes vary by project, and a neat spreadsheet cannot replace a site check.
| 5 Best Standard Export Sizes for Chinese Doors: Understanding Standard Export Sizing | ||||
|---|---|---|---|---|
| Door Leaf Size (W × H) | Approximate Inch Equivalent | Typical Application | Common Leaf Thickness | Export Sizing Note |
| 610 × 2032 mm | 24 × 80 in | Compact interior openings, closets, and utility rooms | 35–40 mm | A narrow format commonly specified for space-saving interior doors. |
| 762 × 2032 mm | 30 × 80 in | Bedrooms, bathrooms, and general interior use | 35–40 mm | A frequently requested imperial-market size; confirm the finished frame opening separately. |
| 813 × 2032 mm | 32 × 80 in | General-purpose interior doors and accessible routes where suitable | 35–45 mm | Corresponds closely to a common 32-inch-wide door leaf; accessibility requirements depend on clear opening and local regulations. |
| 864 × 2032 mm | 34 × 80 in | Wider interior openings and selected residential projects | 40–45 mm | Useful where a wider leaf is specified; verify hardware, frame, and clearance requirements. |
| 914 × 2032 mm | 36 × 80 in | Main interior routes, larger rooms, and some exterior-door specifications | 40–45 mm | A common wide-door format in several export markets; exterior performance depends on the full door assembly. |
| Important: These are commonly requested export-friendly door-leaf dimensions, not a single universal Chinese standard. Actual standard sizes, nominal measurements, frame dimensions, tolerances, and required clear openings vary by destination market and project. Confirm the finished opening, handing, frame, thickness, fire or accessibility requirements, and applicable local building codes before ordering. | ||||
It usually means common order options, not one universal size. Examples include 800 × 2000 mm, 900 × 2100 mm, and 1000 × 2100 mm.
They may refer to different parts. Ask for leaf dimensions, frame outside dimensions, and rough opening measurements in writing.
Measure the width at the top, middle, and bottom. Use the smallest result. Check the height on both sides.
Note wall thickness, floor finish, frame depth, hinge position, and door handing. State whether measurements include the threshold. Small details matter.
An 800 mm leaf can suit many bedrooms. A 700 mm leaf may fit a compact bathroom, but check clear passage after installation.
A 900 mm leaf can make carrying groceries or furniture easier. Check the door swing and available wall space.
A 1000 mm leaf can create a generous entrance. It also needs more clearance. I might miss that when looking only at a floor plan.
Follow the project specification and confirmed shop drawings. A 10 mm mismatch can cause trouble when flooring or trim is already fitted.
Not by itself. Request a dimensioned drawing and written tolerances, then compare them with the actual opening. Measure twice.
What are the standard export sizes for Chinese doors? This guide explains how to compare common export dimensions while accounting for differences between markets and building requirements. It clarifies the distinction between the door leaf, frame, and rough opening, showing why these measurements should not be treated as interchangeable. It also introduces five commonly used size options and explains how the right choice depends on the intended room, building type, and practical access needs.
Before placing an order, buyers should confirm the measurement method, required clearances, manufacturing tolerances, and installation conditions with the project team. Checking these details early can help prevent fitting problems and reduce the need for on-site adjustments. Because openings and construction practices vary, the most suitable size is the one verified against the actual site dimensions and project specifications.
