In the pursuit of personalized spaces and premium living, mass-produced furniture often falls short of capturing the true essence of a home.
As modern minimalism and light luxury styles continue to dominate global design trends, high-end custom furniture has become the absolute core of creating an ideal living space.However, the custom furniture market can be highly complex.
Bridging the gap between a stunning design blueprint and the final product involves navigating materials, hardware, and craftsmanship. Here is how to choose bespoke luxury furniture like a professional designer.
Quick Answer
What Is a Standard Door Size in mm?
There is no single standard door size for every country, building or room. As a general planning reference, many residential interior doors are approximately 700–900 mm wide and 2000–2100 mm high. In inch-based markets, frequently listed nominal door leaf sizes include 30 × 80 inches (762 × 2032 mm) and 32 × 80 inches (813 × 2032 mm).
These dimensions describe commonly encountered product sizes—not universal legal minimums. The final specification must consider the door type, local rules, accessibility, frame construction, hardware and approved architectural door schedule.
Size Chart
Standard Door Size Chart in mm
Use this table to compare common reference dimensions, rather than mandatory standards. Width and height generally refer to the door leaf unless otherwise stated.
Door type | Reference leaf width | Reference leaf height | Typical leaf thickness |
Bedroom door | 750–900 mm | 2000–2100 mm | 35–45 mm |
Bathroom door | 700–800 mm | 2000–2100 mm | 35–40 mm |
Kitchen / internal passage | 800–900 mm | 2000–2100 mm | 35–45 mm |
General interior door | 750–900 mm | 2000–2100 mm | 35–45 mm |
Main entrance door | 900–1200 mm | 2100–2400 mm | System-dependent |
Double-leaf door | 1200–1800+ mm combined | Project-specific | System-dependent |
The thickness ranges are examples seen in some non-rated door products. Fire-rated, acoustic, glazed, security and oversized doors require their own tested door-set specifications. A reference width is not proof that an accessible passage requirement has been met
Bedroom, bathroom and entrance door sizes
- Bedroom doors: The selected leaf width should accommodate regular circulation and furniture movement. The door swing, frame and surrounding cabinetry can affect the usable passage.
- Bathroom doors: Compact designs may use narrower leaves, but accessible bathrooms and public projects can require greater clear opening width. Check the applicable code rather than selecting solely from a typical residential range.
- Kitchen and passage doors: Consider appliance movement, circulation routes and door swing clearances. The appropriate width depends on whether the doorway serves a private room or an accessible route.
- Entrance and double doors: The opening arrangement, security hardware, threshold, load and applicable egress rules often matter more than the nominal size alone.
Door Height
Common Door Heights: 2000, 2032, 2040, 2100 and 2400 mm
Door heights vary with the regional product system and architectural design. The following are planning references:
Door leaf height | What it usually represents |
2000 mm | A metric height used in selected residential projects |
2032 mm | Exactly 80 inches; familiar in U.S. nominal interior door sizing |
2040 mm | A commonly offered metric door leaf height in some markets |
2100 mm | Frequently specified in contemporary metric projects |
2400 mm | A taller project-specific door requiring frame and hardware coordination |
A taller door is not automatically compatible with the hinges used on a shorter one. For high or heavy leaves, verify leaf construction, hinges or pivots, frame reinforcement and installation conditions with the selected door-system manufacturer.
Custom Sizing
How Door Dimensions Differ by Country and Market
Standard sizes are useful for planning, but many projects require custom dimensions because of architectural openings, ceiling heights, existing structures or design intent.A dimension commonly stocked in one country may be a special-order size in another. This is particularly important when architects, contractors and suppliers use different measurement systems.
Market | Useful planning reference | What needs checking |
United States | Nominal 30 × 80 and 32 × 80 inch interior leaf sizes are common examples | Actual leaf, frame, egress and accessible clear width requirements |
United Kingdom | 1981 mm is a familiar nominal interior door height in selected product ranges | Specific manufacturer range and applicable building requirements |
Australia | 2040 mm is a common nominal leaf height in selected product ranges | State/territory rules, project documents and selected door set |
Malaysia | MS 1064 Part 4 addresses coordinating and preferred sizes for doorsets | Which dimensional system the architectural schedule calls for |
Indonesia | SNI 03-0675-1989 covers dimensions of certain timber door leaves and frames | Scope of the standard, current project specification and frame system |
Southeast Asia / Middle East | Projects commonly use metric dimensions, but not one regional standard | Door use, accessibility, fire/egress requirements and local authority approval |
Important: A country’s minimum accessible clear width is not its universal door leaf size. For example, a code may require a clear passage measured with the leaf open, and the actual leaf often needs to be wider than that passage.For a comparison of door leaf width, frame width and legally relevant clear width, read Standard Door Width & Frame Size: Leaf vs Clear Opening.
Need a Custom Door Size for Your Project?
Standard dimensions are useful for planning, but the final door should match the actual opening, wall thickness, frame system, hardware preparation and approved project drawings. BoyceCasa manufactures custom interior doors for villas, apartments, hotels and other residential or commercial projects.
Door Leaf, Door Frame, Rough Opening and Clear Opening
These four terms appear together in project schedules, but they describe different dimensions:
Measurement | Short definition |
Door leaf size | The finished movable door panel’s width and height |
Overall frame size | The outside dimensions of the selected door frame assembly |
Rough opening | The unfinished structural opening that receives the frame or door unit |
Clear opening | The unobstructed passage remaining with the door in its required open position |
A 900 mm door leaf does not necessarily provide 900 mm clear width, and the rough opening must be determined from the selected complete door system rather than from the leaf alone.
For measurement details, continue to Door Width, Frame Size & Clear Opening. For framing and site allowances, see the Door Rough Opening Size Chart and Site Measurement Guide.
Project Applications
When Does a Project Need Custom Door Sizes?
Standard reference dimensions help in early planning, but custom fabrication can be necessary when a project has full-height doors, concealed frames, unusual wall thickness, existing renovation openings, coordinated wall panels, oversized entrances or repeated hotel and apartment room types.
Before confirming manufacture, a project team should review the approved door schedule for leaf size, frame system, wall construction, finish floor level, hardware, finish and any fire, acoustic or accessibility requirements. Those requirements cannot be established from a general room-size chart alone.
Door Leaf Size
The finished movable panel dimension.
Frame Size
The overall dimensions of the door frame system.
Rough Opening
The structural wall opening before frame installation.
Clear Opening
The actual usable passage width after installation.
Hardware Preparation
Hinge, pivot, closer, lock and access-control positions.
From Door Size to Production Specification
For project orders, nominal door size is only the starting point. Final manufacturing dimensions should be confirmed from the approved door schedule, wall condition and hardware requirements before production.
| Before Production | Confirm |
|---|---|
| Door Leaf | Finished width × height |
| Frame | Overall size and depth |
| Wall | Finished wall thickness |
| Opening | Rough opening and clear opening |
| Hardware | Hinge, pivot, lock and closer preparation |
| Finish | Veneer, lacquer, WPC, glass or other specified surface |
For repeated apartment or hotel units, the same approved specification should be reproduced consistently across room types and floors.
Specification
Key Factors When Specifying Door Dimensions
Room Function
Bedroom, bathroom, entrance and service doors have different circulation and privacy requirements.
Clear Opening
The nominal door leaf width is not always the same as the usable passage width.
Wall Thickness
Frame depth should correspond to the finished wall construction.
Finished Floor Level
Tile, stone, timber flooring and thresholds affect the final opening height.
Door Weight & Hardware
Oversized doors may require stronger hinges, pivot systems or reinforced frames.
Codes & Accessibility
Fire, escape, accessibility and building regulations may determine minimum dimensions.
Measurement Terms
Door Size vs Frame Size vs Rough Opening
Door Leaf
The movable door panel.
Door Frame
The structural frame surrounding the leaf.
Rough Opening
The wall opening prepared before installation.
Clear Opening
The usable passage after installation.
A 900 mm door leaf does not require a 900 mm rough opening. Additional allowance is required for the frame, installation and adjustment.
Door Types
How Door Dimensions Change by Door Type
| Door Type | Size Consideration |
|---|---|
| Flush Door | Usually follows conventional interior openings. |
| Hidden Door | Must coordinate frame and wall panel alignment. |
| Pivot Door | Often wider or taller and requires hardware calculation. |
| Sliding Door | Opening width depends on panel overlap and track system. |
| Glass Door | Glass size depends on frame and hardware configuration. |
| Double Door | Requires total opening and individual leaf dimensions. |
Different door systems require different frame, opening and hardware allowances. Explore the relevant system before finalizing project dimensions.
