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.
Choosing the right door size sounds simple — until you're specifying doors across dozens of rooms, multiple suppliers, and two different measurement systems.
For anyone sourcing doors for a villa, hotel, or commercial project, understanding typical door dimensions and door height in mm isn't just a design detail. It affects installation timelines, building code compliance, and how smoothly a cross-border project comes together.
This guide breaks down standard door sizes in both millimeters and inches, explains when non-standard or custom sizes make sense, and highlights the factors that matter most when specifying doors for larger projects.
Quick Answer: What Is a Typical Door Size?
A typical interior door measures 600–910mm wide and 2040mm high (roughly 24″–36″ wide, 80″ high). The most common size used across residential and hospitality projects is 810mm × 2040mm (32″ × 80″).
Typical Door Dimensions: Width & Height (mm + Inches)
Door sizes are usually described by width first, then height. Below is a quick-reference table combining both metric and imperial standards, since global projects often need to reconcile the two.
| Width (mm) | Width (inch) | Common Use |
| 600mm | ~24″ | Closets, laundry rooms, utility spaces |
| 700mm | ~28″ | Small bathrooms, bedrooms, closets |
| 760mm | ~30″ | Most bedrooms, bathrooms, living areas |
| 810mm | ~32″ | Living-dining openings, accessible routes |
| 910mm | ~36″ | Wide openings, double-door setups |
Standard door height is more consistent worldwide:
- 2040mm (≈80″) — the most common height across residential and hotel projects
- 2100mm (≈82.6″) — increasingly common in newer builds and premium villas
- 2400mm (≈94.5″–96″) — used in high-ceiling lobbies, villas, and statement entrances
Standard Door Height in mm — A Closer Look
Door height gets less attention than width, but it varies more than people expect depending on the region and building type.
Here's how it typically breaks down:
- Europe & most residential builds: 2040mm is the default
- Newer developments & premium residential: 2100mm is becoming standard
- Hotels & hospitality (guest room doors): usually 2040mm for consistency across units
- Villas, lobbies, high-ceiling spaces: 2100–2400mm for a more dramatic entrance
The taller the ceiling, the more a standard 2040mm door can look undersized. For villas and hotel lobbies with generous floor-to-ceiling heights, matching door height to the room proportions matters just as much as matching the style.
Non-Standard Door Dimensions
Not every opening fits a standard size — and that's more common than you'd think, especially in renovations or buildings with irregular layouts.
Typical non-standard combinations include:
- 700mm × 2100mm
- 810mm × 2100mm
- 910mm × 2100mm
These sizes often appear in:
- Older buildings being renovated
- Irregular or non-standard room layouts
- Projects mixing standard and taller ceiling heights on the same floor plan
Custom Door Dimensions for Large-Scale Projects
For villas, hotels, and commercial developments, custom sizing is often the norm rather than the exception.
Here's why:
- Unified floor-to-ceiling heights across a building often don’t match off-the-shelf sizes
- Design consistency matters more in hospitality and villa projects than in a single home
- Non-standard openings are common in architect-led designs
A typical custom door workflow looks like this:
- Drawing review — confirming openings, units (mm/inch), and tolerances
- Sample approval — checking finish, hardware, and sizing before full production
- Batch production — manufacturing to the confirmed specification
- Quality inspection — verifying dimensions before shipment
- Logistics & delivery — coordinated to the project timeline
Key Factors When Specifying Door Dimensions
Before finalizing door sizes for a project, run through these six factors:
1. Floor-to-ceiling height Sets the practical upper limit for door height — and whether 2040mm, 2100mm, or 2400mm makes more sense.
2. Room function & traffic flow Guest rooms, corridors, and public areas often need different widths even within the same building.
3. Local building & fire codes Minimum width and fire-rating requirements vary by country and must be confirmed early — not after production starts.
4. Accessibility standards Many international projects require a minimum clear width (often 750mm+) for accessible routes.
5. Unit consistency across suppliers If different vendors are working in mm and inches, mismatches can slip through unnoticed until installation.
6. Budget & lead time for custom sizes Custom dimensions typically add cost and lead time compared to standard sizes — worth factoring into the project schedule early.
Common Interior Door Types
Dimensions are only half the picture — door style also affects how a space feels and functions.
| Type | Best For |
|---|---|
| Raised Panel Doors | Traditional or classic interiors; adds depth and texture |
| Flat Panel Doors | Modern, minimalist spaces; clean and simple lines |
| Hinged Doors | Most common type; suits nearly any room |
| Sliding Doors | Space-limited rooms or contemporary open-plan layouts |
Quick Reference Table: Door Sizes at a Glance
| Width (mm) | Width (inch) | Height (mm) | Height (inch) | Typical Use |
|---|---|---|---|---|
| 600 | 24″ | 2040 | 80″ | Closets, utility rooms |
| 700 | 28″ | 2040 | 80″ | Small bathrooms, bedrooms |
| 760 | 30″ | 2040–2100 | 80″–82.6″ | General residential rooms |
| 810 | 32″ | 2040–2100 | 80″–82.6″ | Living areas, accessible routes |
| 910 | 36″ | 2100–2400 | 82.6″–96″ | Wide openings, double doors |
FAQS
What is the standard door height in mm?
The most common standard door height is 2040mm (about 80"). Newer builds and premium projects increasingly use 2100mm, while high-ceiling spaces may use doors up to 2400mm.
What is the typical width of an interior door in mm?
Typical interior door widths range from 600mm to 910mm, with 810mm being the most commonly used size for general rooms and accessible routes.
How do I convert standard door sizes from inches to mm?
Multiply the inch measurement by 25.4. For example, a 32" door equals approximately 810mm. Always double-check converted figures against manufacturer drawings, since exact metric equivalents can vary slightly by supplier.
Can door dimensions be customized for large hotel or villa projects?
Yes. Custom sizing is common for hotels and villas, especially when floor-to-ceiling heights, room layouts, or design requirements fall outside standard sizes.
What door height works best for high-ceiling villas or lobbies?
For spaces with generous ceiling heights, 2100mm to 2400mm doors typically look better proportioned than a standard 2040mm door.
Conclusion:
- Getting door dimensions right — in both mm and inches — is a small detail that prevents big headaches later. For single-room renovations, standard sizes usually cover it. For villas, hotels, and multi-unit projects, custom sizing is often necessary to match ceiling heights, design intent, and local codes.
- The safest approach for any cross-border project: confirm units early, document every opening in both mm and inches, and build in extra lead time for custom sizes.
