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.

What Is a Standard Door Width?
There is no single standard door width for every building or country. In many U.S. residential product ranges, familiar nominal door leaf widths include 24, 28, 30, 32 and 36 inches. Other markets may use metric leaf widths such as 700, 800, 820, 850 or 900 mm, subject to the selected door system and project requirements.
Door leaf width is not the same as clear opening width. A door specified as a 900 mm leaf should not automatically be treated as providing a 900 mm unobstructed passage after its frame, stops and hardware are installed.
For a broader reference covering width, height and room types, use the Standard Door Sizes in mm guide.
Common Door Leaf Widths in Inches and mm
The following are familiar reference sizes, particularly in inch-based door product ranges. Their use in any particular room still depends on local requirements.
Nominal leaf width | Metric equivalent | Common planning context |
24 in | 610 mm | Closets and selected utility openings |
28 in | 711 mm | Secondary or compact internal openings |
30 in | 762 mm | Bedrooms and selected internal rooms |
32 in | 813 mm | Interior circulation and bedrooms |
36 in | 914 mm | Wider passage and entry applications |
These are nominal door leaf sizes. Do not use this table to certify accessible clearance or determine structural rough opening dimensions. For common leaf heights and thicknesses, see the door dimension chart.
Door Leaf Width vs Door Frame Width vs Clear Opening
A single doorway may have several different horizontal dimensions. The most useful specification is one that identifies which number is being measured.
Measurement | Meaning | How it is verified |
Door leaf width | Width of the movable panel | Manufacturer specification or physical leaf measurement |
Overall frame width | Outside width of the chosen frame assembly | Frame profile and approved shop drawing |
Clear opening width | Unobstructed passage with the door at the specified open position | On-site measurement using the applicable code’s method |
Jamb depth | Frame dimension across the depth of the wall | Finished wall build-up and frame profile |
Rough opening width | Unfinished structural opening that receives the frame or unit | Verified site measurements and manufacturer installation detail |
Do not apply a universal 'frame allowance' to every door. Concealed aluminum frames, timber jambs, steel frames, prehung doors and pivot systems may use different frame geometry and fitting clearances.
Why clear opening width matters
An architect may specify a nominal 900 mm door leaf, but the usable passage can be reduced by the leaf when opened, the stop, hinges and frame geometry. The actual result must be checked using the selected door set, not inferred solely from the nominal leaf width.
For conventional swinging doors on accessible routes, several codes measure clear width with the leaf opened to 90 degrees. For sliding doors, the measurement method follows the accessible passage between the relevant edges when fully open. Always use the method prescribed in the code applicable to the project.
How to Measure Door Width Correctly
For an existing doorway:
- Record the door ID and room or unit number.
- Measure the actual door leaf width, not the decorative casing.
- Identify the frame material and measure the overall frame width or check its technical drawing.
- Open the door to the required position and measure the effective clear passage under the relevant standard.
- Record finished wall thickness, frame/jamb depth and any obstructions affecting circulation.
For new construction, start by identifying the required finished clear passage, then select a compatible door leaf and frame system. Finally, coordinate the wall opening against the approved installation drawing. Do not reverse-engineer an unverified frame allowance from the desired clear width.
Jamb Depth Is Not the Same as Door Frame Width
People sometimes refer to jamb depth as ‘door frame width’, but they are different dimensions. Overall frame width runs across the doorway. Jamb depth runs through the wall thickness.
In a project with plasterboard, tile or wall cladding, the finished wall thickness can differ from the structural wall thickness. Therefore, door jamb depth needs to match the approved wall build-up. A concealed or trimless door may also require a specific frame profile and finishing sequence.
Accessible Door Clear Width: Selected International References
The figures below relate to specific accessible or building-code door provisions, not universal leaf sizes. Applicability depends on location, building use, door function and the code adopted for the project.
Market / source | Referenced clear-width provision | Application note |
United States — 2010 ADA Standards, §404.2.3 | 32 in (815 mm) minimum for applicable accessible doorways | Swing doors generally measured with the leaf open 90°, subject to exceptions and deeper openings |
Singapore — BCA Code on Accessibility 2025, §4.4.2.1 | 850 mm minimum | Applicable doorways in the accessibility code; measured between the leaf face and stop at 90° for swing doors |
Philippines — Revised BP 344 IRR (2024), Doors | 900 mm minimum clear width under the accessible-door provisions | Confirm location, measurement method and other route requirements |
Dubai — Dubai Building Code 2021, Table B.7 | 915 mm for general entry doors; 815 mm for bathrooms and toilets excluding stalls | Exit-door provisions depend on occupant load and the applicable fire/life-safety rules |
These figures are not directly interchangeable because the codes have different scopes and conditions. In particular, a minimum *clear opening* does not specify the nominal leaf size you must purchase. For hotel corridors, accessible rooms and fire exits, request approval from the project design team or local authority where required.
Door width coordination in Southeast Asian projects
Malaysia’s MS 1064 Part 4 covers coordinating sizes and preferred sizes for doorsets. Indonesia’s SNI 03-0675-1989 refers to dimensional specifications for certain timber doors and frames. These are relevant technical references, but neither should be presented as a single minimum accessible clear width for every doorway.
For Saudi Arabia, Qatar and other international projects, first identify the adopted architectural, accessibility and fire-safety documents, then check the specific door type and use. Do not invent a regional standard based solely on a common residential leaf width.
Door Width by Application: What to Check
Bedroom and living areas: Consider routine circulation, furniture movement, door swing, leaf thickness and frame clearances. A common nominal size is not a universal minimum.
Bathrooms: Check whether the room is a normal private bathroom or an accessible facility; the required usable passage and door hardware may be different.
Hotel and apartment projects: Record each room type in a coordinated door schedule so repeated doors use approved leaf widths, frame profiles and hardware consistently.
Double doors: Record each leaf width, active-leaf designation, frame and meeting stile. Where an accessible route is involved, confirm that the required active opening meets the relevant code rather than relying on combined panel width.
Sliding and concealed doors: Confirm track layout, pocket/overlap, wall framing and exact usable passage. Do not apply the single-swing-door deduction to a different system.
Width Coordination Before Factory Production
A project schedule should identify, at minimum:
Schedule field | Information to approve |
Door ID / room type | Unique reference and location |
Required clear opening | Dimension and measurement rule, if applicable |
Selected door leaf | Width, height, thickness and construction |
Frame system | Manufacturer profile, outside dimensions and jamb depth |
Door handing / swing | Direction and hardware configuration |
Wall condition | Finished wall thickness and adjacent finishes |
Rough opening | Confirmed separately in the door installation drawing |
This information should be approved by the project’s responsible design and installation teams before manufacture. For a detailed site-opening procedure, see Door Rough Opening Size and Site Measurement.

FAQS
What is the standard width of a door frame?
There is no single fixed standard door frame width. The frame width depends on the door leaf size and frame construction. For residential interior doors, common leaf widths range from 610mm to 914mm, while the overall frame width is larger than the leaf.
What width should a door frame be?
It should match the selected door leaf, the wall thickness, the frame system, and the required clear opening. The right answer depends on the application, not on one universal number.
Is 24 inches a standard door width?
Yes. A 24-inch (610mm) door is commonly used for closets, utility spaces, and some compact secondary rooms.
Is 20 inches a standard door width?
It is less common for standard interior residential use and is usually considered too narrow for many normal applications.
What is the difference between clear opening and rough opening?
The clear opening is the usable passage after installation. The rough opening is the structural wall opening prepared before the frame is installed.
Does a 900mm door need a 900mm rough opening?
No. A 900mm door leaf needs a larger opening because the frame and installation tolerances must also be accommodated.
What is the standard door width in mm?
Common standard door widths in mm include 610, 711, 762, 813, and 914mm, depending on the room type and regional convention.
What is the standard interior door frame width?
It varies by door size and frame type. A standard interior door frame is always wider than the door leaf, and the exact allowance depends on the jamb structure and installation method.
Conclusion
Specify door leaf width, overall frame width and usable clear opening as separate numbers. Then select the correct frame, hardware and installation detail before approving the project schedule. This avoids a common error: treating a nominal catalogue width as if it were the finished passage width.
