Quick answer
What is the standard door size?
A standard interior door is about 81 cm (32 inches) wide and 203 cm (80 inches) tall in the US and Canada. UK interior doors are ~76 cm (30 in), EU doors ~86 cm (34 in), and Australian doors ~82 cm (32 in). The real clear opening is usually 2–5 cm narrower than the door slab.

Quick lookups
Door size examples for quick fit checks.
Standard door width in cm
Most US interior doors are listed as 32 inches wide, which is about 81 cm before trim and stops reduce the clear opening. UK interior doors are commonly 762 mm wide, or about 76 cm, while many European interior doors are closer to 86 cm. If you are checking a sofa, washer, or bookcase, use the clear opening instead of the brochure size.
Standard door height in cm
A typical US interior door is 80 inches tall, or about 203 cm. UK doors are often 198.1 cm tall, and common European sizes are around 210 cm. Japan can be closer to 200 cm depending on the building age and door type, so tall wardrobes and assembled bookcases need a real tape-measure check.
Average door size in cm for fit checks
For a quick furniture fit check, treat 81 x 203 cm as the common US interior target, 91 x 203 cm as a generous US entry door, 76 x 198 cm as a common UK interior target, and 86 x 210 cm as a common EU interior target. Subtract 2-5 cm for the actual clear opening if the door slab stays on its hinges.
Fit at a glance
Will common furniture fit through a standard door?
A standard US interior door is 32 in (81 cm) and a standard entry door is 36 in (91 cm). Here is how common furniture and appliances compare. Tap an item to run the exact fit check for your measurements.
| Item | Typical size | Through 32″ interior | Through 36″ entry |
|---|---|---|---|
| Three-seat couch | 35–38 in deep (89–97 cm) | Usually — tilted on edge | Yes |
| Refrigerator | 30–36 in wide (76–91 cm) | Tight — often needs doors removed | Usually |
| Queen mattress | 60 in wide (152 cm) | Yes — flexed on edge | Yes |
| Washing machine | 27 in wide (69 cm) | Yes | Yes |
| Dresser | 30–60 in wide (76–152 cm) | Usually — lead with the narrow side | Yes |
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01The clear opening of the door, not the frame. A 36-inch door gives roughly 32 inches once the slab and stops are accounted for.
- 02The door height, since tall pieces and appliances can clear the width but catch on the header.
- 03The item's smallest dimension and its diagonal, which decide whether tilting it on edge gets it through a narrow opening.
- 04Whether the slab and hinges can be removed, which buys back one to two inches on a tight entry door.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Measuring the frame instead of the clear opening, then losing two inches you assumed you had.
- ⚠Comparing a nominal door size against a nominal item size, when both have feet, arms, or stops that change the real numbers.
- ⚠Assuming every country uses the same standard. A UK or EU interior door is sized differently from a US one.
- ⚠Overlooking the accessibility minimum clear width on doors that must meet code.

Frequently asked
Questions we keep getting.
What is the standard door size in the US?
US interior doors are typically 32 inches wide by 80 inches tall. Exterior (entry) doors are 36 inches wide by 80 inches tall. These dimensions follow the International Residential Code (IRC R311.2).
01Are European doors the same size as American doors?
No. European doors follow DIN or EN standards and are measured in millimeters. A standard European interior door is 860 mm wide (about 34 inches) — 2 inches wider than the US standard. Heights also differ: 2,100 mm (82.7 inches) versus the US 80 inches.
02What is the minimum door width for wheelchair access?
The ADA (Americans with Disabilities Act) requires a minimum clear width of 32 inches for accessible doorways. The UK equivalent under Part M of Building Regulations requires 775 mm (30.5 inches) clear width, though 800 mm (31.5 inches) is recommended.
03Why do door sizes vary by country?
Each country has its own building code governing minimum dimensions for safety, accessibility, and structural standards. Climate, construction traditions, and metric vs. imperial measurement systems all contribute to the differences.
04What is the standard door size in the UK?
UK interior doors are typically 762 mm (30 inches) wide by 1,981 mm (78 inches) tall under BS 4787. Exterior doors are 838 mm (33 inches) wide. These are slightly narrower and shorter than US doors.
05How tall are doors in Japan?
Many modern Japanese interior doors are about 2,000 mm tall, or 200 cm, though exact sizes vary by apartment, house, and manufacturer. Older homes and sliding doors can be shorter, so measure the actual opening before moving tall furniture.
06How do I measure a door opening for furniture delivery?
Measure the clear width (frame edge to frame edge, not the nominal door size), the clear height (floor to frame header), and the depth of the frame. The clear width is always smaller than the listed door size due to the frame and stops.
07What is the standard door size in India?
Indian residential doors follow the National Building Code of India (NBC 2016). A standard internal door is about 900 mm (35 inches) wide by 2,100 mm (83 inches) tall, the main entry door is typically 1,000 mm (39 inches) wide, and bathroom doors are around 750 mm (29.5 inches).
08What is the standard door size in China?
Under GB 50096, Chinese apartment unit-entry doors are at least 1,000 mm (39 inches) wide, bedroom and living-room doors at least 900 mm (35 inches), kitchen doors at least 800 mm (31.5 inches), and bathroom doors at least 700 mm (27.6 inches), with heights around 2,000–2,100 mm.
09Will furniture fit through a standard 32-inch door?
Most furniture fits through a 32-inch (81 cm) interior door when carried on edge. A 27-inch washer clears it easily; a queen mattress flexes through; a sofa usually fits tilted on its side. Wide refrigerators (33–36 in) are the common exception and often need the doors removed.
