Standard door width by country: interior and front doors in cm and inches (2026)

Last checked: 25 October 2026. Written by the Flatwalk team.

Short answer. There is no world standard. A UK room door is usually 762 mm (2 ft 6 in) by 1981 mm (6 ft 6 in). US and Canadian doors run from 24 to 36 in, 32 in (81 cm) often called standard, by 80 in (203 cm). Australia uses 820 × 2040 mm, and most of mainland Europe about 60 to 90 cm by 2 m. Front doors are wider: 838 mm in the UK, 36 in in the US, about 90 to 100 cm in Europe. With the door open you get 3 to 7 cm (1 to 3 in) less than the label.

The number that matters

The label can mean the leaf, the frame or the hole in the wall. What a sofa or a wheelchair gets is the clear opening, with the door open. In England an 826 mm leaf counts as 775 mm clear; a German 86 cm leaf gives about 82 cm; a French 83 cm door gives 80 cm; a Swedish 9x21 gives about 77 cm.

These are the usual sizes, not rules: old buildings and made-to-measure doors differ. Your own tape measure is the only number that counts.

Each rule measures in its own way, and some ignore the handles. A sofa does not.

Measuring your own door

Open the door fully and measure the narrowest point, from the handle if it sticks out (number 5 in the drawing). For the height, measure from the finished floor to the underside of the frame. Buying a new door for an old frame? Measure the leaf. Write it all in one unit. The door is only one point on the way in: see "Will it fit through the door?" for halls, turns and stairs.

Common mistakes

• Ordering by the label. A Polish "80" is 84.4 cm wide, a Nordic 9x21 is the hole in the wall, and a Czech "80" is the clear width.
• Measuring the leaf, not the clear opening. The open door takes 3 to 7 cm.
• Mixing systems. A 2 ft 6 in door is 76.2 cm, not 80 cm.
• Assuming the rules apply to your home. They set minimums for new or public buildings.

Check that furniture fits in 3D

In Flatwalk the tape measure lives in the 3D flat: tap both sides of a doorway and read its width, then hold a real sofa at its true size against it. Flatwalk does not test the route or your country's rules for you; measure the real doors with a tape.

Questions people ask

What is the standard interior door width in the UK? 762 mm (2 ft 6 in) by 1981 mm (6 ft 6 in) is the most typical. 838 mm (2 ft 9 in) is the wider choice, and metric doors 2040 mm tall are also sold.

Is 30 inches a standard door width? Yes. It is a standard US width, and the UK's 762 mm door is exactly 30 in. Open, it gives a few centimetres less, under the 32 in clear asked of US public buildings.

What is the standard front door width? About 36 in (91 cm) in the US, 838 mm (2 ft 9 in) in the UK, 820 mm in Australia, and about 90 to 100 cm in much of Europe.

How wide does a door need to be for a wheelchair? It depends on the country and the rule. For example: 32 in (815 mm) clear under the US ADA for public buildings, 850 mm for the front door of an accessible new home in England, and 90 cm under Germany's DIN 18040-2 for wheelchair use.

What does 9x21 mean on a door? It is a Nordic module size: a wall opening of about 900 × 2100 mm. The door leaf itself is 825 × 2040 mm.
