Short answer. There is no world standard. A UK front door is usually 838 × 1981 mm (2 ft 9 in × 6 ft 6 in) or 813 × 2032 mm (2 ft 8 in × 6 ft 8 in). In the US it is 36 × 80 in (91 × 203 cm), in Canada 32 or 36 in by 80 in, and in Australia 820 to 1020 mm by 2040 mm. In most of Europe a front door is about 90 to 100 cm wide and 2 to 2.15 m high. With the door open you get several centimetres less than the label: an English 826 mm door counts as 775 mm clear.

The gap that counts
A front door size can mean the leaf, the frame or the hole in the wall. On moving day only one number matters: the clear opening, from the face of the open door to the frame on the other side. A Swedish 10x21 door has a 925 mm leaf but gives 835 mm with the door open at 90 degrees.
Flats and houses differ. A house door opens to the street; a flat's front door opens to a shared stairwell, and the building's own entrance, stairs and lift come first. Check those too: see Will it fit through the door?.

| Canada | 32 in (813 mm); 36 in (914 mm) where access matters; 30 in (762 mm) narrow | 80 in (2032 mm) | The slab. The rough opening is about 2 in (5 cm) wider and taller |

| Poland | At least 90 cm (35.4 in); 100 cm (39.4 in) is more popular for houses | Usually 200 cm (78.7 in) | Often the gap inside the frame; check the maker's table |
| Netherlands | 73 to 93 cm in 5 cm steps (28.7 to 36.6 in) | 201.5, 211.5 or 231.5 cm | The leaf, ordered by the size of the frame's rebate |
| France | 90 cm (35.4 in) | 215 cm (84.6 in) | The door, as sold |
| Spain | Security doors: leaf 82.5 cm (32.5 in), about 87 cm with the frame | 203 cm (79.9 in), about 206 cm with the frame; 210 cm in some models | The leaf, or the whole door with its frame |

| Norway | 10x21 is the most common, 9x21 fairly common | Leaf 2033 mm (80 in) | The module, as in Sweden |
| Croatia and Serbia | No standard size; doors people ask makers for are mostly about 90 to 105 cm (35.4 to 41.3 in) | About 200 to 210 cm (78.7 to 82.7 in) | Sizes in buyers' requests to door makers |
| Lithuania | 890 to 1000 mm (35 to 39.4 in) listed in a big DIY chain | 2063 to 2100 mm (81.2 to 82.7 in) | As listed by the shop |
| Japan | One maker's house door: leaf 922 mm (36.3 in), frame 970 mm | Leaf 2320 mm, frame 2373 mm; most new front doors are 200 to 240 cm | Sold by frame size; that door gives 900 mm (35.4 in) clear |
These are the usual sizes, not rules. Old houses and made-to-measure doors differ, and your tape measure is the only number that counts.
Flat front doors
A flat's door is often narrower than a house door, and it is the one the removal team meets after the stairs or the lift.
| Country | Flat front door |
|---|---|
| UK (England) | New flats: at least 775 mm (30.5 in) clear, the same as a house |
| US | New apartment buildings covered by the Fair Housing Act: 32 in (81 cm) nominal clear; a 32 in door is not enough to give it |
| Poland | At least 90 × 200 cm (35.4 × 78.7 in) |
| Serbia | At least 90 cm (35.4 in) clear and 200 cm (78.7 in) high in new flats |
| Lithuania | Flat doors in a big DIY chain: 895 × 2063 mm or 1000 × 2072 mm |
| Japan | One maker prices its replacement flat door at 776 × 1911 mm (30.6 × 75.2 in) |

| Serbia | Rules for designing homes, 2012 to 2015 | New blocks of flats | Building entrance 120 cm; flat entrance 90 cm, 200 cm high |
Each rule measures in its own way. A sofa does not care which.
What fits through a front door
An item passes a door if its two smallest sizes fit the clear opening and the height. Here is what some real doors give with the door open:
| Door | Leaf | Clear with the door open |
|---|---|---|
| England, standard leaf | 826 mm (32.5 in) | Counts as 775 mm (30.5 in) |
| Sweden or Norway, 9x21 | 825 mm (32.5 in) | 735 mm (28.9 in) |
| Sweden or Norway, 10x21 | 925 mm (36.4 in) | 835 mm (32.9 in) |
| France, new house rule | At least 90 cm (35.4 in) | At least 83 cm (32.7 in) |
| Japan, one maker's house door | 922 mm (36.3 in) | 900 mm (35.4 in) |
A standard fridge-freezer, about 60 to 65 cm (24 to 26 in) deep, goes through all of these. An American-style one is about 70 to 75 cm (28 to 30 in) deep, so a 735 mm gap is tight: take the doors and handles off. An upright piano, about 60 cm (24 in) deep, goes through upright, but it weighs 200 kg (440 lb) or more. A mattress goes through on its edge. For a sofa, compare its depth or height, the smaller one, with the gap.
If it is close, lift the inner door off its hinges or order the piece flat-packed. Then check the hall and the turn behind the front door, which is often narrower.
Measuring your front door
Open the door fully and measure from the face of the open door to the stop on the other side, at the narrowest point. Include the handle if it sticks out. For the height, measure from the threshold to the underside of the frame.
Replacing a door? Measure the leaf (height, width and thickness) or the outer frame, whichever the maker sells by, and leave a few millimetres around the frame. Write it all in one unit. The door is only one point on the way in: halls, stairs and lifts are in Will it fit through the door?, and room doors in Standard door width by country.
Common mistakes
- Ordering by the label. A Nordic 10x21 is the hole in the wall, a German front door is often sold by the outer frame, and a Polish width is the gap inside the frame.
- Measuring the leaf, not the gap. The open door, hinges and stop take several centimetres: a 32 in US door does not give 32 in.
- Forgetting the flat's way in. The building's front door, the stairwell and the lift come before your own door.
- Assuming the rules apply to your home. They set minimums for new homes. An older flat can be narrower.
Check that furniture fits in 3D
In Flatwalk you measure any wall, gap or piece with the tape, and furniture from real shops stands at its true size. Walk from your front door to the room at eye height and see where a sofa has to turn. Flatwalk does not check your stairs, lift, building entrance or your country's rules; measure the real doors with a tape.
