Standard Dimensions of Interior Doors - Height, Width, Thickness

Standard dimensions of interior doors are not always observed. Therefore, the old standards were revised and proposed new ones.

Normated standards

Despite the fact that today there are no clear requirements for the dimensions of the doorways, since construction of individual projects is very common, the question of which the size of the interior doors are, is quite often set. This is due to the desire to get such a layout of the room to minimize the costs of financial and temporary resources for the subsequent installation of constructs. Interior doors of non-standard sizes today are not a problem. However, the manufacture of the product under the order is always more expensive and takes a lot of time.

During the construction, several approved doorway sizes have always been used. Mainly it concerned the widespread panel house building. First, consider the approved product dimensions that were generally accepted, and most of them apply today.

Width, mm.	Height, mm.
Sash	Opening	Sash	Opening
550.	630-650	2000.	2060-2090.
600.	680-700	2000.	2060-2090.
700.	780-800	2000.	2060-2090.
800.	880-900	2000.	2060-2090.
900.	980-1000	2000.	2060-2090.
Typical two-dimensional blocks - the total size of two canvases
1200.	1280-1300	2000.	2060-2090.
1400.	1480-1500	2000.	2060-2090.
1600.	1680-1700.	2000.	2060-2090.

The dimensions of the doorway are selected, based on the brushed bridge. There may be a different thickness of both the bar and the entire box. It is usually given to a tolerance of about 100 mm on both indicators.

If you are chosen for the installation of the necessary dimensions for the toilet or bathroom, it is necessary to take into account that the calculation will use another size - affects the height of the threshold, which is a mandatory part of such passages.

Some options for installing boxes may include shuffle. Then almost the entire thickness of the threshold is not taken into account - it will be mounted almost flush with the floor surface.

For the opening there is a later document that has normalized the production of boxes and cloths, mainly intended for interior passes. Another grid was taken into account, in particular, a large height of the ceilings, where bivalve blocks were installed. Size table as follows:

Width, mm.	Height, mm.
Sash	Box	Sash	Box
600.	670.	2000.	2071.
700.	770.	2000.	2071.
800.	870.	2000.	2071.
900.	970.	2000.	2071.
1100.	1170.	2000.	2071.
Typical two-dimensional blocks - the total size of two canvases
1200.	1272 (1298)	2000.	2071.
1400.	1472 (1498)	2300.	2371.
1800.	1871 (1898)	2300.	2371.

As you can see, most of the dimensions of constructs correspond to the previous standard grid. The purpose of this document is to normalize the thickness of the box with gaps, the restriction is intended for production and workshops.

Modern realities

Despite the requirements, there is a big difference between documents and the actual position of things. In existing houses, another overall height is often found, as well as the thickness of the door block box. Let us give a brief description of the sizes that are found inside modern buildings.

The most common (in mm):

• 1900x550, 600 (bathrooms, kitchen, pantry);
• 2000x300, 350, 400, 450 (double-tight narrow - width of the sash, including passages between rooms);
• 2000x600, 700, 800, 900 - interroom.

Houses of Project 2P-44 (16-storey buildings) There are such door constructs (in mm):

• 1900x600 for bathroom and office premises;
• 2000x700 (kitchen), 800 (rooms), 1200 (600 + 600) (bivalve between rooms).

Panel buildings, residential buildings in 5 and 9 floors: all constructs height 2000, Width 600 Width for bathrooms, 700 for kitchen and 800 mm between rooms.

Employment of the opening in "Stalinka"

Buildings with high ceilings (Stalin's houses and buildings with a sizer between overlapping 3000, 3100, 3150 mm): height - 2300, width 650 for bathrooms, 750 for kitchen, 850 - between rooms, double swollen - each sash 750.

Really big changes are found where it is used by the opening for two-dimensional blocks. Even with a tough approach, the Soviet era of the Stalinist building includes the widest set of options. Various height, total dimensions, even the thickness of the bar, from which the flaps and the box are made - all this takes place. The dimensions are correct for about 75% of cases of other structures.

Standard recommendations

When designing construction, individual housing, large-scale repairs with reconstruction will be useful to know how it is recommended to choose the parameters of the doorway. Height, width of the opening should obey some rules. And the thickness of the box is often unimportant, and depends on the complexity of the canvas or material of the walls.

The width of the passages between the rooms should be less than that of the entrance to the room. The requirement is not mandatory, but desirable, since the input block takes into account the break of all household appliances, furniture, and also takes into account the evacuation when several people should take place at the same time.

For the input area, the minimum width recommended for the canvas is 800 mm. Such a passage will be convenient for the movement of visitors and brought large things. If possible, it is better to increase the dimension. The width of the door leaf for installation should be selected, based on the range of 850-1000 mm.

Interior passes are not intended for the simultaneous movement of several people. However, emergency cases should be provided. Therefore, for service, sanitary facilities (storerooms, kitchen, bath, toilet) The recommended envelope is 600 mm. Passages between rooms are better to increase to the possibility of carrying large things or furniture items. The width of the web for this case is selected in sizes of 700-900 mm (depends on the dimensions of the input flap for an apartment or at home).

In the bathrooms of lower widths

Although the bathroom doors, toilet, the kitchen fulfill the function of protection against moisture and foreign smells, you need to consider the dimensions of modern equipment, especially refrigerators. Therefore, modern housing construction often leaves the recommended dimensions and provides for the door leaf, whose width is often more than 800 mm. Although it is unreasonable, but it's easier, moreover, a set of constructs is simplified.

The recommended box thickness (interroom opening) is 7.5 cm. This is a kind of architectural standard. The thickness of the walls of most buildings corresponds to this size either makes it possible to mount constructs in the opening with minimal efforts. If it is planned to build plasterboard partitions, you need to or order separately boxes, the thickness of which will match the wall, or build a partition where the opening will be.

At the case where the wall thickness is much larger than the thickness of the interroom door, uses the good items. If the installation is needed under such conditions, it is better to order doors built using telescopic platbands.

The height of the doorway is a sizzy, not undergoing significant changes. Therefore, construction according to individual projects rarely departs from the above normalized indicators, although bivalve doors can have any dimensions.

Manufacturers of modern interior doors as a whole try to produce products corresponding to the dimensional grid in the last table. Therefore, to reduce financial expenses, plan the construction of walls and partitions accordingly.

In the case when the openings in the room do not comply with the standards, from the standpoint of savings, it is better to resort to fitting sizes to standardized. This will allow you to purchase the doors in the shortest possible time and install them on planned places.
