In order to bring the production of interior elements to a single model, standard dimensions of interior doors were introduced and approved at the state level. This greatly simplifies the selection of products when it is necessary to replace them. It is enough to make a correct measurement of the parameters of a typical opening and buy a suitable model.
If there are no problems with domestically produced products, then when buying an imported interior door, a difficult situation may arise, since there is a different standard in foreign countries. In addition, when buying alternative types of doors (double, sliding, hidden), you need to know some of their design features.
State standards
There are certain approved state standards (GOST), according to which domestic manufacturers produce interior interior elements. These are GOST 6629-88, as well as SNiPs 21-7, 21-8, 21-9, 21-10, 21-13. For ease of viewing, these data are summarized in a table, where the most common standards are displayed:
If the choice fell on a product of imported origin, then the dimensions of the interior door can be checked for compliance with European standards DIN 18100-18102, as well as DIN4172, indicating the dimensions of the opening in the light:
These dimensions must be taken into account if you plan to order, for example, an Italian door. Most likely, imported models will have non-standard dimensions that should be taken into account when laying doorways in the process of planning construction or major repairs.
For doorways in height exceeding 2000-2040 mm, its own standards have been developed, indicated in the table below.
The development of state standards takes into account the needs of the main segment of the population living in standard buildings. In the choice of typical models of one size or another, its functional purpose also plays an important role. In other words, the place in the apartment where this product will be located is important. In accordance with this requirement, the dimensions of the canvas, design features, and equipment with special fittings are selected.
The nuances of correct measurement of the opening
In some cases, it becomes necessary to independently measure the parameters for the purchase of an interior door. This happens if the house or apartment is located at a great distance from the manufacturing company, in another city or in another state. Self-measurement is also carried out in cases where there is no time to wait for the visit of the measurer, or it is more convenient for the customer to take measurements on his own. Regardless of the reason, this event must be carried out as accurately as possible so that the selected model fits perfectly into the existing opening without the need to adjust it. This means that the height, width and thickness of the interior door leaf should be as close as possible to the corresponding parameters of the opening. To carry out a correct measurement, you should be guided by the following rules.
Determination of the value of the width of the opening.
To do this, measure the distance between the walls at the narrowest point of the opening. If the wall becomes narrower closer to the door, then it is necessary to measure in this part. In the case of a uniform wall width without tapering, the location where the width is measured is not critical. If the dismantling of the old door has not yet been made, then the measured distance from the middle of one platband to the middle of the opposite platband is the width of the interior doors.
Determination of the height of the opening.
To determine the indicator of this dimension, it is required to measure the distance from the point of the finished floor to the lowest point of the upper part of the opening. If the doorway narrows closer to the hinges, then the measurement should be taken in this area. If the height of the opening is uniform, then the location of the measurement is not critical. The easiest way to measure is the old door, if it has not yet been dismantled. In this case, the height of the interior doors will be equal to the distance from the middle of the upper platband to the zero point of the finished floor.
Determination of the depth of the opening.
To do this, you will need to measure the thickness of the wall in which the doorway is located. This will be the depth of the opening. Measurement should be made in three sections: top, middle and bottom on both walls. This meticulous exercise is necessary in order to identify the widest spot in the wall. If the old door has not been dismantled, then it is necessary to measure the dimensions of the box and the wall (thickness) if it protrudes beyond the box. It is best to use the services of a professional to correctly measure the three key dimensions. Possessing a body of knowledge, the installer will make an impeccable measurement and give practical advice on choosing a typical or non-standard interior door. We remind you that when ordering doors from Porta prima, the visit of the master to measure the dimensions and consultation on the choice of the door leaf are absolutely free.
Formulas for measuring door leaf
Often there is such a situation that it is required to make a doorway, and the choice of the model of the canvas has not yet been made. In this case, to measure the parameters of the opening, the following points must be taken into account:
- dimensions of the door leaf (width, height, thickness);
- box dimensions (thickness, width);
- indicator of the width of the platbands.
For greater clarity, an example of calculating the dimensions of a doorway will be given.
Suppose that a standard size door leaf with the following dimensions will be used for installation:
- Vdv - door leaf height - 2000 mm;
- Шдв - standard width of an interior door - 70 0 mm.
With such parameters of the interior product, a box will be installed, the thickness of which (Tc) will be 30 mm. In this case, the size of the mounting gap (Mz) will be equal to 10 mm, and the value of the door block (Bd) will be 20 mm. At these standard values, the threshold height (Bp) will be 20 mm.
Formula for calculating the width of the opening of the future door:
W of the opening = Shdv + 2 × Tk + Mz + 2 × Bd = 700 + 2 × 30 + 10 + 2 × 20 = 810 mm.
The opening height is calculated using the following expression:
In the opening = Vdv + Vp + 2 × Tk = 2000 + 20 + 2 × 30 = 2080 mm.
Therefore, for an interior door leaf with dimensions of 2000 × 700 mm, it will be necessary to make a doorway of 2080 × 810 mm.
The door frame is manufactured according to the standard of the opening depth of 7.5 mm. If the thickness of the door leaf of the interior door does not correspond to this indicator, it is necessary either to order a box according to individual dimensions, or to use additional elements in the design. Therefore, it is recommended to make calculations in advance.
How to calculate if the door fits into the opening?
A common situation is when a standard door is selected to an existing opening. Usually, a good clue for choosing is the labeling of door products, on which the main dimensions are indicated.
At this stage, doubts may arise whether the product will fit and whether there will be additional difficulties in its installation.
To dispel doubts, you need to reason as follows:
- Let's say we have a doorway of 900 × 2040 mm, which meets the standard.
- We calculate the width: we add the indicator of the standard width of the canvas 800 mm with the thickness of the box (on both sides) and design intervals of 15 mm. Note that there is an interval to the left and right of the door, so you need to multiply it by two. When calculating, we get 880 mm.
- We calculate the height in a similar way. A door leaf height of 2000 mm is added to the box thickness of 25 mm and the top mounting distance of 15 mm. We get the value 2040 mm.
Therefore, an interior door with a standard size of 800 × 2000 mm will ideally fit into a typical opening with dimensions of 900 × 2040 mm. This once again proves the need to create state standards in the construction industry. You can safely buy a typical product without worrying about whether it will fit.
What to do if the door is chosen incorrectly?
However, there are situations when the purchased canvas with the box was not chosen accurately. When the return of the purchase is impossible for an objective reason, you can use some construction tricks:
- when only a few millimeters in the width or height of the doorway are missing, you can carefully cut a wider hole in the wall;
- if the box is narrower than the thickness of the wall, it is recommended to use an extension that will cover the prominent area of the thickness of the wall;
- if the thickness of the box is much narrower than the dimensions of the doorway, then along the perimeter of the box (with the exception of the bottom) they are drawn into an even slope;
- if the listed methods are unacceptable, it is recommended to order doors according to individual non-standard parameters.
At Porta prima you can buy high-quality standard interior doors or order an individual design according to your project.

A beautiful interior is not only wall, ceiling and floor decoration, but also well-chosen furniture and curtains. Do not lose sight of the fact that interior doors play an important role in the interior. It is they who sometimes emphasize everything that is conceived by the designer. Therefore, it is very important to choose the right door, not only in terms of their design, but also in terms of size. It is about them that will be discussed in this article. We will consider the standard dimensions of interior doors, their correspondence with the aisles. Correct measurement methods and calculations will be shown.
Interior doors
The main function is to close the passage between rooms. And depending on the closed premises, it can have different sizes. For example, the widest structures are installed at the entrance to the hall. The smallest in the office space.
At the same time, such a functional feature as transparency is used only for certain rooms. You can’t put them in the toilet and in, that's for sure. According to purely constructive criteria, they can be swing, sliding, folding, cassette.
There are standards for dimensions that were adopted even during the construction of the first apartment buildings in Soviet times. They have changed slightly since then. For example, the standard door height is 2 m.The Europeans have a standard of 2.1 m. Since most of the computer programs for the production of various products and the design of buildings (meaning purely constructive planning and calculation) came to Russia from European countries, then domestic manufacturers have gradually switched to this height size. Although it is impossible to say that about everyone. That is, when choosing a door, you must first measure the height of the doorway.
As for replacing old doors with new ones, if a major alteration is not planned, and simply replacement is made, then standard typical interior doors are selected. If additional openings are being constructed or made, then the dimensions of the door frame are taken from the overhaul project. It is clear that the choice of a standard model is not only a simple choice from the products offered on the market, but also a simple installation in a standard opening.
Standard dimensions of interior doors - GOST and requirements
So, there is a GOST of the dimensions of interior doors, according to which they are produced. It indicates not only these parameters, but also the size of the opening for interior doors. These two meanings are interrelated. Table of standard sizes for interior doors:
| Height, mm | Width, mm |
|---|---|
| 2000 | 550 |
| 600 | |
| 700 | |
| 800 | |
| 900 | |
| 1200 - with two sashes, 600 mm wide each | |
| 1400 - with two leaves, width of one 600, the other 800 mm. | |
| 1500 - with two leaves, the width of one is 600 to the other, 900 mm. |
If the dimensions of the door you are purchasing exactly correspond to the parameters indicated in the table, then you are very lucky. Because standard items are much cheaper than ordered items. Of course, a doorway can be fitted to a custom door, but this is not always possible. This is especially true for panel houses, in which it is impossible to expand the openings or increase their height. This violates the integrity of the entire structure of the house.
There is one more parameter that must be mentioned. This is the width of the timber from which the door frame is made. Basically, three dimensions are taken into account when planning and marking:
- clean opening is the width of the door leaf;
- door frame width;
- width of the opening in the wall.
By the way, here you can't talk only about the width. Exactly the same relationship between the height parameters. So between the outer ends of the box and the inner wall opening there should be a gap of 10 ÷ 15 mm. This is done so that the box can easily stand in the opening, and so that it could be aligned in planes.
Standard sizes of doorways
Table of standard dimensions for the height and width of the doorway in accordance with the same dimensions of the frame, which were indicated in the first table:
| Height, mm | Width, mm |
|---|---|
| 2060 ÷ 2090 | 630-650 |
| 680-700 | |
| 780-800 | |
| 880-900 | |
| 980-1000 | |
| 1280-1300 | |
| 1480-1500 | |
| 1580-1600 |
As you can see, the standard dimensions of doorways are slightly larger than the parameters of the doors.
Door frame dimensions
And one more indicator that must be taken into account is the thickness of the door frame timber, it determines the thickness. The standard size is 75 mm. It was legalized for one reason - this is the thickness of the reinforced concrete slab, which is used for the partition in old-style apartment buildings. It was this thickness that guaranteed the required load-bearing capacity of the curtain walls.
How to correctly measure the parameters of the opening
This is a very important component of the repair, because it depends on this action whether the door structure fits into the opening, and what dimensions the gaps between the mating elements will be. The thing is that the quality of construction in those early years left much to be desired. Therefore, the openings in the walls do not guarantee the evenness of the edges, both vertically and horizontally. That is, the geometry of the shape is not an exact rectangle.
Therefore, measurements must be taken in several places. Usually it is along the edges and in the middle (even in several places). In this case, all measurements are carried out strictly in planes, that is, horizontally and vertically, for which you will have to use additional control instruments such as plumb lines and. The photo below shows how to correctly measure the dimensions of the opening for an interior door with a frame.
As practice shows, the doorway very often does not correspond to standard dimensions. If the actual parameters are slightly larger, then this is not a big problem. The gap can be filled with mortar and closed with additional elements, or you can order a door with large parameters. If the dimensions are smaller than the standard, then the edges of the opening will have to be adjusted to fit them. Or fit the door under the opening.
Attention! If the width of the opening is more than 1000 mm, and the door according to the plan should be a swing door, then you will have to order a two-leaf version. Because the door leaf should not be more than 900 mm.
Why such a strict warning. It's all about the weight of the door leaf. Its hinges simply cannot withstand long-term use. After which it will just start to sag, and these are problems when closing.
And a few words about accessories for interior doors, or rather about their sizes. Even here there are standard parameters: length - 2.1 m, width - 0.7 ÷ 2.5 cm, thickness 0.6 ÷ 3 cm - this is for the strip with which part of the end of the wall is closed. But it must be noted that the width can be up to 4 cm. This is for load-bearing walls. As for the platbands, there are no standards.
Selection of the sizes of standard interior doors with a frame between the corridor and the hall
Table number one shows the dimensions of wide doors, which are designated as double doors. Above, attention was focused on why it is in these places that structures with two sashes are installed.But it must be added that standard interior doors with a frame installed in the hallway are the dimensions of typical openings. Even in those distant Soviet times, the passage to the hall was made wide, because the living room is a place where sometimes a lot of people gather. This means that the entrance to this room must be large. In addition, it is in it that dimensional furniture is installed, which may not squeeze into an opening with small dimensions. That is, they took into account both purely aesthetic criteria and purely practical ones.
Interior door marking
All wooden door structures are controlled by GOST number 6629-88. This document says that products (wood) have a graphic and letter designation. We are interested in the letters, because they are indicated in the accompanying documents.
So, what do the letters in the marking mean?
- "O" - with glazing;
- "Г" - deaf construction;
- "K" - a canvas with a swinging sash;
- "U" is a reinforced model that can be installed as an input.
At the same time, there are letter designations that relate directly to the structure. The letter "D" means that this is a door block, the letter "P" that it is just a canvas.
Attention! In the marking of interior double-leaf doors, the dimensions of the leafs must be indicated.
Sizes of non-standard interior doors
What does it mean, non-standard interior doors and what are their dimensions? That is, if a door, say, 700 mm wide, does not fit into the opening, but leaves large gaps with a width of 600 mm, then it is necessary to make a structure with parameters somewhere between these values? Will this be a non-standard model?
If "YES", then all products made to order and not falling under the GOST parameters can be considered non-standard. But let's think sensibly. The construction of apartment buildings is carried out according to projects that are themselves developed according to standards. This means that they cannot have non-standard doorways.
Then, under what circumstances are non-standard designs used? There are two options:
Variety of interior doors
Basically, all interior doors are divided into three categories, which are based on purely constructive solutions.
- Swinging, when the canvas is opened by twisting around the hinges.
- Sliding, when the canvas moves along the wall along the guides.
- Foldable, when the structure is folded like a book, opening the passage.
Swing
The most commonly used type. The conservatism of people sometimes reaches the point that swing models are installed even where they do not belong.
Sliding
These models are often referred to as compartment doors. There are two varieties that differ from each other in the openness of the canvas when opening. That is, it simply moves along the guides along the wall or is recessed into the wall itself. The second option is preferable, but difficult to install.
The disadvantages include the fact that special fittings are required for installation. And the installation process itself is not easy. Like swing doors, they can be single or double-leafed. In the second case, the doors simply move apart in different directions when they need to be opened.
Foldable
By the way, the first two options can be designated as the standard for the size of interior doors with a box. What can not be said about the folding design. It is with it that it is most convenient to block non-standard openings. The canvases in them are fastened to each other by hinges, and the movement is carried out on rollers. In this case, the number of leaves can be unlimited. Again, everything will depend on the width of the opening.
It should be noted that the minimum width of one sheet is 10 cm. That is, the less this indicator, the more sashes will have to be made for the structure. Although such models look very original.
The advantages include the ability to close curved openings. But one single drawback is quite serious. This is a loose abutment of the canvases both among themselves and to the box. So there is no tightness.

Repair is a laborious process that requires a responsible approach and due attention. A high-quality result is possible only with strict adherence to a certain order of actions. According to him, before finishing the walls and floor, you need to install. Such a structure in its finished form is an immovable box, made up of vertical and horizontal racks on which the canvas itself is subsequently attached.
When purchasing internal structures for your apartment, house or office, along with structural, functional and decorative features, you should take into account the standard ones suitable for the doorway for correct installation. In order to avoid problems and additional waste in the future.
Internal Door Construction Standards
Sizes should be standard, but, based on practice, most often they are slightly smaller or larger than stated. Today, almost all manufacturing firms produce standard canvases, and if the "hole" in the wall does not correspond to GOST, then you will have to overpay for non-standard sizes.
The parameters provided for by the requirements prescribed in the regulatory documents determine different typical values depending on the purpose of the apartment premises. The canvases, produced in accordance with the dimensions fixed in GOST, fit perfectly into the doorways of one-room apartments.
In apartments with a large number of rooms, the dimensions of the canvas at the entrance to the living room (with a double-leaf model) are 1200 wide (of two canvases, 600 or 400 + 800), 2000 - in height.
The generally accepted standard sizes that were observed during the Soviet era are absent today. They differ slightly from manufacturer to manufacturer. If we consider a single-leaf model, then the parameters of door systems fluctuate in the following range (in mm):
- height - 1900-2100;
- transverse length - 550-900;
- depth - 15-45.
In-line production basically adheres to those dimensions that are presented in GOST. exceed the width of the web by 60-70 mm.
If the size of the opening corresponds to this data, then it will be very easy to choose the appropriate model with a fairly large assortment. But if it deviates up or down, then difficulties may arise during installation and a model will need to be made to order. Thanks to modern technologies, manufacturers can produce any standard size. Only in this case, the interior system will cost much more, and along with this, you will have to spend money on installation.
In such a situation, many people prefer to fit the "door hole" to fit standard interior systems. Since the "generally accepted" option is not only cheap, but also convenient in the sense that you do not have to look for and spend money on separate parts for the box, the installation process may be limited to minor adjustments in work.
Dimensions of doorways in accordance with GOST in accordance with the typical dimensions of the canvases
Standard is an advantage when it comes to door parameters. When choosing a standard design, you do not have to ask yourself the question: how to hang other loops or expand (narrow) the place where the canvas with the box will be installed.
Entrance door standards
When it comes to steel entrance structures, it is better to experiment with design, material, shade, but certainly not with dimension. To avoid the possible modification of the walls or the case when a non-standard one is required, which will cost almost ½ times more than the standard design, it is necessary to determine the dimensions of the door leaf. After all, the size of the entrance is of great importance.
In the worst case, the installation of door systems from a simple and inexpensive labor will turn into a long and unpleasant job, especially if you install the structure yourself, without having the appropriate experience.
To determine the size, you need to measure the movable opening part of the structure and calculate the dimensions of the doorways (by measuring the transverse length, height and depth).
Standard sizes of metal doors
Table of doorways and recessed steel structures
The dimension of "wall holes", and at the same time the dimensions of iron doors, in practice, do not always coincide with GOSTs.
In addition, imported standard sizes are fundamentally different from the standards adopted in Russia.
General information
- The width of the doorway in new buildings is 740-760, and the height is in the range of 1950-1980.
- In brickwork houses, these indicators are 880-920 for width and 2050-2100 for height.
- In obsolete houses, the dimensions of openings for structures consisting of one sash can be 830-960 in width and 2040-2600 in height.
- In nine-story buildings, built in the 70s, "wall holes" are equal to 1280 * 2550.
"Wall openings" in standard houses differ in a variety of types (at the entrance, expandable, narrowing, with no niches) and dimensions. Therefore, the parameters of the steel system may differ even in the riser or in adjacent entrances.
About standard sizes
In accordance with SNiP 210197 (sanitary norms and rules on fire safety of buildings and structures), paragraph 6.9, entrance doors are an exit to evacuation. According to part 6.16. of the same document, should not be lower than 1900 m, and the transverse length should not be less:
- 1200 mm - in the case of kindergartens, hospitals, special homes for the elderly and people with disabilities, when the number of people being evacuated is 15 people and more; when it comes to structures of other classes of constructive fire hazard (except for apartment buildings), then the number of evacuees is over 60 people.
- 800 mm in other cases.
The parameters of external metal structures on landings and in the room in front of the entrance to the internal parts of buildings must have the parameters specified in paragraph 6.29.
The width of the exit leading to the escape route must be dimensioned so that an ambulance stretcher with people can be freely carried through it.
The parameters of the entrance structures are determined by state standards, but their norms do not apply to special-purpose systems and doors installed at capital construction sites. The dimension of the canvas is determined by the dimensions of the opening. Where it will be mounted according to the plan.
The standard dimensions of interior doors must be known for the correct installation of the door in the opening. So far, no general guidelines have been established for manufacturers to comply with them. But there are building standards on the basis of which openings are made. From such indicators, the characteristics of the door will be determined.
Door marking
With product labeling, everything is quite complicated. Of course, there are specific standardized guidelines for notation, but in some cases the general standards may change due to the abundance of manufacturers. It often happens that designs made using identical techniques and outwardly similar structures can be named and labeled differently.
The dimensions of the door directly depend on the dimensions of the opening
First, let's deal with the GOST 6629-88 standard, which applies to the manufacture of wooden interior doors for residential and public facilities. Based on the standard, the following labeling is applied to products:
- Product type: P - panel, D - prefabricated;
- Panel type: O - glazed, U - reinforced with continuous filling, K - swinging with glass;
- The width of the door structure with a box (dm). Additionally, the following symbols are indicated: P - product with a sill, N - overlaid, L - left-sided;
- Height (dm);
- The name of the state standard.
In addition to compliance with GOSTs, official model names, factory unique codes can be used.
Structures are classified according to several criteria:
- By placement in the facility - there are internal (interroom) and external (entrance);
- By material, products are distinguished from metal, wood, glass and combined options;
- According to the filling of the blank panel, there are glazed and blank systems;
- According to the number of panels, one-, one-and-a-half and two-field options are distinguished.
Fig. 1. Sash opening method Standard dimensions of hinged interior doors
Considering the dimensions of internal doors with a box, one should take into account the height, width and weight of the parts. First, the opening is examined into which the box with the canvas will be inserted. Therefore, the initial characteristics are slightly increased. To adjust the basic dimensions, you can use blocks, bricks or sheets of drywall.
Canvas dimensions
If you do not use non-standard approaches, where the dimensions of the opening for interior doors are tied to individual wishes, then the bulk of manufacturers is based on the indicators of the standard. The ratios of indicators of the opening and door systems (panels and boxes) based on SNiP are shown in the table:
| № | Panel indicators, cm | Opening characteristics, cm | |
| Width height | width | height | |
| 1 | 60*200 | 68-71 | 205-207 |
| 2 | 70*200 | 78-81 | 205-207 |
| 3 | 80*200 | 88-91 | 205-207 |
| 4 | 90*200 | 98-101 | 205-207 |
| 5 | 60*190 | 68-71 | 195-197 |
| 6 | 55*190 | 63-66 | 195-197 |
| 7 | 60+60*200 | 128-131 | 205-207 |
According to the DIN standard, the ratio will be as follows:
| № | Door parameters, cm | Opening characteristics, cm | |
| Width height | width | height | |
| 1 | 60*200 | 70-74 | 206-208 |
| 2 | 70*200 | 80-84 | 206-208 |
| 3 | 80*200 | 90-94 | 206-208 |
| 4 | 90*200 | 100-104 | 206-208 |
| 5 | 60+60*200 | 134-140 | 206-208 |
If we consider the parameters of any sliding and swing door, each person provides for the width that he will use every day. But the state standard offers a door width of 70 cm for kitchens, 60 cm for bathrooms and 80 cm for residential buildings.On the market, they offer designs for a bedroom with a width of 90 cm, and for bathrooms - 55 cm.
Rice. 2. Characteristics of the canvas for rooms It is worth mentioning the double-leaf structures that allow you to emphasize the status of any room. Basically, they consist of the same type (60 cm each) or different canvases (60 and 80 cm wide). Of the narrowed options, manufacturers offer designs with sash widths of 40 and 80 or 40 and 40 centimeters.
The more common width of the canvases is 35 - 40 cm, but the indicator can change up or down (based on the material used and the type of product). For example, the thickness of a sliding sash can be 2 cm, and wooden canvases can be up to 50 cm.
In terms of height, manufacturers offer products of 190 and 200 cm, but there are also European standards - 210 cm. On order, customers can purchase products of a higher height (up to the ceiling or 2.3 m). Designers often adhere to foreign standards.
Rice. 3. Main characteristics of doors
Box dimensions
There are ready-made options for sale (with a box and fittings). This is a U-shaped structure, which is placed along the perimeter of the opening. The system allows you to securely fix the panel.
The total height and width of the web with the box increases by 10-15 cm, but a gap should be left between the wall and the mounting strip, therefore, the parameters of the web should be less than the characteristics of the frame (to protect against abrasion). The thickness of the panel is compared with the size of the wall and the box. Correctly mounted doors will be comfortable, look organic in the room, and meet the applicable standards.
Based on the characteristics of the panel, for interior structures, the indicators of the standard dimensions of the door frame of the interior door may differ. Therefore, it is advisable to purchase the designs together with cashing, frame and fittings.
Bars of different parameters are used for the manufacture of the box. The width of the material can reach 1.5-4.0 cm, but the optimal indicator is 3.0-3.5 cm. If the standards are observed, a reliable design is obtained that lasts a long time.
Rice. 4. Dimensions of the door frame The thickness of the box and the wall should be the same, but this indicator should not exceed the width of the opening. For wooden walls, the criterion is 10 cm, and for brick - 7.5 cm. Therefore, the box, the dimensions of which exceed the parameters of the wall, cannot be firmly fixed. Otherwise, special extensions can be used.
When manually assembling the box, it is necessary to determine the parameters of the vertical racks in accordance with the height of the panel, the thickness of the horizontal strip, the dimensions of the gap and the threshold. The parameters of the horizontal plank are calculated according to the width of the door.
Sizes of openings
When creating partitions and walls, you can determine the width of the opening according to the standard, which indicates the parameters of products with a frame and fittings. In this case, the width of the panel is folded with a double frame indicator and a double-sided gap. As a rule, it is equal to 1.5 cm.For example, 90.0 + 3.0 * 2 + 1.5 * 2 = 99.0 cm.
The height of the opening is also calculated: without a sill, it will be equal to 200 + 3 + 1.5 + 0.5 = 205 (0.5 is the distance between the panel and the floor for air exchange, it can increase up to 1 cm, and for a house with liquefied gas - up to 1.5-2 cm). In the presence of a threshold, the height of the opening is determined by adding the size of the opening and the parameters of the canvas, the width of the assembly seam and the box.
Rice. 5. Measurement of openings The thicker the canvas, the better?
Thick canvases well emphasize the design of the living room, made in the Baroque, Renaissance or Empire style, and sliding partitions and thin screens will complement the openings of dressing rooms and storage rooms. With an increase in the thickness of the door, its weight increases, which increases the requirements for hinged fittings. It may be necessary to install additional hinges, which will increase the cost of the structure... Therefore, the canvas should be selected for its massiveness and other characteristics according to expediency, optimality.
There are many products on the market with a leaf thickness of 30-40 cm. But the assortment includes thinner sliding partitions made of MDF (about 2 cm). Recently, designs made of tempered glass with a thickness of 8 mm or more have become popular.
One-and-a-half and double-leaf doors
Double swing doors with two leaves will look effective in design. The width of the products depends on the model and parameters of the living room passage. Parameters for such doors are sometimes accepted with an increase of 1.5-2.
Standard dimensions for double systems with a box are 120-150 cm. This allows the installation of full-fledged double-leaf structures. The width of double-leaf doors is 1-1.4 m.
At minimum dimensions, double doors can be offered with one fixed leaf width of ½ or 1/3 of the standard width (eg one-and-a-half versions). Another part of the canvas will be complete. With the optimal opening width, identical sashes are placed, which increases the aesthetics and maneuverability.
Doors with a hidden frame
Compared to standard designs, doors with an inner frame have great advantages.
Fig. 6. Scheme of a door with a hidden box The dimensions of the opening must comply with the standards of the manufacturer of door systems: there must be an even wall vertically, a deviation of 1 mm is allowed in height, and the thickness of the walls must not be more than 8 cm... The ideal gap width is 1.7-2 cm ± 1 cm (the gap in the lower part of the web 4 is considered optimal).
Doors to order
The factories offer a wide range of interior doors with a frame and fittings, including non-standard options. But there are cases of inconsistency of the manufactured products with the existing opening. At the same time, you can adjust it by increasing or decreasing the height and width to the required value. An alternative solution is to order a design with non-standard dimensions.
The cost of manufacturing custom-made doors will be higher in comparison with the purchase of finished products. But this will allow you to implement interesting ideas. For example, you can put compartment doors.
How to measure the opening
If the door has a sill, the length of the opening can be calculated by summing the height of the threshold with the parameters of the panel, frame and assembly seam.

Fig. 8. Determination of indicators with and without a nut According to the standards, it is not difficult to know the width of the panel. For a 90-centimeter opening, a canvas 80 cm wide is suitable. This can be calculated as follows: 90-15 * 2-30 * 2 = 81 cm, and the extra centimeters will be masked by platbands.
When determining the dimensions, it is better to take into account the gap that will remain between the panel and the box. But this indicator is equal to 1-2 millimeters, therefore, in approximate calculations, it can be disregarded.
When buying interior doors, first of all, you should pay attention to their size. The correct choice will allow you to reduce the cost of preparing the opening and easily install the frame and canvas yourself.
Standard sizes of interior doors
The easiest way is to choose doors for the rooms of apartments in old houses. In Soviet times, high-rise buildings were built according to standard designs, and the dimensions of the openings in all rooms were regulated by GOST. Doors sold today in specialized stores are also usually standard and have dimensions ideally suited for apartments in block houses and Khrushchevs.
What dimensions have openings and door leaves in old high-rise buildings, you can see below. The table shows the standard dimensions of interior doors with a frame.
The standard dimensions of the doorways of interior doors in width, thus, can be 60-90 cm. Their height is always the same - 2 meters.
Modern doors
In new multi-storey buildings, as well as in cottages, interior openings can be of a variety of sizes. Any standards in this regard are not observed in our time. However, it very often happens that doors of standard dimensions are suitable for atypical rooms. For example, a canvas made in accordance with GOST 21-8 is often an ideal option for opening a bathroom or a bathroom, and a wide opening 21-9 or 21-10 can lead to the kitchen, depending on the layout.
Where to get doors for non-standard openings
First of all, the owners of atypical apartments and country houses, who decide to change the doors, should, of course, measure the openings. If it turns out that the standard dimensions of interior doors do not correspond to them, you should nevertheless first visit several specialized stores. Perhaps it will be possible to select suitable designs. If not, the doors will have to be ordered from a company specializing in their manufacture. The list of services of such firms usually includes accurate measurements of openings, fabrication of structures from scratch and their installation. Of course, the change of canvases and boxes will cost much more in this case.
How not to be mistaken with a choice
In order to avoid unnecessary costs when replacing the canvas, of course, you should know not only what the dimensions of the standard opening of the interior door have, but also what are the correspondences of the dimensions of atypical blocks and passages. Which doors will be most suitable in the latter case, you can see in the tables below.

What can be the thickness of the door
The standard dimensions of interior doors with a frame, therefore, correspond to the openings of typical apartments. If desired, today you can choose suitable designs for rooms with an unusual layout. Well, or as a last resort, order. The thickness of modern door frames can also vary. Most often, interior doors of 35 and 40 mm are sold in specialized stores. Sometimes you can also find models at 36 and 38 mm. Natural wood canvases are usually 40 mm thick. However, companies specializing in the manufacture of interior and exterior doors in most cases also provide customers with such a service as the manufacture of very thick canvases of 50 cm from natural material.
Of course, you should also pay attention to the thickness when buying. This parameter determines the characteristics of the door, such as:
The amount of noise reduction. The thicker the canvas, the better it stops sounds.
Strength of the canvas.
Appearance. Thick models look, of course, more solid than thin ones.
How to measure the opening
Thus, you now know what the standard sizes of interior doors are. In general, making measurements in typical apartments is not too difficult (as well as in non-standard apartments). However, when performing this operation, you should still adhere to certain rules:
When making measurements in length and width, you need to take into account possible changes in dimensions. For example, the thickness of the future floor covering, if necessary - ceiling decoration, etc. You should be very careful when measuring, including the standard doorway of the interior door. Dimensions for various reasons (errors during construction, redevelopment, etc.) may differ from typical ones.
Before going to the store, it is advisable to measure the old door as well.
The thickness of the wall in the opening is measured taking into account the finish (gypsum board, plastic panels, etc.). If this parameter exceeds 10 cm, you must additionally buy or order a special additional element.
Also, before buying a door, you should decide on the need to install a sill. This element is usually used if the floor in rooms separated by a door is at different levels.
Thus, modern doors can be of different designs and sizes. The main thing when choosing them is to make accurate measurements of the openings. What non-standard and standard sizes of interior doors can be, we have figured out all the details. Blocks for apartments in old buildings can be purchased without any problems. Doors for atypical openings will most likely have to be ordered from a company specializing in their manufacture.
