Measurement of new doors. How to measure the doorway for a high-quality installation of an interior door? Standard dimensions of entrance doors with a frame

Entrance doors are of great variety. On sale there are standard and non-standard models. In order to choose the right door block that matches the original doorway, you need to clearly understand the installation technology and the procedure. And also know the rules of installation entrance doors.

Overall dimensions of entrance doors

The specificity of the entrance doors is that they are subject to increased requirements. The main ones are strength, reliability and durability. To solve these problems, there are many tricks and constructive nuances. The door leaf is installed from metal or wood species such as oak and hornbeam. Strengthen the design of the door frame, install locks and hinges of increased anti-burglary resistance. In addition, the front door serves as the main portal for moving furniture, household utensils and, in fact, people. Its dimensions are always assumed to be larger than those of interior doors.

The metal-plastic front door is reinforced with additional hinges and armored glass

When selecting, they are guided primarily by the size of the doorway, the size of which is laid down at the design stage. If the dimensions of the opening do not suit you, during redevelopment it is increased or decreased, bringing it into line with the desired size of the doors.

Practice has shown that the most acceptable type of entry for entry is a hinged type of door. Unlike sliding or, for example, retractable, this design is less exposed to external influences, has good thermal insulation and noise reduction.

When installing, choose which way the door opens. If the opening is carried out to the outside, the space inside the hallway is saved. Knocking out such a door is more difficult, since the canvas rests rigidly on the supporting surface of the door frame.

Doors that open counterclockwise are called "right", clockwise - "left"

On the other hand, in accordance with the rules fire safety, it is recommended to open the front door inward - this allows rescuers to quickly enter the building in extreme situation and help residents.

Standard dimensions of entrance doors

With a huge variety of entrance doors, manufacturers adhere to certain standards specified in SNiP and produce finished goods the following sizes:

  1. Width. Varies in the range from 850 to 910 mm. It is possible to increase up to 1010 mm with a single-leaf design, 1300-1500 mm for one-and-a-half and 1900-1950 for double-leaf doors.
  2. Height. Can be from 2000 to 2300 mm. The exact size is adjusted depending on the position of the ceiling above the floor and in relation to the width of the door leaf.
  3. Thickness. This parameter of the door leaf is not strictly regulated. However, it must be borne in mind that the sash must withstand both mechanical loads and temperature and humidity changes. Usually the thickness wooden door(panel or panel) starts from 50 mm and above. Metal doors are made from sheet steel with a thickness of 2 mm. Metal-plastic sashes have a cross section of 50–75 mm, depending on the number of profile chambers (or double-glazed windows, if any).

The door block has several sizes: along the opening, along the door frame and along the door leaf

Entrance door frame dimensions

In most cases, the front door is sold complete with a door frame. The accompanying documents indicate the overall dimensions of the unit. In the event that the equipment is carried out independently, when calculating the dimensions of the door leaf, the dimensions of the door frame are added. In this case, it must be taken into account that between the sash and the frame there should be a mounting gap of 2.5-4 mm.

As a rule, ready-made door frames are sold under a certain standard of leaf (or two sheets in a double-leaf version). If there is a need for preliminary measurements, then the door frame is measured along the surface of the junction with the wall hole.

It is necessary to measure the external dimensions of the frame without taking into account the platbands

picking up door frame for entrance doors, you need to remember that the door leaf in the closed position rests on a rubber or silicone seal. The frame design must include a special mounting slot for the seal. This is necessary to seal the doorway and soften the blows of the canvas on the support bar.

Standard dimensions of entrance doors with a frame

For ease of selection and clarity, simple tables are used.

Table: correspondence between the dimensions of the door block and the doorway

Please note that when installing door block it is necessary to maintain technological gaps along the perimeter of the opening in the amount of 15–25 mm. This is due assembly rules. The gaps are used not only for filling with heat-insulating materials, but also for leveling the structure in the vertical and horizontal planes.

The insulation between the wall and the door block eliminates thermal bridges through which cold penetrates into the building. Usually it is polyurethane foam or mineral wool.

Technological gaps between the leaf and the frame are necessary for the free movement of the sash

Dimensions of the opening under the front door

The term " doorway” is used to describe a rectangular space allocated for the installation of a door unit. It includes three dimensions:

  • width (in the horizontal plane);
  • height (in the vertical plane);
  • depth (thickness of the wall or partition of the building).

These parameters are measured in the metric system of measures, which is now recognized as universal. The units of measurement are millimeters or centimeters. Professionals prefer to work with millimeters, as this achieves the necessary measurement accuracy.

Standard sizes doorway (width*height, mm):

  • 880*2080;
  • 920*2100;
  • 1000*2100;
  • 1270*2100.

The total width of the doorway is the sum of the width of the door block plus technological clearances

Measuring the dimensions of the doorway is carried out using a tape measure. A sketch is drawn on a piece of paper, onto which all the dimensions of the hole in the wall are sequentially transferred. It is necessary to note the height of the side surfaces, the width of the upper crossbar, the width of the threshold and the thickness of the wall. The opening is not always strictly rectangular, so it is necessary to indicate the exact dimensions of each face of the wall on the drawing. This is especially important if the door is made according to an individual project.

The drawing is made on a piece of paper with dimensions in millimeters.

Even 100 years ago, along with the metric system of measures, there were Russian and English measured systems. In English, inches and feet were used, in Russian - spans, cubits and arshins. Today, the span system is being revived in private construction. It is believed that a house built with reference to the "size" of a particular person has a positive effect on the energy of the tenant.

Pyadeva system of measures allows you to build houses for a specific person

If the opening is smaller than the dimensions of the installed door, it is expanded taking into account the required clearances. stone walls cut with a grinder or a wall chaser, wooden ones with an electric jigsaw or chainsaw. Too large openings are increased to the specified dimensions. AT wooden walls install additional bars. Stone ones are reported with bricks or building blocks.

When reducing the opening, follow the general construction rules for plastering walls

It is widely practiced to fit the opening under the right dimensions with the help of additional sashes (in width) or transoms (in height).

The transom above the door is used to decorate and additional lighting the hallway.

How to correctly measure the front door

If an old door is installed in the opening, it must first be dismantled. But since it is impossible to leave a house or apartment without an entrance door, then on preparatory stage it is enough to remove the platbands (if any). After access to the wall opens, you can measure the height and width of the doorway. It is not always possible to accurately measure the depth, however, for the manufacture of metal or plastic doors the depth of the opening does not matter. Only when installing a wooden door frame (which happens infrequently), the depth of the doorway is taken into account. In extreme cases, a frame with extensions is used, which is adjusted to the desired depth of the door opening.

Before you properly measure, you need to stock up on the following:

  • tape measure;
  • paper for recording dimensions;
  • pencil or ballpoint pen;
  • chisel.

Brief instructions for measuring the opening:

  1. The work on measuring the opening usually begins with the removal of platbands. They can be removed by squeezing them out of the door frame with a chisel. If after that the boundaries of the doorway are not visible, then the wallpaper and plaster at the measurement points are removed with a chisel.
  2. The size of the opening may vary depending on the location of the measurement. Therefore, the width is measured in three places. Two measurements are made at a distance of approximately 20 cm from the top and bottom of the door and one in the middle.
  3. Vertical measurement is done in two places. At the same time, attention is paid to the presence of a threshold. If there is no threshold, then the size from the top surface to the floor is taken into account.

Disassembly old door made in reverse order of assembly

It should not be forgotten that the vast majority of entrance doors are equipped with a threshold. Therefore, measurements of the width must be made both at the top of the opening and at the bottom. This will eliminate errors when installing the door block. The height is measured at all corners of the rectangular hole in the wall.

Metal threshold protects the door from burglary

If, after dismantling the old door, plaster crumbles in the opening or the carrier falls out wooden beam before proceeding with measurements of the dimensions under new door it is necessary to strengthen the opening. Dilapidated plaster is beaten off, and wooden details fixed firmly to the wall. This must be done carefully, since the ends of the opening serve as the main support for the door frame. Next, measure the dimensions of the opening as described above.

When choosing a ready-made door block, which includes a door leaf with a frame, you need to compare its dimensions with the dimensions of the hole in the wall. The linear dimensions of the sidewalls and crossbars should not exceed the dimensions of the doorway. Ideally, a small gap of 15–25 mm should remain around the entire perimeter (with the exception of the threshold, which is installed directly on the floor).

Scheme for measuring the dimensions of the door, where W is the width, D is the height of the door

You can measure the dimensions of the door block yourself, using a tape measure. Or refer to the technical documentation, which shows all the dimensions of the product. Each manufacturer supplies the doors with a detailed data sheet, which also describes the equipment and installation features during installation.

Gaps allow you to align the door frame in a vertical plane

If the assembly of entrance doors is carried out from prefabricated parts - the canvas and the door frame are purchased separately, then the selection of the box is based on the dimensions of its outer edges. It is necessary to choose such a door frame, the outer edges of which "fit" into the doorway with the above technological gap.

Video: installing the front door

Installing and replacing the front door is a responsible business. From right choice type of doors and installation depends on the duration of operation, reliability and appearance entrance to the building. Turning to experienced professionals, you will spend more money, but you will get guarantees that are worth it.

If there is a need to replace the entrance or interior door, you must first measure the doors. It includes measurements of the dimensions of the opening, such as height, width and depth, taking into account all irregularities. Measurement work is carried out independently or by calling a specialist at home.

The size of the opening is necessary for the correct selection entrance group. Most manufacturers produce products according to standards with small deviations in size. At the same time, even within the same building, slight differences in the size of the opening are allowed. Therefore, work on measuring the passage must be carried out before buying and installing the canvas.

Self-measurement has the following advantages:

  • do not have to wait for a specialist;
  • the exact size will be known.

Also during the measurement, you can notice irregularities that must be taken into account during installation.

Required Tools

Since you need to accurately measure the front door for installation, it is worth preparing everything in advance necessary tools. Measurements are taken with a regular tape measure. Finding minor deviations of angles is carried out by a building level or a special plumb line. Professional measurement is carried out using a laser level.

What to consider when measuring

Correct passage measurements are carried out to determine a number of indicators. It is advisable to write them in a strict order.

To measure correctly, you need to determine the following values:

  • opening width;
  • opening height;
  • depth;
  • angle (thus the distortions are measured);
  • the presence of irregularities;

Width

Taking measurements begins with measuring the width between the walls. You can do it yourself without much difficulty. Most often, standard aisles have a width of 80 cm interior doors and up to 100 cm - at the entrance.

To measure, you will need to place the tape measure at the lower level at one of the edges and hold it to the opposite wall. Then you need to start extra dimensions. It is necessary to measure the distance between the walls at the level top floor and in the middle of the opening. Measurements are taken exclusively with a tape measure. The final value is the minimum value.

The dimensions of the box differ from the width of the opening. It should be borne in mind that the size of the box is approximately 2-4 cm, so the canvas must be purchased slightly smaller. This is necessary for technological gaps during installation. In addition, the width of the box is slightly larger than the dimensions of the sash. It is necessary to provide slight gaps along the edges for free movement of the sash.

Height

After determining the width, the height of the doorway is measured. Approximate value standard designs equal to 210 cm. The measurement is carried out with a tape measure from the floor to the upper floor. Similarly to the width, measurements are taken from three sides. The greatest attention is paid to the measurement of the central part. Minimum value is the main indicator in measurements. Taking measurements on your own and alone can be inconvenient.

The installation of the interior door is carried out after the installation of the coating on the floor. This option does not require additional calculations in measurements or reduction in the size of the web during installation.

opening depth

The standard entrance structure has a depth of 7 cm. If the installation wall is different large sizes, then the part remaining after installation is closed with additional additional strips. Standard sizes can be different - they start from 10 cm in increments of 5.

When narrowing the wall to the top or bottom, the largest of the measured distances is taken into account. This is necessary for the correct selection of the additional bar. With a significant wall depth (more than 26 cm), instead of extensions, a door frame with slopes is installed.

Opening irregularities

In the measurement process, it is worth determining the parameters involved in the alignment of the opening. This is necessary to simplify installation and increase the life of the installed structure.

First of all, the vertical part of the opening is measured. This is done with a building level or plumb line. Then the diagonal is measured. A tape measure measures the length from the top corner of one side to the bottom opposite. A similar operation is performed with the other part. These values ​​need to be compared. A significant difference between them can interfere during installation.

How to correctly measure the front door

To do this, you will need to follow the following recommendations:

  1. With a tape measure, you need to take measurements from the height and width of the passage at several levels. At different points, the parameters may vary, so the dimensions are measured on top point, at floor level and in the center.
  2. Part of the openings narrows or expands to the ceiling. This feature must be taken into account. The walls can be deflected in height, so when taking measurements, it is better to use a special plumb line or a laser level.
  3. Width and height are measured outside and inside the room. If there is no floor at home or in the office, it is better to postpone taking measurements. In the process, you will need to get rid of thresholds that distort indicators.
  4. Regular dimensions steel doors 80-90 cm by 207-230 cm. The dimensions of the box for installation should be slightly smaller. This is necessary to be able to adjust the unit during installation. The gaps between the box and the opening are filled with mounting foam. But with a significant difference between the dimensions, resistance to burglary suffers.
  5. How to measure correctly metal door, not everyone knows. When replacing old design, taking measurements is carried out only after the complete dismantling of the box, threshold and trim.
  6. Measurement of the depth of the passage where the door frame is installed is made with a caliper. In its absence, two rulers can be used. It is necessary to attach them strictly vertically to each of the walls and measure the distance between them.

How to properly measure the opening for installing a new door

When sizing, there are a number of subtleties. How to properly measure interior doors:

  1. Determine the height and width of the opening, taking into account possible changes in the future (laying tiles or laminate before installation).
  2. When replacing an old canvas with a new one, you will need to find out the dimensions of the old one, as well as the depth of the box or wall without additional panels or platbands.
  3. In measuring the depth of the passage, it is taken into account greatest thickness walls.
  4. When measuring the thickness, it is necessary to take into account the work on finishing the wall.
  5. If thickness interior partition exceeds 10 cm, then the installation of additional trims will be required.
  6. For convenience, you will need to decide on the external or internal opening of the door, choose the side of the hinges.

Measurements are carried out during repairs to replace old structures. For measurements, you will need a tape measure, a building level or a plumb line. Before starting work, it is worth clearing the passage from what will interfere with obtaining the correct data - from the laminate, threshold, platbands.

In order to correctly place an order in the door store and decide which doors to buy, you must first measure the interior doors.

To purchase doors, you will need the following information:

1. The width of the doorway.

It is very easy to freeze it. We take construction tape measure and measure at three to four points (bottom, top and middle - a must!). As a basis, it is better to take the minimum size obtained or the arithmetic mean if the wall can be corrected, for example, to break a little concrete or plaster. And this is of course in the event that the door block will not fit or the resulting gaps on the foam are too large and will not close with a casing.

Result: 920 mm (you got it: at the top 920, in the middle 925 and at the bottom 930 mm.). A standard 800 mm door will fit this width.

Advice: Since the installation of doors is the final stage of work and the new wallpaper will already be pasted over, glue them in such a way that there is an overlap on the opening. This will help to avoid problems when installing the trim on the door frame, which, with an opening width of 920 mm, may not overlap the pasted wallpaper, for example, indented from the edge of the opening. It is important that the walls, at least near the openings, be even, since the platbands are the rule that will show the quality of the repair right away!

2. Height

Several important points in height. The first thing to do is to measure in the same way as in the first case at three points, from the left edge, then from the right and in the middle. Secondly, it is necessary to take into account the level of the floor, whether it will change and to what height ( concrete screed, laminate, tile, parquet, etc.). It's easier when the finished floor is ready.

Result: 2100 mm (you got it: on the left 2120 in the middle 2110 and on the right 2100 mm.). Under this width, a standard canvas of 2000 mm is suitable. or not standard 2050 mm. The latter will not require modifications of the opening in height, but the standard one, 2 meter canvas and its platbands may not close a height of 2,100, and 2120 mm - they will not close for sure!.

Advice: First of all, consider the first tip! Still more important is that modern manufacturers doors in Russia are focused on an opening with a height of 2080 mm. This means that it is better to plaster and lower an unsuitable opening in advance, leading to standard view. At this stage, consider whether there will be a door with a threshold or not. The standard dimensions of the assembled door block according to the box can always be clarified on the manufacturer's website and from the supplier.

3. Wall thickness.

An important indicator when deciding on the standard of doors. It is necessary to measure at least four points. By analogy, we take a larger size.

Result: 120 mm

Advice: With a standard of 75 mm, we are dealing with the 120th wall and an order, followed by installation - either non-standard door frames, or with the purchase and installation of a frame expander - an extension (slope for interior doors). Installing a dobornik, a very common operation. Why and how to order or install an add-on, we consider in detail on the pages of our website.

4. Opening doors.

Determining the opening of future doors is quite simple. It is necessary to become facing the interior door, mentally pull it by the handle towards you and open it. At the same time, on which side the hinges will be, so is the door.

Result: Right

Advice: Think carefully about the future opening, taking into account convenience and fire regulations! In some cases, when inserting hinges and a lock under production conditions, it will be impossible to change the opening after purchase and delivery!

Here is what we ended up with:

  • Opening 920*2100*120
  • Door leaf 800*200 - Right
  • Extension 120 - 75 = 45 mm (requires an extension bar of 45 mm or more) or a non-standard box of 120 mm in width.

That's it - you can go to the store to buy new interior doors!

With independent measurements, it is necessary to understand that this article is for informational purposes only, is not a panacea, and possibly does not take into account complex and non-standard cases of such a diverse process.

No, then we invite

You will need to arm yourself with a tape measure, a sheet of paper, a pencil or a pen.

This is the simplest example of measuring doors. You will need to arm yourself with a tape measure, a sheet of paper, a pencil or a pen. The main values ​​necessary for the future order of doors are: door height, door width, wall thickness, side opening of the door.

* a rare case when a canvas is required higher or lower than the standard - 2 meters high

What width should I order for interior doors?

In the size of the door, the main characteristic is the width of the leaf. If the width of the doorway is 93 cm, then a door leaf 80 cm wide will fit into this opening.

For a door leaf with a width of 70 cm, the opening will be too wide, and for a leaf with a width of 90 cm, the opening will be narrow, since you also need to take into account the thickness of the box on both sides of the leaf, which is 2-3 cm at the groove of the box under the leaf . Of course, the ideal opening for a door with a width of 80 cm will be between 85 - 88 cm.

Table depending on the size of the interior door leaf on the width of the doorway

If the width of the doorway is... ...then the width of the leaf will be equal to

670 - 700 mm - 60 cm.

770 - 800 mm - 70 cm.

870 - 900 mm - 80 cm.

970 - 1000 mm - 90 cm.

Thus, it turns out that the canvas should be at least 7 cm narrower than the doorway. But you need to understand that a box thickness of 3 cm is a minimum, and mostly for laminated simple doors. Minus the porch in the box, such doors may be enough for 6 cm from the opening. That is, if 3 cm of the width of the leaf remains, then the door assembly can be squeezed in. But this will not work with veneered doors or with a telescopic box. They have more thickness. Yes, and for the foam, too, you need a place.

Dimensions of a simple laminated box.


Do you need extensions and what width?

An additional element is a bar for expanding the beam of the box. It serves to close the section of the wall not covered by the box bar. In order to correctly calculate the width of the required extension, you need to measure the thickness of the wall in doorway and subtract the width of the box beam, this will be required size dobor. Typically, the width of a typical interior door frame is 7 cm. If the wall thickness is more than 7 cm, then extensions are needed. An exception may be if you have "L" shaped platbands.

When buying doors, you need to consider the most wide size the thickness of the wall of the opening where the door is planned to be installed. Example: at the bottom the wall thickness is 11 cm, in the middle - 11.5 cm, at the top - 12 cm. This means that the width of the door frame (door beam + additional plank) should be 12 cm. Otherwise, if the box is less in width than the thickness of the wall , then the platband will not lie tightly on the box and the wall.

When installing a door in an opening with a wall thickness of 11 cm (in the middle); 12 cm (from above), a gap may form between the wall and the casing in the intervals of a smaller wall thickness (where the wall thickness is 11.5 cm). At this shortcoming recommended to use gypsum mortar, or alibaster (sold in hardware stores in small bags) to cover the gap between the casing and the wall. Or another option: level the wall with mortar, so that the thickness of the wall is everywhere along the contour of the opening.

The width of the extension must be equal to or greater than the part of the wall to be covered. Those. if the wall is 12 cm wide and the box is 8 cm wide, then you will need an extension at least 4 cm wide. But in stores, as a rule, they sell extensions at least 10 cm wide. In our case, then you can buy 1.5 sticks and cut them in half.

What height to order the interior door leaf?

The height of the opening must be measured along the side slope on both sides. The size of a standard door, which you can buy in our online store, is 200 cm in height. If the opening in height from the floor to the upper partition is more than 210 cm, then the platband (which is attached to the upper box) will not be able to close the opening, resulting in a gap between the platband and the wall.

In this case, it will be necessary to reduce the opening in height or install wide platbands. If the opening is less than 203 cm in height, then the door with the door frame assembly will not be able to "squeeze" into the opening of this size. Then 2 options are offered: 2. cutting the wall to expand the opening, which is much more expensive than the first option, but the door will not be subject to "non-production" changes.

How to determine the door opening direction?

To correctly determine the side of the door opening, it is necessary to stand facing the door in such a way that the door opens towards itself. If you open the door towards yourself and the hinges are on the right side of the opening is right, if when you open the door on yourself the hinges are from the left, then the side of the opening is left.

Notes

If you are renovating, doors are best installed last. First we make the floor, then the ceiling, then the walls, and lastly the doors. But if for some reason the doors need to be installed earlier, then the following should be considered:

When measuring doorways and openings, you need to pay attention to the floor and how it will be after repair. So, if in the plans of the owners it is planned to use flooring more than 0.5 cm thick, this value will need to be subtracted from the height of the openings.

If you have a difficult case or you can't figure it out, Then Call a Qualified Technician

on our website in the "Call the measurer" section.

There are a great many different subtleties and nuances when installing doors. Only a professional will be able to distinguish a doorway from a running one. Determine if doors need so-called extensions and which ones. Do technical calculations gaps between the door frame and the wall, including those through which various wires. And it also fits in there in which direction the front door will open (to the right or to the left), internal or outside(it all depends on how it will be located on landing). All this and more, a special plan of "measurements" is introduced, which is then transferred to the master installers.

Collaborating with professionals is a guarantee High Quality, saving time and effort, and most importantly - nerves.

Doors inside a dwelling can be standard or non-standard. The former are much cheaper. Before ordering products for interior openings it is worth finding out which door sizes are suitable for the existing openings, and whether standardized solutions can be dispensed with.

How to measure and what to measure?

When installing doors, it is not the dimensions of the door leaf that will be decisive, but the dimensions of the frame. To install it normally, it is worth deciding on the dimensions of the opening. It is necessary to correlate a number of parameters:

  • dimensions of the existing opening with dimensions unified canvas doors and door frames;
  • wall thickness at the opening with a width ;
  • take into account the presence or absence of a threshold.

Inside apartment buildings usually make standard openings, but they also need to be measured carefully. Modern design solutions may imply deviations from the standards. The dimensions of the openings should be determined after the old door frame (frame) is dismantled.

Calculation of the opening for a web of uniform width

To the height and width of the interior door, you need to add the dimensions of the box and mounting clearances (technological spaces). This is a simple calculation algorithm. Wherein:

  • Ludka (box) usually has dimensions of 25 mm on each side. This indicator can vary in proportion to the working load on the frame (door weight).
  • Mounting clearances are limited to 15-20 mm. They are needed to fix the box in the wall and level out irregularities, slope deviations.
  • There should be a gap of 2.5-3 mm on both sides between the hatch and the door leaf (5-6 mm in total) in order to guarantee free closing and hinges.
  • standard height threshold is 15-25 mm. If it is not done, then a gap remains between the interior door and the floor surface.
  • We calculate the dimensions of the opening for a standardized canvas 2000x800 mm.
  • Height: 2000 + 25 (frame) + 25 (threshold or gap under the doors) + 20 (upper mounting gap) + 3 (for unhindered movement of the door in the box) = 2075 mm. After rounding it will be 2080 mm.
  • Width: 800 + 2*25 (box) + 2*20 (mounting clearances) +5 (clearance for free hanging and movement of the door in the box) = 895 mm. If rounded, we get 900 mm.

Thus, for a door of 2000x800 mm, an opening of 2080x900 mm is needed (80 mm higher and 100 mm wider). If the dimensions of the opening are larger than the calculated ones by 2-3 cm on each side, this excess can be removed using polyurethane foam. For large gaps, you will have to adjust the opening.


Dimensions of standard doors inside residential premises

Door sizes standardized according to GOSTs significantly reduce the cost of construction and solve many other problems. With appropriate openings, the door can be ordered at any store. Interior openings are usually smaller than the opening for the front door to a dwelling. By the way, the width of the latter should be at least 80 cm, and for greater convenience - 85 cm.

It is allowed to make interior openings 60, 70, 80 and even 90 cm wide. There is little point in openings that are too narrow: after all, you need to carry furniture through them, household appliances, musical instruments and other things. Therefore, when installing interior doors, it is advisable to choose a canvas 80 cm wide. Then, for example, washing machine (maximum dimensions in plan 60x65 cm). Doors to the pantry can be made narrower.

The unified dimensions of doors (cloths) suggest a step of 50 mm (sometimes 10-30 mm).

  • With a door height of 1900 mm, widths of 550 and 600 mm are used.
  • With a height of 2000 mm, the width is 600, 700, 800, 900, 1200, 1400, 1500 mm.
  • Such dimensions are less common: height 1940-2030 mm with a width of 630-760 mm and a height of 2040 mm with a width of 660-1600 mm.

It will not be superfluous to take into account the requirements of domestic GOSTs for minimum dimensions doorways. They make up:

  • For bathrooms - 550 (600) mm by 1900 (2000) mm with a depth of 50-70 mm.
  • For kitchens - 700 mm by 2000 mm with a depth of 70 mm.
  • For rooms - 800 mm by 2000 mm with a depth of 70-200 mm.

The standard depth of frames for interior doors is 75 mm. With thinner piers (for example, drywall), their thickness sometimes has to be increased for normal door installation.
