How to properly measure a doorway. Entrance door dimensions. Non-standard doorways - solutions

Everyone knows that a well-done repair is an expensive undertaking. In order to perform all the work correctly and on time, everything must be thoroughly planned. And, of course, to buy everything suitable materials, everything should be well calculated and measured. The same applies to interior doors.

Why you need to know the dimensions of the opening

In order to choose the right door you like, you should know what size to buy a canvas and whether they will buy extras. It will be much easier to choose such a product if you know all the quantities. Without the help of a specialist, taking measurements with your own hands will not be difficult, but you should still take this process more seriously. Having the slightest errors in the calculations, there is a risk of purchasing products that will be smaller or, on the contrary, will not be able to fit into the doorway.

The final result of the work done will depend on the correctness of the measurements made, see the photo.

Required Tools

To make all the necessary measurements yourself interior door you will need tools. You will need a pencil and paper to record all the data generated. You can take all measurements with a tape measure. With it, you can measure the height, width and thickness of the doorway. Knowing all these dimensions, you can easily choose your favorite model of door products.

How to measure a doorway with old doors

This method is easier, and even a beginner can handle it. You will only need to remove the casing and measure everything external dimensions old door.

First you need to measure the width of the opening. Next is the length and depth. All data is recorded on paper. The process itself goes like this: you stand in the opening and take measurements, as shown in the photo. Existing platbands are not included in the calculation. If in doorway there is no canvas, then the dimensions of the opening and the thickness of the walls are measured.

To know the side of opening the product, you need to stand facing the door so that the product swings open on itself. If the hinges are on your left when opening, then the opening side is left, and vice versa.

If you do not like the dimensions of an outdated door, then it is recommended to call the master.

How to measure an empty opening

If you have an empty opening or the dismantling of an old door with a frame has already been completed, you decide to do all the measurement work yourself, then you should know that such work is more laborious and requires special skills. In this case, all measurements take place along the openings.

  • The doorway should have distinct lines. Protruding parts, foreign elements are not allowed. At correct measurement all possible changes should be taken into account, which include the installation of the ceiling, laying tiles and laminate. If you are doing repairs, then the doors must be installed at the last moment. This is very important, since a couple of centimeters can be added at the time of flooring. All previous measurements will be incorrect.
  • The border of the top of the opening must be parallel to the floor, see the photo. A deviation of more than five millimeters is not allowed. With the help of the level, vertical walls are also measured. During measurements, the walls of the opening should be clearly checked, they should be in the same plane.
  • Using a tape measure, the width, height of the opening and the thickness of the walls are measured.
  • It should be understood that only a correctly made measurement guarantees a quality installation. How to produce the right dimensions you can find out by watching the video.


If you cannot choose the model of an interior door of your size that you like, do not rush to make it to order. In this case, it will help you door block smallest size, and the delta will close when mounted.

In order to correctly place an order in the door store and decide which doors to buy, you first need to 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, break concrete or plaster a little. 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

Some 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 a 120th wall and an order, subsequent installation - either non-standard door frames, or with the purchase and installation of a box 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.

Measurement in the presence of old doors in the opening.

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

In this case, you have old doors. To be more or less correct make door locks, write down the results of the above values ​​for each door, this data will be needed to place an order in the store.

An example of the results of your measurement, in this example measure the old doors you have installed in width and height, the canvas and the thickness of the wall:
1. The width of the leaf of the old door, for example, is 700 mm., The height is 2000 mm.
2. The wall thickness of the doorway is 120mm.
3. On one or both sides of the door you need a trim (platband on both sides).
4. Threshold needed or not (for example: with a threshold)
5. The side of the door opening (for example, left.)
6. Do you need or do not need a locking mechanism (plumbing latch or second entrance), for example, you need a latch with a latch, as the door to the bathroom.

Let's clarify how to deal with the side of the door opening: you need to stand facing the door in such a way that the door opens towards you. If you open the door towards yourself and the hinges are on the right side of the opening is right, if when opening the door towards you the hinges are from the left, then the side of opening is left.

Approximately how your order will be prepared in the store:
1. Door leaf: 700*2000mm.
2. Door frame 1.2 sets. (2.5 pieces)
3. Dobor 50 mm wide 1 set. (2.5 pieces)
4. Casing on two sides (5 pcs)
5. Handle 1 pc. Latch 1 pc. Retainer 1 pc.
6. Loops 2 pcs. (left)

We have considered the simplest example, in most cases it is applicable. By analogy, one can measure all the doors you need. If you are not satisfied with the size of the old door and want to change it, then calling the measurer is required.

Independent measurement of empty openings.

Now consider more complex example taking a measurement! If you have an opening without doors, doors with frames have already been dismantled or have never been installed. In this case, we will measure already along the openings. We write down the results of the work done.
Example:
1. Opening width 800mm.
2. Opening height 2060 mm.
3. The thickness of the wall of the doorway (for example 120mm.)
4. On one or both sides of the door you need a trim (platband on both sides)
5. Threshold needed or not (for example: no threshold)
6. Sideness of tearing off the door (for example, right)
7. Whether or not a locking mechanism is needed (a plumbing latch or a second entrance), for example, a latch with a latch is needed, as the door to the bathroom.

For reference: the standard dimensions of the opening in a solid wall under a door with a leaf, for example, 700mm, should be as follows: width - 780 - 800mm, height from 2060mm to 2090mm. This opening height is for everyone standard doors should be within these limits, because the height of the canvases is standard and is 2000mm. The width of the openings varies. For a 600mm web - about 700mm, for a 700mm web - about 800mm, for a 800mm web - about 900mm, for a 900mm web - about 1000mm. This is due to the fact that the box adds another 50 - 60 mm to the width of the canvas. Those. a door with a leaf of 800mm will have a total width of 860mm and a height of about 2050mm.
An example of a complete set of a single-leaf (single-leaf door) opening with a width of 800mm and a wall thickness of 120mm ( standard size opening for a single-leaf door in a typical apartment)

1. Canvas 700*2000 mm. 1 PC
2. Dobor for refining the opening 50 mm. - 1 comp. (3 pcs)
3. Platband - 5 pcs.
4. Handle - 1 pc., Latch 1 pc., Retainer 1 pc.
5. Loops 2 pieces right.

Above examples of measuring interior doors fit in most cases, and you can focus on them, but measurement is still highly desirable. Maybe you have a special opening and it requires individual approach, and this can only be found out on site by a qualified specialist with installation experience.
Our company offers you a full range of services: professional advice, measurement of openings, quality installation doors, warranty. In our catalog interior doors are presented in a wide range.

Before choosing, purchasing and installing an interior door, it is necessary to correctly determine the width and height of the doorway, the thickness of the walls, calculate the dimensions of the leaf itself, and take into account technological gaps. Compliance with the following rules will ensure trouble-free operation and long term door services:

  • the width of the opening is measured cleanly between two vertical slopes; the height is taken equal to the distance between the plane of the upper slope and the level of the finished floor;
  • when measuring the opening without first dismantling the old door, measurements are made similarly to the previous paragraph, but only after removing the platbands;
  • in case of violation of the integrity of the slopes, a significant difference in height dimensions, the presence of an excessively wide or narrow opening, etc. contentious issues it is better not to take risks and contact a specialized organization; an experienced measurer will give reasonable recommendations and help resolve a non-standard situation.

When the dimensions of the opening are determined independently or with the participation of a professional, it is not at all difficult to calculate the appropriate door dimensions. To do this, take into account the following nuances:

  • geometric dimensions door leaf in width should be reduced by the standard gap, which is 35-60 mm from the left and right side;
  • the height of the door should be equal to the height of the opening minus 50-80 mm; the gap is left on the side of the upper slope, but at the same time, the level of the finished floor is taken into account.

In practice, it looks like this: with door leaf dimensions of 700x2000 mm, the width of the opening should be 770-820 mm, and the height should be 2050-2080 mm, in case double doors with leaf dimensions of 2x600x2000 mm - this is 1270-1320 mm wide and 2050-2080 mm opening height. Not recommended to go beyond established norm sizes, otherwise it is fraught with either deformation of the door, or a significant weakening of its fasteners.

As for the thickness of the wall, the measurement results have a direct impact on the size and number of extensions. Modern telescopic dobors complete with telescopic architraves and a box are very technologically advanced. Their width is adjustable and fixed in place. With a wall thickness of 80 mm, extensions are not used.

How to measure front door

In order for the front door to fully meet its purpose, be functional and serve reliable protection house, before installing it, it is necessary to correctly measure the opening, determine the dimensions of the door block, and provide for the required gap size. Errors and miscalculations will cause operational difficulties or general unsuitability. installed door. The basic rules for measuring work are:

  • measurement of the height and width of the opening "in the clear": from the left slope to the right, from the upper slope to the bottom of the opening;
  • when replacing an existing door, the dimensions of the opening are determined after preliminary dismantling of the platbands and providing access to the edge of the wall;
  • in case of unsatisfactory condition of the slopes: painting the masonry walls, violating its verticality, it is more correct to turn to the services of specialists; professional approach will avoid possible mistakes and unnecessary expenses.

After measuring the opening, determine the required size of the front door. In this case, the dimensions of the door unit should differ by the size of the mounting gap between the wall and the frame. The distance between adjacent surfaces is set as follows:

  • across the width of the opening: from 10 to 50 mm on each side of the vertical slopes;
  • along the length of the opening: 10-50 mm between the upper slope and the crossbar of the door block, leaving a small distance from the side of the threshold.

For example, with dimensions of a door block of 860x2050 mm, its width can be in the range of 880-960 mm, and its height can be 2070-2100 mm. With dimensions of 980x2050 mm, these are 1000x1080 mm and 2070x2100 mm, respectively. Everything is extremely simple and accessible for self-calculation.

The presence of a gap is necessary not only from the point of view of installation, but also in the event of thermal deformations of the front door. Maintaining the required distance has special meaning when installing wooden blocks, however, its value should not exceed the maximum allowable sizes. An excessively large gap will cause a significant deterioration in the heat-insulating ability and fastening strength of the entire structure. That is why, with a significant exaggeration of the width of the opening, it is recommended to partially fill it and thereby reduce the initial dimensions. If the reverse situation occurs and the existing width is insufficient, then the opening is further expanded.

An important stage in the manufacture of the door is the removal of the size of the opening. If the door is smaller than the opening, it will not be possible to install it, or the door will be poorly fixed, unreliable, which will not allow it to fully perform its functions. If the door is larger than the opening, it will take time, certain skills and costs to expand it, which is also undesirable. Therefore, the measurement of the size of a metal door must be approached very carefully.

To measure the opening of the front door, it is necessary to free it from old design. If the dismantling of the old door is currently impractical, the opening must be freed at least from the platbands so that the walls are free. If, during dismantling, part of the wall collapsed, it is necessary to eliminate this shortcoming and only then proceed to measurements. It is also necessary to free the opening from finishing materials, that is, take measurements directly on the walls.

How to measure the opening and entrance metal door for installation

You can measure the opening under the door as follows.

  1. Take a centimeter and measure the width and height at several points. It must be remembered that openings that are ideally even from a geometric point of view do not exist, the width and height can “walk”. So, the width is measured from the bottom, top and middle. The same goes for height.
  2. Some openings may narrow or, conversely, expand towards the exit. This must be taken into account. Also remember that the walls may have vertical deviations, therefore, when taking measurements, use a plumb line or a laser builder.
  3. Width and height are measured first while standing inside the room, and then outside. If the apartment is being renovated and you have not done the floor yet, it is better to wait a little with door measurements. In addition, thresholds must be removed from the floor, they will interfere with measurements.
  4. AT standard rooms the dimensions of metal doors are from 800 to 900 mm in width, from 2070 to 2300 mm in height. Dimensions door structure must be 2-3 cm smaller than the opening so that the unit can be adjusted during installation. The gaps will then need to be filled with mounting foam. However, the opening should not be more sizes doors more than 7 cm wide and 3.5 cm high. Otherwise, the door will be less resistant to breaking.
  5. To measure the thickness of the wall in which the door block is supposed to be mounted, a caliper is used. If it is not available, it can use two rulers. You need to vertically attach them to the wall on one side and the other. The distance between the rulers is the thickness of the wall.
