How to correctly measure the opening of an interior door. How to measure doorways yourself? (for preliminary calculation)

It is important not only to choose the design and color of the structure, but also to correctly determine the dimensions of the paintings for each room. To do this, you must first make accurate measurements of the doorways, and only then, based on this information, calculate the dimensions of each door block.

Standard and non-standard doorways

In typical high-rise buildings, doorways usually have a standardized width depending on the room:

bathrooms and bathrooms - 63 ... 76 cm;
kitchen - 77 ... 87 cm;
living rooms - 88 ... 110 cm;
opening for the front door to the apartment - 90 ... 110 cm.

The height of the opening in kitchens and rooms varies from 204 cm to 210 cm, and in bathrooms and toilets there are often passages 194-203 cm high, which requires the installation of lower canvases or changes in the dimensions of the installation site.

Passages of non-standard width and height are usually found in old buildings and private cottages. Also, often as a result of redevelopment, even in standard apartments, instead of standard openings, wider or higher aisles are equipped.

You can take measurements of doorways by inviting a professional measurer. But if you decide to measure yourself, then you must first learn the rules for performing this operation - how to correctly measure the width of the opening, how to correctly measure the height of the opening and how to measure the thickness of the wall.

How to correctly measure the width of the opening?

The width of the doorway is measured at three points - top, middle and bottom. From the values obtained, the minimum result is selected, and it will be the width of a particular doorway.

In typical apartments, the following standards for the width of door structures are usually followed, setting:

in the kitchen - canvases 70 cm;
in the bathroom and toilet - products 60 or 55 cm;
in rooms - models 80 cm;
as a second entrance door - 90 cm options.

Most major manufacturers produce door leafs adapted to the dimensions of typical passages. The width of the canvases is usually equal to 600 mm, 700 mm, 800 mm, 900 mm. Some brands also have models with a width of 550 mm and 400 mm, but their choice is small. Such a variety makes it easy to choose a canvas for a typical room.

If you have old doors installed and you are satisfied with their width, then you can simply measure the parameters - let them correspond to the dimensions of the new door leaf.

How to correctly measure the height of the opening?

The dimensions of the opening in height must also be measured at three points - along the side slopes and in the middle. From the obtained values the smallest is chosen, for this parameter it is necessary to select doors.

The standard height of the door leafs is 2 meters, they fit into the installation place with a height of 204 to 210 cm. With a higher passage height, the width of the standard trim may not be enough to mask the junction of the door frame and the wall. In this case, wider architraves are used to decorate the door structure or a portal with a capital is installed.

In the model range of some brands, you can find models with a height of 1.9 meters. They are installed in bathrooms and toilets. Such canvases are suitable for aisles with a height of 203 cm or less.

IMPORTANT!

Even if you are sure that the repair in your house is done perfectly, you should still measure the doorway at three points in height and width. Otherwise, you run the risk that the finished door unit will be wider or higher than the installation site, and you will have to bear unplanned costs.

How to measure wall thickness?

To determine the wall thickness, measurements are taken at three points and the largest of these values \u200b\u200bis chosen. The standard for doorway wall thickness is 6 to 8 cm, which is what most manufacturers of interior doors are guided by.

If the thickness of the wall is greater than the width of the box beam, it is necessary to install door extensions. These are strips of various widths, with the help of which door slopes are formed. They have the same texture and color as the entire door structure.

Door extensions not only give the opening an aesthetic appearance, but also protect the slopes from scratches and abrasion. Therefore, do not save on their installation.

When to take measurements?

An accurate measurement of the dimensions of the doorway is carried out after finishing the walls and laying the decorative flooring. Otherwise, there is a risk that the selected doors cannot be installed due to the fact that the opening is smaller than the dimensions of the door block.

But it is necessary to pre-measure the doorway even before performing a rough finish. This will allow you to choose the size of the opening in accordance with the line of standard canvases. And then you will not have to overpay for interior doors of non-standard sizes.

It is not difficult to reduce the size of the passage; brick, drywall or wood are usually used for this. The expansion of the installation site can affect the strength of the wall, this operation must be carried out with caution, strictly observing the established building codes.

Why are measurement errors dangerous?

Professional measurements are a guarantee that the doors you have chosen can be installed quickly, without problems and without additional financial costs. After all, it is far from always possible to increase the size of the installation site, especially when it comes to a load-bearing wall. And if the finishing of the walls has already been completed, then to narrow the passage you will have to spend a lot of effort and additional money.

If you are not sure about your measurements or do not want to take risks, then it is best to purchase doors with a turnkey installation. In this case, the seller is responsible for the correct measurements, so you can be sure that each doorway will correspond to the dimensions of the leaf, and if there are errors, all replacements will be made at the expense of the installer. You can order a turnkey installation service in the online store of the Porta Prima factory or in sales outlets.

Swing door dimensions

Determining the dimensions of a swing-type door is carried out taking into account the height and width of the leaf, the thickness of the door frame, the presence or absence of a threshold.

The passage parameters for mounting a swing door block are calculated according to the following rules:

opening width = web width + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm;
opening height when mounting doors without a threshold = leaf height + frame thickness + mounting gap 2 cm x 2 + technological gap 3-5 mm;
passage height when installed with a threshold = web height + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm.

Using these simple formulas, you can easily calculate the dimensions of an interior door for each room in an apartment, house or office.

Don't forget about extras. Additional strips are available in different widths, they can be joined together and cut along, which allows you to choose a decorative design for a wall of any thickness. With their help, you can also mask the vertical deviation of the slope; for this, the bar is cut off in the form of a wedge.

Sliding door dimensions

Sliding doors today are increasingly replacing traditional hinged designs.

The dimensions of sliding systems depend on the type of mechanism used:

sashes move parallel to the wall;
the canvas goes inside the wall into the cassette;
panels overlap when opened.

For example, for sliding door structures, the leaf should be 5-7 cm wider than the opening. This is due to the fact that such doors, in fact, perform the function of a screen and should block the passage from the side. Therefore, the leaves can be significantly wider, but not narrower than the width of the passage.

If a sliding door-pencil case is installed, its width is selected so that the canvas protrudes slightly from the wall. This allows you to conveniently close the doors.

For wide openings, designs of two or more wings are used, which are selected from standard-width canvases. In this way, it is possible to block passages of almost any size.

Non-standard doorways - solutions

If your apartment or house has non-standard sizes of openings, then the best solution would be to narrow or expand the passages to standard dimensions. This will allow you to install standard interior doors instead of ordering custom-sized canvases.

The advantages of installing door blocks of standard sizes include:

fast installation time - canvases are available in stock;
much lower price than models of atypical sizes;
a wide range of designs and colors.

If the selected canvas does not fit in the height of the doorway, you can trim it. It is undesirable to do this on your own, since you need to use a professional tool. It is best to contact a company that provides such services.

In some cases, it is not possible to change the dimensions of the passage for technical or financial reasons. Then you have to order the manufacture of non-standard doors. They cost 30-40% more than mass-produced products, and their production usually takes several weeks.

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 for installing 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 fire safety standards, it is recommended to open the front door inward - this allows rescuers to quickly enter the building in an emergency and provide assistance to residents.

Standard dimensions of entrance doors

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

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.
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.
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. As a rule, the thickness of a 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

When choosing a 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

It should be remembered that when installing the door unit, it is necessary to maintain technological gaps along the perimeter of the opening in the amount of 15–25 mm. This is due to the installation 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 the rectangular space allocated for the installation of a door block. 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 dimensions of the 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 are 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. Additional bars are installed in the wooden walls. 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 to the desired 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 at the 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 play a role. 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:

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.
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.
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 of the old door is done in the 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 a supporting wooden beam falls out, it is necessary to strengthen the opening before proceeding with measuring the dimensions for the new door. Dilapidated plaster is beaten off, and wooden parts are firmly fixed 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. The duration of operation, reliability and appearance of the entrance to the building depend on the correct choice of the type of doors and installation. Turning to experienced professionals, you will spend more money, but you will get guarantees that are worth it.

Before you buy interior doors, you need to know the answers to three questions

1. What size door leaf do I need (width and height)?

2. Do you need extensions and what width?

3. What should be the opening side of the doors?

Finding out the answers to these questions for each doorway is quite simple. Below are described and shown all the features of the method of measuring and determining the required dimensions of doors and accessories for them.

What size canvas to choose for your doorway?

There are no standard doorways. To determine the width and height of the door leaf you need, you need to measure the doorways in which you plan to install the doors.

How to determine the width of the door leaf?

To determine the desired width of the canvas, we determine the width of the doorway. To do this, we measure the opening in three places - at the top, bottom and in the middle. The smallest value will be the width of your doorway.

If you still have old doors in the doorway, then everything is much simpler. We measure the width and height of the old door leaf.

As a result, the width of the leaf should be narrower than the doorway by 80-100 mm for doors with a simple (non-telescopic) door frame, and by 100-120 mm for doors with a telescopic frame.

But since the standard dimensions of the width of the canvases are multiples of 100 mm (600, 700, 800, 900), then with a certain width of the doorway, a narrowing or expansion of the opening will be required. See the table below for details.

READY SELECTIONS

Table for selecting the width of the leaf according to the width of the doorway

opening width (mm)	Web Width (mm)	Work may be required
450-480	400	opening extension
480-500
500-600		opening narrowing
600-620	550	opening extension
620-650
650-680		opening extension
680-700	600
700-750	600	opening narrowing
750-780	700	opening extension
780-800
800-850		opening narrowing
850-880	800	opening extension
880-900
900-950		opening narrowing
950-980	900	opening extension
980-1000
1000-1050		opening narrowing

It is possible not to narrow or widen the opening, but to order doors of non-standard width exactly to fit your opening. But such an order can be made not at all factories. For example, such a door factory as "Zodchy" makes doors of non-standard width, a multiple of 5 mm, in 2-3 weeks.

How to determine the height of the door leaf?

The height of the opening is measured in the same way as the width of the opening. The measurement is made in three places and the smallest value is selected.

The standard height of the canvas is 2 meters. For a standard leaf, the height of the opening should be 2060-2100 mm.

If the height of the doorway is below 2060 mm, then you will need to either file the door leaf or order a lower height.

If the height of the doorway is higher than 2100 mm, then either the narrowing of the opening will be required, or doors of a non-standard height must be ordered.

Not all manufacturers produce doors of non-standard height, but those that do increase the cost of doors by 30-50%. For example, doors from the Princip, Vladimir Doors, Verda factories are not made in non-standard sizes.

SELECTION OF DOORS OF NON-STANDARD WIDTH:

How to determine the door opening direction?

If you have chosen asymmetrical doors (that is, if the doors are visually divided in the middle by a vertical line, then the right half will differ from the left) or doors into which fittings are embedded at the factory (for example, the doors of the Mario Rioli factory), then you must definitely decide on door opening side - left opening or right opening.

10 problems that most buyers of interior doors most often face >>>

1. Stand on the side of the doorway into which the doors will open.

2. We open the doors towards ourselves and look at which side the door hinges will be.

3. If the door hinges are on the right, then this is a right-hand door, if on the left, then it is a left-hand door.

If you are still not sure about the size of the door leaf you need, then it will be more reliable to call a measurer - a door specialist.

In addition to the dimensions of the canvas, you also need to find out if extensions are needed for your doorway.

What accessories and in what quantity are required for doors?

To install a door in a doorway, you need a door frame. To hide the gap between the door frame and the wall, platbands are needed. If the wall thickness is more than 70 mm (greater than the thickness of the box), additional boxes will be required - box expanders.

Telescopic and simple accessories

Telescopic components are called such components, in the set of which the platbands are “L”-shaped and are attached to the door frame and extensions by inserting the platband ridge into the groove of the box or extension.

How many door frame posts are required?

To install a single-leaf swing interior door without a threshold, 2.5 racks of the door frame are required. If the door is planned to be installed with a threshold, then 3 racks are required - this is the floor of the rack from above and the floor of the rack from below. the threshold of the interior door is part of the door frame. In our catalog of doors, by default, there is the required number of frame racks for doors without a threshold.

How much cash is required?

As standard, by default, a set of single-leaf swing doors includes 5 platbands - these are 2.5 posts on one side and 2.5 posts on the other side. There are cases when platbands are placed only on one side, and on the other side they ennoble slopes with plaster, tiles, etc. Platbands on the one hand are installed most often in a bathroom or when the opening is in a thick wall.

Are extras needed?

The extension is an expansion element of the door frame, which is required if the wall thickness is more than 70 mm. To determine the thickness of the wall, you need to measure the thickness of the wall in three places on each side of the doorway.

If the wall thickness is from 70 to 80 mm, then extensions are definitely needed for a simple non-telescopic box. With telescopic architraves you can do without extensions

If the wall thickness is more than 90 mm, then extensions are definitely needed, even if they are telescopic.

An example of a ready-to-install door kit with extensions.

What width dobori need?

The extensions of almost all manufacturers have a standard width - 100 mm, 150 mm, 200 mm. The width of the door frame is usually 70 mm. But everywhere the thickness of the wall is different and therefore it is almost always necessary to cut the extensions along. Thus, if the wall thickness is from 70 to 170 mm, then additional 100, etc. will be required. See the table below for details.

Width selection table

wall thickness	Extension width
wall thickness		Telescopic
	donations are not needed	donations are not needed
70 - 80 mm (90 mm)		donations are not needed

How many racks of extensions do you need?

If the wall thickness is more than 110 mm, then the number of racks of extensions is equal to the number of racks of boxes

If the wall thickness is less than 110 mm, then the number of extensions depends on the number of doors. extensions during installation by the master will be sawn along and from one extension you will get two. Therefore, for example, for two openings, in which the wall thickness is 100 mm, one set of extensions is required - this is 2.5 sticks.

Standard and non-standard doorways

In typical high-rise buildings, doorways usually have a standardized width depending on the room:

bathrooms and bathrooms - 63 ... 76 cm;
kitchen - 77 ... 87 cm;
living rooms - 88 ... 110 cm;
opening for the front door to the apartment - 90 ... 110 cm.

How to correctly measure the width of the opening?

The width of the doorway is measured at three points - top, middle and bottom. From the values obtained, the minimum result is selected, and it will be the width of a particular doorway.

In typical apartments, the following standards for the width of door structures are usually followed, setting:

in the kitchen - canvases 70 cm;
in the bathroom and toilet - products 60 or 55 cm;
in rooms - models 80 cm;
as a second entrance door - 90 cm options.

If you have old doors installed and you are satisfied with their width, then you can simply measure the parameters - let them correspond to the dimensions of the new door leaf.

How to correctly measure the height of the opening?

In the model range of some brands, you can find models with a height of 1.9 meters. They are installed in bathrooms and toilets. Such canvases are suitable for aisles with a height of 203 cm or less.

Swing door dimensions

Determining the dimensions of a swing-type door is carried out taking into account the height and width of the leaf, the thickness of the door frame, the presence or absence of a threshold.

The passage parameters for mounting a swing door block are calculated according to the following rules:

opening width = web width + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm;
opening height when mounting doors without a threshold = leaf height + frame thickness + mounting gap 2 cm x 2 + technological gap 3-5 mm;
passage height when installed with a threshold = web height + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm.

Using these simple formulas, you can easily calculate the dimensions of an interior door for each room in an apartment, house or office.

Sliding door dimensions

Sliding doors today are increasingly replacing traditional hinged designs.

The dimensions of sliding systems depend on the type of mechanism used:

sashes move parallel to the wall;
the canvas goes inside the wall into the cassette;
panels overlap when opened.

If a sliding door-pencil case is installed, its width is selected so that the canvas protrudes slightly from the wall. This allows you to conveniently close the doors.

For wide openings, designs of two or more wings are used, which are selected from standard-width canvases. In this way, it is possible to block passages of almost any size.

Non-standard doorways - solutions

The advantages of installing door blocks of standard sizes include:

fast installation time - canvases are available in stock;
much lower price than models of atypical sizes;
a wide range of designs and colors.

It is important to know how to measure the opening correctly in order to finally order a model that is ideal for your parameters. You can call a specialist at home or carry out the entire procedure yourself, the measurement process will not take much time.

Before installing a new door, it is important to measure the opening correctly.

Required indicators

In order to correctly measure the door, you will need to determine a number of indicators. For the convenience of work, it is recommended to write out all the positions on a sheet of paper in advance and find them sequentially one after another in the same order.

So, in order to measure the entrance or interior door, it is necessary to determine the following indicators:

width - the distance between the side elements;
height - the distance from the floor to the top floor;
depth - the thickness of the wall in the opening;
slope - the presence of distortions;
evenness - areas where the value of the indicators has certain deviations.

Necessary indicators for the correct measurement of the door

Door width

Measuring the door begins with determining its width. Doing it yourself will not be difficult. If we are talking about standard openings, often their width is 80 cm for the interior and 90-100 cm for the front door.

The easiest way is to independently measure the distance between the side supports at the bottom of the passage, the floor can serve as a guide. Nevertheless, to clarify the dimensions, it is necessary to carry out auxiliary measurements at least at two more points: from above and in the center. For work, only a tape measure is enough.

Correct measurement of the width of the door and doorway

opening height

The next indicator is . Approximately this value is 210 cm. In order to find out how many centimeters is the distance from the floor to the top of the opening, you will also need a tape measure. It is not always convenient to work independently in this case.

New doors are recommended to be installed in the opening after laying the flooring. This is especially true if you are planning to order an interior door. In this case, you do not have to calculate the thickness of the flooring or cut the elements of the door structure directly during the installation process.

You also need to measure the height at several points, the main reference point is the center. Measurements must be taken on the inside of the opening. All three values may differ from each other, which will affect further measurements.

For a more accurate determination of the height of the opening, the measurement is made in three places

additional characteristics

The width of the opening is different from the width of the door itself. It is measured in the same way. At the same time, please note that you need to order a box a few centimeters less, since technological gaps for installation are provided here. Also take into account that the width of the box will be larger than the canvas. There should be small gaps around the perimeter to ensure the free movement of the door.

The basic measurement of the entrance or interior door is completed by determining the thickness of the elements. For the entrance, this figure will be greater than for the interior door. In fact, this value depends on the thickness of the wall itself. The box must completely cover the opening. If the value is too high, the additional installation of extensions is provided.

Measurement of the width of the opening is carried out according to the same principle as doors.

opening evenness

It is also important to determine such parameters for the future door that will allow you to align the opening. This is important not only to facilitate the installation process, but also to improve the further functioning of the structure.

First of all, you need to check the vertical of the opening. For this, a level or a special plumb line is used. The rule of three points is also observed here: left, right, center. The next parameter is the diagonal. Using a tape measure, measure the distance inside the opening from the top corner on one side to the bottom in the opposite corner. Both indicators for each combination of sides must match, or at least not have serious deviations. If the values are very different, this will be noticeable even at the stage of carrying out the basic measurements, since the diagonals depend on the height of the sidewalls and the width of the top and threshold.

The evenness of the opening is an important indicator when measuring the door.

The presence of serious distortions will affect the durability of the fasteners, their normal operation and may lead to a deterioration in the overall appearance of the passage.

Elimination of defects

To install the door as correctly as possible, without distortions, it is necessary to make a slight adjustment to the dimensions of the opening. If serious irregularities were identified, the best way out of the situation would be to plaster the opening and cut off the sagging.

If you want to display a flat wall or partition, you can immediately take care of removing the ideal opening by attaching drywall sheets to the frame. In the future, it is required to superficially plaster the opening.

Carrying out a thorough measurement allows you to determine the ideal parameters for choosing a new door. This will facilitate the installation process and will positively affect many other aspects.
