How to measure an interior door using an old one. How to measure the opening for the installation of the front door, comply with the norms and not make a mistake? How to measure an empty opening

If there is a need to replace the input or interior door you need to check the doors first. 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 are 80 cm wide at interior doors and up to 100 cm at entrance doors.

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 mounting foam. But with a significant difference between the dimensions, resistance to burglary suffers.
5. Not everyone knows how to measure a metal door correctly. 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 need a tape measure, building level or plumb. Before starting work, it is worth clearing the passage from what will interfere with obtaining the correct data - from the laminate, threshold, platbands.

If you decide to take the measurement yourself, read the information provided to do it correctly.

Measurement of an empty opening

Simplest measurement option when a new empty doorway is measured or the old door is completely dismantled. In this case, you need to do:

1. Width measurement doorway . Performed at the top and lower part opening, since the opening can be made not in level and have a constriction from one side. In this case, it takes the smallest of the obtained values ​​\u200b\u200b- this will be the width of the opening. Standard Width door leaf - 60, 70, 80, 90 cm, frame thickness - 2-4 cm, so optimal width opening should be: 65-68 cm, 75-78 cm, 85-88 cm, 95-98s m.

2. Height measurement doorway . Performed similarly measurement by width: on both sides and the minimum of the measured values ​​\u200b\u200bis taken. The standard height of the door leaf, manufactured by Belarusian and Russian manufacturers, 200 cm, frame thickness from 2 to 4 cm, so to install a door without a threshold, optimal height opening should be 204 - 208 cm.

3. wall thickness measurement. The door frame is usually made 7 cm wide, if the width of the wall is greater than this value, then the remaining part is usually closed with an additional plank (standard sizes 10, 15, 20 cm). Please note that if the wall narrows, it is necessary to take the maximum measured value so that the width of the extension is exactly enough. If the wall thickness exceeds 26 cm, then, as a rule, dobors are not installed, but a box is installed and slopes are made.

Measuring the opening with the old door installed

Measuring an opening in which an old door is still installed is a little more difficult than an empty one. The principle of performing measurements is exactly the same as in the first case, but there are nuances:

1. To perform the measurement, it is necessary, if possible, to dismantle the old architraves on one side and measure the height and width of the doorway, as indicated above.

2. The thickness of the wall is measured from platband to platband.

These dimensions are the information that makes it possible to correctly place an order and eliminate problems during installation.

In order for the new door to optimally match the existing opening, it is necessary to determine the parameters of the elements included in the kit door frame. At the same time, there are some nuances that affect the location of the doorway and appearance.

Before buying a door, you need to make measurements of the doorway.

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

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

Work order

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 of the floor is taken into account. If the wall is thicker than 10 cm, then it will be necessary to determine the size of the additional elements. With the help of these details, slopes are formed.

If the doorway is narrow, then perhaps you should consider widening it. This can come in handy when shipping larger furniture. The size of the door frame should provide a gap between this box and the wall along the entire perimeter of 3 - 4 cm, which is then filled construction foam. The size of the additional elements should be such that, in total with the thickness of the door frame, the thickness of the wall is obtained. At the same time, a processing allowance must remain on the additional element to ensure a snug fit of the casing to the wall. Be sure to determine the opening direction of the door in order to provide sufficient space for opening and correct installation door hinges.

Entrance doors according to the rules fire safety should open outward.

There are non-standard doors. For example - with an arched vault. How to measure parameters in this option? Each non-standard case requires individual approach. In all cases, preference should be given to doors with a finished frame. When measuring, it is necessary to determine the presence of various communications that affect the opening. At the measurement stage, all the design features of the doors and the wishes of the customer are recorded. Competent measurement will ensure the proper quality of door installation.

Entrance doors are of great variety. On sale there are standard and not 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 choosing, they are guided primarily by size. doorway, the value 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 regulations, it is recommended to open front door inside - 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

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.

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 serve 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 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 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 provides 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.

At the time of buying new apartment, at home or building a new cottage, it is required to install a new door. There are many factors to take into account in order to right choice. The door must meet the requirements for sound insulation, fire safety, thermal insulation, reliability of the leaf and lock. But it is equally important to take into account the dimensions of the door in order to install it without any problems.

If the doorway standard sizes, then the difficulties in choosing suitable model will not occur. However, there are companies that will manufacture any design according to individual sizes. But its cost on average will be 30% more than that of standard variant. And if a premium class model is chosen, then this difference will hit the pocket. In order not to overpay for this, many adjust the size of the passage to the standards.

Most companies that manufacture such products provide measurement and installation services. But if you wish, you can perform these procedures yourself. In any case, you need to know how to correctly and simply measure the front door.

What to consider when measuring?

Measuring the doorway is not a particularly difficult and time-consuming task, the main thing is to follow all the recommendations and make correct calculations. In order not to confuse the numbers of the measured parameters, it is easier to write them down. To estimate the size of the opening in its purest form, you need to take into account all five parameters:

• Height is the distance from the floor to the upper horizontal plane of the passage;
• Width - this is the minimum distance between the side walls of the passage;
• Depth is the thickness of the wall into which the door will be installed;
• The total slope of each of the planes of the opening;
• Roughness - deviation from the average value in certain areas of the planes.

Each of these parameters must be measured separately. At the same time, remember that the width and height of the passage should be much larger than the parameters of the door itself, since here it is necessary to take into account the dimensions of the box, plus leave a margin of 2-3 centimeters to install it in the opening. If everything is done correctly, then there will be no problems.

Since most doorways in apartments have basically the same indicators, manufacturers produce standard models according to these parameters. In this regard, the prices for standard products are much lower than for individual ones. In Russia, the standards for single-leaf entrance doors are 860 × 2050 mm and 960 × 2050 mm. These are the dimensions of the door block. They are designed for passages of at least 880 × 2100 mm and 980 × 2100 mm, respectively. For bivalve door structures– 1600 × 2050 mm.

If the dimensions of the opening are non-standard, then you can order the front door. But when ordering, keep in mind that the width and height must be a multiple of 10 cm.

Width

The measurement of the front door begins with this parameter. For standard openings door leaf, it is 800 or 900 mm. Accordingly, with the box, these parameters will be 860 mm and 960 mm, and the width of the opening must be at least 880 and 980 mm. To find out the exact parameters of the opening in width, three measurements are taken: at the top, bottom and in the middle. If the protruding places are visually visible, then the measurement must be done on them too. As a result, the smallest distance is taken as the width of the opening.

Height

How to measure height? This is also easy to do. By the same principle, the height is measured in three places: along the edges and in the center. Measurement is made from the floor to the upper plane of the opening.

standard door has a height of 2000 mm, with a box this parameter will be 2050 mm. Therefore, the passage height must be at least 2070 mm. Further, during installation, these gaps in width and height are foamed and plastered.

opening depth

This value is no less important. The thickness of the door is much less wall. Therefore, a box of suitable thickness is selected. Standard products are designed for a wall of 30-40 cm. If the box does not completely cover the opening, then it is increased by including additional sections - extensions.

To determine the depth of the passage, three measurements are also taken (up, down, center) along each of the planes of the door passage. The maximum number is taken as the depth.

Opening irregularities

Sometimes situations arise when the opening has irregularities horizontally or vertically. These can be local defects (bulges, pits) or a general slope of one of the planes. If local irregularities can be eliminated (chipped, puttied), then it is difficult to do this with a slope. To determine it, use the bubble or laser level and make calculations based on minimum distance. For example, there is a horizontal skew on the top surface of a doorway. With the help of the level, the lowest point is determined - it will be the height of the passage.

Another way to determine the slope is to measure the diagonals. This method is used everywhere in construction and helps to determine the curvature of the planes relative to each other. This principle is based on the rule of equality of diagonals. Since the opening is, in fact, a rectangle, then its diagonals must be equal. To determine this, the distance is measured from the upper right corner to the lower left and from the upper left to the lower right along one wall. These parameters must match or be close to each other (a maximum deviation of 1-2 cm is allowed).

Dimensioning, elimination of defects

If during measurements larger than standard sizes are obtained, then it is better to lay part of the passage with a brick or other wall material with a large deviation. If it is small, then this gap can be plastered with a cement-sand mixture.

If, after taking measurements, it turned out that the opening is less than the standard one, then it is advisable to increase it. To do this, part of the wall is removed, and the irregularities are plastered.
