The width of the door frame of the interior door is standard. Standard sizes of interior doors with a frame. How to correctly measure the opening for an interior door

When choosing interior doors, the main thing that you need to pay attention to is their dimensions. Indeed, in order to perform their functions, they must clearly stand in the opening, or in other words, have suitable parameters in width, height and thickness. There are no uniform established standards that all manufacturers must adhere to. But there are building codes, based on which doorways are made. Therefore, the width, height and thickness of the door directly depends on these indicators for the doorway.

Canvas dimensions

Based on the dimensions of the doorway, the standard width of the finished door of domestic manufacturers can be in the range from 550 to 900 mm. European products can be 600, 700, 800 or 900 mm in width.

IN apartment buildings, as a rule, the size of the opening, and therefore the door, differs depending on the purpose of the room.

The width of 550-600 mm is usually made for the door to the toilet and bathroom.
An opening of 700 mm is constructed at the entrance to the kitchen.
Doors of 800 mm separate living quarters.
A 900 mm wide leaf is often installed as a second door at the entrance.

Most common thickness modern doors can lie within 35-40 mm. But deviations are possible both in one and the other direction. It is influenced by the types of products and the material from which they are made. So, the thickness of sliding structures can be as little as 20 mm. And the canvases made of wood can be up to 50 mm.

A few decades ago, the height of the door could have two values: 1.9 or 2 meters. Today, due to the use of different styles and design solutionsparameters offered by manufacturers can reach 2.1 and even 2.3 meters. Our height standards are 2 meters, and 2.1 in Europe. It should be noted that in recent years, designers and builders increasingly rely on foreign standards.

Box dimensions

Doors can be sold with or without ready-made frames and fittings. It is a U-shaped structure and is mounted along the perimeter of the opening, helping to fix the canvas with fittings. Standard sizes door frames for interior doors will differ from each other, and depend on the size door leaf... Therefore, it is better to buy a door assembled with a ready-made box, fittings and trims.

The door frame is made of bars, which may differ in parameters. Their width ranges between 15 and 40 mm, but values \u200b\u200bof 30-35 mm are considered optimal. If they are observed, the reliability of the entire structure and a long service life are ensured.

The thickness of the box must match the thickness of the wall. This value is important because it should not exceed the width of the opening in which the installation will be made. For brick walls the standard thickness is 75 mm, and for wood - 100. If the structure is narrower, then you will need to use special additional elements. And the box, which is larger in size than the wall, cannot be neatly and securely fixed.

When assembling the box manually, to determine the size of the vertical posts, the height of the leaf and the thickness of the horizontal strip, the mounting gap and the size of the ventilation gap or threshold are taken into account. The size of the horizontal part is determined based on the width of the door.

Sizes of openings

Knowing the standard dimensions of interior doors with a frame and fittings, you can easily determine the width of the opening during the construction of walls and the construction of partitions. To do this, a double width is added to the width of the canvas. door frame interior door and the size of the installation gap on both sides. It is usually 15 mm. For example, 800 + 30 * 2 + 15 * 2 \u003d 890 mm.

The height is calculated in a similar way. For a door without a threshold, it will be 2000 + 30 + 15 + 5 \u003d 2050, where 5 is the size of the mandatory gap at the bottom between the leaf and the floor for air exchange. If necessary, it can be increased up to 10 mm. And if the house is supplied with liquefied gas, then the gap should be at least 15-20 mm to ensure good ventilation. If your door has a sill, then the height of the opening is determined by adding the height of the threshold to the size of the canvas, the width of the box and the assembly seam.

Conversely, knowing the standards, it is easy to calculate the width of the door leaf for existing openings. For example, an opening of 900 mm requires an 800 mm door. It is calculated as follows: 900-15 * 2-30 * 2 \u003d 810 mm. And the excess 10 mm will be successfully hidden under the trims.

When calculating the dimensions, it is advisable to add the size of the gap, which is recommended to be left between the box and the door leaf. But since it is only 1-2 mm, then in rough calculations it can be ignored.

Double doors

The above values \u200b\u200bapply to single leaf designs. Double-leaf interior doors are often installed at the entrance to the living room. Their standard widths range from 1 to 1.4 meters. At the same time, double-leaf types of doors can have different or identical sizes of individual halves. For example, a product with a width of 1400 mm can consist of two parts 700 mm each or one 600, and the second 800 mm.

Doors with a hidden frame

Interior doors with a hidden frame have a number of advantages over conventional ones. But the price of such structures is much higher. The same applies to the requirements for the dimensions of the finished opening.

The dimensions of the opening must strictly comply with the requirements of the door manufacturer. The wall should be vertically even. A deviation of only 1 mm per meter of height is allowed. Wall thickness should not exceed 80 mm. Optimal value the installation gap width is 17-20 mm plus / minus 10 mm. In some models of products with a hidden box, deviations are not allowed at all. The gap under the web should ideally be 4.

Doors to order

The variety of dimensions of interior doors with a frame and fittings offered by manufacturers is very large. But, despite this, there are often situations when none of the manufactured sizes fits the existing opening. In this case, you can either correct it so that the width and height decrease or increase to the required ones, or order doors with non-standard parameters.

Make doors by individual order is much more expensive than buying ready-made products. But such a step will make it possible to embody non-standard ideas.

For interior decoration of residential premises great importance interior doors play. The door is a kind of "barrier" that allows you to delimit one room from another. In this case, the width of the door frame must be correctly selected so that there are no obstacles when a person moves, moving furniture and other objects.

When, the width can be selected in standard sizes or larger / smaller, taking into account the purpose of the room and the wishes of its owner. For houses and apartments, it is recommended to make room openings smaller than for the entrance to the dwelling.

The standard size for the width of the entrance door leaf is chosen more than 800 millimeters. Interior doors have a width of 600, 700, 800 millimeters.

Size dependency

Sometimes the owners deliberately expand the opening to 900 mm.

Tip: When designing and installing a passage in a room, it should be borne in mind that large furniture is very difficult to bring into a 600 mm wide passage. The optimal size is 800 millimeters. The same dimensions should be chosen for the bathroom, which will allow you to add washing machine and other large-sized equipment.

Standard dimensions are shown in the table:

The table shows that the canvas is selected at least 7 cm less than the doorway. But, in this case, the thickness of the door frame should also be taken into account.

So, for example, if the thickness is 30 millimeters, which corresponds to the minimum size, it is enough to increase the opening width by only 6 centimeters. But for veneered or telescopic boxes, this will not be enough. They are thicker, plus an extra gap for blowing foam.

Opening measurement

Height measurement

For those who like to do everything with their own hands and reduce the cost of work, a short instruction is offered that helps to correctly and quickly measure the doorway:

Measurement should be carried out on "bare" walls... For this, the door leaf and frame are removed before starting work.
The distance between walls is measured in several places: top, bottom and center... The smallest value is recorded.

Tip: If it was not possible to dismantle the elements, you need to measure the first or the size from the center of one of the platbands to the middle of the other. This will give approximate figures for the size of the opening.

Measuring width

The distance is measured from the lowest point of the floor to the top of the opening or the gap between the floor and the center of the casing is calculated if the box could not be removed.

Measurement scheme

The opening depth is equal to the wall width... Therefore, the width of each wall is measured: from both sides of the opening and from above, or the thickness of the door frame is measured, and the wall protruding beyond it is added to it, if any.

Size calculation

After taking measurements, you can correctly calculate the size of the door leaf.

This takes into account:

Door leaf height and width.
The thickness and width of the door frame.
Platband width.
If there is a threshold, its dimensions.

For example, a calculation is taken for a door leaf with dimensions:

Height - 2 meters.
Width - 80 centimeters.
The door frame thickness is 25 millimeters.

When calculating the dimensions, it is necessary to add to the width the thickness of the box on both sides. In addition, the calculation takes into account the mounting clearances on each side, approximately 15-20 millimeters.

In this case, the width will be equal to: 800 + 25 + 25 + 15 + 15 \u003d 880 millimeters. An example for counting is shown in the photo.

Width counting scheme

This width is practically perfect option for manufacturers of interior doors. The doors can be easily assembled into standard dimensions of openings in residential premises.

The height is calculated in the same way, taking into account the mounting clearances and the presence of a threshold. The height of the doorway will be: 2000 + 25 + 10 + 15 \u003d 2050 millimeters.

As a result, for a door leaf with dimensions of 2 x 0.8 meters, the opening in the wall is made 2.05 x 0.88.

What is the thickness of door frames? Usually the standard size is 75 millimeters. This must be taken into account when installing the door.

Otherwise, you will need to use a box expander or saw it along. In this case, problems may arise during the subsequent installation of platbands, which will lead to damage appearance doors.

To determine the parameters of the wall, you need to measure its thickness in three places from all sides. If the parameters around the perimeter of the doorway are the same, the order is made for products with non-standard dimensions. With different thicknesses at these points, the door frame is sawn or an extension is placed.

Watching the video in this article will allow you to correctly calculate the opening for installing the door leaf, taking into account the style, characteristics of materials, and operating conditions.

The purpose of the additional element

An additional element is a strip that is used to expand the beam of the used box for the opening.

It is used to close a section of a wall that is not hidden by a box beam. The width of the required addition is calculated by measuring the thickness of the wall in the door opening, and the width of the box beam is subtracted from the obtained value.

The standard width of the interior door frame is 7 centimeters. With a greater wall thickness, installation of additional elements is required. The exception is the use of "L" shaped platbands.

Tip: When purchasing doors, you must take into account the largest size of the wall thickness at the opening. Otherwise, the box will be smaller than the width of the wall. In this case, the platband will not fit tightly on the wall and box.

If such a defect has turned out, you need to use alabaster or gypsum mortar to cover the gap.

The width of the extension is acquired equal to or greater than the part of the wall to be closed. For example, if the wall is 12 centimeters wide, and the boxes are 8, you need to add at least 4.

Additional features

Before mounting the strips on the door frame, you should get acquainted with the advantages of installing them:

High speed of installation of the block for doors extended by addons.
There are no “wet” finishing processes that are unfavorable for wood.
A long period between next repairs.
Aesthetics that ensures integrity and beautiful view door structure.
Low price of slats.

Collected into a single whole, the three components of the expander-add, resemble the letter P, you can fix it:

Straight to the door frame.
To the wall, at the place of installation of the opening.
On a mounting bar located between the extrusions and vertical planes opening.

In the absence of a special mechanical load on the extras, only liquid nails can be used to fix it in a specially made recess. But more often galvanized self-tapping screws are used for installation.

Tip: If the fixing is performed from the front side, it is necessary to hide the fastener caps with mastics or plugs matched to the box's tone.

Types of add-ons

For home improvement, you can purchase doors:

With boxes in which a groove was previously selected on the outside for correct alignment with the extensions.

To do this, you can use chipboard or wood planks, one centimeter thick. The width of the slats is measured with a box mounted in the opening, which will be the basis of the structure. In this case, the element is nailed from the reverse side of the opening with small galvanized nails with a step of 20 to 35 centimeters. You can insert the strips into the recess, and then fix it in the opening of the box with glue.

Without groove with box bar. In this case, you can:

choose a groove with a machine with a special straight cutter yourself;
attach the add-ons to the timber of the box through pre-drilled through with self-tapping screws from the end of the element;

Tip: For attaching the expansion strips to the box, the diameter of the through holes is not the same along the entire length. First, the drill is taken with a diameter equal to the head of the screw, then by the size of its barrel.

additional elements are installed on the bars screwed to the wall with self-tapping screws. The first one is located 200 millimeters from the floor, and then in 60 centimeters increments;
addons with a box "sit" inside the plywood or drywall base;
a box beam without a groove is connected to the strips by installing a rail that runs from the outside of the opening along the alignment line;
a lath or plank made of plywood is fastened around the perimeter not in a continuous strip, but in separate segments.

A bar and additional strips are nailed to the rail. In this case, the central axis of the rail and the connection line must coincide or have a slight offset.

After assembly, the extreme line of the extensions is flush with the opening. Excess up to one millimeter is cut off with a plane, and then everything is closed with cash.

Installation of extensions

Usually, the upper bar, combined with the lintel, is superimposed on two vertical parts.

To calculate its length, it is necessary to add two thicknesses of additional racks to the lintel size. But you can also place a bar between them. In this case, the length of the lintel is chosen according to the width of the box, and the thickness of the upper bar is added to the heights of the left and right vertical elements.

Installation procedure:

Measurements are carried out with scrupulous accuracy according to the scheme that corresponds to the selected mounting method.

Tip: For right and left additions, the vertical dimension is measured separately. In this case, the inner line of the future plank should be measured by the box, and the outer one in the opening in fact.

The board is cut according to measurements and according to the construction scheme.
All three additional elements are attached to the assembled door frame.
When fastening the strips to a box not installed in the opening, it is installed together with them.
Mounting wedges are located between the wall and the door base and they align the device in the opening.
The blowing of the mounting gap with foam is carried out before installing the spacer wedges, between the box beam and the extensions.
Foaming of the entire space is performed in portions, at least in two steps. The adjustment of the hardening process is controlled while the foam hardens.
The work is completed by sealing the gap formed between wooden details and floor, and installation of platbands.

Correctly executed expansion of the door frame allows you to arrange any opening quickly and efficiently. This is especially important when it is difficult to find a standard ready-made design.

In order to bring the production of interior elements to a single model, standard dimensions of interior doors were introduced and approved at the state level. This greatly simplifies the selection of products when it is necessary to replace them. It is enough to make a correct measurement of the parameters of a typical opening and buy a suitable model.

If there are no problems with domestically produced products, then when buying an imported interior door, a difficult situation may arise, since there is a different standard in foreign countries. In addition, when buying alternative types of doors (double, sliding, hidden), you need to know some of their design features.

State standards

There are certain approved state standards (GOST), according to which domestic manufacturers produce interior interior elements. These are GOST 6629-88, as well as SNiPs 21-7, 21-8, 21-9, 21-10, 21-13. For ease of viewing, these data are summarized in a table that displays the most common standards:

If the choice fell on a product of imported origin, then the dimensions of the interior door can be checked for compliance with the European standards DIN 18100-18102, as well as DIN4172, indicating the dimensions of the opening in the light:

These dimensions must be taken into account if you plan to order, for example, an Italian door. Most likely, imported models will have non-standard dimensions that should be taken into account when bookmarking doorways during construction planning or overhaul.

For doorways in height exceeding 2000-2040 mm, its own standards have been developed, indicated in the table below.

In developing state standards takes into account the needs of the main segment of the population living in standard buildings. In the choice of typical models of one size or another, its functional purpose also plays an important role. In other words, the place in the apartment where this product will be located is important. In accordance with this requirement, the dimensions of the canvas, design features, and equipment with special fittings are selected.

The nuances of correct measurement of the opening

In some cases, it becomes necessary to independently measure the parameters for the purchase of an interior door. This happens if the house or apartment is located at a great distance from the manufacturing company, in another city or in another state. Self-measurement is also carried out in cases where there is no time to wait for the visit of the measurer or it is more convenient for the customer to take measurements on their own. Regardless of the reason, this event must be carried out as accurately as possible so that the selected model fits perfectly into the existing opening without the need to adjust it. This means that the height, width and thickness of the interior door leaf should be as close as possible to the corresponding parameters of the opening. To make a correct measurement, you should be guided by the following rules.

Determination of the width of the opening.

To do this, measure the distance between the walls at the narrowest point of the opening. If the wall becomes narrower closer to the door, then it is necessary to measure in this part. In the case of a uniform wall width without tapering, the location where the width is measured is not critical. If the dismantling of the old door has not yet been made, then the measured distance from the middle of one platband to the middle of the opposite platband is the width of the interior doors.

Determination of the height of the opening.

To determine the indicator of this dimension, it is required to measure the distance from the point of the finished floor to the lowest point of the upper part of the opening. If the doorway narrows closer to the hinges, then the measurement should be taken in this area. If the opening height is uniform, then the measurement location is not critical. The easiest way to measure is the old door, if it has not yet been dismantled. In this case, the height of the interior doors will be equal to the distance from the middle of the upper platband to the zero point of the finished floor.

Determination of the opening depth.

To do this, it will be necessary to measure the thickness of the wall in which the doorway is located. This will be the depth of the opening. Measurement should be made in three sections: top, middle and bottom on both walls. This scrupulous exercise is necessary in order to identify the widest spot in the wall. If the old door is not dismantled, then it is necessary to measure the dimensions of the box and the wall (thickness) if it protrudes beyond the box. For correct measurement of the three key dimensions, it is best to use the services of a professional. Possessing a body of knowledge, the installer will make an impeccable measurement and give practical advice on choosing a typical or non-standard interior door. We remind you that when ordering doors from Porta prima, the visit of the wizard to measure the dimensions and consultation on the choice of the door leaf are absolutely free.

Formulas for measuring door leaf

Often there is such a situation that it is required to make a doorway, and the choice of the model of the canvas has not yet been made. In this case, to measure the parameters of the opening, the following points should be taken into account:

door leaf dimensions (width, height, thickness);
box dimensions (thickness, width);
indicator of the width of the platbands.

For greater clarity, an example of calculating the dimensions of a doorway will be given.

Suppose that a standard size door leaf with the following dimensions will be used for installation:

Vdv - door leaf height - 2000 mm;
Шдв - standard width of an interior door - 70 0 mm.

With such parameters of the interior product, a box will be installed, the thickness of which (Tc) will be 30 mm. In this case, the size of the mounting gap (Mz) will be equal to 10 mm, and the value of the door block (Bd) will be 20 mm. With these standard values, the threshold height (Bp) will be 20 mm.

Formula for calculating the width of the opening of the future door:

Opening W \u003d Shdv + 2 × Tk + Mz + 2 × Bd \u003d 700 + 2 × 30 + 10 + 2 × 20 \u003d 810 mm.

The opening height is calculated using the following expression:

In the opening \u003d Vdv + Vp + 2 × Tk \u003d 2000 + 20 + 2 × 30 \u003d 2080 mm.

Therefore, for an interior door leaf with dimensions of 2000 × 700 mm, it will be necessary to make a doorway of 2080 × 810 mm.

The door frame is manufactured according to the standard of the opening depth of 7.5 mm. If the thickness of the door leaf of the interior door does not correspond to this indicator, it is necessary either to order a box according to individual dimensions, or to use additional elements in the design. Therefore, it is recommended to make calculations in advance.

How to calculate if the door fits into the opening?

A common situation is when standard door to the existing opening. Usually, a good clue for choosing is the labeling of door products, which indicates the main dimensions.

At this stage, doubts may arise as to whether the product will fit and whether there will be additional difficulties in its installation.

To dispel doubts, you need to reason as follows:

Let's say we have a doorway of 900 × 2040 mm, which meets the standard.
We calculate the width: indicator standard width we fold 800 mm canvases with a box thickness (on both sides) and design intervals of 15 mm. Note that there is an interval to the left and right of the door, so you need to multiply it by two. When calculating, we get 880 mm.
We calculate the height in a similar way. A door leaf height of 2000 mm is added to the 25 mm box thickness and 15 mm top mounting distance. We get the value 2040 mm.

Therefore, an interior door with a standard size of 800 × 2000 mm will ideally fit into a typical opening with dimensions of 900 × 2040 mm. This once again proves the need to create state standards in the construction industry. You can safely buy a typical product without being tormented by doubts whether it will fit.

What to do if the door is chosen incorrectly?

However, there are situations when the purchased canvas with the box was not chosen accurately. When the return of the purchase is impossible for an objective reason, you can use some construction tricks:

when only a few millimeters in the width or height of the doorway are missing, you can carefully cut a wider hole in the wall;
if the box is narrower than the thickness of the wall, it is recommended to use an extension that will cover the prominent area of \u200b\u200bthe thickness of the wall;
if the thickness of the box is much narrower than the dimensions of the doorway, then along the perimeter of the box (with the exception of the bottom) they are drawn into an even slope;
if the listed methods are unacceptable, it is recommended to order doors according to individual non-standard parameters.

At Porta prima you can buy high-quality standard interior doors or order individual design according to your project. Thousands of Muscovites have appreciated the wide assortment, convenient service and unsurpassed high consumer characteristics of the products of our factory. The prices are reasonable and correspond to the high quality of the interior doors.

The door blocks consist of two parts - a leaf and a frame. Most of the produced door blocks have standard door leaf sizes from 60 to 90 cm. The dimensions of the door frames, regardless of the dimensions of the door leaf, exceed its dimensions by a certain amount. But this figure is not a standard for all models of door frames and may differ to a lesser extent in lighter door frames.

How to measure thickness?

First of all, we will define the terms and agree on what exactly is meant by the thickness of the door frame. Since this size is often confused with the depth of the box, let's clarify right away: take a look at the image below. The thickness of the door frame is the distance equal to the difference between the width of the door frame and the width of the door leaf divided in two. The depth on the diagram is labeled as "The size of the wall thickness in the opening" and equals 5-7 cm. The minimum depth for standard door frames is 65 mm. The rest of the size options are already non-standard dimensions and to order, check their availability at the place of purchase.

Having decided on the concept of thickness, we will calculate it for standard door blocks. For generally recognized manufacturers in classic door models, the dimensions of the door frame more sizes canvases by 70 mm both in width and in height, if the box is with a threshold. So, for example, for a door leaf 800 mm wide, the frame width will be 870 mm. By these dimensions, it is easy to find out what the standard thickness of the door frame of interior doors is. To do this, we will use the formula:

Tk \u003d (Shk - Shp) / 2

Where Tk is the thickness of the door frame, Shk is the width of the box, Shp is the width of the leaf

Using the example of a door leaf with a width of 800 mm, the calculation will look like this:

Tk \u003d (870 mm - 800 mm) / 2 \u003d 35 mm

The resulting value will be standard thickness of the door frame of interior doors,it equal to 35 mm.

There are also lightweight door frames that differ from standard sizes. The thickness of such a box will be less than 35 mm and before buying, check with the seller which door you are buying. Recently, door manufacturers have begun to produce more lightweight boxes and there is a possibility that when buying, you can accidentally choose just such a model. The thickness of the timber (or MDF) used for lightweight boxes is 25 mm.

Types of door frames on video

Why else do you need to know the thickness of the box?

It is no coincidence that the thickness of the door frame is 3.5 cm. As we already wrote, the dimensions doorway also calculated depending on the dimensions of the door leaf and in standard interior openings they are 10 cm wider than the width of the canvas. Thus, we get the distance from the leaf to the doorway equal to 5 cm.There just fit 3.5 cm of the thickness of the box and 1.5 cm gap for fixing the door frame in the wall using polyurethane foam.

Installation door block (canvas + box) occurs not only on polyurethane foam. Although each method involves its use, the technologies differ in the type of additional fasteners used during installation. Most often, simple wooden spacers or pegs are used, which are inserted into the space between the box and the opening. With their help, the block in the opening is aligned according to the level: each peg is driven tightly so that the door frame does not deform, but the entire block is tightly held in the opening. When it is firmly fixed with spacers, using a special gun, polyurethane foam is applied to the voids. It is also important to install horizontal spacers inside the box so that the foam does not deform the box when it expands.

Thus, we found out that the standard thickness of the door frame of the interior door is 3.5 cm. It is also important to remember that in last years manufacturers are increasingly releasing non-standard boxes. They are also called lightweight and are used in cases where there is a need to install a wider canvas in a small doorway.

During a major renovation, every homeowner will inevitably face the question of choosing interior doors. Pick up the best option door leaf design that matches the interior of the room is not difficult - there are many interesting offers from manufacturers on the market. When choosing an interior door, attention should be paid to the dimensions of the door leaf together with the frame. As a guideline, you should use the GOST standard, which greatly simplifies both the choice of design and its subsequent installation.

Standard dimensions of interior door frames: width, height and thickness

The GOST standard strictly defines the dimensions that the door frame must correspond to. Sizes may vary depending on functional purpose the room for which the interior door is selected.

Width standard box the interior door for living rooms is 80 cm. In this case, the standard thickness of such a doorway into which the box is inserted is from 7 to 20 cm (depending on the type of material from which the house is built).
The width of the door frame of the interior door for the bathroom is 60 cm.The standard height of the doorway is from 190 to 200 cm.
The standard width of a modern interior door for a kitchen is 70 cm, and the thickness of the doorway in this case is 7 cm.The height of the opening into which the door frame is inserted is also standard and it is 200 cm.

This standard is universal. These dimensions are taken into account by designers when choosing door designs. different types, including if the planned interior door is not a swing, but a sliding type.

Dimensions of interior doors with a frame: width and height for the living room

The living room is the hallmark of the house, therefore the interior door intended for this room is chosen especially carefully. Typically, the dimensions of the doorway that meet the standards are slightly wider in this room from openings to other areas of the house. The same standard is used in the construction of apartment buildings. As a rule, the height of such an opening is from 201 to 205 cm with minor possible deviations. The width that the box must match varies from 128 cm to 160 cm.In most cases, a double-leaf interior door is used to equip such a doorway, the width of each leaf of which is 60 cm.When choosing the size of the leaves, the width of the box and the individual preferences of the customer are taken into account ... For example, an interior door can consist of two independent leaves, the dimensions of which are exactly the same, for example, 60 cm. And you can order such options in which the door leaves different sizes (60 cm and 80 cm). It should be noted that this block width meets the standards.

The door frame to the living room or to any other room should be slightly smaller than the opening in which it will be mounted. If the width of the opening is standard, then in this case the door frame will be 10-15 mm less from the walls of the opening. This is necessary to perform a high-quality door installation. It should be noted that regardless of the material from which it is directly made door structure (array, MDF), the door frame, namely its parameters, remain within the limits defined by GOST.

How to remove the dimensions of interior doors with a frame - width, height and thickness

In order to determine as accurately as possible what width of the door frame corresponds to a certain doorway, it is necessary to correctly measure the dimensions. To determine whether the width (thickness) of the doorway is standard, you should use a tape measure and follow the basic recommendations:

First of all, dismantled old box, and the opening itself is being prepared for the removal of the necessary parameters - the remnants of the plaster and polyurethane foam are removed until the doorway acquires a clear outline.
What is the width of the opening is determined by removing the parameters at three different points - at the bottom, in the middle and at the top.
The length is measured from the top of the opening to the floor. Experienced craftsmen, in order to avoid parameter mismatch, it is recommended to take measurements of height in several places.
The thickness of the wall of the opening, into which the interior door from MDF or solid wood will be mounted, is also determined on the basis of taking several measurements - on both sides and the upper part of the opening in which the box will be fixed.

If the width of the doorway to be equipped does not correspond to the standard parameters, in accordance with which the selected interior door is made, then in this case the deficiencies must be eliminated. Depending on the situation, a decision is made to adjust the opening for the installation of an interior door. So, for example, if the width of the opening does not correspond to the parameters of the box, then in this case the walls can be cut (if it is necessary to increase the width) or the opening can be reduced using an additional layer of plaster or foam. If the interior door is narrower than the thickness of the wall, in this case, you can adjust the thickness of the wall with a puncher in accordance with the required parameters.
