What width are the door frames. Door frames for interior doors: dimensions and installation

Replacing doors during the event is a very responsible business. It is important not just to pick it up, it must fit into the opening. Adjustment of dimensions is often impossible without disturbing the structure of the coating. The risk in this case is very expensive. Therefore, when choosing, you need to take into account not only the design, but also the standard dimensions of interior doors, typical marking methods of opening, and prepare as much as possible before going to the shopping center.

The purpose of the interior products differs from those designed to protect the home from the penetration of strangers. First of all, they should be highly functional and provide comfort in the premises. The requirements for different rooms are different, but you can still highlight the main criteria:

• Protection of the premises from unwanted visits. For example, you need to create confidence that no one will accidentally interfere during the adoption of procedures. In addition, protection is needed from increased noise, light, odors from the kitchen or drafts;
• division of space- this is necessary to delimit the premises into separate zones and organize the area according to its purpose;
• - canvases must correspond to the general design of the premises.

Structures can be glazed or sheathed tightly. By the way of opening - cassette. The main selection criterion is that the canvases must completely cover the entrance.

Dimensions of interior doors according to GOST

The state standard approved the dimensions of the interior structures. In this case, several parameters must be taken into account at the same time: length, width and thickness of doorways. All manufacturers adhere to certain standards. If necessary, it is possible to manufacture structures according to individual measurements, but this will not be cheap for the customer.

Here are the main standard dimensions of interior doors with a frame for a door leaf thickness of 44 mm:

You should know this! Standard parameters allow you to select and install the structure as accurately as possible. However, its functionality will not be impaired.

How to correctly measure the opening

If it is not possible to invite a measurer, you need to measure all dimensions yourself. To do this, you will need a tape measure, a pencil, and a piece of paper.

• Measurement of the width must be performed at the top and bottom at a distance of 20 centimeters from the upper and lower borders and in the middle;
• the height is measured in two places: from the floor surface to the upper boundary. If there is a sill, it should be taken into account when taking measurements;
• measuring the thickness of the door frame of the interior door. Moreover, if it is more than 100 mm, it will be necessary to additionally install additional elements in the form of slopes.

The gap between the box and the wall should be 15 mm. After installing the structure, it is filled with polyurethane foam.

If you plan to install non-standard structures, for example, in the form of an arch, you need to contact the professionals. It is quite difficult to make such measurements correctly. You can draw a project on paper and give it to manufacturers.

Calculation of the proportionality of the box to the opening

If you do not have a table of proportions at hand, you can independently calculate the necessary parameters. To do this, add the width of the box and the thickness of the mounting gap on both sides to the width of the web.

• The standard width of the door frame is 25 mm;
• the recommended gap on each side is 15 mm.

Let's calculate the parameters of the opening width for a leaf with a width of 550 mm:

550 + 25 × 2 + 15 × 2 = 630 mm.

To calculate the size of the opening for interior doors in height, you need to take into account:

• the distance from the floor surface to the sash is 10 mm;
• the thickness of the box is 25 mm;
• gap 15 mm.

Height parameters without a sill will be calculated as follows:

2000 + 25 + 15 + 1 = 2031 mm.

To install a box with a threshold, instead of an indent to the floor surface, you need to add the height of the threshold, and take into account the way it is fastened: with foam or screws.

Building dimensions do not always fit into these formulas. In case of discrepancies, you can use the following tips:

• if a few millimeters of the width of the opening are missing, you need to slightly expand it manually;
• if the box is much narrower than recommended by building codes, you should select the appropriate dimensions for interior doors, they will close the free wall;
• if the product is installed in a load-bearing wall, its thickness may exceed the thickness of the box. For such a case, slopes are installed.

If none of the proposed options is suitable, you should make a custom-made unit.

Corridor Item Definitions

When choosing a product for a room, you need to take into account the dimensions of the openings. They must differ from the parameters of the flaps. You cannot rely on standards, you must measure yourself.

The standard height of doorways in the corridor is 2.01 ÷ 2.05 m. The width can vary from 1.28 ÷ 1.6 m.

In order to select a product according to such parameters, you can stop at a double-leaf structure with the same canvases of 60 cm, or different widths of 0.6 + 0.8 or 0.6 + 0.9 m.The total width allows you to install them in the opening 1 , 6 m.

Product marking

There is a marking of products in accordance with GOST; in practice, manufacturers make their own adjustments and designations. Let's first consider the generally accepted norms.

The height and width of the structure are indicated in decimetres.

You can find the individual manufacturer's markings with other designations for the size of interior double-leaf doors, indicating the material of manufacture and the name of the product. Dimensions can be indicated in centimeters.

Standard dimensions of hinged interior doors with a frame

Swing structures are installed in wide openings. Most often - in the living room. They attract attention and become the centerpiece and decoration of the room. It is important to correctly determine the size of interior doors with a box, since mistakes will immediately catch your eye.

Canvas dimensions

In the apartments of buildings of the last century, swing doors with a wing width of 65 cm and a construction height of 230 cm were most often used. Currently, manufacturers have expanded the production of models and offer door frames of the following parameters.

Door frame dimensions

Swing door frames are made of U-shaped design without sills. This is enough to completely fix the product around the perimeter. As in conventional models, when calculating the parameters, it is necessary to leave a gap between the box and the opening.

In the manufacture of the door frame, different materials are used. The width can be in the range of 15-40 mm, the optimal size is considered to be a width of 30-35 mm.

Dimensions of doorways

Manufacturers often indicate the standard dimensions of doorways along with the product labeling.

You can determine the width using the formula:

double leaf width + double frame width + double gap

The frame width is generally 30 mm, leaving 15 mm on each side for the gap width.

To determine the height without a threshold, the distance from the floor surface to the canvas should be taken into account about 5 ÷ 20 mm:

sash height + frame width + gap + height from the floor surface

When installing the nut, the calculation of the height is the same as the determination of the width.

Blade thickness

This is the third characteristic of interior designs. The strength of the entire structure and sound insulation depend on it. The standard thickness of the canvases is 40 mm. Manufacturers also offer thinner canvases of 20, 30, 36, 38 mm.

Products with a parameter of 50 mm can be made by individual order.

Interior doors of non-standard sizes

Free layouts of apartments and the construction of private houses imply a non-standard approach to the design of premises. Often used for constructions from. For such planning, the standard parameters of door products may not be suitable.

On an individual order, you can make not only canvases of non-standard parameters, but also of an unusual design. In this case, it is important to take into account the thickness of the material, since drywall is limited in the perceived loads.

If you plan to manufacture a canvas of a non-standard size, it is important to take into account some features and limitations.

• Reducing the height of the product is not recommended. Increased heights can be installed in rooms with high ceilings;
• when changing the width, it is important to take into account the uniformity of the load distribution. If the opening is more than 2 meters, additional support elements should be installed in the middle of the structure.

As a non-standard technique, you can change the width of one sash to a third or half of the standard width. This model is usually called one and a half.

This is important to know! Manufacturing custom-made structures will increase the cost by 30 ÷ 40%.

Standard sizes of interior doors: main types and assortment

The modern market is filled with a variety of products. You can pick up quite budget models or luxury exclusive samples in different colors and designs. When choosing, you should take into account the basic design of the room.

The main materials for the manufacture of products:

Photo	Material
	Glass
	Wood
	, or MDF
	Pvc

Classification of models by opening method

Manufacturers offer samples with a hidden box. To install such structures, certain requirements must be met:

• wall thickness should not exceed 80 mm;
• the parameters of the opening must comply with the manufacturer's recommendations, the vertical deviation is no more than 1 millimeter.

You can pick up designs with a non-standard opening method. They save space, in addition, an attractive appearance will be a bright accent in the design.

• Swing models with the classic way of opening, they can be left- and right-handed, while the hinges are mounted on the opposite side.

• Sliding- significantly save space. They have one or two canvases moving along the floor surface along special guides.

• Harmonic- several canvases are folded in the form of an accordion, for their installation, wide openings are needed.

• Swinging are made of 1 ÷ 2 canvases, the mechanism allows you to open the canvases both inside and outside the room.

Conclusion

Interior doors complete the interior design. A high-quality installation depends primarily on correctly performed measurements and calculations. When choosing a product, you need to take into account many parameters: material, weight and dimensions of the structure. Manufacturers offer a wide range of models that fit both conventional and non-standard openings. If desired, you can make an individual design of the structures.

In order to know the standard dimensions of interior doors with a frame, you need to study the generally accepted standards. In addition, there is a special table with precise indicators. It is necessary when ordering, purchasing, and then installing a door leaf indoors. Each manufacturer has its own method of creating doors, but they must adhere to regulations. Below are the GOSTs, on the basis of which standard doors are produced, tables with dimensions and possible markings.

Door size standards

The GOST parameters must be taken into account not only when creating a door or frame, but also when calculating the opening. GOST standards related to interior doors:

• Opening to the kitchen - GOST 702007;
• For toilet and bathroom - GOST 55-60190-2005-7;
• Bedroom - GOST 802007-20;
• Living room - GOST 2007-20.

The latter deals with double doors and an opening that must comply with the standard. Most often, when installation is carried out without the participation of a specialist, the norms prescribed in these documents are not taken into account. The construction market offers a lot of modern models of door leaves, but most often their size indicators have standard numbers: 200 cm, width 60-80 centimeters. The thickness of the box varies from 15 mm to 45 mm, but if you make an individual order at the factory or it is a self-made production, then the thickness indicators may differ.

If you do not comply with GOST standards for door sizes, then this may entail the need to expand the opening.

Common parameters

The GOST states that the parameters of the box must correspond to the dimensions of the canvas, taking into account the gaps necessary for the installation of the structure. If the manufacturer has created the model correctly, the indicators will be as follows:

The proportionality of the frame and the thickness of the wall opening must be observed. If a smaller canvas is purchased, it does not matter, you can use such a device as an add-on. It will close the gap tightly and hide the miscalculation.

The standard size of the door frame, which is spelled out in regulatory enactments, for a door to a room in height should be 190-200 cm. If the doorway is two meters, then the door itself is ordered a few centimeters less. If this is not taken into account, then it will not be able to freely close and open.

The standard thickness of the canvas is 4.5 cm. The width, as a rule, depends on the dimensions of the room itself.

Double doors have their own characteristics. Wide openings can be present at the entrance to any room, but they are most often found in living rooms. GOST informs that the width of these canvases should vary from 120 to 150 cm. These parameters contain functionality and ease of use.

The largest sizes of door frames used by manufacturers in Russia for interior doors are 90 cm wide. As a rule, they are installed in industrial production, in offices or in large country houses. The opening should be proportional to the room itself. If the room is small, then a massive door leaf will look ridiculous or cumbersome. It is worth noting that this parameter was used in the Soviet "Stalinist" buildings, since the living area is very spacious. Such doors are produced in small quantities, and not very large enterprises make them exclusively to order.

Marking

The dimensions of the door directly depend on the dimensions of the opening. Marking even for absolutely identical doors may differ, but all wooden door structures must comply with GOST 6629-88. It states that these parameters are used for the manufacture of interior doors for residential and public facilities. The type of product is marked with the letter "P", which means a panel, and the letter "D" indicates that the products are prefabricated. There is a difference in the type of cloth. If there is an abbreviation "O" - then the product is glazed, and if the letter "U" - then the glass is made with a solid filling.

You can also find marking in the form of the letter "P", which means that the product is with a sill or "L", telling the buyer that the door is left-handed.

Sizes of canvas and box

According to SNiP, the standard size of an interior door with a frame is divided into several separate indicators, which are reflected in the table:

If we talk about the European standard, then the ratio will be as follows:

The Russian width of the canvas for the kitchen will be 70 cm, for the toilet or bath - 60 cm, and for the room - 90 cm.

Measurement formulas

To take measurements yourself, it is not necessary to call a specialist for this. First, you need to take into account such nuances as:

• Height;
• Width;
• Thickness;
• Platband parameters.

If the height of the canvas is 200 cm, the width is 70 cm, the box is 3 cm thick, then the gap should be 1 cm, the door block - 2 cm, and the height of the threshold - 2 cm.To make calculations, these numbers must be substituted under the following formula: Sh dv + 2 * T k + Mz + 2 * Bd. The result will be: 70 + 2 * 3 + 1 + 2 * 2 = 81cm. If you want to find the height of the doorway with the same parameters, then the formula is as follows: B dv + B n + 2 * T, you get: 200 + 2 + 2 * 3 = 208. As a result, it turns out that for a door with parameters 200 by 70, a doorway of 208 by 81 is required.

The standard opening depth is 7.5 cm, so manufacturers create door frames for this value. If the door has already been purchased, but at the same time it turned out to be less than required, you can find a way out - to buy additional elements.

Algorithm for measuring the size of the doorway

The measurement process itself is no less important. Experts assure that it is in this work that mistakes are most often made, and, accordingly, subsequent calculations will be incorrect. In order for the door frame in a residential or public space for interior doors to be measured correctly, and the dimensions made it possible to make correct calculations, the following sequence of actions should be followed:

• First, the height changes from the floor itself to the top of the opening. If you are sure that it is not even, you should take measurements in the middle;
• Width is measured from the middle of the left to the middle of the right casing;
• The depth can only be found out by taking a complex measurement: at the top, middle and bottom to find the widest value.

Standard table for calculating doorways:

If a person lives in an apartment or house with a standard layout, then the indicators of his measurements will be identical to those indicated in the table.

Box and clearances

When buying a door leaf, you need to pay attention to the dimensions of the interior doors, which are indicated on the package. There should be an explanation that the dimensions are written with the box. As a rule, they should be increased by 10-15 cm when comparing with the dimensions of the door. We must not forget that a gap should be left between the wall and the mounting strip, therefore the parameters of the panel should be less than the characteristics of the frame. Also, experts recommend purchasing a structure along with cashing, frame and fittings.

For the manufacture of boxes, manufacturers use bars, which can also vary in size. Average width: 1.5-4.0 cm, but the standard indicator is 3.0-3.5 cm. Only with the latter indicators can we expect that the structure is strong enough and will last for many years. It is important to pay attention to the thickness of the box. It is best if it matches the parameters of the wall. For brick buildings, this is 7.5 cm, and for wood - 10 cm.

Conclusion

When it comes to standard premises, the applicant should not have any difficulties in choosing the design of the door and during its installation. This applies more to apartments. When a person builds a house on his own according to an individual design, then the doors will have to be made to order, having previously taken measurements. If a person is afraid to make a mistake in measurements, then it is better to entrust this work to specialists.

Sooner or later, every apartment owner has to deal with the problem of overhaul, during which it will be necessary to replace door frames for interior doors. The task of installing a door frame in the doorway does not require possession of any specific carpentry skills, the main thing is attention and accuracy in work.

How to put a door frame, sequence of operations

Any work on replacing door frames begins with a study of the width and condition of the walls, the old loot and the opening. Often, the walls themselves, brick and concrete require cosmetic repairs, finishing and restoration of plaster, therefore, before assembling the door frame, it is necessary to remove the platbands and restore the integrity of the brickwork.

The very procedure for installing the door frame of an interior door is simple, and its implementation fits into a few simple operations:

• They remove the door, cut the loot in width with a hacksaw and carefully disassemble the old box, freeing the doorway;
• Measure the width of the doorway in at least four locations. If you plan to install a new door with a larger width, you will need to trim the vertical walls of the opening using a grinder and a punch. But this must be done extremely carefully so as not to break the brickwork;
• Measure the exact width and height of the new door. Measure the required dimensions of the doorway on the wall, taking into account the allowances for the thickness of the boards and the width of the gaps. The total opening width will be defined as the width of the door frame of the interior door plus 25 mm per side for mounting elements and foam;
• Mark the timber or board purchased for assembling the box, saw down the joints on the jambs, sew them on the self-tapping screws and try on the new door. Install the frame in the doorway, check the width and fix with screws and foam.

Advice! If you are not completely confident in your skills and an accurate understanding of how to install and fix the door frame, you can participate in the process of replacing the door frame with neighbors or friends, make a trial drink with your own hands, or watch a video, for example:

Which door frame option to choose

Prefabricated interior doors are often produced and sold with a standard width door frame kit disassembled. This option saves you from having to select the width of the box with your own hands, but there is no guarantee that the door frame is assembled correctly. Therefore, often the door of the required width is bought separately, and the board or MDF-MDF boards separately. Standard sizes of door frames - thickness and width of doors are shown in the table:

In addition, when choosing the size of the material for building a loot, it is necessary to take into account that the thickness of the door frame of the interior door is a standard value, but the width of the walls, even within the same apartment, can vary greatly. Therefore, for each interior door, you have to check the width of the doorway, draw up your passport with the dimensions and, if necessary, buy additional elements that allow you to expand the width of the door to the width of the walls.

To make a loot or a door frame of the required width, the following are most often used:

1. A ready-made profile from pressed fiberboard or MDF;
2. Corrugated pine board, suitable for the width, the surface of which is sanded to the quality of a laminate or covered with a polymer film.

If you have a choice, use coniferous profiled boards to assemble the door frame. This material has good workability, high strength, and does not pick up moisture like compressed paper and wood fiber materials.

For your information! A self-tapping screw screwed into the wood according to the rules will provide 100% of the strength of the connection, a similar fastener for pressed paper provides 30% of the calculated strength of the fastener.

In addition, a pine box will allow you to install heavier doors, for example, MDF, glass or solid wood. Fiber-based materials are only suitable for the lightest cardboard structures.

We put a door frame of standard width

Before cutting the vertical and horizontal elements of the box, it is necessary to determine the method of connecting the boards or timber into one structure. The most durable and easiest to manufacture is a thorn-groove joint. To do this, cut out two blanks of vertical racks - hinged and false parts. To the calculated length of the rack, you must add twice the thickness of the workpiece. In a similar way, the lintel is marked and cut out. On the lintel, with the help of a drill and a hacksaw, spikes are cut out from both ends, on vertical racks along the finished spikes, the lintels are marked and cut in the form of grooves. The nut is made in the same way.

If the width of the wall is greater than the thickness of the box, the boards are built up with additional elements, as in the diagram.

If the width of the opening in the wall is greater than the size of the box, in this case, an additional piece of timber is sewn onto the outer part of the patch, from the side of the hinged or hinged beam, as in the diagram. If the width of the opening is too large, the false part of the box is complemented in a similar way.

On the side, the trays are made on the door leaf laid in a horizontal position. After adjusting all parts and aligning the corners of the box, the joints are glued and connected with carpentry screws. To preserve the obtained geometry of the trap, the structure is sheathed with wooden strips - spacers, carefully removed from the door leaf and installed in the doorway.

Door frame installation

The trap will be positioned correctly if each movement or alignment is controlled with a building level. Due to the low rigidity, the structure "plays", therefore, immediately after installation, the opening of the box is slightly wedged with thin wooden blocks. To prevent extrusion of the sidewalls and the ceiling beam into the frame, use a pair of wooden spacers, as in the photo.

The box is pre-aligned according to the readings of the level gauge and notches are made on the walls, in the future they will help to quickly restore the previous position of the loot. We fix the wooden structure to the wall using long self-tapping screws; for heavy doors, anchors can be used.

On the lintel and vertical racks, we drill two thin holes with an electric drill, 0.5 mm less than the diameter of the self-tapping screw. Next, we remove the trash, punch holes along the drill marks on the walls and install dowels for 6 mm self-tapping screws.

We return the tray to its place, insert the self-tapping screws and wrap it 10-15 mm. After that, using a level, we restore the correct position of the box and screw the fasteners to the full length. Blow out the gap between the timber and the wall with foam.

Conclusion

Before the foam hardens, it is necessary to check the position of the door frame again according to the building level data, if necessary, carefully tap it in the place of deviation. After the polyurethane foam picks up half the rigidity, you need to tighten the screws again and close the caps with decorative caps. After installing the awnings, we fasten the platbands.

If it is necessary to install an interior door, you initially need to purchase a canvas with a box after that. In stores you can find both non-standard and classic models. You need to know what additional dimensions a doorway for a door of 80 cm has, so as not to be mistaken when purchasing an entrance group.

Every master should be able to calculate the size of the opening for an interior door 2000 by 800. Canvases made of MDF, chipboard, fiberboard, solid wood have a running width of 60, 70 and 80 cm (single-leaf structures).

In multi-storey panel houses built in the Soviet Union, passages from 80 to 100 cm wide are provided. This is a classic version. Standard characteristics are dimensions approved at the state level and supported by GOSTs. The advantages of standard dimensions:

1. A wide variety of models. You can find the product you need in a specialist store.
2. Low cost and good quality.
3. Easy to install.

If it is necessary to purchase a pass-through system, the consumer asks about what kind of opening is needed for an interior door of 80 cm, so as not to carry out additional work during installation. In order to avoid mistakes, it is necessary, taking into account the technological clearances and dimensions of the purchased product with the box.

How to calculate everything?

Before you start calculating the dimensions of the passage for the interior structure, you need to take into account the following parameters:

1. Box width.
2. Threshold, if any.
3. Additional decorative elements.
4. The thickness of the box.
5. Height and width of the web.

For a door of 80 cm, it is better to calculate without a threshold. Example: a canvas with a size of 2000x800 mm, the thickness of the box is 25 mm. The calculation begins with the summation of the thickness of the box and the width of the web. 25 mm must be taken twice, since the box is installed on both sides of the passage. To the resulting amount, add 20-40 mm. This is the technological gap required for installation work. You should get 870-890 mm - this is the width of the passage for the model at 80 cm.

Important! It is necessary to pay attention to the material used for the manufacture of the interior door. When choosing an array, the thickness of the box will be greater (+20 mm).

The threshold plays a role in calculating the height of the web. The height is calculated in the same way. The thickness of the box is taken once and if a threshold is present, its height is added.

Before starting the installation of the product, it is required to inspect the condition of the walls and correct the shortcomings. Entrance structures should not be fixed on wobbly elements (plasterboard structures, pieces of wood covered with cement). When installing the compartment, the width should be greater than the aisle.

Table of standard sizes of openings

To facilitate calculations, it is worth using a ready-made table of standard sizes:

Here are the parameters of the passages and entrance groups, which can be purchased in hardware stores. Moreover, the range of such products is large. Installation can be done independently if you follow the instructions. If you do not have sufficient knowledge and experience, then entrust the measurements and the installation process to specialists.

Conclusion

It is recommended to take measurements with precise instruments, for example, a laser tape measure. In this case, it is worth considering the errors of the instrument. The amount of additional costs and the amount of work will depend on the correct calculation. If the dimensions were determined correctly, then the installation of the structure will not cause difficulties.

Before installing the door leaf, it is required to correctly measure the opening and the box. The utmost precision in sizing guarantees the long-term performance of the product.

Finding the right frame size

The determination of the parameters of the frame structure for the door leaf begins with the calculation of the dimensions of the passage in the wall and the study of GOST.

Measurement of the doorway according to the formula

To make sure that the door frame fits perfectly into the opening in width, the simple formula W p = W dv + 2 * T k + M z * 2 + W n + W z will help, where W p is the width of the opening, W d is the width of the door cloth, T k is the thickness of the box, M z is the mounting gap, Z p is the gap for the hinges, and Z z is the gap for the lock.

According to the formula, a door 800 mm wide with a frame 30 mm thick, an assembly gap of 10 mm, a hinge clearance of 2 mm and a lock clearance of 4 mm should be placed in an opening almost 89 cm wide (80 + 2 * 3 + 1 * 2 +0.2 + 0.4 = 88.6 cm).

The size of the doorway includes the dimensions of the door leaf and door frame

And to get rid of doubts whether the box is suitable for the passage into the room through the wall in height, the formula B p = B dv + P p + 1 cm + T k + M Sv + M Zn will help, where B p is the height of the passage into the room, B dv is the height of the purchased door, P p is the distance from the floor to the threshold, 1 cm is the standard for the size of the gap between the wall and the door frame (box) in the upper area of ​​the opening, T k is the thickness of the door frame (3–10 cm), M Sv - the installation gap between the frame structure and the door leaf at the top, and М Зн - the installation gap between the frame structure and the threshold at the bottom.

It turns out that doors with a format of 200x90 cm with a block 5 cm thick and a threshold 3 cm high must be inserted into an opening with a height of at least 210 cm (200 cm + 3 cm + 1 cm + 5 cm + 3 mm + 5 mm = 209.8 cm).

The dependence of the door frame on the opening

As indicated in GOST 6629–88, the box of interior doors should be 5–7 cm wider than the width of a standard door leaf. And the block of doors at the entrance to the house is recommended to be made up to 12 cm wide, because such an entrance group has the function of an evacuation exit.

The height difference between the two elements of the door block can be from 43 mm. This means that a door with dimensions 600x1900 mm can be mounted in a box with parameters 665x1943 mm, inserted into an opening 685 mm wide and 1955 mm high.

The dimensions of the door block increase as the frame structure and platbands are added to the canvas

Table: Correspondence of the dimensions of the box to the door leaf and the opening

Video: calculating the doorway

Standard door frame dimensions

Manufacturers of door frames are guided by the dimensions of the door leaf and most often produce products with a width:

• 67 cm;
• 77 cm;
• 87 cm.

The door frame stick has a size of 30–35 mm. These millimeters are added to the width of the door on each side. Therefore, it turns out that the frame usually increases the size of the door leaf by 7 cm.

The door frame increases the door width by at least 6-7 cm

The height of the door frame is determined by the height of the door leaf. If the second indicator is 2000 mm, then the first can be 2070 mm.

The door frame adds 6-7 cm to the door height

Appointment of the door depending on the size

The dimensions of the door are reflected not only on the dimensions of the box, but also on the terms of use of the product. For example, a particularly wide door leaf always leads into the living room.
