Dimensions of metal entrance doors: standards and tips. Dimensions of metal doors: what is important to know

Before installing metal entrance doors, you need to measure their dimensions along with the frame, and if the parameters are standard, then choosing a suitable model will not be difficult, but if not, then you will either have to purchase a custom-made product or look for non-standard solutions during installation. As the saying goes: “Measure twice, cut once.” If previously the front door was only wooden, and metal was used most often in warehouses, today the second option is more popular due to its practicality and ease of operation.

Types of iron doors

In steel structures, the door leaf is rarely sold separately; usually the frame is included.
That’s why the dimensions of metal entrance doors with frames are written everywhere. In Soviet times, iron doors were the province of warehouses and special institutions, but now they are installed everywhere. Such high popularity gave rise to a lot of new models, as a result, in addition to the sizes of iron doors with a frame, classifications appeared according to purpose and design features. First, let's look at the purpose.

Street. A type of entrance door that is installed at the entrance to a building and is designed for direct contact with the street. Such structures are subject to increased requirements in terms of protection from corrosion, and in heated rooms the thermal insulation properties of doors are also taken into account;

The solid dimensions of the metal entrance door with frame determine its heavy weight and increased requirements for the strength of the walls

Apartment. Since multi-storey buildings are built based on clear state standards, all apartments have standard sizes of metal entrance doors with a frame. In this niche, single-leaf doors predominate, although one-and-a-half-leaf designs are sometimes found in modern new buildings;

In apartment models, the size of the door with frame often corresponds to generally accepted standards

Office. Steel doors for an office are a rather vague concept, but most often this term refers to apartment models with increased burglary protection and enhanced sound insulation. Although when it comes to the street, corrosion resistance is added to the above-mentioned requirements;

In the office version, the size of a standard entrance door with a frame is something between apartment and street models

Tambour. One of the varieties of entrance doors designed to isolate a residential block of several apartments. As a rule, these structures do not have increased security against burglary and are rarely insulated;

Tambour models do not have a high level of burglary protection

Technical. The simplest and most affordable iron doors. Technical models are used as a temporary option in new buildings, and are also installed in utility rooms of offices in order to avoid claims from the fire inspector;

Technical doors are installed as a temporary option or installed on premises that do not need to protect material assets

Special. Traditionally, this includes all reinforced structures with increased security. There are more than a dozen options for such security, ranging from banal deadbolts to bulletproof doors with special protection from electromagnetic waves. Here, metal doors and frame sizes are selected individually, at the request of the customer.

Visually, the dimensions of a door with a frame with special characteristics can be similar to apartment models, the secret lies in reinforced locks and heavy-duty steel leaf.
Also, the dimensions of entrance doors with a frame strongly depend on the design features of the set, here we have 4 options:

Single leaf. Such models are installed everywhere, from technical rooms to safe rooms with enhanced protection. Non-standard doors are rare here, and according to the standard, the width of the doors ranges from 60 to 110 cm; it cannot be made wider, because the awnings will not support it;
One and a half. In such doors, a segment with a width of 20 to 60 cm is added to a full leaf with a width of 80 - 90 cm. The most popular standard size of an iron door with a frame is presented here in two models - 1280 mm (400 + 800 mm) and 1480 mm (600 + 800 mm) standard box thickness 40 mm (40+40=80 mm);
Bivalve. Here, 2 identical doors are enclosed in a single box. The size of the entrance door with a frame for double-leaf models ranges from 1280 mm to 1880 mm;

In both single-leaf and double-leaf models of metal doors, one of the two working leaves has the ability to be locked and swings open as needed, for example, to take out/bring in large furniture.

Doors with transom. A structure called a transom is a segment installed on top of the door block. Transoms are designed to compensate for openings that are too high. In this case, the transom can be installed on all of the above types of doors.

Design features directly affect the dimensions of steel doors with frames

Advantages of standard products

The real estate market is constantly evolving. Therefore, more and more apartment and house owners are focusing on individual doorways. At the same time, old unification solutions have a number of advantages.

Advantages of standard products:

In specialized stores and on the market there is a large selection of suitable ready-made models. Standard products are offered in a wide range of colors, with different decorative elements. It costs less than custom-made products. This makes it possible to save money and choose a suitable design.
Most apartments have a standard layout and identical openings. GOST characteristics ensure the most comfortable operation of the door block.
There is no need to change the dimensions of the opening to replace the old block with a new one.
If the blade is damaged, there is no need to replace the entire block. It is enough to purchase a standard canvas to match the existing design.
The production technology for standard products is fully established. This speeds up the manufacturing process and reduces the likelihood of defects.

What are the sizes of outdoor iron products?

Now the sizes of the entrance metal door with a frame are divided into standard and non-standard. The first direction includes products created on the basis of domestic standards, the second direction includes custom-made iron doors and models made according to foreign standards.

Standard

In domestic practice, standard sizes of doors with frames are regulated by several standards:

GOST 6629-88 is considered the most common; it regulates the dimensions of wooden doors, but since most of our houses were built during the Soviet period, when the doors were wooden, the size range of this GOST is also used for the manufacture of metal doors;
The main profile standard is GOST 31173–2003 (Steel door blocks). In terms of the use of dimensions, it is actually an analogue of the previous document;
Safe-type doors with increased security are produced in accordance with GOST R 51072–97;
But this list contains another very important document - SNiP 21-01-97, which specifies fire safety standards for the size and other characteristics of doors.

When classifying models, it is customary to start from the dimensions of the canvas, because these are the dimensions specified in fire safety standards. According to the above-mentioned documents, iron door leaves can have a width from 600 mm to 1100 mm, but there are nuances here.

Door entrance dimensions with and without frame (only door leaf dimensions)

So, according to fire safety standards for single-leaf structures, the standard dimensions of metal doors with a frame in apartments and private houses cannot be less than 800x1900 mm. In small offices, cafes, shops and other similar establishments, the minimum standard is 1000x2000 mm.

When it comes to street doors for multi-story buildings, the standard recommends the use of one-and-a-half and two-leaf structures. Installation of single-leaf iron doors with a leaf width of less than 800 mm is allowed only in utility rooms with a small square footage.

Non-standard

When arranging non-standard openings, you can order doors from a company or, as an option, weld them yourself. But ordering it will cost at least a third more than the production model, and not everyone can do it themselves.

But in addition to custom-made models, the required size of an entrance door with a frame can be found among imported doors. For example, the French and several other countries closely associated with France produce doors 10 mm smaller than our standards, and the British generally have their own measurement system, which is completely different from domestic requirements.

The size range of imported doors differs from domestic standards, and among these models you can find a door for a non-standard opening

If the doorway is high and the dimensions of standard doors with frames correspond to its width, then the gap at the top can be covered with a transom.

GOST for imported models

Often European models of metal doors attract buyers more with their design and lightness of construction. But the sizes comply with DIN requirements and are based on anthropometric data, for example, people in Finland are taller than in the south of the EU. Based on these parameters, standard door sizes may differ in height.

For example, if we compare French door options with Spanish ones, the difference in width is 90 mm. If in France the minimum width is 690 mm, then in Spain it is 600 mm, etc. In addition, the purchase of imported models will require some costs during installation if a reduction or increase in the doorway is required.

Metric and English door measurement systems

Since there are a large number of door designs from domestic and foreign companies on the market today, there are different computing systems in use. When choosing a door, consider the system offered by the manufacturer.

Metric

A simple metal door has the following parameters: height 2 m 4 cm, width – 82 cm 6 mm.
The reinforced metal door has the following dimensions: height - 2 m 5 cm, width - 86 cm.
Double doors, as a rule, have the following parameters: height - 2 m 41 cm 9 mm, width - 1 m 91 cm.

English

Many foreign manufacturers use the English measurement system when making doors. Standard doors have the following dimensions:

Height – 6 feet 8 inches.
Width – 2ft 9in.

If these indicators are converted to the metric system, they will correspond to: height - 2 m 32 mm, width - 84 cm.

It’s a shame, but today not everyone tries to adhere to standard parameters and standards. Consequently, people order custom door designs.

Advantages of standard sizes

When a home has a standard doorway, door installation is simplified. Here are some of the main reasons why it is preferable to install products of standard sizes:

There is a huge selection of doors. It will not be difficult to find a product of the desired color with a suitable degree of insulation, reinforcement, and cladding made of a beautiful and durable material;
the standard size makes it easier to install the front door. In addition, there is no need to wait for the design to be made to order. Installation time is reduced;
more favorable price, since identical products are produced in large quantities, no re-adjustment of equipment is required;
a standard door can be easily replaced with a new design.

Many consider the lack of individuality to be a disadvantage. But it is not so. Nobody forbids you to order an original standard size iron door that is not similar to others. It will still be cheaper than a canvas with individual sizes of the same performance class. Another thing is the original forms. Arched doors or products with other complex configurations are not included in standard products.

General information

So:

Most of the openings today in new buildings (P44 M, P44, P3 M) have dimensions in the range of 740–760 millimeters in width by 1,950–1,980 millimeters in height. Thickness varies.
In brick series houses they are usually in the range of 880–920 millimeters by 2,050–2,100 millimeters.
In old-type houses, for single-leaf doors, the dimensions of the openings can range from 830 to 960 millimeters in width and from 2,040 to 2,600 millimeters in height.
In nine-story houses of the seventies, it was quite common to have openings measuring 1,280 by 2,550 millimeters.

In general, the fact is that openings in houses from standard series have a greater variety of types (expandable, with no niches at the entrance, narrowing) and overall dimensions. Therefore, door dimensions can vary even within the riser or entrance of one house.

Standard sizes

According to clause 6.9. SNiP 210197 street entrance door - emergency exit. And in accordance with clause 6.16. The clear height of the emergency exit cannot be less than 1.9 meters, the width must be no less than:

than 1.2 meters - if we are talking about premises F.1.1. class, when the total number of people to be evacuated is more than fifteen people; if we are talking about premises and buildings of other functional fire hazard classes, with the exception of F.1.3. class, then the total number of people to be evacuated is more than sixty people.
than 0.8 meters in all other cases.

The dimensions of external products on staircases and doors to lobbies must have a width no less than the calculated width, or correspond to the flight of stairs, which is established in 6.29. In any situation, the width of the exit for evacuation must be of such a size that, taking into account the geometry of the path, it is possible to carry a stretcher with people on it through a door or opening without encountering obstacles.

In a broad sense, the dimensions of a metal door are determined by the relevant GOSTs, but their standards do not apply to doors for special purposes and products of unique objects. The required dimensions depend on the opening where they will be installed. Therefore, below are reference tables of typical dimensions of door openings.

GOST6629-88

"Internal doors for public and residential buildings"

Main dimensions:

Standard dimensions

Note: the numbers in parentheses are for door structures with swinging leaves.

Dimensions of openings in internal partitions and walls:

Dimensions of metal entrance doors according to GOST

The standard parameters of a metal door include dimensions of 203 cm in height in relation to 90 cm in width. When calculating the size of doorways, you should take into account the presence of framing around the perimeter of the entrance. In old buildings it is made of wood and must be removed when replacing the structure. In new houses, in most cases, such edging is made of metal and its removal is extremely difficult. Therefore, most often the width of such a passage is calculated taking into account this element.

In addition, quite often, to expand functionality, the width of the door passage can be significantly increased. Door structures with two leaves are installed in the enlarged opening.

Single-leaf and double-leaf models

The height of structures can vary from 2 meters to 2.3 m. In some cases, transoms are installed at the top of the opening. This is typical for a private house, where the opening size for the entrance iron doors is too large. They don't have to be rectangular. The arched shape with stained glass glazing looks beautiful in a country house.

As for the width, it differs for different types:

Single-leaf structures are equipped with one leaf. It can be narrow at 600 mm or 650 mm wide. Such models are installed in typical premises, technical, warehouse. Standard canvases are more common.
Bivalve valves can have both working parts or only one; they are also called one-and-a-half. They have one part, narrower, that closes tightly and opens only when necessary. The width of one-and-a-half doors can be 1200 mm with a working part of 800 mm, as well as 1400 mm with working dimensions of 800 mm or 900 mm.
Double doors have both leaves of the same size and are equally functional. Each sash will be 600, 800 or 900 mm wide.

Parameters for non-standard openings

The dimensions of metal entrance doors with frames can be non-standard. Such products are found in houses with large openings and non-standard design. The design regulated by GOST will not be suitable in this case, so the dimensions of the entrance doors with a frame can be as follows:

Width – more than 200 cm;
Height – 250 cm.

Such designs are made according to individual customer measurements. But before installing such large doors, it is worth knowing that this can affect the strength of the walls themselves.

How to find out the size

Ideally, in order to correctly calculate the optimal dimensions of doors with frames, it is better to take dimensions from a clean doorway (without old doors and plaster). But if this is not possible, then it is necessary to dismantle the platbands and slopes, and then take measurements based on the actual dimensions of the opening.

The dimensions of the opening are taken in 4 stages:

Measure the bottom, center and top of the opening horizontally;
Measure vertically on the right, left and center;
Measure the diagonals;
If the sizes of the diagonals do not coincide, which happens quite often, you need to take a plumb line and find out in which direction and how much the deviation goes. In this case, the actual dimensions of the box are calculated only horizontally and vertically; deviations are not taken into account.

According to the rules, the gap between the frame and the doorway should be within 10 - 20 mm. The box cannot be placed close to the walls, otherwise the doors will jam at the slightest shrinkage of the building.

Direct contact with the base is allowed only on the floor and at the skewing points of the opening, if any. If the gaps are larger than 30 mm, then the opening is leveled with cement-sand mortar. Allowable gaps of 10 - 20 mm are filled with polyurethane foam

When installing a door with a frame, the opening dimensions should be 10 - 20 mm larger than the structure

Chinese door sizes

This type of door is very popular today and some companies can resell them under the guise of their own. As for technical characteristics, such models are manufactured according to international standards. Therefore, the dimensions of Chinese entrance metal doors with frames are close to our GOST standards. The width of the single-leaf structure is 86-96 cm, and the height is 205 cm. Single-leaf products have a width of 120 cm.

These characteristics may differ slightly from those declared by the manufacturer, so before purchasing a particular product you should double-check everything using a tape measure.

How to expand a metal door frame without removing it

The expansion of the door frame has to be done when the thickness of the wall is greater than the size of the frame. To do this, use additional strips matched to match the door trim, plasterboard sheets, solid wood slabs, MDF panels or laminate. The finish is quickly installed, masks installation defects and gives the entrance area an aesthetic appearance. The width of the slats is 70–400 mm. The thickness of the skin should be 15–25 mm to withstand the loads during operation. For fastening, liquid nails, polyurethane foam, building mixtures or lath lathing are used.

Selection of entrance iron structure

A very important task, because a lot depends on the correct choice of design and therefore the following characteristics are taken into account:

Correspondence between the size of the door leaf and the dimensions of the leaf. You should definitely pay attention that the dimensions of entrance metal doors with a frame in height and width should be 5-7 cm less than the same parameters of the doorway. If the opening is of a non-standard size, then it can be narrowed or expanded to fit the required door parameter;
If you plan to install a door with a non-standard design, then it is worth analyzing all the pros and cons, because mounting such a product, for example, in a load-bearing wall will lead to a violation of the geometry and further negative consequences;
Heat and sound insulation. The correct choice of this parameter will allow you to create comfortable living conditions in the room. Since the metal structure allows cold to pass through, installing it outdoors can lead to the formation of condensation and ice on the canvas. To avoid this, it is recommended to buy a door with a thermal break;
If the door is installed in an apartment, then you can purchase an iron structure with conventional insulation;
Specifications. Here it is necessary to take into account all the parameters, from thickness to fittings. The second is given special attention, because the protection of the house against burglary will depend on the quality;
Good metal door structures are made of steel with a thickness of at least 2 mm. In order to make it more difficult to break into the structure, it is recommended to use hidden hinges.

So, the main task when choosing an entrance door is to choose the right product according to the height of the opening and its width, but the thickness can always be adjusted using an additional strip.

Dimensions of door blocks in different rooms

Apartment door sizes

Accepted standards for the size of entrance doors to apartments differ according to house-building series. In general terms, the width of the opening in a panel house can vary from 740 to 960 mm, and the height - from 1950 to 2600 mm. Accordingly, the minimum size of the entrance door is 700x1900 mm, and the average size is 800x2000 mm.

Dimensions of doors to a private house

In this case, it is more difficult to determine what dimensions of a metal door will be suitable. Such dwellings are built for reasons of personal comfort, so it is advisable to measure the size of the entrance street door of a country house on site. In our practice, the most common openings for door blocks are 900x2100 mm.

Measuring rules

The exact size of the doorway is determined by measuring. In this case, you should adhere to the following rules and recommendations:

Measure the width and height in the presence of good lighting, in the direction from the left slope to the right, from the upper slope to the bottom of the wall opening.
Take measurements using a tape measure.
If an entrance door is installed, it must be dismantled before determining the characteristics of the opening.
If the slopes have crumbled or crumbled, you need to contact a specialist. The doorway should be measured after they have been restored.

Following these rules will help you avoid mistakes. Having received accurate measurements, we move on to determining the parameters of the door block and choosing a model. The dimensions of the structure should be reduced by the amount of the installation gap between the frame and the wall. Set the distance between adjacent surfaces as follows:

along the length of the opening - 1-5 cm between the upper slope and the crossbar of the door block (leave a distance from the side of the threshold);
the width of the opening is 1-5 cm on each side of the vertical slopes.

It is recommended to determine the parameters of the doorway for installing metal or wooden panels together with a partner. This will be more convenient and faster.

Dimensions of the entrance metal door

The door at the entrance to a house or apartment is always larger than the door that separates the corridor and the kitchen or other rooms. This is done for a reason: through small doors it will not be possible to carry a large item, for example, a sofa.

For an exterior metal door on a stairwell, tightness is a taboo. The narrow passage will become a serious obstacle when evacuating people.

According to SNiP, the standard height for metal entrance doors is 2100 mm. And the width can be selected from the following size range: 600 mm, 700 mm, 800 mm and 900 mm.

According to standards, the width of a metal door can be 600, 700, 800 and 900 mm

A metal sheet with greater parameters is intended exclusively for emergency exits, which are organized at special-purpose facilities. In other words, widths from 900 to 1200 mm are a feature of fireproof, armored and soundproof doors.

Dimensions of frame and door opening

Taking into account the frame, the size of the entrance metal door increases by 60–70 mm, since 30–35 mm are added to the door leaf on each side. It turns out that the previously indicated widths change to 660–670 mm, 760–770 mm, 860–870 mm and 960–970 mm.

The frame accounts for 60 mm of the width of the doorway, the rest of the space is occupied by the metal sheet and technical gaps

The dimensions of the door reflect SNiP, which contains requirements regarding the optimal width of the opening and threshold. The area of passage into an entrance or apartment cannot be narrower than 1010 mm.

The standard opening width for a single-leaf door is 1010 mm

Depending on the type of residential building, there are several options for the width of the doorway:

101 cm - for installing a single-leaf door at the entrance to a private house;
131, 151 and 155 cm - for arranging a one-and-a-half door structure;
191 or 195 cm - for an entrance group of two doors.

It is very strange, but an opening made in a living room does not always fit a standard size door. For example, in my apartment, located in a new multi-story building, the width of the doorway area is 76 cm and the height is 200 cm. My relatives, the owners of an apartment in a nine-story building built in the 70s of the last century, have the same absurd situation. True, they do not complain, because the opening leading to their home is very spacious - 128x255 cm. This is often found in small brick houses.

The doorway may be wider or narrower than needed if standard door sizes were not taken into account during construction

The threshold - a natural addition to the door of a private house - is required to be made in such a way that it does not let heat out of the room and blocks access to noise from the outside. Only a height of 2.5 to 4.5 cm can make a threshold function under serious conditions.

The optimal threshold height is 4.5 cm

When understanding the appropriate dimensions of the metal sheet, you should take into account the technical gap, without which it is impossible to install the product. Be sure to leave 1 or 2 cm of clearance between the front door and the wall on all sides.

The dimensions of the threshold must be taken into account when choosing the height of the door frame.

The width of the doorway must be such that when installing the door there remains a technical gap of 1 cm

Main characteristics of doors

The product has several parameters that should be taken into account when purchasing and installing. These include the geometric dimensions and weight of the canvas. The weight of the sash, in turn, depends on the width and height, as well as the thickness of the metal sheets.

Typically, the weight of standard size metal entrance doors is 70-80 kg. If the product is too light, weighs 50 kg or less, then it is not worth buying. This fabric is not durable and can be easily opened.

There are two types of metals used to make doors: aluminum or steel. The first is lighter, and the second is stronger. Also, when choosing products, you should take into account the purpose of the entrance system, its type, and design features.

The door kit includes:

Box It is made in the form of the letter P, supplemented with a threshold if necessary. Made from metal corner. The thickness of a metal door frame is usually 80-90 mm.
Sash. It is made in the form of a canvas, consisting of sheets of metal welded together.
Stiffening rib. They protect the structure from warping, twisting and other deformation. They can be transverse or longitudinal, often both types are combined.
Interior and exterior finishing (wood boards, MDF or plastic panels, paint, artificial leather).
Insulation. It can be located inside the canvas or outside under the finishing material, for example, leatherette.

In addition, all accessories are included in the kit. This includes hinges, locks and other locking mechanisms (latches), eyes, closers, handles, rubber seals.

If you need to install a door in a country house, before purchasing it you should think about installing a canopy. It's better to order it right away. This simple device will protect the canvas from precipitation and direct sunlight, thereby reducing fading.

Correct measurement of the opening for a metal entrance door

To accurately determine the size of the opening, and therefore easily select a suitable metal door, perform the following tasks:

Find a convenient measuring tool - a construction tape. It is not prohibited to take measurements with a regular ruler, but it is unlikely to give accurate data on the height and width of the doorway.

When measuring the opening, determine the width and height

Measure the gap between the vertical areas of the opening. Millimeters are always taken as a unit of measurement, since it is in them that door manufacturers are accustomed to specifying dimensions. The first measurement is taken at the top, the second at the bottom. If they find that the obtained values differ from each other, then another zone is measured with a tape measure - the distance between the middles of the vertical parts of the opening. Each number is written down in a notepad.

The width of the opening is not equal to the width of the door leaf, because, in addition to it, a frame is installed in the opening

The resulting values are compared to select the smallest one. This is what the salesperson at the door store will need to voice.
In three approaches, measure the gap from the top to the bottom border of the doorway. Measuring the distance between the middles of the passage is done just in case. The resulting figures are stored on paper. The minimum value of the door height, as well as the width, is reported to the salesperson in the door store.

It is recommended to measure the width and height of the opening at different points

When searching for a metal door intended for installation at the entrance to a house, be sure to take into account the dimensions of the opening, door frame, threshold and gap, which simplifies installation work. Only an integrated approach will help you become the owner of a reliable product.

How to dismantle a metal door frame

Installation of a new door begins with dismantling work. The canvas must be removed from the canopies, the trim and trim on the slopes must be removed using a hammer drill. Then you need to remove the threshold to make it easier to work with the sidewalls.

Unscrew the fasteners holding the box in the opening. If they do not give in or steel pins were used for fixation, then they are cut off with a grinder with a cutting wheel. The gap between the wall and the frame should provide access to the fasteners. Otherwise, it will have to be expanded by installing a lance in the hammer drill chuck. Using a tool, the plaster is carefully removed at the attachment points, and the polyurethane foam is cut out with a knife.

Trimming should begin from the bottom and gradually move upward to avoid the beam spontaneously falling out and causing injury. First you need to dismantle the side posts, and remove the horizontal part last. The beams may have to be cut in several places and pryed up with a crowbar or scarpel. The cuts must not pass through the lock mate.

What are the standard and minimum sizes of entrance doors in apartment buildings?

Thanks to standard doors, companies have the opportunity to use special equipment that does not require additional reconfiguration to fit the minimum dimensions.

Standard door leaves have the following advantages:

You can always find a large assortment of doors on the market, which makes it possible to choose the most ideal model, taking into account your wishes and preferences. Companies produce classic models from metal, insulated versions that are not afraid of temperature changes.
Easy installation. The doors almost match the size of the openings. They are attached simply: the door is fixed using anchors. Non-standard elements are more difficult to install. Here it is necessary to further expand the doorway.
Price. Standard doors significantly reduce costs. And all because production algorithms are used that can be automated without problems. Many modifications are made from inexpensive materials. This also affects the cost of the product.
Versatility. After installation, doors can be replaced without any problems: the old leaf is dismantled and a new one of standard size is inserted.

There are minimum and maximum parameters. To choose the right door for a new apartment, consider the following standards:

If you purchased an apartment in a new building, then you will have to buy a door: height 1 m 95 cm - 1 m 98 cm, width 74 cm - 76 cm.
If your future apartment is located in a brick apartment building, then a door will suit you: width from 88 cm to 92 cm, height from 2 m 5 cm to 2 m 10 cm.
In old apartments, the following designs are suitable: from 83 cm to 96 cm (width), from 2 m 4 cm to 2 m 60 cm (height).

Degree of protection

The specific purpose of the entrance group is also a determining factor when choosing the size or design of the opening. This is how standard and technical doors differ: fireproof, armored, sound or moisture insulating. The characteristics of special structures significantly increase the degree of protection of housing.

For example, the thickness of a fire door is 7 cm, and an armored one reaches 10-12 cm. The dimensions of fire-resistant structures are more impressive and can reach about 2500x2500 mm, which is due to the requirements for their passability during evacuation. Armored ones can also have non-standard dimensions (1200x1900 mm), but are more often produced with dimensions of 1200x2050 mm.

When choosing the optimal entrance structure, it is very important to consider how much the metal door weighs, its thickness and other dimensional characteristics. It depends on this whether it will fit the opening and whether it will be able to protect the house from break-ins, cold and drafts.

Choice of box and canvas

The first condition for choosing the size of the box is that it must fit into the opening. When choosing a door for known opening dimensions, experts recommend relying on a simple technique. The width of the canvas plus 7 cm should be a value close to, but not exceeding, the width of the opening.

In the video you can familiarize yourself with the rules for measuring the front door:

The width of the canvas of domestic products starts from 60 cm, increasing in increments of 10 cm to a value of 90 cm. The width of the most popular product is 80 cm, and the height is 2.1 m.

European and Chinese doors are made according to different patterns. This should be taken into account when choosing. In cases where it is impossible to select a product to fit the opening, the design is made to order.

The gaps between the opening and the frame must be sufficient to adjust the position of the latter in all planes. It is better to purchase an assembled structure - you will not have to worry about choosing dimensions and displaying the canvas.

Armed with such recommendations, you can begin to select, purchase and install the structure. It will comply as much as possible with the norms and requirements of regulatory documents. And, besides, it will last for many years.

Variety of interior doors

Basically, all interior doors are divided into three categories, which are based on purely constructive solutions.

Swinging, when the canvas opens by twisting around hinges.
Sliding, when the canvas moves along the wall along guides.
Folding, when the structure folds like a book, opening a passage.

Swing

The most commonly used type. People’s conservatism sometimes reaches the point where swing models are installed even where they don’t belong.

pros	Minuses
Simplicity of design	Opening requires a certain amount of space. In narrow spaces this can cause some inconvenience.
Easy to install
A good degree of sealing of the gaps between the frame and the canvas, which ensures noise and heat insulation of the room

Sliding

These models are often called sliding doors. There are two varieties here, which differ from each other in the openness of the canvas when opened. That is, it simply moves along guides along the wall or is recessed into the wall itself. The second option is preferable, but it is difficult to install.

The disadvantages include the fact that special fittings are required for installation. And the installation process itself is not easy. Like swing doors, they can be single- or double-field. In the second case, the doors simply move apart in different directions when they need to be opened.

Folding

By the way, the first two options can be designated as the standard size of interior doors with a frame. What can not be said about the folding design. This is the most convenient way to cover non-standard openings. The canvases in them are fastened together with hinges, and movement is carried out on rollers. In this case, the number of sashes can be unlimited. Everything again will depend on the width of the opening.

It should be noted that the minimum width of one leaf is 10 cm. That is, the smaller this indicator, the more sashes will have to be made for the structure. Although such models look very original.

The advantages include the ability to close curved openings. But there is one single drawback that is quite serious. This is a loose connection of the canvases both with each other and with the box. So no tightness.
