Entrance door sizes: standards and guidelines
Door leaves are used in any room where you need to restrict access to it. One of the most popular components are entrance rails, for which special requirements are provided. An important characteristic of such a structure is its dimensions, which must correspond to the technical parameters of the opening. The dimensions of the entrance doors, standards and advice will allow you to choose the optimal system.
Doorway Standards
Installing a door leaf is a relatively simple operation, which primarily requires high-quality measurements of all dimensions.
The main factor here is the size of the doorway where the street structure will be installed. This value, according to the standards, must correspond to the dimensions of the entrance doors with a frame.
Doorways come in several standard sizes, which have a dependence of width on height.
The openings that are suitable for single-leaf entrance doors have the following dimensions:
- 630-650 * 1940-2030 mm (range of width and height, respectively);
- 660-760 * 1940 * 2030 mm. The door groups considered are the smallest and are relatively rarely installed today;
- 660-760 * 2040-2100 mm;
- 770-870 * 2040-2100 mm;
- 880-970 * 2040-2100 mm.
The openings where you can install one-and-a-half or two-leaf door systems are distinguished by already increased width and height values.
- 980-1100 * 2040-2100 (ranges of width and height, respectively).
- 1280-1300 * 2040-2100 mm.
- 1480-1500 * 2040-2100 mm.
- 1580-1600 * 2040-2100 mm.
It should be noted that these dimensions are slightly larger than the dimensions of the doors themselves together with the frame. This allows you to quickly install the system and, if necessary, adjust the position of the door leaf in the wall opening.
There are also openings that allow you to mount doors with a width of up to 1800 mm, but these dimensions are not standard and are found only in private houses, although many manufacturers today produce their products for such openings.
What are the designs of canvases
Doors are not always manufactured according to regulations and standards. This is due to the fact that many owners of private houses equip different types of doorways, so the market for entrance structures is saturated with many varieties, which can be divided into several types.
- Doors with transom. A feature of this design is an additional insert above the door leaf. It is designed to close the opening with a non-standard doorway height;
- Single leaf. These are standard types of entrance doors that consist of one leaf. Their width can vary from 60 to 90 cm, depending on the manufacturer. This type is the most common and is installed both in residential apartments and in industrial facilities.
- One and a half. The leaf of such a door consists of two moving leaves, which are fixed in the frame, but one of them is much smaller than the other. Often, the width of the small side can vary in the range of 40-60 cm, depending on the dimensions of the second sheet. Such double doors are used only for the purpose of expanding the opening for convenient use or when it has non-standard dimensions.At the same time, the small sash almost always remains motionless and opens very rarely.
- Double doors. These systems consist of two full-size leaves that correspond to the standard sizes of single-leaf counterparts. The width of both parts is equal and can be 60, 80 or 90 cm, depending on the type of construction. Double-leaf canvases are perfect for country houses, where the wall opening is much easier to adjust to their size, while one leaf can be fixed in the box, and the other can be used as the main one.
In some cases, both canvases move, but this is extremely rare in typical entrance doors.
Installation guidelines
Entrance doors are not only an object for protecting a home, but also a kind of barrier when leaving. According to modern GOSTs, these structures also represent service exits for operation in emergency situations, therefore, all the characteristics of doorways (both for a country house and an apartment) must comply with these requirements (SNiP 210197). It is important here that the exit allows you to evacuate quickly and efficiently.
Therefore, it must have the following parameters.
- The minimum height must be 1900 mm;
- The free space of the open door must exceed 800 mm.
If the doors are installed in public places (cafes, offices, etc.), then they must be equipped with a structure with a width of at least 1.2 m. In turn, the minimum height remains the same as for cottages and other types of private houses.
As for the outer doors (front doors) of multi-storey residential buildings, the width of the opening should not be less than the flight of stairs. This is necessary to ensure the evacuation of people in case of fire and the like. Almost all manufacturers are guided by these recommendations and produce canvases that meet these requirements.
Today there are several brands of standard entrance metal doors, which differ in their dimensions:
- 21-9. This design is equipped with a box measuring 2071 * 870 mm, and the canvas itself is 2000 * 800 mm;
- 21-13. Doors of this brand are complemented by a box 2071 mm high and 1272 mm wide, into which a product with dimensions 2000 * 1202 mm is placed. Often such characteristics have one-and-a-half models, which are complemented by two sashes of 800 mm and 400 mm in size;
- 21-15. Optimal door leaf sizes for double-leaf modifications. The system is complemented by a box with dimensions of 2371 * 1472 mm, and the canvas itself has dimensions of 2300 * 1402 mm;
- 21-19. This type of design is the largest. Box dimensions reach 2371 * 1872 mm. Inside this frame, you can install a canvas with a height of 2300 mm and a width of 1802 mm. They also use two sashes, which have a width of 900 mm.
Please note that this list is not complete and is supplemented by several more modifications with distinctive parameters. According to the standard, there are several more modifications of such structures. This document describes not only the dimensions of the products, but also the characteristics of the sections of each of their types.
It is only necessary to carry out all calculations when choosing doors according to the outer dimensions of the box.
If you take into account only the canvas, then the opening may be simply small for this system, and in the future you will have to expand it or buy a new door structure.
Advantages of standard sizes
Standardizing door leaf sizes is one way to optimize the production of these products. This allows companies to use custom equipment that does not need to be reconfigured for minimal dimensional changes.
Standard sizes have several advantages:
- Presented on the market many modifications of door leaves... This allows you to choose the optimal model for every taste or style of the room.Manufacturers produce not only classic metal models, but insulated options that are not afraid of temperature changes;
- Easy to install. This is due to the fact that the door leaf practically coincides with the dimensions of the opening. To fasten the structure, you just need to fix it with special anchors or other mounting systems; to install non-standard one-and-a-half modifications in the opening for single-leaf models, you need to expand the opening. Please note that this will lead to time and money costs (use of auxiliary tools, purchase of additional finishing materials, etc.);
- Price. Standard door sizes can significantly reduce their price. This is achieved by using the same production algorithms that can be easily automated. Some modifications are made using cheap materials, which also affects the price;
- Versatility. Installed doors in such an opening are very easy to replace with new ones; for this you just need to dismantle the structure and insert a standard product instead of the old one. All this will require a minimum level of preparation of the opening.
Features of measurement systems
Door leaf manufacturers have to focus on a variety of characteristics. One of these parameters is the measurement system. The English type is considered classic, which involves the calculation of all dimensions in feet.
According to this system, standard doors have the following dimensions with conversion to the metric system:
- Height 6'8 ''. In the metric system, this value is 203.2 cm;
- Width 2'9 '' (84cm).
In our country today, a metric system for measuring door leaves is adopted.
The standard sizes of these products are slightly different from the English ones:
- Width can vary from 60 to 160 cm.;
- The height, in turn, should be no more than 205 cm.
It should be understood that there is still a slight correspondence between these systems, and this allows in some cases to replace doors of one type with another. It is also important to take into account not only the dimensions of the canvas, but also the dimensions of the opening itself. When buying, be sure to clarify on the basis of which system the products were manufactured, this will eliminate unforeseen problems, such as the discrepancy between the elements of the installation system and the existing opening.
How to measure the parameters correctly
Entrance doors are installed in order to protect the house from burglary, so it is so important to choose the optimal designs that fit into the doorway and securely fix in it. The algorithm for measuring the parameters of the opening can be divided into several sequential steps:
- Before determining the dimensions, you need to get access to the end of the wall to which the door frame is attached. If you have an old structure installed, then you need to dismantle the platbands that cover the wall;
- Then you can start measuring. All characteristics of the opening are measured in several places. This is necessary in order to obtain optimal results. Sometimes the opening can be skewed, then, having taken a measurement at a random point, you can choose the wrong product. Only the minimum values need to be taken into account;
- If the door leaf is dismantled, then before measuring, it is imperative to check the quality of the finish of the ends. If there is plaster on the surface of the wall that will crumble, it is better to remove it before measuring. If necessary, you can also align the contours of the hole to give it the most correct shape.
After taking all measurements from the opening, the obtained values should be compared with the standard ones. Often, many doors correspond to similar parameters, since they a priori should have classic dimensions.
Each opening has a certain correspondence with the door leaves.
- A hole with dimensions of 208 * 88 cm is intended for installation of a structure in which these values do not exceed 205 * 85 cm;
- The entrance passage with dimensions of 210 * 100 cm will accommodate a door with dimensions of 207 * 97 cm;
- If it is planned to install reinforced door structures, then the size of the opening should be only 1-3 cm larger than the box.For example, products with dimensions of 205 * 86.5 cm will fit an opening 89 cm wide and no more than 208 cm high.
Please note that almost all door structures for each of the criteria (height and width) are about 3-4 cm smaller than the hole where they are installed, therefore, having measured the dimensions of the doorway, it will not be difficult to find out the technical characteristics of the modification. After that, you just need to compare the obtained values with the standard dimensions of factory products and choose the right model.
When calculating the dimensions, one should take into account not only the parameters of the canvas, but also the thickness of the door frame.
As for the thickness of doors and frames, these characteristics are often not important. This is due to the fact that the width of the end of the wall in most cases is much larger than the thickness of the canvas, but this factor is especially important if the door is bought in order to protect it from burglary or to warm the room. The simplest metal and wooden structures are about 5-6 cm thick. They are equipped with a classic set of functions and cannot always provide high-quality thermal insulation.
There are special armored doors on the market that not only protect the house, but also keep the heat inside. Such products are already equipped with internal insulation and thicker steel sheets. Due to this, the thickness of the web increases.
A simple algorithm for calculating the dimensions of a door structure involves the summation of several characteristics:
- Width or height of the canvas;
- Door frame thickness;
- The width of the mounting gaps between the box and the wall.
In this case, the width of the gaps and the thickness of the box must be taken into account twice. When calculating the height, you must also add the threshold parameters, if it is present. If you are not sure that you can get all the necessary characteristics correctly, it is better to entrust the measurements to the installer. Often, this role is played by the store where the doors are purchased, and its specialists deliver and install them.
How to choose by type of house
Door leaves were constantly improved, which led to periodic changes in their technical characteristics. Today, many old panel houses are equipped with structures that do not correspond in size to modern trends. This not only complicates the manufacture of products, but also complicates the process of installing new systems.
Each type of house has used a certain type of door leaf before:
- Brick five-storey premises. In such structures, doors with dimensions of 860 * 2050 mm were often installed, but some unscrupulous developers deliberately narrowed these holes, which now does not allow installing a standard modification of the door leaf here. Therefore, before replacing such a device in a five-story building, it is imperative to measure all parameters;
- The so-called "stalinka". A feature of such buildings is that the doorways here have an increased height, which today does not fit almost any modern standard. In some cases, this size can reach a value of 2300-2400 mm;
- Panel houses. The dimensions of the doors in these buildings often correspond to modern requirements. There are openings with dimensions 860 * 2050 mm and 960 * 2050 mm. Under these values, today you can choose doors that are produced by manufacturers, therefore installation in such buildings is often not difficult and requires only compliance with technology.
Choosing doors for "Khrushchev", it is advisable to be guided by a few simple rules.
- Be sure to take measurements of the opening before buying a door. This is necessary, since many holes do not have standard dimensions, and they are also skewed. All these factors can affect the design features of the frame and the door leaf itself;
- The door should open in such a way as not to interfere with neighbors. This is important if the building has a block system and several apartments are located on one section. It is better for the canvas to move inward, but it all depends only on the specific features of the location of the room;
- Pay attention to the technical features of the products. The canvas must be strong and durable. Do not buy products that are made of steel sheet less than 1.5-2 mm. Also evaluate the method of fastening the structure to the wall, the type of hinges (internal ones are better than external ones), the quality of the fittings. Particular attention should be paid to locks, since the burglary resistance of the canvas depends on this. The best option would be a system with two or three locking mechanisms;
- Design. This feature is selected only according to personal preference. Experts recommend buying canvases that are combined with the main style of the room and the outdoor unit;
- Insulation quality. This characteristic determines how well the canvas will retain heat inside the room. Quality doors are made using several thermal insulation materials. If the canvas goes directly to the street, then a door with a thermal break would be the best option. It will provide heat retention and prevent condensation from forming on the metal surface;
- Material. In the role of entrance doors to both the house and the apartment, they mainly use metal structures, since they are durable and reliable. Wood products also do a good job with these tasks, but in order for them to function for a long time, you need to constantly take care of them.
The sizes of door leaves and openings can be different, which allows you to create high-quality, beautiful, well-insulated, soundproof and durable entrance groups. Please note that expanding the opening is not always the best solution for installing a door.
It is best for such a hole to immediately correspond to the parameters of the purchased door leaf, since this will allow you to get a strong and reliable structure with minimal financial and labor costs.
