In order for the installation of a new door to go quickly, and the installation gap with slopes to be beautifully sealed, it is important to choose the right size of the entrance metal doors to the apartment. Since building codes have varied from time to time, openings in high-rise buildings can have different heights and widths, so there are several common design standards that fit most apartments, where the gap between the frame and the wall can be closed with casing on the outside and foam on the inside. For greater accuracy in determining whether a given opening is standard, it is better to resort to free measurement services.
Recommended sizes of entrance doors for various opening sizes
The dimensions of entrance doors in a private house and city apartment are regulated at the legislative level. The main document is GOST. But the data given in it is approximate. After all, houses are built according to different designs. Accordingly, the dimensions of passages in Khrushchev and frame houses differ. It is important that the door block matches the passage. Otherwise there will be problems with its installation. You will have to expand or narrow the opening. If the canvas with the box does not fit the passage, then its installation will not proceed correctly and functionality will be impaired. Therefore, it is better to know the parameters of entrance doors for different openings and take them into account when selecting and installing a door structure.
Table of correspondence between parameters of doors and openings
It is recommended to make passages of certain dimensions for doors of specific sizes. Below is a correspondence table. It shows the height and width of the opening and door structure in mm.
| Door frame dimensions | Door leaf dimensions | Recommended opening height and width |
| 615x1923 | 550x1880 | 635x1935 |
| 665x2043 | 600x2000 | 685x2025 |
| 765x2043 | 700x2000 | 785x2025 |
| 865x2043 | 800x2000 | 885x2025 |
| 965x2043 | 900x2000 | 985x2025 |
| 665x2143 | 600x2100 | 685x2155 |
| 865x2143 | 800x2100 | 885x2125 |
| 965x2143 | 900x2100 | 985x2155 |
These standard sizes (width and height) of openings and entrance doors in an apartment or in a private house should be followed. But they are not strict. More stringent data regulates the standards. The thickness of the box is selected to match the depth of the wall.
Dimensions of entrance doors according to GOST
Door leaves can be made of wood, metal, plastic, MDF. The first two options are more often used for installation at the entrance to the room. Blocks made of different materials have their own dimensions according to GOST.
For entrance metal doors
The dimensions of metal entrance doors in an apartment are determined by GOST. They depend on the design features of the product. Iron entrance doors are standard and reinforced. In simple designs, the width of the metal door leaf is 0.826 meters and the height is 2.04 meters. Reinforced models are larger in size. Their width is 0.86 meters and height is 2.05 meters. These values apply to single-leaf products. Double-leaf varieties of metal entrance doors have a width of 1,910 meters and a height of 2,419 meters.
Wooden
On average, wooden doors are made 2.10 meters high and 0.9 m wide. This applies to left- and right-sided models with cladding. The dimensions of entrance doors made of natural wood are determined by the influence of various factors. Among them, it is worth highlighting the number of sashes, the size of the threshold strip, etc. Protective strips are always installed. Their parameters depend on the material. Wooden products are produced with a thickness of 1.6-1.9 cm, plastic - 0.2 cm, and chipboard - 0.3 cm.
Expert tips and advice
Boxes are made of wood, fiberboard or MDF. Each material has pros and cons. When installing fiberboard boxes, the structure will bend from the weight of the panels, so it is not recommended to install such boxes. It is better to take wood or MDF.
The tree lasts a long time and looks beautiful. Any rocks are suitable for slopes. But more often they install MDF with PVC film. Designs with laminated film are not expensive, but require careful handling with sharp objects. If the film is scratched, it cannot be restored. Some people remove the protective film after installing the panels in the opening to minimize damage.

Not really
During major renovations, openings must be measured after finishing the walls and laying the flooring. During the process, the floor level and the width of the walls may change, which will lead to a large change in size. If there are wires in the trim, then calculate the optimal removal so that they spoil the appearance.
It is important to take into account the opening side of the doors, because the frame can be ordered with holes made for the hinges. And if the side is left instead of right, you will have to buy new elements. To determine the side of the door, look at which hand the leaf is on when opening. If the handle is on the left, and the door opens completely to the right, then the door is right-handed; and if it’s the other way around, it’s left. You can also identify it by the hinges, the left hinges are on the left door; and the right hinges are on the right door. For European doors, the concept of left and right is exactly the opposite. What is left for a European is right for us.
How to correctly take measurements of the opening under a metal entrance door
The dimensions (width and height) of the door leaf and frame are selected to fit the opening for the front door or interior door. Therefore, it is useful to know how to measure a passage. A metal door block is often installed at the entrance. Therefore, it is worth understanding the determination of the size of the doorway for a structure made of such material.
Opening width
To understand how wide the door block is required, you need to measure the width of the doorway. To do this you need a tape measure or a centimeter. The dimensions of the opening are measured from below, above and in the middle. The lowest result is selected and recorded. Measurements are taken from both sides of the apartment or house. You need to measure a clean opening. Cashing and plaster should not be present.
Doorway height
To choose the right metal door for the size of the opening, you need to know the height of the opening. To do this, measurements are taken. It is more convenient to do it using a tape measure. Measure the entrance door opening in three places, starting from the top edge of the opening to the finished floor, finished with tiles, laminate, parquet, etc. You need to measure in three places: on the right, left and in the middle. Measurements are taken from the entrance and apartment. Record the lowest value.
Opening depth
When determining the dimensions of a doorway, an important indicator is depth. Use a tape measure to measure the distance from edge to edge of the wall. Do this on the right and left sides. The entire value is recorded. You need to choose the minimum. This will be considered the depth of the passage.
Current standards
Currently, each of the entrance doorways, according to paragraph 6.9 of the regulatory document SNiP 210197, is an object related to emergency exits. Therefore, one of the main requirements is to ensure free and rapid movement in the event of an emergency evacuation. For these purposes, the door structure located as an entrance must comply with the minimum permissible dimensions.
Thus, it is regulated that the minimum height must exceed 1900 mm. And the width of the doorway for residential premises cannot be less than 800 mm. At the same time, the dimensions of doors for office and other public premises have a minimum of 1900 * 1200 mm.
The front metal structures of apartments in multi-storey buildings must match or exceed the width of the flight of stairs in their dimensions. These requirements are contained in the SNiP document under clause 6.29. Such design solutions, based on calculations, make it possible to ensure safety and evacuation measures for all residents of an apartment building.
In addition, compliance with standards will allow the smooth delivery of large pieces of furniture and large household appliances.
How to measure your front door correctly
When choosing an entrance door, you need to decide on its size. They usually depend on the dimensions of the passage. But they may differ from it. After all, the opening can be changed if desired: made higher or lower, wider or narrower. You need to know what sizes the door frame and leaf are required.
The door should be approximately 10-15 mm smaller than the passage under it. The clearance is required for proper installation and adjustment of the door structure. A large gap is undesirable. This will negatively affect the thermal insulation and sound insulation qualities, as well as the strength of the door. Therefore the maximum value is 15 mm. Therefore, having decided on the parameters of the opening, you need to subtract 10-15 mm from below, above, and also on the sides. It turns out that the door block should be 20-30 mm narrower and lower than the passage.
Standard opening dimensions for apartment buildings
There are standard sizes of a doorway in a house. The standard also approves the dimensions of the door leaf for different passages in apartments.
GOST sets the height from 2100 to 2400 mm. The width can be 910, 810, 1010, 1210 and 710 mm. A door leaf 800x2000 with a frame should have a size of 870x2071 mm. This design requires a doorway with dimensions of 910x2100 mm.
Pros of using standard size doors
If the height of the doorway of the entrance door in the apartment is standard, then you can buy a ready-made entrance door. It will be much more profitable financially. Since you don’t have to order the production of a door block based on individual measurements. And installation of a standard design will be easier. There is no need to change the dimensions of the passage. The standard dimensions of the entrance door allow you to easily and quickly replace worn parts of the structure (door frame or leaf). There is a wide range of such doors available on the market. There will be no difficulties in choosing the appropriate model. Therefore, you should think carefully before deciding to order a door of non-standard dimensions. Perhaps such a design will look original and interesting. But a number of problems may arise later. It’s not for nothing that standards establish certain requirements and make recommendations. The approved dimensions of doors and openings are convenient and safe.
Features of various payment systems
The Russian market offers goods produced within the country and imported from abroad.
Manufacturers use two different systems of measures:
- English. Manufacturers use a foot, which is 30 cm 48 mm.
- Metric. In this system, meters, centimeters and millimeters are used to designate measures of length.
To select an entrance or interior unit, you need to take into account the measuring system used by the manufacturer of the selected product.
The standard height of the finished structure according to the English system is 6 feet 8 inches, in metric it will be 203.20 cm, width - 2 feet 9 inches, in the figures familiar to a Russian it corresponds to 83.82 cm.
Most of the products supplied from abroad to Russia are made by manufacturers using English feet for measurements.
Products made in the country are marked and measured in lengths familiar to Russian consumers.
The size of the doorway for the entrance door in a private house does not correspond to standard sizes
It happens that the doorway does not correspond to the values established by the standard. Owners of private houses often face this problem. After all, such buildings are usually erected without taking into account building codes and recommendations. Fortunately, the problem can be solved. The passage can be expanded or reduced if necessary.
How to widen a doorway
The easiest way is to widen the passage for installing a door. There are different methods for doing this work. All of them can be combined into three groups: rough, dry and wet.
Rude
The rough method is often used to independently expand the passage under the door. To implement it, use a sledgehammer and a hammer drill. A passage line is drawn on the wall. A series of holes are made along it with each other. Concrete couplings are knocked out with a hammer or sledgehammer. Next, the excess part of the wall is carefully removed. The fittings and rods are cut with a grinder.
Dry
You can also widen the opening using a diamond disc. They cut out the excess part according to the previously applied markings. Since the method is dry, a lot of dust is generated during its implementation. You need to work with the tool intermittently to avoid overheating and failure. It is better to trust such work to professionals.
Wet
The wet method of expanding the opening is the fastest and easiest. Many people choose it today. After all, it allows you to quickly create an opening of the required dimensions. The edges are smooth and do not require further processing. To implement this method, a special station with a diamond disk and a water supply system is required. Due to the jet of water, dust does not form during operation and the process itself becomes shorter, since there is no need to take breaks. Water cools the equipment. But to implement the wet method, you need to contact professionals. They have the required equipment, clothing, skills and experience. Therefore, the work will be done efficiently and quickly.
How to reduce the passage
If the opening is too wide, you can reduce it. For this purpose, laying is carried out in blocks. These can be blocks of cellular concrete, brick, cinder block. This option is perfect for the front door. As for interior partitions, they are narrowed by using aerated concrete and foam blocks. These materials are easy to cut and lightweight. But they differ in their ability to absorb moisture. Which is not particularly good for passages to the bathroom and kitchen. You can also narrow the opening using cement mortar.
Mounts the box
For installation you will need a drill, cutters, a hacksaw, wedges, bars, a miter box, polyurethane foam, a level, self-tapping screws, a pencil, and nails. The slopes are checked before installation, the dimensions of the box are determined vertically and horizontally in 3 places. If there is a difference of 5cm or more between the parts on one side, then the walls need to be further aligned. In this case, the width of the door frame of the interior door should not be close to the walls; leave a small gap.
When assembling a box without experience, it is better to use parts that are secured at 45 degrees. You need to make recesses in the fabric for the loops. It is important to make them in the middle so that a distance of 18 cm is maintained at the top and bottom. After marking, holes are made for the hinges. Then screw the hinges, selecting a drill of equal diameter to the fasteners.

Next the canvas is screwed on. It is necessary that the thickness of the interior doors be smaller or equal to the frame. After drilling the doors, make holes for the handles and the lock and install them.
All that remains is to insert the box into the opening. Moreover, the installation can be done if the thickness of the interior door frame does not exceed the width of the walls. When you have inserted the box and additional boards (if necessary), you need to foam the empty spaces. Do not rush to fill completely empty spaces, because as the polyurethane foam hardens, it expands.
If during installation the platband does not reach to cover the edge of the upper wall, then you need to choose wider platbands or shorten the opening. Otherwise, if the opening is too small, you can trim the wall to expand the space, but this is difficult. It is easier to trim the sashes, but this can ruin the strength. Therefore, they often act according to a complex option.
