Interior doors will become a real decoration of the interior, if you choose their dimensions, design and configuration correctly. When buying, special attention should be paid to the size of the canvas, the box, as well as the opening itself. In most houses, such interior elements are created in accordance with the standard. Therefore, the stores also offer a large selection of designs with similar dimensions. Interior door standards will be discussed next.
The need for correct calculation
Standards for interior doors are regulated by GOST 6629-88, OKP 53-6111 and 53-6121. This is necessary so that the partitions in residential and other premises are comfortable and safe. Knowing the standards of interior doors, you can choose the right type of product in accordance with the existing dimensions of the opening.
Before sending to the store, you need to make several accurate measurements. An error can result in additional costs. If you purchase a door whose dimensions are smaller than the opening, you will need to additionally process the opening. If the size is larger, you will need to cut an opening in the wall. This is quite problematic.
When choosing a door, not only the size of the opening, but also the box, the dimensions of the leaf itself are taken into account. To avoid a mistake, the measurement procedure is performed several times. After that, the obtained value is compared with standard indicators. Correct interior doors comply with the requirements of GOST and OKP. Such structures are installed in almost all multi-storey buildings. Also, during private construction, official companies apply official rules and regulations when creating openings.
However, when creating a private house, the established standards are not always adhered to. In this case, the openings may differ from the parameters regulated by GOST. In this case, it will be difficult to choose an interior door. The way out of this situation is to order a box and canvas. This will cost an order of magnitude more. Therefore, when building a house, you must adhere to established standards. This will save a lot of problems in the future.
Functionality
Interior wooden doors may differ slightly in size depending on their functionality. Width and height in this case may differ. In this case, the product will still be within the standard.
It is worth noting that a hall, hall or living room requires fairly large interior doors. Even the style of the interior requires this. Dimensional doors give the room pathos, a special charm. For a bedroom or a children's room, it is quite possible to create narrower openings. However, they must allow furniture to be brought into the room. Therefore, medium-sized openings are created for such premises.
The narrowest doors are suitable for a pantry, a dressing room, as well as for utility or service rooms.
There are many varieties of designs. The sashes can be made from a single sheet of material or have glazing. Sliding pendulum varieties are gaining popularity. Also, the sash can be folding or cassette. New design options allow you to save space in the room, use it more rationally.
The standard of the interior door opening remains unchanged for all types of construction. It is he who should be correctly measured before buying any design. Domestic and foreign manufacturers adhere to established standards. Experts recommend choosing products of Russian brands. In its manufacture, the norms of GOSTs and other standards are taken into account. In this case, it will be much easier to pick up the canvas and the box.
A few recommendations
Interior wooden doors are selected after measuring several indicators. It is necessary to correctly determine the height, width and thickness. The total weight of the structure is also taken into account. This is necessary for the selection of materials for installation. Initially, you need to qualitatively measure the opening. It will be possible to build on this indicator further.
The opening is always a few centimeters larger than the structure itself. If necessary, a correction is made. To do this, lay drywall, beams or other suitable materials between the opening and the box. This must be taken into account when calculating the maximum weight of the structure. The choice of fittings for interior doors in this case is also important. If additional materials are added, since the gap between the opening and the box is significant, you should not purchase heavy structures.
You need to pay attention to such an indicator as thickness. At the same time, the features of interior partitions are taken into account. Their thickness should approximately match the dimensions of the box. Otherwise, add-ons will need to be installed. They compensate for the lack of box dimensions.
When choosing the dimensions of the box, you still should not purchase a design that will fit right up to the opening. There must be a technological gap. It can be blown out with foam (if it is not too large), and then cover unseemly places with platbands. Installation of extensions and platbands on interior doors is almost always required.
Standards
There are certain requirements for the dimensions of the opening, the box and the canvas itself. You need to understand that these dimensions are slightly different. Do not confuse the standard sizes of interior door frames and the leaf itself. The latter also has certain requirements.
Standard canvas heightis 2 m. However, some deviations are permissible. There may well be canvases from 1.9 to 2.1 m. The height of interior doors according to the standard cannot be less or more. In this case, it is worth considering that there must be sufficient distance between the sash and the floor for movement. In many designs, the installation of a nut is provided. Its height must also be taken into account when choosing the height of the canvas.
The width of the door is selected in accordance with the design features. On sale are single-leaf, double-leaf varieties. For residential premises, the standard width is 70-80 cm. For some rooms (bath, toilet), this figure is reduced to 60 cm. There are other standards for entrance doors.
An equally important indicator is the thickness of the sash. This indicator is not selected individually. It completely depends on the type of material chosen, as well as the production features that are provided by the manufacturers themselves. The weight of the product depends on the thickness. This must be taken into account when planning the installation of the structure.
Two-leaf constructions
Double doors look stylish in the interior. They also have certain standards. In this case, the width is taken 1, 5 or 2 times more than for single-leaf models. The height of interior doors according to the standard in this case remains the same. It varies from 2 to 2.1 m.
Sashes can have a size of 70-80 cm each. This is a full size double door. Interior canvas widthdoors according to the standard is selected in accordance with established standards for such structures. This takes into account the width of not the paintings themselves, but the box as a whole. It should have dimensions from 1.2 to 1.5 m. This is the standard for double-leaf models.
In this case, the sashes can be either the same size or different. In this case, one side closes tightly, and only the second part works. The first leaf can have a size, for example, 45 cm. The second canvas must be at least 70 cm wide. In general, the width of the entire door will comply with the standard. The second sash is opened in rare cases, for example, when you need to bring bulky furniture into the room.
If the sashes have the same width. This allows you to increase the rate of patency in the room. The door looks interesting, aesthetically pleasing. It fits well into many interior styles. Such structures are installed mainly in large rooms with high ceilings. In this case, it is allowed to increase the height of the door by adding an insert on top. Such a bar allows you to compensate for the weight of the wings, distributing it more harmoniously.
Doors in different rooms
Standard interior doors in the bathroom and living space can vary significantly. This is due to the peculiarities of the operation of the premises. In order not to make a mistake when choosing, you need to know the standards for the doors of different rooms.
So, for example, for the kitchen in the official documentation it is established that the size of the sash should be 2 m high and 70 cm wide. A wide opening is useless here. A relatively narrow door will look harmonious in a small kitchen. If such a room is large, then the width is increased to 80 cm.
For a living space, the sash should not be too narrow. Its standard width is 80 cm. The height remains the same. It is 2 m.
The smallest designs are used for bathrooms. The width of the canvas can be only 60 cm. In some cases, the standard allows this indicator to be reduced to 55 cm. The height can also be slightly less. It is 1, 9 or 2 m.
Measuring procedure
Replacing the frame of interior doors is carried out only after a thorough measurement of the opening. There is a certain technology for this process. It is important not only to know the standards for the sash, but also to correctly correlate the measurement results with the existing dimensions of the box. For example, for a standard door in a kitchen with dimensions of 200 × 70 cm, a box 3 cm thick is purchased. At the same time, a mounting gap of 1 cm should remain. The door block is 2 cm. The design provides for a threshold. Its height is 2 cm.
To calculate the width of the doorway, you will need to add the width of the leaf, two frame thicknesses, a mounting gap and two door blocks. The calculation will be as follows:
SHP=70 + (2×3) + 1 + (2×2)=81 cm.
It is for such an opening that the door on sale is suitable. If it is smaller (not conforming to the standard), it will need to be expanded. You can alsodetermine the height of the opening. It is calculated as the sum of the height of the canvas, the threshold. Two box thicknesses are added to this value. In the presented example, the calculation will be as follows:
VP=200 + 2 + (2×3)=208 cm.
After considering the presented calculation method, you can correctly select the size of the canvas in accordance with the dimensions of the opening.
Measuring
Before going to the store, you need to correctly measure the opening. Next, you can choose the optimal size of the box and canvas. It is also worth considering one nuance. There is no standard for interior door thickness. However, there is a relationship between this indicator and the weight of the structure. This must be taken into account when choosing.
It is also worth noting that there is a standard for the depth of the opening. It is 7 cm. For residential premises, this figure can be increased to 20 cm. Almost all door frames are made in accordance with the standard size (7 cm). Therefore, if there is an opening with other dimensions, it will be necessary to make a door to order. If the depth of the opening is less than that provided by the manufacturer, you can compensate for the discrepancy with the help of extensions.
It is important to measure the dimensions of the opening correctly. First, its height is determined. It is calculated from the floor to the very top. If the opening is uneven, the procedure is carried out in the narrowing area. In other cases, the middle of the opening is determined from below and from above. The distance between these points is measured with a tape measure or other suitable measuring instruments.
The width of the opening is also measured betweendots set in the center. If there is a narrowing, the distance is measured in this place. The depth is measured several times. It is defined at the bottom, top and center. This allows you to determine where the widest part is.
Several standard solutions
Applying existing standards for interior doors, after measuring the opening, you can choose the appropriate design option. So, for example, wanting to replace it in the bathroom, they measured it. It was possible to establish that the width of the opening is from 62 to 65 cm, and the height is from 195 to 197 cm. It can be concluded that in this case a canvas measuring 55 × 190 cm is suitable. If the height remains the same, but the width will increase to 70 cm, you can buy a door 60×190 cm.
To install a standard kitchen design (70×200 cm), the width of the opening should be between 77 and 80 cm, and the height should be between 205 and 208 cm. When purchasing a door for a room with dimensions of 80×200 cm, opening should be sealed. Its height should be from 205 to 208 cm, and its width should be from 87 to 90 cm. Sometimes a slightly wider door is required for a living space. In this case, the standard provides that its dimensions will be 90 × 200 cm. With such dimensions of the door, the opening should be 97 to 100 cm wide.
When choosing a double-leaf design, it is also worth considering the requirements of the standards. Suppose you want to install a door of this type with dimensions of each leaf 60 × 200 (their total width is 120 cm). In this case, the opening in which such a door is supposed to be installed should be from 127 to 132 cm.
These are the most common sizesdoors. When choosing a design, the presented ready-made solutions must be adopted. In other cases, you need to make an accurate calculation based on the data presented.
What to do if a mistake was made?
It is worth saying that even when making calculations, some owners of a house or apartment make a mistake. As a result, installation is much more complicated. In some cases, the problem can be solved. To do this, you need to consider the advice of professional installers. This will avoid the return of the door, as well as ordering it from the manufacturer on an individual project.
If the opening turned out to be a couple of centimeters smaller than the door frame, it can be carefully enlarged. To do this, you need to drill the walls with a power tool. This allows them to expand a few centimeters.
If the box turned out to be narrower than the thickness of the opening, you can purchase extensions. They close the open surfaces of the wall. It is important to buy extensions that will fully match the color and texture of the box.
In some cases, it turns out that the thickness of the wall is much greater than the door frame. This situation occurs when installing an interior door in the opening of a load-bearing wall. In this case, the structure will need to be framed along the perimeter, except for the bottom, with an even slope. It is most often created from drywall.
Platbands allow you to hide all installation errors. Their width is selected in accordance with the characteristics of the door, the dimensions of the room. Narrow slats are suitable for a small room, and wide slats for a spacious one.
After reviewing existing standardsinterior doors, you can choose the design in accordance with the existing opening. It will be almost impossible to make a mistake in this case.
