Interior doors will become a real decoration of the interior, if you choose their dimensions, design and configuration. Particular attention when buying should be given to the size of the canvas, box, as well as the opening itself. In most homes, these interior elements are created in accordance with the standard. Therefore, the stores also feature a large selection of designs with similar dimensions. Standards for interior doors will be discussed later.
The need for proper 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, safe. Knowing the standards of interior doors, you can correctly choose the 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 will be smaller than the opening, you will need to further process the opening. If the size is larger, you will need to cut an opening in the wall. This is pretty problematic.
In the process of choosing a door, not only the size of the opening, but also the boxes, the dimensions of the canvas itself are taken into account. To prevent errors, the measurement procedure is performed several times. After that, the obtained value is checked with standard indicators. Correct interior doors meet 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, not always when creating a private house adhere to established standards. 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 boxes and canvas. It will cost much more. Therefore, when building a house, you need to adhere to established standards. This will save many problems in the future.
Functionality
Interior wooden doors may vary slightly in size depending on their functionality. Width and height in this case may vary. In this case, the product will still be within the standard.
It is worth noting that for a hall, a hall or a living room, quite dimensional interior doors are required. This requires even the style of the interior. Dimensional doors give the room pathos, a special charm. For a bedroom or a child’s room, it’s quite possible to create narrower openings. However, they must allow furniture to be brought into the room. Therefore, for such rooms openings of medium size are created.
For the pantry, dressing room, as well as for rooms for utility or office purposes, the narrowest doors are suitable.
There are many varieties of designs. Sashes can be made of 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 efficiently.
The standard for the opening of the interior door remains unchanged for all types of construction. That it should be properly 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 GOST and other standards are taken into account. In this case, picking up the canvas and box will be much easier.
Some 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 to select materials for installation. Initially, you need to qualitatively measure the opening. From this indicator it will be possible to build on further.
The opening is always a few centimeters larger than the structure itself. If necessary, a correction is carried out. For this, drywall, beams or other suitable materials are placed between the opening and the box. This must be taken into account when calculating the maximum weight of the structure. The choice of accessories for interior doors in this case is also important. If you add additional materials, since the gap between the opening and the box is significant, do not purchase heavy structures.
It is necessary to pay attention to such an indicator as thickness. At the same time, the features of the interior partitions are taken into account. Their thickness should approximately coincide with the dimensions of the box. Otherwise, you will need to install add-ons. They compensate for the lack of dimensions of the box.
Choosing the dimensions of the box, it is still not worthwhile to purchase a design that will fit right next to the opening. Technological clearance should remain. It will be possible to blow it out with foam (if it is not too big), and then close the 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, box and the canvas itself. You need to understand that these dimensions are slightly different. Do not confuse the standard sizes of the boxes of interior doors and the canvas itself. There are also certain requirements for the latter.
The height of the standard canvas is 2 m. However, some deviations are acceptable. Canvases from 1.9 to 2.1 m may exist. The height of the interior doors according to the standard cannot be less or more. It should be borne in mind that between the sash and the floor there must be sufficient distance for movement. Many designs provide for installation of a nut. Its height also needs to be considered when choosing the height of the canvas.
The width of the door is selected in accordance with the design features. On sale are single, bivalve varieties. For a living room, the standard width is 70-80 cm. For some rooms (bath, toilet), this figure decreases to 60 cm. There are other standards for entrance doors.
No less 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 for 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.
Double-leaf constructions
The doors look stylish in the interior . There are also certain standards for them. The width is taken 1.5 or 2 times greater than for single-wing models. The height of the 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 double door. The width of the door leaf according to the standard is selected in accordance with the established standards for such structures. This takes into account the width not of the canvases themselves, but of the box as a whole. It should have dimensions from 1.2 to 1.5 m. This is the standard for two-wing 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 may have a size of, for example, 45 cm. The second leaf should be at least 70 cm wide. In general, the width of the entire door will meet the standard. The second sash is opened in rare cases, for example, when you need to bring dimensional furniture into the room.
If the wings are the same width. This allows you to increase the permeability rate in the room. The door looks interesting, aesthetically pleasing. It fits well with many interior styles. Similar designs are installed mainly in large-sized 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 the living room can vary significantly. This is due to the features of the operation of the room. To avoid making 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 was 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 harmoniously in a small kitchen. If such a room is large, then the width is increased to 80 cm.
For living quarters, the sash should not be too narrow. Its standard width is 80 cm. The height remains the same. She is 2 m.
The smallest designs are used for bathrooms. The width of the canvas can be as little as 60 cm. In some cases, the standard allows this figure to be reduced to 55 cm. The height can also be slightly less. It is 1.9 or 2 meters.
Measurement procedure
Replacement of the box of interior doors is carried out only after careful measurement of the opening. There is a certain technology for carrying out 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. A threshold is provided for in the design. Its height is 2 cm.
To calculate the width of the doorway, you need to add the width of the canvas, two thicknesses of the box, the mounting gap and two door blocks. The calculation will be as follows:
WB = 70 + (2 × 3) + 1 + (2 × 2) = 81 cm.
The door presented on sale is suitable for such an aperture. If it is smaller (does not meet the standard), it will need to be expanded. You can also determine 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.
Having examined the presented methodology of calculus, you can correctly select the size of the canvas in accordance with the dimensions of the opening.
Measurement
Before going to the store, you need to correctly measure the opening. Then it will be possible to choose the optimal size of the box and canvas. It is also worth considering one nuance. There is no standard for the thickness of the interior door. 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 a living room, 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, you will need to make a door to order. If the depth of the opening is less than that provided by the manufacturer, it is possible to compensate for the discrepancy with the help of extras.
It is important to make the correct measurement of the dimensions of the opening. First, its height is determined. It is calculated from the floor to the top. If the opening is uneven, the procedure is carried out in the area of narrowing. In other cases, determine the middle of the opening from the bottom and top. Between these points the distance is measured with a tape measure or other suitable measuring instruments.
The width of the opening is also measured between the points set in the center. If there is a narrowing, the distance is measured at this place. Depth is measured several times. It is defined below, above and in the 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, we made a measurement. 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 of 55 × 190 cm in size will be suitable. If the height remains the same, but the width increases to 70 cm , you can buy a door 60 × 190 cm.
To establish a standard design for the kitchen (70 × 200 cm), the width of the opening should be in the range from 77 to 80 cm and the height from 205 to 208 cm. When purchasing a door for a room with dimensions of 80 × 200 cm, you should measure the opening. Its height should be from 205 to 208 cm, and width - from 87 to 90 cm. Sometimes for a living room a door is required a little wider. In this case, the standard provides that its dimensions will be 90 × 200 cm. With such dimensions of the door, the opening should be from 97 to 100 cm wide.
When choosing a double-wing 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 it is supposed to install such a door should be from 127 to 132 cm.
These are the most common door dimensions. When choosing a design, the presented ready-made solutions must be adopted. In other cases, it is necessary to carry out an accurate calculation based on the data presented.
What to do if a mistake has been made?
It is worth saying that even when making calculations, some owners of the house or apartment make a mistake. As a result, installation is much more complicated. In some cases, you can solve the problem. To do this, consider the advice of professional installers. This will avoid returning the door, as well as ordering it from the manufacturer on an individual project.
If the opening is a couple of centimeters smaller than the door frame, it can be carefully increased. To do this, drill a wall with a power tool. This allows you to expand them by several centimeters.
If the box is narrower than the thickness of the opening, you can purchase additional ones. They cover the open surface of the wall. It is important to buy add-ons 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 larger than the door frame. This situation occurs when installing the interior door in the opening of the bearing wall. In this case, the structure will need to be framed around 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 for a spacious room.
Having examined the existing standards for interior doors, you can choose the design in accordance with the existing opening. To make a mistake in this case will be almost impossible.
