The standard dimensions of interior doors must be known for the correct installation of the door in the opening. To date, no general standards have been established for manufacturers to comply with them. But there are building standards on the basis of which openings are made. From such indicators, the characteristics of the door will be determined.
Door marking
With product labeling, everything is quite complicated. Of course, there are specific standardized designations for designations, but in some cases, common standards may change due to the abundance of manufacturers. It often happens that designs made by identical methods and outwardly similar constructions can be named and marked in different ways.
First, we will deal with the standard GOST 6629-88, which applies to the manufacture of wooden interior doors for housing and public buildings. Based on the standard, the following markings are applied to products:
- Product type: P - cloth, D - team;
- Type of cloth: O - glazed, U - reinforced with continuous filling, K - swinging with glass;
- The width of the door structure with the box (dm). Additionally, the following symbols are indicated: P - product with a nut, H - with a weld, L - left-sided;
- Height (dm);
- Name of state standard.
In addition to complying with GOSTs, official model names, factory unique codes can be used..
Structures are classified according to several criteria:
- By placement in the facility - they are internal (interior) and external (input);
- According to the material, metal, wood, glass products and combined variants are distinguished;
- By filling the deaf panel there are glazed and deaf systems;
- By the number of panels, single, one and a half and two-floor options are distinguished.
Standard sizes of swing interior doors
Considering the dimensions of the internal doors with the box, you should consider the height, width and weight of the parts. First, the opening is examined, into which the box with the canvas will be inserted. Therefore, the initial characteristics are slightly increased. To adjust the main dimensions, you can use the bars, bricks or sheets of drywall.
Sizes of a cloth
If you do not apply non-standard approaches, where the dimensions of the opening for interior doors are tied to individual wishes, then the bulk of manufacturers are based on the indicators of the standard. The ratios of the indicators of the opening and door systems (panels and ducts) based on SNiP are indicated in the table:
№ | The indicators of the cloth, cm | Characteristics of the opening, cm | |
Width height | width | height | |
1 | 60*200 | 68-71 | 205-207 |
2 | 70*200 | 78-81 | 205-207 |
3 | 80*200 | 88-91 | 205-207 |
4 | 90*200 | 98-101 | 205-207 |
5 | 60*190 | 68-71 | 195-197 |
6 | 55*190 | 63-66 | 195-197 |
7 | 60+60*200 | 128-131 | 205-207 |
According to DIN standard, the ratio will be as follows:
№ | Door parameters, cm | Characteristics of the opening, cm | |
Width height | width | height | |
1 | 60*200 | 70-74 | 206-208 |
2 | 70*200 | 80-84 | 206-208 |
3 | 80*200 | 90-94 | 206-208 |
4 | 90*200 | 100-104 | 206-208 |
5 | 60+60*200 | 134-140 | 206-208 |
If we consider the parameters of any sliding and swing doors, each person provides for the width that he will use every day. But the state standard offers a door width for kitchens of 70 cm, bathrooms - 60 cm and residential facilities - 80 cm. On the market, designs for a bedroom are 90 cm wide, and for bathrooms - 55 cm.
It is worth mentioning about bivalve designs that allow you to emphasize the status of any room. Basically they consist of the same type (60 cm) or various paintings (60 and 80 cm wide). Of the narrowed options, manufacturers offer designs with sash widths of 40 and 80 or 40 and 40 centimeters.
The most common width of the paintings is 35 - 40 cm, but the indicator can vary up or down (based on the material used and the type of product). For example, the thickness of a sliding sash can be 2 cm, and wooden canvases can reach up to 50 cm.
In terms of height, manufacturers offer products of 190 and 200 cm, but there are also European standards - 210 cm. On request, customers can purchase products of greater height (up to the ceiling or 2.3 m). Often, designers adhere to foreign standards.
Fig. 3. The main characteristics of the doors
Box sizes
Ready-made options are on sale (with a box and accessories). This is a U-shaped design, which is placed around the perimeter of the opening. The system allows you to securely fix the panel.
The total height and width of the web with the box increases by 10-15 cm, but a gap should be left between the wall and the mounting point, so the parameters of the cloth should be less than the characteristics of the frame (to protect against abrasion). The thickness of the panel is compared with the size of the wall and box. Correctly mounted doors will be comfortable, organically look indoors, meet the standards used.
Based on the characteristics of the panel, for interior structures, indicators of the standard dimensions of the door frame of the interior door may vary. Therefore, it is desirable to purchase designs along with casing, frame and fittings.
For the manufacture of boxes used bars of various parameters. The width of the material can reach 1.5-4.0 cm, but the optimal figure is 3.0-3.5 cm. If you comply with the standards, you get a reliable design that lasts a long time.
The thickness of the box and the wall should match, but this indicator should not exceed the width of the opening. For wooden walls, the criterion is 10 cm, and for brick - 7.5 cm. Therefore, a box whose dimensions exceed the wall parameters cannot be firmly fixed. Otherwise, you can use special add-ons.
When manually assembling the box, the parameters of the vertical posts must be determined in accordance with the height of the panel, the thickness of the horizontal bar, the dimensions of the gap and threshold. The parameters of the horizontal bar are calculated according to the width of the door.
Aperture sizes
When creating partitions and walls, you can determine the width of the opening according to the standard, where the parameters of products with a frame and accessories are indicated. In this case, the width of the panel is folded with a double indicator of the frame and a bilateral gap. As a rule, it is equal to 1.5 cm. For example, 90.0 + 3.0 * 2 + 1.5 * 2 = 99.0 cm.
The height of the opening is also calculated: without a nut, it will be 200 + 3 + 1.5 + 0.5 = 205 (0.5 is the distance between the panel and the floor for air exchange, it can increase to 1 cm, and for a house with liquefied gas - up to 1.5-2 cm). If there is a nut, the height of the opening is determined by adding up the size of the opening and the web parameters, the width of the mounting seam and the box.
The thicker the canvas, the better?
Thick canvases well emphasize the design of the living room, made in the style of Baroque, Renaissance or Empire style, and movable partitions and thin screens will complement the openings of dressing rooms and pantries.With an increase in the thickness of the door, its mass increases, which increases the requirements for hinged fittings. Additional hinges may be required, which will increase the cost of construction. Therefore, the canvas should be selected for massiveness and other characteristics according to the feasibility, optimality.
There are many products on the market with leaf thicknesses of 30-40 cm. But the assortment has thinner sliding MDF partitions (about 2 cm). Tempered glass designs from 8 mm thick have recently become popular.
One and a half and double doors
The double swing doors with two wings will look effective in the design. The width of the products depends on the model and parameters of the passage of the living room. The parameters for such doors are sometimes taken with an increase of 1.5-2.
The standard sizes for double systems with a box are 120-150 cm. This allows you to put full-fledged double-wing designs. The width of double doors is 1-1.4 m.
With the minimum dimensions, double doors can be offered with one fixed leaf with a width of ½ or 1/3 of the standard value (for example, one and a half options). The other part of the canvas will be full. With the optimum width of the aperture, identical flaps are placed, which increases the aesthetics and patency of people.
Doors with hidden box
Compared to standard designs, doors with an inner frame have great advantages.
The dimensions of the opening must comply with the standards of the manufacturer of the door systems: the wall should be flat vertically, a deviation of 1 mm is allowed in height, and the wall thickness should not be more than 8 cm. The ideal gap width is 1.7-2 cm ± 1 cm (the gap at the bottom of the web 4 is considered optimal).
Custom Doors
The factories offer a large assortment of interior doors with ducts and fittings, including non-standard options. But there are cases of inconsistency of manufactured products to the existing opening. In this case, you can adjust by increasing or reducing the height and width to the desired indicator. An alternative solution is to order custom designs with custom sizes.
The cost of manufacturing doors for an individual order will be higher in comparison with the purchase of finished products. But this will allow you to realize interesting ideas. For example, you can put the door of the compartment.
How to measure the opening
If the door has a door sill, the length of the opening can be calculated by summing the height of the threshold with the parameters of the panel, box and mounting seam.
According to the standards, it is easy to know the width of the panel. For a 90-centimeter opening, a canvas 80 cm wide is suitable. This can be calculated as follows: 90-15 * 2-30 * 2 = 81 cm, and excess centimeters will be masked with platbands.
When determining the dimensions, it is better to take into account the gap that will remain between the panel and the box. But this figure is 1-2 millimeters, so with approximate calculations it can be ignored.
