Standard dimensions for interior doors and openings

Doors - one of the most significant elements of the design of any room. Through them the entrance, exit from the house, apartment, office is made, therefore this element wears out quickly, demanding replacement. The standardized dimensions of interior doors simplify the task of selecting a door leaf that fits in size. The doorway to any room is made with a regular or double-wing product. Design, manufacturing material, as well as thickness, vary widely.

Basic functions, purpose

Replacing the existing door is made in the overhaul or cosmetic repairs. Dimensions of the structure are not always possible to “fit” with quality under the existing opening, the latter is even more difficult to fix. The front door protects the apartment, the house from unwanted visitors and thefts, the interior products have slightly different functions.

  • the door to the bathroom, the toilet allows you to wash without outside observers, quietly do other things;
  • in the kitchen, it does not allow smells of cooking to spread around the apartment;
  • the bedroom, the nursery with the help of well-chosen doors are protected from drafts, extraneous noise, light, penetrating from other rooms;
  • with the help of doors, the space is divided into separate zones, the area of ​​the room is delimited, depending on its purpose;
  • decorative function is to maximize compliance with the chosen interior style, harmonious combination with the surrounding background.

The door design can be different in height, width, made out transparent, frosted, patterned, stained glass or be completely "deaf". Interior fixtures are made of natural wood, chipboard, plastics, glass, MDF, and simultaneously several materials.

GOST requirement for interior doors, openings

State standards define the optimal dimensions of interior products, taking into account the width, length, thickness of doorways. Manufacturers usually adhere to these frames, but on order create items with any dimensions. Their cost is negotiated individually, exceeding the usual by 20-50%. Most often this is done during redevelopment, as well as in private homes.

The basic requirements for doorways are:

  • when the canvas is open, there should be no obstacles to the passage of a person, evacuation;
  • the width is sufficient to allow passage, carry a stretcher, other means of transportation, if necessary;
  • according to fire safety standards, the height of the opening should be from 1.9 m., width - from 0.8 m.

Before installation, it is necessary to study the current norms of SNiP, believing whether the purchased item corresponds to them. It is necessary for high-quality installation, convenient, safe use by all family members.

Uncontrolled redevelopment, illegal expansion of openings, entail the imposition of heavy fines, as they are able to "weaken" the structure of the building, leading to its collapse.

Door marking

Marking of door structures located between the rooms is defined according to the table:

  • DU - enhanced;
  • DHA is moisture resistant;
  • TO - glazed;
  • DG - deaf;
  • DN - outer chain, input;
  • DGUT - insulated;
  • FGD is smoke-tight;
  • DV-1 - interroom internal;
  • DV-2 - internal entrance apartment;
  • DV-3 - internal entrance to the premises of public buildings;
  • DV-4 - internal entrance to a public building, equipped with a security alarm system;
  • DV-5-internal for the staircase;
  • DV-6-internal for bathrooms;
  • DV-7 - chained inner;
  • DV-8 - shed construction;
  • DV-9 - other internal;
  • DL - manholes, hatches;
  • DS - special;
  • PN - outer outer packaging;
  • PV - inner lining;
  • PS - special unboxing cloth;
  • PL - canvases for roofless hatches, manholes.

There are various compilations of the above markings - DNDG, DNDDG, DV1DDG, DV3DO, DV9DDO and others.

Dimensions of interior doors

Dimensions of door structures in a large range differ for single and double models. For different rooms, their standard parameters are:

  • kitchen room - 70 cm by 200 cm;
  • bathroom, toilet, combined bathroom - 60 cm by 190 cm;
  • living rooms - 80 cm by 200 cm.

The threshold height is calculated separately, although it is not always mandatory, it should be present only in the bathroom, toilet, at the entrance structure.

Opening dimensions

Parameters required by state standards are strictly regulated. The height of the opening - 2060/2090, 2160/2190 or 2260/2290, width - 630/650, 680/700, 780/800, 880/900, 980/1000. The width of the opening for the double leaf - 1280/1300, 1480/1500, 1580/1600. Standard depth of an interroom opening is 7 cm for rooms of a bathroom, kitchen, from 7 to 20 - for living rooms. Below, between the canvas and the floor, it is necessary to leave a gap: under the kitchen door - 15-19 mm, under all others - 4-12 mm, on top - 3-4 mm.

Box dimensions

The door frame is made proportionate to the canvas, exceeding its parameters within certain limits. The box is usually sold complete with a door, forming a door block. The size of the gaps between the canvas and the box is 3-4 mm on each side. This distance is necessary for easy closing-opening, fastening on the loop.

When the size of the door leaf is 550 by 1880 mm, the door frame unit will be 615 by 1923 mm, the desired size of the opening is 635 by 1935 mm, the external dimensions of the construction with platbands are 750 by 2000 mm. When the door has dimensions of 600 by 1900 mm, with a box it will be 665 by 1943 mm, the opening will be 685 by 1955 mm, with platbands 800 by 2020 mm and so on, respectively. General parameters of height from the floor: if the door is 200 cm, with a box it will be 207 cm, and at 230 cm - 237 cm, etc.

Canvas dimensions

According to the standard, the height of the leaf of any door is 2000, 2100 or 2200 mm, the width of a single structure is 550-900 mm. Double-leaf products are available in widths of 1200, 1400, 1600 mm. Outbuildings such as a pantry, dressing room can be equipped with doors, 50 cm wide, if it is convenient for residents.

If earlier, during previous repairs, the dimensions of the opening were corrected, the standard construction would be unacceptable for it - you will need to use an additional input extension or sufficient for high-quality installation.

Thickness is dense

The thickness of the interior door leaf depends on its purpose, the design of the object, the surrounding room, the thickness of the walls. Wooden paneled enough massive, made of plywood or laminated chipboard have a thickness of 30 mm. The level of sound insulation of a particular room, the strength of the product, its durability, and overall appearance depend on this parameter.

Suspended, sliding structures can have a thickness of about 20 mm, the original design - 35-45 mm. Products with a thickness of 55-65 mm look solid, expensive, but in apartments with excessively thin walls are inappropriate. Doors, made almost entirely of tempered glass, will be 8–13 mm thick, they look stylish, elegant, and the box is standard.

When the door frame is larger than the wall thickness, additional finishing is used, in the form of specially prepared slats, forming a portal.

How to make measurements of the opening

To determine what size the product is required, invite a professional measurer or do the work yourself. In order not to be mistaken with the final result, it is necessary to consider whether the floors are already installed or not. In the latter case, it is required to know the thickness of the planned flooring, how much to leave for free opening-closing.

How to measure:

  • measurements are made with a metal tape measure with a wooden, plastic meter, but not with a soft measuring tape;
  • the measuring device must be kept as horizontal as possible to obtain accurate width parameters, strictly vertically - when measuring height;
  • the door block is completely removed, cleared of plaster, other materials of finishing, so that the contours of the entrance were as clear as possible;
  • width is recommended to measure in three or four different places - from below, above, in the middle;
  • the height is obtained by measuring from the floor level to the upper points of the passage, also in two or three places;
  • the thickness of the walls also matters - they are measured in different places of the vertical, horizontal slopes.

Calculations of the proportion of the door frame to the opening

According to the SNiP, the ratios of door panels with the box are as follows:

  • 6 to 0.76;
  • 7 to 0.87;
  • 8 to 0.97;
  • 9 to 1.1;
  • 2 to 1.3;
  • 4 to 1.5;
  • 5 to 1.6.

There are other parameters: in brick buildings, with a height of 2.25 m, a concrete lintel above the doors is at a height of 1.88 m, in monolithic buildings - 1.87 m, in timber, with a ceiling height of 1.97 m, the lintel is mounted 1.85 m from the floor.

When the thickness of the opening is much larger than the box itself, its perimeter, except for the bottom, is formed by the slopes of the type that is suitable for the style.

Sizing double doors

Double doors can be either sliding or hinged. Most often they are installed in the living room. The most common parameters of double structures: the width of each sash - 65 cm, height - 230 cm. The width of the valves can be unequal: 40 plus 90, 40 plus 60, 50 plus 70, 55 plus 80, etc. The opening itself can be 100, 110 , 120, 130, 135, 150 cm. The width of the box with 4-6 cm.

In the one-and-a-half constructions there are also two doors of different widths - the smaller one opens extremely rarely, only in order to bring large-sized furniture, household appliances, etc. The width of the opening for them is 1310, 1510, 1550 mm, height - 2070-2370 mm The thickness depends on the specific model, there is no special marking. The shape of the product is arched or rectangular.

Variety of door designs

The minimum and maximum parameters of typical doors between rooms are specified in the standards, and there are several variants of the design itself. It consists of linen, hinges, boxes, upper crossbar, lock with handle and mate. The threshold is not provided everywhere - its presence is often inconvenient. The doors for built-in wardrobes, including the "coupe" type, are made as thin and smooth as possible so as not to clutter the room. Balcony have transparent glazing, mounted as tightly as possible, protecting the room from the cold from the street.

The modern choice of interior models allows you to decorate the premises of any interior style. The dimensions of the product should correspond as much as possible to the area of ​​the room in which they are installed - wide, high in small rooms are inappropriate. The color of the door is most often chosen to match the floor, baseboards, coinciding with or sharply contrasting with the walls. Wooden products with a panel are suitable for classic style, glass products are minimalist, from MDF are modern, rough, frayed, artificially aged are for a loft, plastic will decorate pop art style, metal looks best in modern hi-tech style.

Door constructions are made "left" and "right", differing in the direction of opening. In each case, the most convenient option is chosen. The door should close easily, do not open spontaneously from the light movement of air, do not creak, do not jam. Accessories begging for a certain style of the interior, giving the product integrity, perfection.
By the way of opening-closing, they distinguish between sliding (considerably save space), cassette (part of the wall will have to be disassembled under them), folding ("accordion", intended for wide openings), "swinging" (opening in both directions) options.

When there are several doors in one room, all of them are designed in the same style.

Conclusion

Interroom, entrance, other doors are very different, intended for openings of different depths, in general, having parameters standardized by GOST. The dimensions of all openings are planned at the construction stage of the building, before the start of the finishing work, but sometimes you have to pick up the door later. The width of the product is indicated on the room layout, the height depends on the ceiling level. Installation of door structures is done by hand or with the participation of invited specialists.
