Doing renovations in an apartment, country house or at the dacha, you want to have maximum coziness and comfort in your living rooms. It is achieved with the help interior decoration premises. Drywall is used for this, since the material is relatively cheap and easy to install.
At initial work With this material, it is necessary to keep in mind that there is a standard size of drywall (2500x1200x12.5 mm) and a non-standard one, and it is also advisable to know its weight and thickness. This information will help you purchase and cut finishing materials correctly.
What are the sizes of drywall?
Plasterboard sheets are available in the following sizes:
- The width of plasterboard can be either 600 mm or 1200 mm.
- Sheet length varies from 2000 mm to 4000 (in increments of five hundred millimeters).
- Thickness is: 6.5; 8; 9.5; 12.5; 14; 16; 18; 18.5; 24; 29 millimeters.
If you need other sizes of drywall and at the same time purchase a large batch of goods, the manufacturer will accommodate you and produce sizes suitable for construction.
Do not forget that drywall is puff paper with gypsum. Therefore, it works well in tension, but satisfactorily in compression. And this factor must be taken into account.
Types of drywall
There are several types of plasterboard sheets:
- GKL is a regular drywall used for finishing walls, ceilings and partitions in warm and dry rooms.
- VGKL - these sheets have a water-repellent and antifungal impregnation and are suitable for finishing rooms with high humidity.
- GKLO – fire-resistant plasterboard sheets, wide spectrum of action.
The most popular in construction are plasterboard sheets with a thickness of 12.5, 9 and 6 mm; 1.2 meters wide and 2.5 to 3 meters long. Work alone with large sheets uncomfortable. Another option is to purchase small sheets of drywall. But this increases the cost of the product and the number of joints that will need to be sealed.
The manufacturing company KNAUF has begun producing small-sized sheets, the size of which is 1500x600 mm. They are easy to install and transport. Perhaps the last thing you need to know is that when covering walls it is better to use sheets of plasterboard with a thickness of 12.5 mm, but if you need to bend plasterboard, for example for arches, then 6 and 9 mm.
You also need to take into account that in small construction stores you can only find standard size drywall. Therefore, before starting repair work make a calculation building materials and buy everything at once in construction supermarkets.

Drywall is one of the most popular building materials. The main advantage of the material is that its use allows you to expand the range of design solutions and create structures of various shapes, finishing walls and ceilings in any room. This article discusses the parameters that allow you to choose the right drywall: price per sheet, dimensions, thickness, purpose and others.
The size and price of a plasterboard sheet is determined by its size, thickness and the presence of additional characteristics
The main material that makes up a plasterboard sandwich is gypsum. It is a natural salt that is formed naturally from sea water.
Construction of plasterboard sheet
In order to obtain plasterboard sheet (GKL), the extracted raw materials must undergo pre-processing, which includes two processes:
- burning. The temperature at which this process takes place is approximately 180–190°C;
- grinding
To make gypsum boards of the desired shape, a solution with water is mixed, and sometimes fiberglass is added. It is a component that significantly increases the deformation resistance of gypsum plasterboards, and also has a positive effect on fire-resistant properties. Cardboard is fixed on both sides of the gypsum sheet, which is environmentally friendly. Such cardboard is made from cellulose and impregnated at the production stage with special fire-retardant additives.
The size of the drywall sheet is selected based on the area that needs to be covered
Main types of plasterboard sheets
Depending on the purpose and technical features, all gypsum boards are divided into the following types:
- standard;
- moisture resistant;
- fire resistant;
- waterproof and fireproof;
- acoustic.
Standard and moisture-resistant plasterboard sheet 12 mm. Price per sheet and characteristics
Standard gypsum board is used when it is necessary to carry out interior finishing work. Using standard plasterboards, walls are leveled, and partitions, multi-level ceilings, etc. are installed. To calculate materials for finishing work, you need to know the length and height of the plasterboard sheets. The sheet dimensions are usually 2500x1200 mm. The cardboard of standard sheets is gray in color and is indicated by blue markings. Standard plasterboards are used in rooms with normal humidity.
With the help of drywall you can not only level the walls and ceiling, but also create complex designs by type of arches or niches
Moisture-resistant plasterboard sheets are used in rooms where the humidity level exceeds the permissible values. But its use is advisable only if the room has an exhaust ventilation system. In turn, the front surface of the sheet must be equipped with a waterproofing material (paint, primer, PVC coating).
The dimensions of the moisture-resistant plasterboard sheet are the same as those of standard plasterboards. Such sheets are used for the construction of slopes. GKLV in combination with waterproofing materials are used for covering work surfaces in rooms with increased level humidity. These include the bathroom.
Helpful information! Moisture-resistant drywall has increased strength; it can be used for finishing public premises.
It is easy to work with drywall sheets, following the advice and recommendations of specialists
The material includes various hydrophobic additives, thanks to which the sheet is able to absorb a minimum amount of moisture (no more than 10%). In this case, the sheet is green and is indicated by blue markings. The price and size of a moisture-resistant plasterboard sheet may vary. However, products of standard sizes (2500x1200x12 mm) cost from 295 to 395 rubles per sheet.
Fireproof, waterproof and acoustic plasterboard
Fire-resistant building products are used when it is necessary to finish a surface that is located in close proximity to a fire source (for example, the inner surface of a fireplace). This is exactly the option in which fiberglass is mixed, which makes it resistant to fire.
Fire-resistant sheets are used in rooms where the humidity level may be low or normal. In this case, the cardboard can be either pink or red. Gypsum plasterboard fireproof sheets are marked in red.
Moisture-resistant plasterboard is used for cladding structures, walls and ceilings in environments with high humidity levels
Waterproof and fire-resistant plasterboard sheet (GKLVO) has a high fire resistance coefficient and also has reduced water absorption. The combination of properties allows the use of such plasterboard sheets in baths and steam rooms. However, it can also be used for ordinary interior finishing work. Cardboard GKLVO sheet is distinguished by its green color and red markings.
Acoustic gypsum boards differ from other types in that they have a high sound insulation coefficient. This property allows this material to be used for finishing walls and ceilings in concert halls, dance studios, as well as rooms where sound recording is made. The main difference between acoustic plasterboard and standard one is that its surface has holes, with a cross-sectional area of approximately 1 cm. The reverse side of acoustic plasterboard is equipped with a coating that does an excellent job of absorbing sound waves.
Dimensions of drywall sheets: length, height and thickness
The standard length of gypsum boards is 2.5 m, and the width is 1.2 m. Also, the following sizes can be classified as standard lengths: 3 and 3.5 m. In addition to standard sizes, in markets and in hardware stores you can find plasterboard sheets, the length of which maybe 4 m. Sometimes there are sheets with a length of 1.2 m (small-sized). The sizes and prices of drywall are interrelated. For example, sheets whose thickness is 9.5 mm are cheaper than twelve-millimeter products.
Drywall of different thicknesses is used for cladding walls, ceilings and other types of structures.
The standard width of a plasterboard sheet is 1200 mm (1.2 m), however, there are products on sale for which this figure can be 2 times lower (625 mm). Such sheets will cost less.
As for the thickness of the gypsum plasterboard, the standard indicators include the following:
- 12.5 mm;
- 9.5 mm.
Deviation from the thickness standard is also a common practice. If necessary, you can purchase gypsum boards with a thickness of 6.6 mm. In this case, their weight will be much lower, as will the cost of drywall per sheet. There are also sheets with other thicknesses - from 8 to 24 mm, which allows you to significantly expand their operational area.
The standard thickness of plasterboard sheet is 12.5 and 9.5 mm
Differences between wall and ceiling plasterboard
The sizes of wall plasterboard in the form of sheets can be different, however, they are all considered standard. The length of wall gypsum plasterboard varies from 2000 to 4000 mm. The minimum width is 625 mm and the maximum is 1200 mm. The standard thickness of plasterboard, which is used for wall cladding, is 12.5 mm.
Note! For wall finishing, sheets with dimensions of 2500x1200x12.5 mm are most often used.
If it is necessary to sheathe walls in an apartment or house with high ceilings, then it is recommended to use sheets with the longest length (4 m). Thus, we can conclude that the dimensions of the plasterboard are selected depending on the specific situation.
Thicker plasterboard can be used for walls, but 9.5 mm sheets are usually used for ceilings in order to reduce weight ceiling structure
Drywall, which is used for installation on the ceiling, itself should be lighter in order to simplify the installation process as much as possible. For cladding ceilings, gypsum boards with a thickness of 8 or 9.5 mm are used. The minimum thickness allows for a reduction in the weight of the suspended ceiling, which in turn reduces financial expenses when purchasing profiles for fastening drywall.
The price of a plasterboard ceiling is significantly lower than in the case of installation wall material. If necessary, you can use the services of professionals, who on average charge about 250 rubles. per installation 1 square meter ceiling plasterboard. The price per m2 of installation of plasterboard on the wall and ceiling also depends on the complexity of the work.
Overview of the cost of installing gypsum boards:
The price per m2 of installation of plasterboard partitions is calculated depending on the number of layers of plasterboard (1 or 2), as in other cases. Thus, we can conclude that prices per sq. m. installation of plasterboard differ depending on the installation location, the complexity of the work (including the creation of shaped elements), the number of layers of gypsum material, etc.
Installation of ceiling plasterboard is carried out using self-tapping screws and a screwdriver
In order to answer a common question: how much do drywall sheets weigh, you need to familiarize yourself with the data presented below. The table below shows the dependence of the weight of gypsum boards on their dimensions.
Dependence of gypsum board weight on dimensions:
Note! The weight of a 12.5 mm plasterboard sheet is indicated for a reason. Such sheets are in greatest demand among buyers.

How much does drywall cost: overview of types and prices of different modifications
Every person who is planning to use gypsum plasterboard for the interior decoration of their house or apartment first of all needs to study how much a sheet of drywall costs. Prices that can be found on the Internet vary depending on the brands and sizes of gypsum boards. The price can be indicated both per square meter of material and per full sheet.
Today, there are quite different, in terms of cost, plasterboard sheets. If you wish, you can purchase very cheap products, the price of which will be no more than 150 rubles. per sheet. Inexpensive drywall will allow you to save on repairs, but you need to understand that when buying cheap material you should not rely on high quality products. After all, the quality of any building material directly depends on its price. You can buy drywall in sheets with high quality standards from 230 to 250 rubles. per piece
The additional properties or type of plasterboard sheet are indicated by the color of the surface of the material and its marking
As mentioned above, the price of this finishing material also depends on the manufacturer’s company. For example, the price of Knauf plasterboard is slightly higher than in the case of other brands. For example, the cheapest sheets from this German manufacturer cost between 220 and 240 rubles. per piece More expensive gypsum boards from the KNAUF brand can be purchased for 300–340 rubles.
Comparison of prices of gypsum boards of different brands:
Drywall: price per sheet with fire-resistant and moisture-resistant properties
The above prices are for regular plasterboard sheets. It must be remembered that standard plasterboards are not suitable for use in conditions of high humidity. The price for a sheet of moisture-resistant plasterboard of the KNAUF brand is 400 rubles with dimensions of 3x1.2x12.5 mm. Thinner sheets of moisture-resistant gypsum board can be purchased for 320–340 rubles.
Comparison of prices of gypsum boards of different brands:
The price per sheet of moisture-resistant drywall from domestic manufacturers is more affordable, due to the absence of the need for expensive transportation. But in order to purchase quality material, you need to pay attention to the price per sheet. Buy moisture-resistant drywall from domestic manufacturer possible for at least 300 rubles. (1 sheet).
Fireproof plasterboard has a red surface color and is used to increase the fire safety of rooms or structures

Profiles for drywall: sizes and prices
Today you can find different profiles for drywall. The sizes and prices of these products also vary. The thickness of the metal profiles from the German manufacturer KNAUF ranges from 0.5 to 0.8 mm. The ability to choose different thicknesses allows you to assemble frames that can withstand the required weight.
Metal profiles are designed to create a frame for plasterboard structures
Helpful information! Profiles for plasterboard at the production stage are equipped with anti-corrosion protection through galvanizing. This procedure makes it possible to enhance their strength properties and extend their overall service life.
Profiles can have different design, which allows you to create construction models of any configuration. Depending on the design features, all profiles are divided into several varieties.
Length of profiles of different types:
Rack profiles: description, use and prices
In the international nomenclature of building materials, such products are designated by the Latin letters CW. Such profiles are most often used for installation of metal sheathing. Metal laths necessary for fixing gypsum boards to false walls or ceilings.
The algorithm for using rack profiles is as follows:
- First of all, the rack strips are inserted into guides, which are fixed along the perimeter of the false wall (or ceiling).
- Next, the profiles are aligned in the desired plane.
The price of a drywall profile depends on the thickness, length and purpose of the product
The structure, made of profiles, is the basis for further installation of gypsum boards. The planks, which are of the rack type, are produced in a width of 60 mm and their height is 27 mm. The length of the rack strip can be different (from 2 to 6 meters).
If the length of the plank does not correspond to the specified purpose, then it is possible to combine two or more planks together into one profile. The individual planks are joined together using special locking elements. If desired, the planks can be connected in such a way that they are perpendicular to each other.
Such profiles may have different markings, depending on the manufacturer. The marking of the rack strips may be as follows:
- CD (KNAUF);
- PP (Gyproc).
Using drywall profiles, you can easily change the geometry of the room by mounting walls, arches or other structures
The price of a profile for rack-type drywall varies from 150 to 400 rubles per package. The price range is due to different brands of products, as well as dimensions. Packages most often contain a standard number of parts (12 pcs.).
Average cost of rack profiles:
Guide profiles
A profile of this type has the international designation UW. These products are made in the shape of the letter “P”. From the name we can conclude that such products are used as guide elements. When assembling the frame structure, racks or guides are fixed to them, after which the drywall is installed. Prices for guide profiles vary depending on the length of the product.
The guide profile is used for installation vertical stand for fastening plasterboard sheets
The width of the guide bar is from 28 mm, and the height is from 27 mm. The guide strips are fixed to the working surface using dowels. The length of the guide part can be different (from 2.5 to 6 m).
Average cost of guide profiles:
Ceiling and arched profiles
International designation ceiling profile-CD.Ceiling strips are used for quick assembly of frame structures, which are fixed to the ceiling and subsequently sheathed with gypsum boards.
The most commonly used dimensions of the ceiling profile are 60x273x3000 mm
The thickness of the ceiling strips varies from 0.45 to 0.55 mm. The standard length of the ceiling profile is 3 m. The most common ceiling strips have dimensions of 60x27 mm.
Average cost of a ceiling profile:
This type of arched planks differs from the others in that they have a curved shape. Arched strips are used to organize arched openings and other structures with complex shapes.
Such products are marked with the Latin letters CD and UD. When installing such parts, it is possible to bend them to the required radius. This possibility is realized due to the fact that the profile body of this type is equipped with holes and cuts at the manufacturing stage.
On the building materials market and in specialized stores you can often find ready-made (curved) profiles. The bending radius of such a profile can vary from 0.5 to several meters, and the length from 2 to 6 m. Profiles of this type have a fairly wide range of prices. You can buy a profile for arched plasterboard for either 30 or 200 rubles. Here the design feature of the part plays a very important role.
Arched profiles have a curved shape, resulting in an even curve of the arch.
Helpful information! It often happens that a profile with required radius and even straight arched models with notches are missing. In this case experienced craftsmen It is advised to make notches on a regular profile and make a bend of the required radius yourself.
Corner profiles
Products of this type are divided into two types:
- protective;
- plastering.
Plaster corner profiles are used to fix the corners of plasterboard structures
The first type of corner strips is used to protect the outer corners of plasterboard structures (for example, in doorways). The corner strip is fixed using plaster, which penetrates the profile holes and securely fixes it in the required position. The second type is also called beacons and is used when plastering walls.
Cost of popular models of corner profiles:
As a rule, when assembling plasterboard structures, experienced craftsmen try to use materials from the same company. For example, to attach Knauf brand plasterboards, Knauf profiles for plasterboard are purchased, of which there are many types and sizes. There is no point in using expensive drywall, but saving on the profile, because the durability of the entire structure depends on the quality and reliability of the parts for the frame. And in order not to exceed the budget limit allocated for repairs, you need to carefully calculate the amount of materials, choose the optimal size of sheets in order to minimize the amount of leftovers.
Drywall - modern installation material for internal cladding of walls and ceilings of buildings, installation of partitions, creation of volumetric architectural elements interior, such as columns, piers, niches. Subject to compliance with technical requirements for installation and correct selection materials, operational properties plasterboard structures are in no way inferior to analogues created from traditional materials. When choosing drywall, you should pay attention to parameters such as type and size plasterboard.
Types of drywall
A plasterboard board is a rectangular sheet consisting of gypsum covered with cardboard on both sides. Depending on the additives used in the manufacturing process of gypsum core and cardboard, gypsum boards various types acquire appropriate performance qualities.
Ordinary drywall (GKL)
This type of plasterboard is intended for interior decoration of rooms with normal humidity (living rooms, hallways, utility rooms). Wall cladding, single-level and multi-level ceiling structures, interior partitions, rectangular and round section and other architectural elements. According to European standards, such a sheet is covered with light gray or gray cardboard. There is a stamp on the back side (blue for most manufacturers) indicating the type of sheet.
Moisture-resistant drywall (GKLV)
This type of plasterboard is used for finishing walls and installing partitions in rooms with high humidity (bathrooms, swimming pools, kitchens), as well as for interior cladding of frame houses in low-rise construction. Special additives have been added to the gypsum core of the sheet to reduce moisture absorption, and paper layer treated with fungicidal impregnation. When purchasing, moisture-resistant drywall can be identified by the green color of the cardboard on the front side and a marking stamp (usually blue) on the back side.
Other types of drywall
In addition to the listed types of sheets, there is fire-resistant plasterboard (GKLO) - gray with red markings, as well as plasterboard, resistant to high temperatures, and moisture ( GKLVO) - green color with red markings. But such materials, as a rule, are not used in home renovation. They are used in public and production premises, as well as at other facilities with increased safety requirements.
Dimensions of plasterboard sheet
The method of application and performance properties of plasterboard depend, first of all, on such a parameter as thickness. In the assortment of most manufacturers you can find sheets with thicknesses of 6.5 mm, 9.5 mm, 12.5 mm.
Sheet 6.5 mm
This is a thin drywall that can be bent without tensing or dampening. It is used in the manufacture of architectural elements with a small bending radius, for example, for end parts multi-level ceiling, round columns of small diameter, arched niches. To give rigidity to the structure, the sheathing of such a sheet is made in two layers. This should be taken into account when calculating required quantity material.
Sheet 9.5 mm
According to installation technology, developed by the Knauf company, a 9.5 mm thick slab is used as an additional sheet when arranging walls and partitions with two-layer cladding. A 12.5 mm slab is used as the main sheathing, and then 9.5 mm plasterboard is fixed on top of it. Nine-millimeter sheet is not recommended for use as a single-layer self-cladding. Due to its small thickness, it can change geometry when there are changes in humidity in the room. As a result, the joints between the slabs will separate and cracks will form on the wall.
Sheet 12.5 mm
Both regular and moisture-resistant drywall are produced in this thickness standard. This is a universal plate that is used for mounting ceiling and wall structures, interior partitions, arrangement of door and window slopes. From a 12.5 mm sheet it is also possible to produce bent elements of large radius (more than 1.5 m). To do this, the drywall needs to be rolled with a special spiked roller, well moistened with a spray bottle and, while wet, bent according to the pattern.
In accordance with European standards, the width of a plasterboard sheet is 1.2 m. The length of ordinary sheets is 2 m, 2.5 m, 3 m (these figures may vary slightly depending on the manufacturer). Thanks to this, it is possible to select the optimal dimensions of the slab, depending on the parameters of the structure being built.
When choosing a drywall supplier, you need to find out not only the cost of the sheet, but also the prices for all the necessary components. And then calculate the average cost per square meter of the structure. Some sellers set deliberately low prices for sheets to attract buyers, but their profiles and fasteners are expensive. As a result, the price of the finished structure may be higher than the market average.
Standard sizes of Knauf drywall

Gypsum plasterboard (GKL) is one of the building materials that has practically no opponents. The durability, strength and excellent appearance of sheathed ceilings and walls, constructed boxes and partitions, and designer figured structures have been tested over years of use. When starting repair work, it is important to understand the types of gypsum boards and base your calculations on the dimensions of the drywall.

General information and characteristics of the main types of drywall
The material used in “dry” construction technology, the smooth surface of which is easy to paint, wallpaper and ceramic tiles, consists of a core with external cardboard reinforcement of both planes and edges along the length of the sheet. The core material is gypsum. To obtain certain properties of a plasterboard sheet, special additives are mixed into the gypsum.
For all brands, the mass distribution of constituent materials is within the following limits:
- 90%-94% – gypsum;
- 4%-6% – reinforcing cardboard;
- 1%-2% – other components and special additives.
In the nomenclature of most plasterboard manufacturers, the main types are sheet material are:
- GKL is an ordinary plasterboard sheet (can also be called standard, construction, basic). This is the most popular and widely used type of material for interior work in rooms with low humidity. Suitable for installation on all types of surfaces: vertical, horizontal, curved. A regular leaf can be easily identified by gray color cardboard layer. Standard size plasterboard for gypsum board sheets has the following parameters, mm: 2700 (length) x 1200 (width) x 9.5 (thickness).
- GKLV is a marking of moisture-resistant drywall, used in all cases as gypsum board, and also suitable for furnishing premises with an expected humidity of up to 85%. During the production of the material, hydrophobic modifiers and silicone granules are added to gypsum, which reduce moisture absorption. The surface of the gypsum board is treated with anti-fungus and mold agents. The resistance of the material to moisture is increased by additional coatings after installation: paint, ceramic tile, waterproofing layer, water-repellent primer, plastic panels. In addition to standard use, waterproof plasterboard is suitable for kitchens, bathrooms, insulated loggias, attic rooms, showers, and swimming pools. Cardboard color is green. 2500x1200x12.5 mm is the size of a gypsum plasterboard sheet, which is considered standard.
- GKLO - this is the designation for fire-resistant plasterboard sheet. Special additives for gypsum and impregnation of cardboard (of which there are several layers in this material) special compounds Allow material up to 20 min. withstand the pressure of an open flame. GKLO helps to protect walls and ceilings near fireplaces and stoves, in saunas, baths and boiler rooms, ducts with installed wiring, attics and other high-risk rooms. Fire-resistant sheets are in demand for organizing partitions and covering surfaces in offices and premises public organizations, at enterprises. When choosing, you should take into account the higher cost and weight of the material. Cardboard sheets have pink color shades. The standard size of a plasterboard sheet is the same as gypsum board.
Special purpose gypsum boards
In addition to the types of popular drywall considered, there is a line of panels special purpose. Here is a list of some of them:
- GKLVO - the material combines the qualities of moisture-resistant and fire-resistant plasterboard.
- GKLF – façade panels for cladding buildings, able to withstand the effects of atmospheric changes.
- High-strength gypsum board reinforced with multilayer cardboard and fiberglass.
- Designer (flexible) gypsum board with a thickness of 6 mm is suitable for covering arched openings and designer wave-like structures.
- Gypsum fiber sheets, with an admixture of cellulose fibers to gypsum, are suitable for outdoor work, installation of floor coverings, and work in damp areas.
GCRs are also produced that can shield X-ray radiation, provide additional noise and heat insulation for walls, and conduct heat well when covering underfloor heating systems.
According to the method of application they are distinguished wall plasterboard, acoustic, ceiling, arched, restoration, laminated. The dimensions of the ceiling plasterboard allow you to reduce the weight of the ceiling structure (due to the thickness of 8-9.5 mm) and save on elements of the frame system.
Dimensions of plasterboard sheets
Standard sizes of gypsum boards are not strictly required for use when construction work Oh. There are no restrictions in selecting the material of the most suitable sizes and characteristics. Each master makes a choice based on specific parameters and operating conditions of the premises. Therefore, the market, responding to demand, offers big choice drywall sizes. Product sheet dimensions may vary within the following limits:
- Length, m – 2-4.
- Width, m – 0.6 or 1.2.
- Thickness, mm – 6-24.
Helpful information! The most popular among households and professional craftsmen The dimensions of the plasterboard sheets are as follows: width – 1.2 m; length – 2.5-3 m; thickness – in the range of 6-12.5 mm. For independent work, especially when installing a whole sheet, the products are inconvenient. In this case, buying small-sized drywall helps out. True, the cost of the product itself and the entire complex of construction work will increase, because additional joints will have to be sealed.
When selecting materials and making preliminary calculations, a table of the main parameters of gypsum boards of well-known brands will be useful.
