Currently, the process of finishing a room is rarely complete without the use of materials such as gypsum board (gypsum board) and gypsum fiber board. Constructions made from these materials are not as simple as they seem at first glance. In addition to the finishing sheets themselves, for a device, for example, a ceiling, special metal profiles, connecting elements, hangers, screws and other small items are required. Therefore, calculating the cost and quantity of drywall, profiles and other materials for the ceiling of at least one room is a very troublesome and time-consuming task.
To speed up the process, and also so that you can decide whether you are within your budget, this calculator has been created. It is capable of calculating two types of premises:
- Type 1 - rectangular room (ceiling). Here calculated accurately quantity and cost of gypsum plasterboard (GVL) sheets, profiles and main elements required for installation. In addition, using this calculator mode, you can determine the dimensions of the profiles.
- Type 2 - room of any size. This is to a greater extent rough estimate. Here only the quantity and cost of drywall sheets are determined exactly. The quantity of the profile and other elements necessary for installation is calculated using average values (how much is required per 1 m2).
The calculator consists of three parts: a picture, a column where the initial data is entered and a column where the result is shown.
DrawingThe figure shows layout plans for profiles and sheets of gypsum plasterboard (GVL), a cross section of the ceiling and a diagram of the sheet. Only those parameters that are either specified or determined after calculation are marked on it. If you look at the drawing of type 1 and type 2, you will see that they are very different from each other.
Also pay attention to the layout of the sheets. It shows how to lay sheets correctly from the point of view of specialists. And it is correct to lay them in a checkerboard pattern.
Input data Type 1Number of layers - select the number of gypsum board layers you need for the ceiling. In order to avoid unwanted cracks, plasterboard sheets are sometimes mounted in two layers.
The length (L) and width (K) of the room are the dimensions of the room (room) along the ceiling.
GKL (GVL) sheets:
Length (A) and width (B) are the dimensions of a sheet of drywall or gypsum fiber sheet.
Price per 1 m2 - the cost of the sheet, if it is indicated in square meters. m.
Price for 1 piece - the cost of the sheet, if it is indicated for one sheet.
Guides:
Most often, UD-28 or PN-28 profiles act as guides mounted around the perimeter of the ceiling.
Length - length of the profile upon purchase.
Price for 1 piece. - cost of one profile.
Main profile:
This is a load-bearing profile, which in most cases is attached perpendicular to the long wall of the room. Usually it is a profile CD-60 or PP-60.
Profile length - length before cutting, i.e. at the time of buying.
Profile pitch (P) - what is the main pitch with which this profile is supposed to be mounted. Typically it is 600 mm.
Profile width - for CD-60 and PP-60 it is 60 mm.
Price for 1 piece - the cost of one profile.
Jumpers:
A jumper is a profile installed across the main profile. Their length is determined by the pitch of the main profile (P), the width of the profile and the gap for ease of installation (usually 5 mm). Both CD-60 and PP-60, and UD-28 and PN-28 can be used as jumpers. In other words, the profile width can be taken smaller.
Profile length - what size the profile will be purchased.
Profile pitch (E) - the step with which this profile will be installed. Most often it is 600 mm.
Price for 1 piece - the price for which one profile is purchased.
Crabs and pendants:
The crab is the connecting element of the profiles. In other words, it connects the main profile with the jumpers.
The suspension is the element on which the entire ceiling rests. Usually it is installed on the main profile with the same spacing as the jumpers (E) are mounted - see figure.
Only the price for 1 crab and 1 suspension is indicated here.
You can get acquainted with the type of profiles and other elements for structures made of gypsum plasterboard (GVL), and find out their approximate consumption.
Type 2Here everything is the same as in type 1. Only the length and width of the room are not indicated, but the area (S) at once.
Also included in type 2 is a parameter such as perimeter (P). For example, for a picture it is equal to P=L1+L2+L3+L4+L5+L6+L7.
The profiles are designated for clarity. And the defining parameters remained only the length of the profile and its price.
ResultThe calculated values appear in this column immediately after clicking on the "Calculate" button.
Type 1Floor area - ceiling area.
GKL (GVL) sheets:
Number of sheets - the required integer number of sheets of size AxB.
Cost per 1 m2 and per 1 piece - the cost of the required number of sheets, depending on what the price was indicated for.
Guides:
Quantity - the required number of guides of a given length.
Price - total cost guides.
Main profile:
Length - the length of the profile, which is equal to the width of the room minus 5 mm for ease of installation.
Quantity - the required quantity of a profile of a given length.
Distance (X) - if you do not want to divide the length of the room into equal parts, by which the location of the main profile will be determined, but want to take a certain value, for example, 600 mm, then most often there will be a distance between the last profile and the wall that is not equal to the step. This is the distance X.
Cost - the total cost of the required number of profiles of a given length.
Jumpers:
Lengths Dl1, Dl2 and Dl3 are the dimensions of the lintels located between the main profile and the wall, the main profile and the main profile.
Number of Dl1, Dl2 and Dl3 - the required number of lintels for the ceiling with lengths Dl1, Dl2 and Dl3.
The total quantity of a profile is the required quantity of a profile of a given size, which is then sawn into Dl1, Dl2 and Dl3.
Distance (T) is the same as distance X for the main profile, only here for the jumpers.
Cost - the total cost of a profile for lintels of a given size.
Crabs and pendants:
The number of crabs and hangers is the required amount of these elements for the ceiling. Moreover, I would like to note that the suspensions are not taken into account at distance Y, since it can be different. For example, why hang a suspension there if Y=100 mm. Therefore, if you want to place a suspension in this place, then these new suspensions must be added to the resulting value.
Cost of crabs and hangers - the cost of the estimated number of crabs and hangers.
Total cost - it consists of the cost of sheets designed for 1 piece, the cost of profiles, crabs and hangers.
Type 2In type 2, almost everything is the same (depending on the initial data), only here you can also find out the number of others Supplies in addition to gypsum board (GVL) sheets, profiles, crabs and hangers. These are the so-called additional little things: screws, dowels, anchors, etc.
Also note that here one PP-60 profile acts as the main profile and jumpers.

Working with this tool comes down to taking simple measurements that even a person who does not understand repairs can handle, and entering them into a simple form.
The advantage of remote settlement
Calculating a plasterboard ceiling using a calculator does not require any special skills, it is easy and understandable for anyone common man who decided to start renovating his apartment. Those who have the opportunity to use the calculation can at any time convenient time change parameters and generate results by pressing the calculate button.
The vast majority today use a calculator for calculating plasterboard on the ceiling when solving repair problems. This choice is very justified, since contacting a specialist requires time and money, but with a calculator you get the finished result instantly.
That is why the decision to use such a tool for calculation will be more than correct, accessible to everyone.
Where does apartment renovation begin? From procurement planning. no exception: we have to purchase a profile for its fastening, screws, hangers and plasterboard sheets. The topic of our article is the calculation of plasterboard ceilings.
Let's start with the ceiling frame. It is traditionally assembled from a special galvanized profile.
Please note: in dry rooms without the slightest fluctuations in humidity, it is possible to assemble the sheathing from a bar and lath. Wood will somewhat simplify the installation of the frame, but if you are flooded by your neighbors or the weather is simply damp for several days, the frame may become deformed. It's better not to take risks.
Ceiling frame Profile UDThe total length of the mounted profile will be exactly equal to the length of the perimeter of the room. Of course, when purchasing, we will have to round the footage we received to a multiple of the profile length.
On sale you can find both three- and four-meter UD profiles. It is better to decide which option to choose based on the size of the room (this article discusses this issue). Obviously, with a room width of 380 centimeters, it will be more convenient to cut a four-meter profile than to add an 80 cm piece.
There are two main ways to install CD ceiling profiles:
- In the first case, a continuous sheathing is made with cages in increments of 60 centimeters over the entire ceiling area. In this case, the junction of two sheets of drywall must necessarily fall on one profile. However, even if you miss, it doesn’t matter: just place a section of profile of the required length under the seam on top.
- In the second case, the profiles are laid only in one direction, along the length of the sheets. The pitch is reduced to 40 centimeters, but the transverse profile is located only at the junction. It can be either attached to the frame or attached only to sheets.
How does this affect our calculations?
- In the first case, the total length of the profile will be equal to L*(H/0.6-1) + H*(L/0.6-1) meters, where the length and width of the room are indicated in Latin letters. For example, for a room 4*5 meters, the profile length will be: 5*(4/0.6-1) + 4*(5/0.6-1) = 57.(6) meters.
Of course, we will inevitably have a large number of scraps. Therefore, the profile is usually purchased with a margin of about 20 percent, which in our case will be about 70 meters (with a strip length of 4 meters, rounded up - 18 profiles).
- In the second option, the mounted profile will have a length equal to L*(H/0.4-1); however, several additional profiles will go to the joints between the sheets. In our case, the profile that will initially be mounted on the ceiling has a length of 5*(4/0.4-1) = 45 meters.
The calculation is simple; But when planning, we do not optimally use profile dimensions. Remember - we have 4-meter-long planks at our disposal. Isn’t it wiser to mount them across the room, where you don’t have to splice a long profile from several pieces?
Let's recalculate: 4*(5/0.4-1) = 46 meters. At the same time, we avoided the need to cut profiles.
The margin for profile trimming in this case will sharply decrease due to optimal use a whole bar. However, a transverse profile will be added at the junction of sheets that are 250 centimeters long. The room will be divided strictly in half, and we will only need one joint.
If so, the total number of profiles will be 46 + 5 = 51 meters, which, rounded up, will give us 13 CD profile strips. The cuttings are planned with at least one caveat: the joint of the sheets with the narrow sides will have to fall exactly on the profile lying across the room. In this case, you don’t have to purchase the excess 20 percent.
In the second case, longitudinal profiles are mounted more often. Transverse ones are only above the joints of the sheets.
Please note: the example is quite conditional and is intended to show the calculation methodology. It is usually recommended to place sheets of drywall along the profile. In addition, the step of 0.4 or 0.6 meters is intentionally a multiple of the width of the plasterboard sheet - in this case, the seams will fall exactly in the middle of the plank.
SuspensionsThe step between the hangers when attaching the CD profile is 60 centimeters. If the size of the room is not divisible by 60 centimeters without a remainder, simply divide it by equal plots, as close as possible to the value we need. In this case, there is no need to measure millimeters.
In our second example the simplest way calculate the number of necessary hangers - divide the total length of the transverse profiles, equal to 46 meters, by 0.6. A couple of hangers can be purchased in case of accidental damage, since their cost is low.
Calculating drywall for installation on the ceiling is simple.
A few highlights:
- The standard dimensions of a plasterboard sheet are 2.5 x 1.2 meters. However, some manufacturers produce sheets of both larger and smaller sizes. Accurate information can be found in the price lists.
- When small room(in particular, in our example) you can simply sketch out a sketch and count the exact number of sheets of drywall. When installing sheets along the room, it will take 8 of them, and most of the last pair of sheets will end up in waste.
- If the ceiling has a complex shape or the room is large, take its total area in terms of dimensions (including various protrusions into the room), and add 10-15 percent to it. The resulting value is divided by the area of one sheet (in general case 3 square meters).
Self-tapping screws for drywall are purchased based on a simple calculation - 100 pieces per sheet.
Screws with dowelsTheir total number is also easy to calculate. The UD profile is attached to the wall at intervals of 40 centimeters. For attaching the suspension to reinforced concrete floor One screw with a dowel is enough; in the case of a thick layer of plaster on the ceiling, you can play it safe and use two.
As you can see, calculation of materials for suspended ceiling made of plasterboard is simple and requires only a little spatial imagination. If it is difficult to imagine the arrangement of profiles and sheets in each specific case, drawing a sketch indicating the main dimensions will help (read also). Happy renovation!
Thanks to high technical and operational parameters plasterboard is a universal building material that is used for finishing walls and ceiling surfaces. Drywall is non-toxic and non-conductive electricity, suitable for the implementation of various design ideas. Having experience in carrying out repair and construction work, you can install GC sheets on the ceiling and walls on your own. When planning the finishing of the gypsum board ceiling surface, it is necessary to correctly calculate the amount of material used, calculate the optimal profile consumption per 1 m2, drywall. The ceiling made of gypsum plasterboard is fixed on a supporting frame, it can be “planted” on a wooden or metal carcass.
Drywall classificationGiven the popularity of drywall, the construction market offers a wide range of different kinds of this facing building material from domestic and foreign manufacturers. Professionals prefer products from two large, time-tested manufacturers - KNAUF (Knauf) and GYPROC.
Drywall is a material consisting of three layers, two of which are cardboard, connected by a gypsum mass (core), which has a number of useful characteristics. The core provides protection from moisture and fire. The sheet can be processed polymer compounds, due to which the strength of the structure increases.
Some types of gypsum plasterboard have good flexibility, have soundproofing properties when the frame is properly organized and the seams are sealed with high-quality putty mixtures.
Important! Drywall is classified into categories depending on the place of application and technical characteristics building materials.
According to the place of application, the following types of Knauf plasterboard are distinguished:
To choose the right plasterboard for finishing the ceiling, you need to take into account the classification of the material depending on its functions. This parameter will allow you to determine the technical, performance characteristics building materials, select gypsum boards depending on the functional characteristics of the premises. High-quality Knauf drywall has a special marking indicating its type.
Classification of plasterboard "Knauf":
GKL, GKLV, GKLO are used to create partitions and for cladding wall and ceiling surfaces. GKLV provides additional thermal insulation. Gypsum fiber "Knauf" - perfect solution for basements, attics, rooms where the humidity level exceeds 65%.
Design of a suspended ceiling structure made of gypsum plasterboardFrom a constructive point of view, a suspended ceiling made of gypsum plasterboard includes:
Important! Despite the fact that the cost wooden frame will be cheaper, professional craftsmen To create a reliable, durable structure, it is recommended to use a metal frame.
When planning to install gypsum boards yourself, you must follow the technology, the sequence of work, prepare the necessary equipment, tools, purchase more than one type of profile, hardware (screws, screws, dowels), and reinforcing mesh.
Calculation of materials for HA ceilingsWhen calculating the materials needed for work, it is necessary to take into account the type, type of drywall used, area, functional features premises. As a rule, sheets are produced in standard lengths. The material may differ in width, thickness, weight. The acceptable thickness for suspended ceiling structures made of gypsum plasterboard is 8-9.5 mm.
For correct calculations the required amount of building materials per meter square area, take into account:
- type of drywall;
- type of supporting, supporting structure (frame, profile, hangers);
- materials for finishing cladding.
When performing calculations of civil code per square meter, the dimensions and footage of the premises are taken into account. It is best to make a preliminary plan diagram of the future structure, which will allow you to make correct calculations and find out how many materials will be required to create the structure. Indicate the dimensions of the room and the placement of the profile.
Guide profile quantity
To find out the required number of profiles per square meter, divide the perimeter by the length of the segments. Guides can be purchased three to four meters long.
Important! The number of ceiling profiles is calculated based on the calculation of 3000 mm per square meter of area.
How to calculate connectors, hangers for a profileThe formula will help determine the number of connectors for the profile: K = S*2, where S is the area of the suspended ceiling, K is the number of “crab” connectors. For example, for a room with an area of 6 m2, 12 connectors will be required.
If the area of the room is more than eight square meters, the calculation of the material is carried out according to the formula: K = S * 1.7.
Consumption of hardware for drywallFixing drywall to the supporting profiles is carried out with self-tapping screws, screws, and dowels. The screw is screwed in with a screwdriver or screwdriver. The sheets are fixed to the metal frame perpendicular to the built-in guides. The HA sheet should fit as tightly as possible to the frame. The screw and self-tapping screws are attached in increments of 30-35 cm. To enhance the strength of the structures, the spacing between the screws can be reduced to 15-10 cm. The screw is fixed so that its head is recessed by 1 mm.
Important! Self-tapping screws are placed at least 10-12 mm from the edge of the sheets, and 15 mm from the cut side. Otherwise, cracking of the building material may occur.
When calculating the number of screws, take into account:
- size of gypsum boards, slabs;
- hardware fastening step;
- number of layers of drywall.
If the HA sheets are installed in several layers, the fixation is carried out in different steps. For example: the first layer is attached in increments of 50-60 cm, the second - 35 cm. One sheet will require 65-70 pieces of hardware. In the case of a two-layer structure - 110-115 pcs.
While creating complex shapes drywall is attached to a metal frame of the desired shape, using a pre-prepared template, in which the sides can be made of plasterboard sheets.
Calculation of mass per square meter of partitions from HA This parameter will allow you to calculate how much building material is required, the level of load on the floors created by the structure, which is especially important when arranging attic and attic spaces. Below is a calculation that can be used when standard sizes plasterboard sheets:
The weight increases if a metal frame was used for the structure. If the frame is made of wooden slats, the weight will be less, but the partition should not be higher than four meters.
Material consumption per 1 m2 for suspended ceilingLet us give an approximate calculation of the consumption of building materials for a structure created on a metal frame made of gypsum plasterboard of standard thickness:
- guide profile – 0.8 m;
- rack, ceiling profile – 2.3 m;
- direct suspension – 2-3 pcs;
- reinforcing tape – 1 meter;
- self-tapping screw 9 mm – 4-5 pcs., 25 mm – for a suspended ceiling – 23-26 pcs.;
- dowel, corresponding screw – 5-6 pcs.

Anyone who has ever done a renovation knows how important it is to correctly calculate the amount of materials needed. In fact, these calculations are not so easy, since you need to know all the subtleties and nuances. In the future, we will reveal all the secret formulas for calculation, based on practical knowledge.
Calculating the required materials for the ceiling is quite difficult, because you need to take into account dimensions rooms and sizes of plasterboard sheets and profiles, and you also need to take into account various little things that you don’t even realize right away. Since the calculation process is based on installation technology, you need to start with it.
So, preparatory process installation consists of the following stages:
Frame structure.It is worth noting that it must be made from metal profiles, although a wooden frame will be cheaper. And the wooden frame option is only suitable for a dry room in which there is no temperature difference. To make the correct calculation of the ceiling profile, you first need to decide how we will make the frame.
There are several options:
In order to build a metal frame in the form of a lattice with 600x600mm cells, we need a ceiling profile. This step was not chosen by chance, because a regular gypsum board has a width of 1200 mm, and the sheets are joined to the frame, i.e. The strip of the ceiling profile must pass under the joint.

With this scheme, the ceiling profile is laid along the width of the room every 400 mm, and the transverse one runs only at the joints. You also need to take into account that the entire frame made of the ceiling profile must be attached along the entire perimeter to the wall. This fastening is done using a guide profile, so it also needs to be taken into account when calculating.
Drawing up a sketch.In order to make the correct calculation and take into account all the nuances, it is necessary to make at least a very rough drawing. The drawing is drawn up to scale. It indicates all the overall dimensions of the room and the order of placement of the ceiling profile. The drawing is convenient because it can easily calculate the number of ceiling profile strips needed for installation. And you can immediately figure out how best to position the frame lengthwise or crosswise, what length of profile to buy: 3000mm or 4000mm, and adjust the calculations in accordance with the amount of leftovers.
Sometimes it seems that a profile with a length of 3 meters is more profitable, but after looking at the drawing, you understand that it’s still better to buy 4 meters and use the rest for jumpers. On the sketch you need to mark with crosses where the hangers and the transverse jumpers we need will be attached, so their number is also very easy to calculate by looking at the drawing.
Calculation of the number of guide profiles.
Photo of a guide profile for installing a plasterboard ceiling.
The number of guide profile segments can be easily calculated by dividing the perimeter by the length of the segments. It is worth noting that the guide profile is produced in sections of 3m or 4m. Calculation of the number of ceiling profiles. Ceiling profile must be calculated based on the calculation of 3000mm per 1 m2. But this is a very rough calculation. A more accurate calculation can be easily made based on the drawing. But it is worth noting that before you start counting, you need to choose necessary method installation of the frame, since the number of sections of the ceiling profile depends on this.
Calculation of the number of connectors for mounting a transverse profile.
Photo of a connector for mounting a plasterboard ceiling.
To calculate the number of connectors there is a crab simple formula calculation. First you need to calculate the area of the room. If the area is less than 8.5 m2, then the calculation is made using the formula
where K is the number of connectors, and S is the area of the suspended ceiling. those. if our room has an area of 7 m2, then we need 14 crabs. If the area is more than 8.5 m2, then we calculate the number of connectors using the formula
Calculation of the number of hangers.
Photo of hangers for mounting a plasterboard ceiling.
where P is the number of hangers, and S is the ceiling area.
For example, if our ceiling area is 20 m2, then we need only 14 hangers. 6.
Calculation of the number of screws.
Since we will need screws for various purposes, we will make calculations according to the types of their use.
Self-tapping screws for fastening drywall sheets can be calculated in two ways.
where C is the number of screws, and S is the ceiling area. Or C=L*100, where C is the number of screws, and L is the number of whole sheets of drywall.
Calculation of dowel-nails for fastening hangers.
where D is the number of dowels and nails, and S is the area of the ceiling.
To put it simply, it takes 2 dowel nails to attach one suspension.
Calculation of dowels required for fastening the guide profile. Since the guide profile is attached in increments of 500mm, we calculate the quantity using the formula:
where D is the number of dowels, and P is the perimeter of the room being repaired.
Calculation of the amount of serpyanka tape.
Since serpyanka tape is glued to the joints of drywall sheets, its quantity is calculated using the formula:
where L is the length of the tape, and P is the perimeter of the drywall sheet, and K is the number of whole sheets.
Calculation of the amount of putty.
Photo of putty for installing a plasterboard ceiling.
Since we will need different putty and for different purposes, we will calculate it using different formulas.
Calculation of putty for filling joints is calculated using the formula:
where Shs is the amount of putty in kilograms, S is the ceiling area.
We calculate the putty required for filling drywall sheets using the formula:
where Shg is the amount of putty in kilograms, S is the ceiling area. We hope that these formulas will help you not make mistakes when calculating required quantity material.
For more accurate calculation you can use the program.
