Ceiling wallpaper calculator. Calculation of wallpaper for a room

Please indicate the required dimensions in meters.

Room dimensions:

Y- The length of the first side of the room to be wallpapered.

X- The length of the second side of the room for gluing.

H- Room height.

P- Perimeter (the sum of the lengths of all sides). To calculate the value of the perimeter of the room, you need to add the length of all its walls.

D- Distance from the beginning of gluing to the first corner. Meaning D measured from the beginning of gluing to the first corner (clockwise), it cannot be equal to or greater than the length of the wall.

To carry out the calculation, you can specify either the lengths of the walls of the room or its perimeter (in the second case, the option to start gluing will not be available).

If the room is rectangular or square, enter the parameters Y, X,H... For rooms of irregular shape with protrusions and niches, it is possible to calculate by specifying the values H and P.

Window:

If the room has a window opening, press "Add window" and enter its dimensions: length Wx and height WY.

WZ- The distance from the beginning of the wallpapering determines the location of the window in the room. Enter the distance from the starting point of pasting to the window.

The number of added windows is not limited.

Doors:

In order for the program to take into account the presence of a doorway in the calculation, you must press "Add doors" and enter the values of their length DX and heights DY.

DZ- Distance from the beginning of wallpapering to the door.

It is possible to add multiple doors.

Wallpaper:

L- The length of a roll of wallpaper depends on its type and manufacturer. Standard value L 10.05 m. However, non-woven wallpaper for painting can be produced in rolls of 30 and 50 meters.

W- The roll width is determined by the characteristics of the production line and can be 0.53 m (standard), 0.7 m and 1.06 m.

R- Repetition of a drawing, or so-called. rapport is the distance through which the same pattern is repeated.

Z- Alignment margin, the size of the allowance at the floor and ceiling, which, after gluing, must be cut off with a sharp knife for a ruler or rule (0.05-0.15 m).

F- Move the picture. Check this box if you need to calculate, taking into account the offset of the wallpaper rapport to match.

If you need to print the visualization, check the box " Black and white drawing", So you get a drawing close to the requirements of GOST and save color ink or toner when printing.

Important! If incorrect parameters are entered to continue the calculation, you will be prompted to pay attention to the corresponding parameter and make changes.

The calculator will help you calculate the total area of the walls of the room (in m²), calculate the wallpaper consumption, taking into account windows and doors. You will know the area of one roll of wallpaper, the length of the canvases required for pasting the room of the specified height, taking into account the allowances for trimming, as well as the number of whole canvases of wallpaper contained in the roll. What will be the remainder of each roll and how many rolls (pieces) of a given length are needed for pasting the room. The calculator will calculate how much wallpaper is needed for the room and how many rolls are required, taking into account the presence of window and door openings. The total balance of all wallpapers will also be calculated.

Such data allow you to buy the right amount of wallpaper for the room, taking into account the nuances and glue the room with your own hands or hire professionals. It is advisable to have a stock of one roll in excess of the calculated amount, this will save time and money in the future, in case of incorrect cutting or damage.

It is not necessary to invite builders to glue new wallpapers. Such cosmetic repairs can be done on your own. The main thing is to buy the right amount of material and carefully study the instructions for gluing on the packaging. But how to correctly calculate how much wallpaper is needed for a room? Calculation rules for home renovation.

Measurement matters

The basis of construction calculations is accurate measurements, for which you will need a construction tape. First you need to measure the perimeter of the room being repaired (the length of all walls) without taking into account the width of windows and doors and the level of the walls. And then the length and height of the sections above and below the windowsills, as well as above the doors. Now let's go directly to the calculations.

We display the calculation formula

We divide the resulting perimeter of the room by the width of the selected wallpaper (it can be from 50 centimeters to a meter) and we get the number of solid stripes.
And we divide the length of the roll by the height of the room and we get the number of pieces that can be cut from one package (when placed in 2.5 m, these are four strips).
After that, we divide the total number of solid strips by their same number obtained from one roll. The result of arithmetic will be the number of rolls that are needed to cut only whole strips.
Now it's time to count the number of incomplete segments. The calculation is made according to the same principle, and the result is added to the already existing figure.

In order not to torment the calculator and not bother with unnecessary numbers, you can use a ready-made table (but keep in mind that it, like any online service, carries some error):

Adjustment for products with a pattern

Of course, when wallpaper is chosen for repair that does not require adjustment, everything is more or less simple. But what if the choice fell on a wall covering with a large pattern? In this case, 1 whole strip less will turn out from the pack (due to the need to adjust the pattern). Therefore, the calculation needs to be adjusted.

Calculation example for persistent

There is a room 3 x 4 meters, 2.50 m high; with a doorway, the width of which is 0.8 m, and the height is 2.1 m; and a window, the horizontal of which is 1.2 m, and the vertical is 1.5 m. The selected wallpaper, 60 cm wide, the length of the roll is 10.5 meters.

Perimeter without taking into account the width of windows and openings: 3 + 3 + 4 + 4 - 0.8-1.2 = 12 m

Number of solid cuts: 12: 0.6 = 20 pieces

With a standard room ceiling level (2.5 m), 4 solid strips will be obtained from the packaging (by the way, you need to cut it with a margin, that is, the length of the piece should not be 2.5 meters, but ten centimeters more).

Number of packs for cutting out solid strips: 20: 4 = 5 pieces

With a window size of 0.8x1.5 and doors with a height of 2.1 m, scraps from 5 rolls are enough to paste over the space above the functional openings, but for the space under the windowsill you will have to buy another one (although you can glue the wall under it with a composite piece). This means that a total of 6 single-color rolls or 7 packages with a large pattern are required.

I think it's better to pre-calculate the wallpaper. And then, if the wallpaper is with a pattern, estimate how many rolls you need to purchase additionally. I change the wallpaper every 5 years. As a rule, I take 1 roll in reserve. Change the wallpaper and the mood changes for the better.

Marina N. said:

Personally, I always calculate the number of rolls myself. And I don't trust tables. In the case of plain wallpaper, they are suitable. But if the drawing needs to be selected, then making a mistake is as easy as shelling pears.
And it is always worthwhile to play it safe and take more on the roll. Finding the right wallpaper is easy enough. But the required batch is not. That is, the wallpaper is the same, but the shade is slightly different. And on the wall, this difference is very noticeable.

Iva said:

Better let the wallpaper remain superfluous than there are situations (vacation canceled, work has appeared), when you buy wallpaper and glue them in six months. Then you discover that literally one roll was not enough, but the assortment in stores has already changed. So you find yourself in a situation from which it is very difficult to find a way out.

To make a simple but rather attractive renovation in a standard room, it is enough to use high-quality, inexpensive wallpaper. They will be an excellent means of decorating a room, providing good operational and aesthetic qualities.

Calculating the amount of building materials for decorating a room is as difficult as it is simple. To begin with, the trick is often in uneven walls or ceilings, in the end it turns out not too pleasant when at the end there is not enough calculated material to complete the repair. Therefore, we will try to take into account the maximum of factors in order to achieve the desired result. Let's find out how to calculate wallpaper for a room.

You will learn about:

Measurements

Accurate measurements are an important basis for further actions. A tape measure is required to complete this operation. With its help, we first find out the perimeter of the room, not taking into account the width of the doors and windows, as well as the areas above or below these elements.

Based on these data, it is already possible to calculate the wallpaper for the room. The resulting figure must be divided by the width of the wallpaper to determine the number of canvases. The length of the roll must be divided by the height of the ceilings, which will allow you to calculate the number of canvases in one roll. Now it remains to divide the total number of whole canvases by the number that is obtained from one roll.

As a result, we get the number of whole stripes. To them you need to add more incomplete pieces, which must be taken into account in the calculations. You can count them according to the same principle.

If there is a drawing

We considered the option of calculating, if plain wallpaper is used, and if products with a pattern are used, which requires the combination of canvases, what should be done? The number of wallpapers per room in this case is calculated a little more complicated.

It should be borne in mind that less will be calculated for one sheet in a roll.

Example

Let's give an example of how to calculate how much you need, how many rolls of wallpaper. For example, we have a premise area. 12 sq. m. height 2.5 m. The room has a window (1.2x1.5 m) and a door (0.8x2.1 m). Let's say we chose a material whose roll width is 60 cm, length - 10.5 m.

In this case, the perimeter will be 12 m, minus the width of the window and door. As a result, 20 canvases are needed: 12 / 0.6. With a roll length of 10.5 m, 4 pieces of wallpaper are obtained. As a result, there will be 5: 20/4 whole stripes.

It is also necessary to take into account the areas above the door, as well as above and below the window. There will be enough scraps for this. However, it is recommended to add at least one more roll for an area of 12 sq. m.Consequently, if the wallpaper is monochromatic, you can buy at least 6 rolls, with a pattern - 7.

A room with an area of 18 sq. m. How many rolls are required in this case? Let's try to count according to the old scheme.

So, the perimeter will be 20 m. You will need 34 canvases: 20 / 0.6. And the whole stripes will turn out to be 8.5. That is, you need to buy without drawing 10, with a drawing - 11 rolls. These are the recommendations for rooms with an area of 18 square meters. m.

The selected examples are not accidental, since these dimensions of the premises, 12 sq. m and 18 sq. m. are the most popular. Therefore, for many, the task of how to calculate how much wallpaper is required per room will be greatly simplified.

Summing up

You should not be dismissive of such recommendations, since they allow you to lay a qualitative foundation for further actions, which means that the result will depend on them. The calculation should be made as accurately as possible, this will eliminate the need to buy additional material in the midst of the repair process.

Calculations can be compared to preparing walls for wallpapering. If the procedure is carried out efficiently, the result will delight in attractiveness. It remains to recommend not to rush into calculations. As they say, it is better to measure seven times, but cut off once ...

Door and window openings are not taken into account here, because in any case, you need to buy materials with a small margin. Moreover, when gluing, the craftsmen can spoil several canvases, choosing the best way. Over time, the surface can tear, the walls can be painted by children or spoiled by pets.

All dimensions are indicated in meters (for example, 52 cm = 0.52 m).
If the room has a complex shape (not rectangular), you must independently calculate the perimeter of the walls and specify it manually. In this case, enter the length and width of the room as 0.
A rapport is a step through which the same pattern is repeated. It is usually indicated on the packaging. If pattern fit is not required, specify 0.
How many meters are there in a roll of wallpaper? The standard roll length is 10 m. Some natural species are 5.5 m long, and many fiberglass and vinyl for painting reach 25 m in length.
The most popular web widths are 53 cm, 70 cm and 106 cm.

How the wallpaper calculator works

It is advisable to check all the numbers in practice before purchasing materials. The wallpaper calculator for a room calculates the required number of rolls according to the following algorithm:

calculation of the perimeter of the room;
the estimated height of each canvas, taking into account the margin for trimming and joining the picture;
calculation of the required number of canvases per room;
find out how many whole canvases will come out of 1 roll;
find out how many rolls are required.

Calculation example

The perimeter of a room is equal to the sum of its length and width, multiplied by 2.

P = (5.6 + 3.03) * 2 = 17.26 m.

To find out the estimated height of the canvas, add 5 cm above and below to the ceiling height (total 10 cm), and also, if possible, add the size of the pattern rapport, but in our case it is not.

Design height = 2.5 + 0.1 = 2.6 m.

To find out the total number of canvases, the perimeter of the room is divided by the width of the roll:

17.26 / 1.06 = 16.3 pieces. Round up = 17 pieces.

Now we will find out how many whole canvases will be from each roll, excluding scraps. To do this, its length is divided by the calculated height:

25 / 2.6 = 9.6 pieces. Round the result down (remove the scraps), we get 9 pieces.

Now the final stage remains - the calculation of the number of wallpapers per room in rolls. How many canvases are needed, we know how many canvases will come out of 1 roll, we have also counted, so it remains only to divide the first value by the second:

17/9 = 1.9 pieces. As you can see, for a room with an area of 17 sq. m. with ceilings of 2.5 m, 2 rolls measuring 1.06 * 25 m will be enough.

However, it is always recommended to buy one extra roll for stock, because if at least one canvas deteriorates, you will have to buy additional materials. Even if you find exactly the same type of ornament, it is not a fact that it will be identical, since the colors in different batches may differ. Therefore, in our case, it is not necessary, but it would be better to take 3 rolls, the leftovers will then be useful for repairs.

A lot of preparatory stages precede. This is the choice of a suitable design, and the preparation of the wall, as well as the calculation of the amount of wallpaper per room. In this article, we will analyze all the necessary nuances of such a task.

General Provisions

Let's devote a few words to this choice. Why are they most often used for interior furnishings? The reason for this is that they have many advantages.

Dignity

Huge assortment of all kinds of colors and ornaments, as well as materials used to create products.

Flexible pricing... There are, as well as very cheap models, and incredibly expensive. To a greater extent, this is influenced by the presence of expensive raw materials in the structure.

Do-it-yourself ease of application... Wallpaper gluing does not require any special skills and can be easily implemented independently.

Protecting the surface of the walls and masking their minor flaws.
Ease of drawing up a preliminary estimate... Calculating the number of rolls of wallpaper per room is much easier than, for example, calculating the required displacement of paints and varnishes.

The need for budgeting

There are three most important reasons why you need to calculate rolls of wallpaper per room:

In order not to be without repair work at the very peak. Agree, running while the glue dries headlong in search of an unsupported roll is not very fun. Moreover, a similar shade may be generally problematic to find.
In order not to buy unnecessary products. If we are talking about cheap paper samples, then it's okay, you can type with a margin, in case restoration is necessary. But if it is natural or textile wallpaper, then an extra roll will significantly hit your family budget.

And the last reason is that you simply need to know how much you need to go to the store.

We count

You will need the following things to carry out the calculations:

Required tools

Roulette for taking the necessary measurements;

Pencil and blank paper for taking notes;

Calculator to quickly deal with calculations.

We carry out measurements

The calculation of wallpaper consumption per room will not be correct without precise linear dimensions:

The first is to measure the perimeter of the room. Let it be 18 meters in our case.

Then the height of the ceilings. Usually it is two and a half meters. If you use products with a pattern, then you need to add an additional thirty centimeters to fit it.

Tip: it is also recommended to immediately take into account some margin, compensating for the unevenness of the walls, and add another five centimeters. Since it is much easier to cut off the protruding edge than trying to patch up the translucent wall with segments.

You will also need the parameters of doors and windows. After all, they do not need to be glued, so why buy extra material? For example, let's say that the result is eight square meters.

The width of the classic wallpaper is 53 centimeters, and the length is 10 meters and 5 centimeters.

Advice: if you plan to use wallpaper for painting, then pay attention to the labeling of the rolls. Since they usually differ significantly in size from standard products, this must be taken into account in the calculations.

Formula

Instructions:

We multiply the perimeter (P) by the height (H), taking into account the required margin: 18 × 2.85 = 51.3 m 2. This is the total area of the walls (S o).
But in the room there are door and window openings (S p), which we measured in advance, therefore 51.3-8 = 43.3 m 2, which will be the final area (S and).
We find out the surface of the roll by multiplying its length (h 1) by the width (h 2) 10.05 × 0.53 = 5.33 m 2 (S p).
We divide the required coverage area by the area of one roll and we get: 48.3 / 5.33 = 9 units of rolls are necessary for the complete decoration of the room in question.

A single formula for calculating wallpaper for a room will look like this: (P × h-S p) / (h 1 × h 2). You just have to substitute the data that you will receive after the product of all the required dimensions: P is the perimeter of the room, H is the height of the ceilings adjusted for cropping, S p is the area of all openings in the room, h 1 is the length of one roll and h 2 is its width.
