Calculate wallpaper online on the wall. How to calculate the wallpaper for the room: the right repair without extra costs. Prices for various types of liquid wallpaper

Repair in an apartment is a difficult period for every home master, but this can be easily fixed with a little preparation. Since most often they try to re-glue wall coverings, in this article we will deal with their calculation and find out, for example, how much wallpaper is needed for a room of 15 meters around the perimeter so as not to spend extra money. In addition, you need to immediately determine their type, then the next interior update will not occur before 5 years.

The existing variety of models and sizes of wallpaper should not unbalance you.

Let them differ in length, width and other characteristics, it will even benefit us, as it will allow us to make the right choice more carefully and optimally:

1. We will start by calculating the number of rolls.
2. Then we learn the universal formula for determining the amount of material.
3. Then the professionals will tell us about some secrets.
4. Let's finish the main block of the article with the rules for choosing these wall coverings.

Calculate wallpaper rolls

We will have to use school knowledge of mathematics, which will help not to get confused in the numbers, but first determine the main parameters:

1. Perimeter selected for. To do this, you need to add the lengths of all the walls and divide the resulting figure by 0.53 m or 1.06 m. You should also proceed when using a non-standard width of the finishing material. This will allow us to find out the number of lanes.

1. Roll width and length. The standard width is 53 cm and 106 cm, the rest are non-standard. Moreover, the length in the first case can be 10.05, 12 or 15 m, in the second - up to 25 m. If you have ceilings in the apartment of 2.4-2.5 m, then the narrow one is enough for 4 lanes.

For a better understanding, let's give an example of how to find out how much wallpaper you need per room, where:

• the total length of the walls will be - 5 and 6 m;
• ceilings - 2.5 m high.

Calculation:

1. Width 53 cm:

5*2+6*2=22 m (total perimeter of the room);

22:0.53≈42 (bands);

42:4≈11 (rule).

Answer: for a room with sides of 5 and 6 m and a ceiling height of 2.5, you will have to buy 11 rolls.

1. Width 106 cm:

22:1.06≈21 (bar);

Since there will be 10 strips in a roll 25 m long, it means that in our case we need 2 rolls. The last strip will have to be joined at the bottom so as not to buy a new one.

In fact, this calculation will be somewhat approximate. So, knowing the basic parameters, how much wallpaper you need for a room of 12 meters along the perimeter is already easy to determine, namely: 12: 0.53: 4≈ 6 pieces.

General calculation formula

From the above, you can easily draw up a general formula for these actions: P: L: 3 (with image fitting) or 4 (without image fitting), where P is the perimeter of the room, L is the width of the wallpaper roll.

Tip: The result should always be rounded up.

Now it's time to talk about the space under the window and above the doorway, since in these areas you have to use not a whole strip of wallpaper. One option is to use the leftovers from fitting the pattern. Thus, you can save a lot on repair work.

Tip: to determine how much wallpaper you need for a room of 20 meters in area with a wall length of 5 and 4 m, you need: (5 * 2 + 4 * 2): 1.06: 10≈1 (roll).

If you are a fan of exact numbers, do the following:

• determine the number of rolls using the formula, not taking into account the space above the door and under the window;
• add to them the required amount for these areas.

In this case, the result will be as complete as possible.

Let's determine how much wallpaper you need for a room of 16 meters and 17 meters with a pattern fit:

• 16:0.53:3=10 rolls;
• 17:0.53:3=11 rolls

Below will be offered an instruction for counting the number of wallpapers for economical home craftsmen:

1. If a repeating pattern is implied on wall coverings, check with the seller for the size of his step and divide the height parameter by this figure.
2. Round the resulting number and multiply it by the same image step size. The figure found as a result will be the length of the strip that needs to be cut from the canvas.
3. Calculate the difference that will go to waste by subtracting the height of the wall from the length of the wallpaper strip.
4. Divide the total length of the roll by the length of the strip you found in step 2 to get a factor. Multiply the difference found in point 3 by it. Get the total amount of waste and subtract it from the total length.

Now divide the value of the pasted area by the waste-free number from point 4. This result of the number of rolls will be the final one.

How to choose the type of wallpaper

In addition to the quantity, the selection of the canvas from the appropriate material will also be important. You must understand that not all materials can be universal, so what you can stick with your own hands in the kitchen is unlikely to be a good option in the children's room.

Manufacturers today offer a wide range of wall coverings of this type, the price of which differs from each other, including paper, non-woven, vinyl, fabric, bamboo, velor:

• when choosing wallpapers for wet rooms, for example, a bathroom, kitchen or corridor, it is better to give preference to washable coatings. In addition, they must be as resistant to mechanical stress as possible;
• for, a hall or a children's room, it is better to buy natural coatings (bamboo or paper);
• velor and fabric options are well suited for a decorative effect. However, in operation they are not very profitable.

Conclusion

From the article, you learned how easy it is to calculate, for example, how much wallpaper you need for a room of 14 meters around the perimeter. At the same time, they also realized that repair work should not be ruinous for the family budget.

Therefore, before starting them, it is necessary to carry out preliminary calculations so as not to buy unnecessary, in particular, wallpaper. They can be of different widths and lengths, which should also be considered. The video in this article will help you find additional materials on this topic.

Despite the fact that the range of materials for the repair and decoration of houses and apartments is replenished almost every year with one or another novelty, wallpaper does not lose its “leadership position” and still remains, probably, the most popular way to decorate walls in residential premises. Moreover, the widest variety of modern wallpapers, made using the most advanced technologies, allows you to complete the decoration in any interior style, authentically imitate wall cladding with many natural materials. And if we add here the relatively low cost and the possibility of independent finishing work, then the popularity of wallpaper gets a completely logical explanation.

Before the owners of housing, who have decided in favor of such a finish, the question will surely arise - how to calculate how much wallpaper is needed per room? We will try to help them with this - below is a convenient online calculator.

For those readers who have already been pasting wallpapers and, therefore, “savvy” theoretically, there should not be any problems using the program. Beginners may have unclear questions - some explanations on the use of the calculator and on the basic principles of calculation are given below.

Wallpapering is not a difficult task for an experienced craftsman. And from personal experience I can say that the main problem that I had to face most often was the lack of a strip or a whole roll. The customer did not count correctly, and you have to buy more and waste time. To minimize all risks and simplify the calculation process, it is recommended to use the wallpaper calculator below. Its use should not cause difficulties. And if something is not clear, read the detailed instructions and read the calculation example.

How to use the wallpaper calculator

In order to correctly calculate the number of wallpapers for a particular room, you must enter the correct initial data. Let's look at each item:

1. Room width.
2. Room length.
3. room perimeter. This parameter is automatically calculated based on the length and width. It is needed to determine the total area of ​​​​all walls, taking into account their height.
4. Ceiling height - the distance from the floor to the ceiling.
5. The number of doors in the room. If there are no doors, items 5, 6, 7 are not set.
6. Door height. If there are several doors and they have different sizes, indicate the smallest height.
7. Door width. If there are several doors and they have different sizes, indicate the smallest width.
8. The number of windows in the room. If there are no windows, items 8, 9, 10 are not set.
9. Window height. If there are several windows and they have different sizes, specify the smallest height.
10. Window width. If there are several windows and they have different sizes, specify the smallest width.
11. Roll length. The standard size is 10.05 m. There are also 25 meter non-woven vinyl wallpapers. Carefully study the packaging - this parameter is indicated there.
12. Wallpaper width. Standard sizes are 53 cm and 106 cm. They are also indicated on the roll packaging.
13. Rapport of the picture - the height of the picture ( →I←). That is, if the rapport is 46 (cm), then cutting off a strip of 2.5 meters (250 cm) in size from a roll, it will contain 5 sections of 46 cm each and one incomplete - 20 cm. Therefore, in order for the next strip to coincide with previous, it is necessary to cut off an extra section of 26 cm (46 - 20).
14. Shifted pattern - stepped docking (diagonal docking) of the pattern. This information is indicated on the packaging. For example, the designation 46 ⁄ 23 means that 43 is the rapport, and 23 is the distance in centimeters that each next sheet should move. By marking this item in the calculation, the maximum possible shift in the rapport floor will be set.
15. Leveling margin is the distance needed to fit and cut comfortably.

If the label contains the following symbol 0I←(or →I0), then such wallpapers are glued without selecting a pattern, and item 13 in the calculator can be omitted. Also, if step docking is not indicated, then item 14 is not set.

Table with wallpaper marking according to the method of selection (fitting) of the pattern:

An example of calculating wallpaper using a calculator

First of all, we will carry out the calculation without using an online calculator, and then compare the results.

Initial data:

• The length of the room is 4 m.
• The width of the room is 3.2 m.
• Ceiling height - 2.65 m.
• One door - 85 cm × 205 cm.
• One window - 135 cm × 135 cm.
• Wallpaper - 10.05 m (length) and 53 cm (width).
• Rapport - 64 cm.
• The drawing is straight, horizontal joining.

Next, glue the wall with the window. The window is in the center, and from the corner to the window 0.925 m - or almost 2 wallpaper strips (106 cm). Pieces go along the top and bottom of the window for 106 cm - we do not take them into account yet. 108 cm remains to the corner, or 2.02 stripes.

Consider a wall with a door. Since the width of the door is not significant, it can not even be taken into account. We get 7.54 stripes(remainder 0.46 bands) (4 ⁄ 0,53).

To summarize:

1. 13.58 round up to 14 stripes.
2. 2 stripes.
3. 7.54 round up to 8 stripes.
4. Total 24 strips or 8 tubes(3 strips come out of one tube).
5. There are areas above and below the window - 2 strips 80 cm long and two strips 45 cm long. Taking into account the rapport of 64 cm and the leveling margin, the remains of 8 tubes may not cover the required areas. Therefore, an additional tube is required.
6. The end result is 9 tubes.
7. The result calculated by the calculator also gives 9 tubes.

As you can see, the presented online wallpaper calculation calculator fully copes with the task. It is an indispensable tool and saves you time.

Wallpapering walls is a quick and relatively cheap way to decorate rooms. Before heading to the hardware store, decide how much material you need for the room. To do this, you need to know how to calculate the wallpaper so that there is enough for everything and there is no surplus left.

In this article, we will consider how best to make calculations, what measurements need to be taken, what to look for when planning a purchase.

Calculation of wallpaper for a room: formula and instructions

Along the perimeter of the walls, it is easy to calculate the wallpaper for the room. The formula is as simple as possible. Use a tape measure to measure the length of two walls, add up the resulting numbers and multiply the result by 2.

For example: the length of one wall is 4 m, the other is 6 m. Thus, the perimeter is: (4 + 6) * 2 \u003d 20 m. Then the height of the ceiling is found. Let's say it is 2.5m. With this height, one roll can be divided into four equal strips, since the standard length of a roll is 10 m, and its width is 53 cm.

The total width of the four stripes is calculated by multiplying their number by the width of one strip: 4 * 53 = 212 cm. Then the perimeter is divided by 212, it turns out: 2000/212 = 9.43, the sum is rounded up to an even count and the number 10 is obtained. Thus, for a room with a perimeter of 20 m you will need 10 rolls of wallpaper. From the table below, you can find out how many rolls are required for a room with different ceiling heights and different perimeters.

How to calculate the number of wallpaper with a pattern

In order for fragments of a large pattern to match on adjacent panels, they are shifted in a certain way. A sales assistant cannot always advise on how to calculate the number of wallpapers with large patterns. Therefore, when buying them, 2 additional rolls are added to the required number of rolls.

Rapport (location of sheets relative to each other and their number on one wall) is indicated on the package. The larger it is, the more waste remains when gluing combined panels. Therefore, for large-sized premises, it is advisable to buy more additional rolls. To save on the remaining waste, you can paste over inconspicuous places: under the battery, behind the doors, etc.

Calculation of wallpaper for painting

The standard size of wallpaper for painting is the same as for ordinary ones - 10 m by 53 cm. There are other size options: 17 m by 53 cm, 33.5 m by 53 cm and others. Below is a table to calculate them:

Calculation of non-woven wallpaper

The width of the rolls of non-woven wallpaper is 100 cm. We must not forget this when dividing the perimeter of the room by the width of the panels. These wallpapers are calculated according to the same principle as ordinary ones, using the perimeter and height of the walls.

Additional ledges or corners in the room increase material consumption. When pasting the corners, an overlap is made, and then the wallpaper is cut so that the pattern on adjacent strips docks evenly. In such cases, 1-2 additional rolls are required.

Calculation of wallpaper by room area

Another calculation method is the calculation of wallpaper according to the area of ​​​​the room. To find the perimeter, we use the already known indicators of length, width, height - 4.6 and 2.5 m. We find the area of ​​​​one wall: (6 + 4) x 2.5 \u003d 25. We multiply the resulting amount by 2, since there are identical walls in the room 2, and get 50 square meters.

Then we calculate the area of ​​one roll. To do this, we multiply 0.53 by 10, the product of these numbers is 5.3 sq.m and there is the total area of ​​​​the roll, it can be pasted over 5 sq.m of the room.

Wallpaper for walls with a border is calculated by the area of ​​\u200b\u200bthe walls or along the perimeter

Modern designers have invented a finishing method in which not only the wall is pasted over with wallpaper, but also a border or decorative plinth. On sale there are special wallpapers, the pattern of which is suitable for such pasting. It is applied in such a way that its elements falling on the curb fit perfectly with the elements on the wall.

Manufacturers create compositions that allow you to combine wallpaper in contrasting colors and various patterns at the bottom and top of the wall. And the border will serve as a divider for the drawings.

Usually rooms with borders are faced from the ratio: 1 part to the bottom, 2 parts to the top. The number of wallpapers with such a lining is also calculated based on the perimeter.

With a ceiling height of 2.68, the length of the lower panel is 100 cm, the upper one will have to be 168 cm. From one 10-meter roll, either 10 lower parts or 5 upper ones will be obtained. Those. the length of one roll is divided by the length of each part.

If you have difficulty calculating the perimeter, you can use the following algorithm. Add the length and width, multiply the result by 2 and subtract the width of the door and window openings from the product. For example, the width of the room is 6 m, the length is 4 m. The standard width of the door is 0.9 m, the windows are 1.5 m. Mathematically, it looks like this: (6 + 4) * 2 - (0.9 + 1.5) \u003d 17.6 m, which is the total perimeter of the room.

To calculate the lower part, we divide the roll into 10 strips 53 cm wide. 53/10 = 5.3 - the area that requires 1 roll of wallpaper. Then, we divide the perimeter by this figure: 17.6 / 5.3 \u003d 3.3. Thus, for facing the lower part of the room, 3-3.5 rolls will be required.

The upper part is calculated according to the same principle. It is known that 5 upper panels are obtained from 1 roll. One roll can cover 2.6 meters of wall. Perimeter - 17.6 divided by 2.6. As a result, 7 rolls are enough for the upper part of the room.

There is another way in which we calculate the number of wallpapers by the area of ​​\u200b\u200bthe walls. To do this, we conditionally take the upper and lower parts of one wall for different walls. The area of ​​each of them is found by a well-known formula. Then we add the two resulting products and multiply by 4, according to the number of walls in the room.

Calculations for combined cladding

Not always cladding is limited to just wallpapering. Modern designers offer combined solutions for wall decoration. Either different types of materials, or wallpapers of different textures and colors can be used.

The material for such repairs is calculated individually for each case. For example, you are going to highlight with a bright insert some fragment of a wall, 3 m wide. With a ceiling height of 2.5 m, 6 panels or 1.5 rolls of wallpaper will be spent on this insert. Non-woven wallpaper for this will need 1 roll, since its width is 100 cm.

Wallpaper is a convenient and practical way of interior wall decoration, which has not lost its popularity over the years. In addition, if you need to update the repair without much cost and effort, you just need to stick another wallpaper.

The choice of materials and colors is large enough so that everyone can choose a pattern to their liking. When choosing wallpaper, one should not forget not only about the calculation of the required number, but also about the correct selection of consumables (glue, brushes).

You may have some wallpaper left, and then in case of minor damage to the surface, you can glue it, hiding the defects.

If you doubt that you can stick the wallpaper yourself, seek help from specialists.

In order to paste new wallpaper, it is not necessary to invite builders. Such cosmetic repairs can be done on their own. The main thing is to buy the right amount of material and carefully study the instructions for gluing on the package. But how to correctly calculate how much wallpaper you need per room? Calculation rules for home repairs.

Measurement matters

The basis of construction calculations is accurate measurements, for which you will need a construction tape measure. 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 window sills, as well as above the doors. Now let's move on to the calculations.

We derive the calculation formula

• The resulting perimeter of the room is divided by the width of the selected wallpaper (it can be from 50 centimeters to a meter) and we get the number of solid strips.
• And we divide the length of the roll by the height of the room and get the number of pieces that can be cut from one package (when placed at 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 the arithmetic will be the number of rolls that are needed to cut only whole strips.
• Now it's the turn to count the number of incomplete segments. We calculate according to the same principle, and add the result to the already existing figure.

In order not to torment the calculator and not to fill your head with extra numbers, you can use a ready-made table (but it is worth considering that, like any online service, it carries some error):

Adjustment for products with a pattern

Of course, when wallpaper is chosen for repairs that do 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, you will get 1 whole strip less from the pack (due to the need to adjust the pattern). Therefore, the calculation needs to be corrected.

Calculation example for persistent

There is a room 3 x 4 meters, height 2.50 m; 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. Wallpaper is selected, 60 cm wide, the roll length of which 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 whole strips will come out of the package (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 packages for cutting out solid strips: 20:4 = 5 pieces

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

Faith said:

I think it's still better to pre-calculate the wallpaper. And then, if the wallpaper is with a pattern, figure out how many rolls you need to purchase additionally. I change 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 you need to select a drawing, then making a mistake is as easy as shelling pears.
And you should always play it safe and take more on a roll. Finding the wallpaper you want is easy. But the necessary party - no. That is, the wallpaper is the same, but the shade is slightly different. And on the wall, this difference is very noticeable.

Iva said:

Let the wallpaper remain superfluous, than there are situations (vacation canceled, a job appeared) when you buy wallpaper and glue it after 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.
