How to calculate the number of wallpaper. How to calculate the desired number of wallpaper? How to measure non-standard surfaces

The process of sticking wallpaper is not as simple as it seems at first glance. To better and beautifully glue the room with rolled wallpaper, it is necessary to produce the right measurements. On their basis, it is easier to produce accurate calculations of the required number of wall cloth.

Required values

In order for the sticking process to go smoothly and without the "extra nerves", as has already been said earlier, everything must be measured in advance and calculate. Otherwise, there may be a "surprise" in the form of a bare spot on the wall with the missing piece of wallpaper or, on the contrary, there will be too many rolls.

First of all, for calculations, you will need such values \u200b\u200bas the length and the height of each of the resulting walls in the further populated wall.

For example, you can take the usual room of standard sizes, for example, it has the following metra: the height of the walls is 2.5 m, the width of the room is 3 m, the length is 5 m.

The first thing to do is, armed with the usual roulette, find out the length of each of the walls. Then we add well-known values \u200b\u200bon paper: (3 + 5) x2 \u003d 16 m is the perimeter of the measured room.

Next, you need to measure the width of the wallpaper (usually, these parameters are written on each roll, the standard width is 0.5 m). The resulting number of the perimeter of the room is divided to the width of the wallpaper canvase, that is, 16 m: 0.5 m \u003d 32. This number shows how many wallpaper bands will need for the room.

The next value that is needed when calculating is - how many bands will work out from each roll so that in the future it is possible to find out their quantity. The standard roll has a metrar of 10, 25 or 50 meters, but if a non-standard is purchased, where fractional values, then for ease of calculation, is rounded to an even number. This length is divided at the famous height of the room wall. It turns out 10 m: 2.5 m \u003d 4 - so many bands will turn out from one roll of the wallpaper.

It remains for small - find out the exact number of rolls. To do this, you need to divide the number of necessary strips for the entire room on the number of bands in one roll. 32: 4 \u003d 8 - so much will need rolls for the complete salary of the selected room.

Masters, in turn, advise still to purchase on one wallpaper roll more, as there is always a possibility to make a mistake or accidentally spoil a few bands, and not to run for the next convolution of the desired wallpaper ... which may not be in the store) , it is better to always have a little about the reserve. It will always be possible to replace the damaged fragment by children or pets.

Preparation of instruments

A very important process before the direct salary of walls with wallpaper is thorough preparation, since in the course of this process, a certain number of auxiliary tools and remedies will be required.

The very first thing, without which it is not to do is an ordinary pencil, they will need to notice the postponed length on the wallpaper canvase. It can be both special construction and ordinary.

Of course, do not do without a long line or construction roulette. With their help, the parameters of the room will be measured (length, height, width), as well as to produce a wall-mounted roll. It will be difficult to do the measurements of the room space and for a long time, so it is better to use roulette for these purposes, and with its help, in turn, it is hard to carry straight lines on a sheet of wallpaper. In this regard, take better and more.

To cut the canvas to separate sheets, the stationery knife or sharp scissors use, but the wizard advise the first option, since it is easy to make cuts or slotes for outlets and wiring. They also make it easy to make injections when you need to release air bubbles, but it is more intelligent to use the needle here, it will be more neat and unnoticed. In turn, the scissors will be suitable for cutting out some "figured" parts, where the clarity is required and the smoothness of the lines.

Of course, a screwdriver will be required to remove the protective discovered box from the switches or any other mounts on the wall.

Since the walls and corners in the house are not always perfectly smooth, and the drawing is present on the wallpaper, the construction level is useful. With it, it will be easy to glue the strip to the drawing, and the angles are not "scruleting."

You will need two containers, one for water, and the second will get into the second. Water is needed that a rag wipe the randomly fallen drops of glue is not there, if you wipe it quickly, then the traces will not remain.

If we talk about a rag, it must necessarily be clean and soft (wet wallpaper is easy to minimize and damage). It is very important that in the process of wiping excess glue, it was wet, but not wet, otherwise the wallpaper may be soaked in moisture and just get along the wall.

In order to mix the adhesive solution to qualitatively, the building mixer is needed or an ordinary wooden stick, which will have to change the ingredients for a long time and high quality. The masters advise pouring the glue not all immediately, and parts, so it will turn it out more homogeneous and without lumps.

In order for the glue to be uniformly and quickly, it is best to use a roller or a wide brush with an average rigidity. As for the roller, he must have a small pile.

A very convenient adaptation for sticking is a painting bath. She has a deepening for solutions and a ribbed surface with a bevel (so that the surplus merged back). It is good to pour the glue into it with small amounts, dipping a roller there, and the surplus is removed by scrolling it on the ribbed side. It is very important that its size corresponds to the width of the roller, otherwise there will be no sense from the bath.

A good assistant in getting rid of the air intake under the glued wobbly canvas will be a lobby spatula. The main thing is that it is either rubberized or plastic, otherwise the metal can smit or break another wet, not dried strip. He "cattures" not only air bubbles, but also an excess of glue that needs to be immediately woozy and clean.

For such places like joints between stripes, there is a special roller. It is made of rubber or silicone and has a shape of a small round barrel. They are very convenient to urge the joints, without damaging or deformation with wallpaper. There is also a special roller and for corner contacts of the surface with a wallpaper blade - these are places at the ceiling, near the floor or in the corners of the room. Thanks to its flat form, they are easy to sell all the corners to keep the strip well.

Of course, you should not forget about the isolent. With it, it is necessary to attach all the "naked" wires, which will continue to serve to set the outlet and so on.

Of course, the above mentioned list can be supplemented with all sorts of newcomers, but for high-quality shocking of the wallpaper canvas is enough.

Measuring area of \u200b\u200bthe room

As mentioned earlier, without accurate measurement of all three main parameters of the room, it will not be possible to calculate the exact number of wall rolls. This is especially true of the case when it is necessary to attach not one room in an apartment or house, but a few.

To make it easier to visualize, you will need to draw a general schematic plan of the room. To do this, you will need a pencil, a ruler and a simple sheet of paper. You will also need a roulette with which spaces will be measured.

Schematically, designating the walls of the walls and the location of the windows, it is necessary to sign such values \u200b\u200bas the height of the walls, width and length of the room itself. Then specify the windows parameters to subtract them from the total element, as they do not need to be accumulated.

Next, we learn the area of \u200b\u200beach wall and fold among themselves to find out the total number. To do this, we multiply the height of the width. Suppose that this space has a height of 2.5 m, the width is 3 m, and the length is 4 m.

We learn the area of \u200b\u200bthe first wall: 2.5x3 \u003d 7.5 square meters. M. Next, multiply this number 2, as two such walls are the opposite. 7.5 square meters m x 2 \u003d 15 square meters. M - in the amount of 2 walls. We do the same with two others. (2.5 m x 4) x 2 \u003d 20 square meters. m. We fold the obtained values \u200b\u200b- 10 +15 \u003d 25 kV. M - the area of \u200b\u200bthe entire surface of the walls in the room.

Do not forget about the surface area of \u200b\u200bthe window that you need to deduct. At first it must be calculated by the already known method. Take the size of the usual window - the width is 1.35 m, the height is 1.45 m. 1.35 x 1,45 \u003d 1.96 square meters. m. The result obtained by subtract from the total area of \u200b\u200bthe wall surface of the room - 25 -1.96 \u003d 23.04 square meters. M - the area of \u200b\u200bthe covered surface of the walls.

In any room there is an entrance door or passage, which is also not a surface, it does not need to shook with wallpaper. In this regard, the surface area of \u200b\u200bthe door and the input space itself must be subtracted from the above total wall area. The usual door with the fraumuga has a height of 2.5 meters, and the width is 0.8 m. 2.5 x 0.8 \u003d 2 kV. m (door area with an interval from it to ceiling).

We subtract the calculated area of \u200b\u200bthe total - 23.04 - 2 \u003d 21.04 square meters. m.

From the resulting result, using simple mathematical calculations, you can find out the number of required wallpaper rolls, knowing the area of \u200b\u200bcoating one roll.

It also multiplies the length of the width, and then the total area of \u200b\u200bthe room is to share on the area of \u200b\u200bone wallpaper roll.

Non-standard surfaces

There are such rooms that have a non-standard layout, and the calculation must still be implemented. To be accurate by 100%, then the room of standard sizes and parameters, the walls are not always smooth and you will first need to align, otherwise the ornament or drawing on the wallpaper will be hard to docile throughout the surface of the walls.

Unusual surfaces include walls with rounding in the corners, or when the wall itself has the form of the semicircle. There are plasters where the walls are spinning to the ceiling and have a dome-up part. There are also protrusions or partitions that share space on zones and so on.

To determine the number of rolls of the wallpaper canvas, calculate the area will still have to and in this case. Masters advise "cut" space on comfortable figures (square, rectangle). For this, the width of the wall and its height at the highest point and mentally connected to the rectangle. The corners will remain rounded triangles, which are also broken into squares. Later, all the amounts of the squares are folded, and the total area is obtained.

But many "experienced" covers say that it is not necessary to calculate so thoroughly.

In the process of sticking, it is necessary to simply cut the excess along the bend contour using a conventional knife or the stationery (it turns out to be careful).

If the wall has the parameters of a conventional rectangle, but convex shape in the form of a Russian letter C, then its width is measured using a roulette that you need to close to the surface. The height will be ordinary, without any problems and any changes. And then the area is calculated according to the well-known formula.

In the case when there are convex details or certain designs on the wall (for example, a pipe from the exhaust, which was closed with rectangular sheets of drywall or PVC), then its area also needs to be calculated and added to the total surface. Well, when it has a clear angular shape, by type of a square or rectangle, but if there are rounded parts, they are also better to calculate, like the "right" figures, and then remove the small excess the knife.

Roll sizes

After all the necessary room parameters are calculated, then you should proceed to the calculation of the wallpaper canvase. Before this you need to find out the width and length of the chosen roll.

To date, there are several standards on the metric parameters of the wallpaper canvas, as manufacturers are both foreign and local, that is, Russian.

The width of the roll has many variations, but today there are three major sizes that most manufacturers are trying to adhere to:

• 53 cm - The most frequently used size, so it is found in overseas and local wallpaper brands. Since it is very convenient for sticking, it prefers more than the rest.

• 70 cm- The second in the frequency width. This size is more popular with European manufacturers. As everyone knows, people try to acquire imported wallpapers, because they, in turn, are better in some parameters, therefore, the demand for such a width is very high.
• 106 cm - As the masters say, the wider wallpaper, the faster it is possible to finish the process, but it does not always happen. With such a width most often produced "massive" wallpaper rolls.

For the Russian market, meter and half-meter wallpapers are preferred in width.

As for such a parameter, like the length, everything is easier here.

In this case, there are also three main sizes:

• The most basic length is 10.5 meters. She sticks to most of the wallpaper manufacturers. It is enough for 3 full-fledged stripes on the wall.
• For width rolls, 53 centimeters wide is characterized by 15 meters long. As a rule, it is wallpapers made of vinyl or phlizelin.
• For heavy wallpaper canvas with a meter width made of fiberglass or the same phlizelin, a meter is 25 meters.

The wallpaper roll, there is a concept as a coating area, which varies from its length.

When the standard length is 1050 cm, and the width is 53 cm, then according to the formula (S \u003d A * B), it turns out 53000 sq. cm (5.3 sq. M). With a similar width, and a length of 1500 cm, the area will be equal to almost 80,000 square meters. cm (8 square meters). If you take a length of 2500 cm, and the width is 106 cm, then it turns out - 25 square meters. m. - 25000 square meters. cm.

Rapping and drawing parameters

It may seem that the shot of wallpaper is reduced only to just calculate the metrar, the number of strips, and then rolls. Basically, it is, but only concerns wallpapers that do not have a drawing or a complex ornament. In this case, it will take a fitting of the wallpaper canvas so that it looks in a monolithic piece.

Before choosing a wallpaper with a pattern, it is necessary to determine what is rapport. The rapport is called the repeating pattern or pattern on the wallpaper roll. In turn, it is divided into 2 types. It happens the side (the picture goes on the width of the sheet) and the altitude (the ornament is repeated in height). This location directly depends on the parameters of the canvas and size and the type of ornament itself.

When sticking such wallpapers there is one main need - to level the wallpaper strips in the figure, which affects the final result. The fact is that for such wallpapers there is a slightly different calculation of rolls.

To do everything correctly, there will be conditional designations located on each such wall-mounted canvas:

• If the label is drawn the designation - the arrow along with 0, then this suggests that this roll of wallpaper can be glued and docked with stripes, without fearing to disturb the integrity of the ornament, there is no special difference.

• When the arrows pointing to each other are depicted, then the wallpapers must be clearly knocked around the edges. But if the specifying arrows are offset (one above another), it is necessary to glue with up or down (in this case, a special calculation of the canvas will be made along the entire surface of the wall). As a rule, digits are indicated on the packaging of such rolled cloths. For example - 55 \\ 23, the first digit indicates (in centimeters) the size of the ornament or pattern, and the second one - how much (also in centimeters) should be shifted to one lane relative to the other.
• In the case when the arrows indicate each other from the bottom up, then this means that during the location of the wallpaper clamps, a counter dock should go.

Do not throw short stripes with a pattern.

They can be used for space under the window, between the battery and the windowsill, or for the walls of the wall above the door.

From the above, it is clear that the counting of material with a rapport will be different. To begin with, you need to know the perimeter of the wall, then divide it on the width of the wallpaper and get the number of necessary bands. Then, you need to count how many displacements will need to be done on one lane, the greater the drawing, the more wallpaper will need. Knowing this information, we find the number of rolls.

With the help of roulette, we measure the length of each wall and fold the results obtained:

3 + 4 + 3 + 4 \u003d 14 m, or (3 + 4) * 2 \u003d 14 m.
We learned the perimeter of this room. It is equal to 14 m.

Dividing the perimeter of the room on the width of wallpaper, we get the number of lanes of wallpaper , necessary for the adhesive of this room:
14/05 \u003d 28 bands.
Now we consider how many bands will work out from one roll. For this, the length of the roll is divided to the height of the wall.
10 / 2,5 = 4

The resulting number is always rounded in a smaller side to the whole. Next, the number of LOS required should be divided into the number of bands that can be obtained from one roll:
28/4 \u003d 7 rolls.

It is advisable to purchase more than one roll than required. In the event that any plot will be equipcan or damaged, you will always have the opportunity to use an additional roll.

Preparation of walls under the wallpaper

For the preparation of walls under the wallpaper, it is necessary to carefully quit indoors. The litter is completely changing on the floor - old removed.

From the tools for marking the surface of the wall and wallpaper is best suited pencil The average hardness (TM or ST) is neither a ballpoint pen nor the marker fit, as the traces of them can then manifest themselves on the wallpaper.
For the lines you need a line of length 50 cm And plumb, but it is only better to use the level.

For cutting Wallpaper (and cutting edges) need scissors (long) and wallpaper knife.
To apply adhesive composition on the wall and wallpaper will need brushes and rollers.

In addition, it will take a container for the preparation of glue and water to rinse the sponge. For the roller, the tray will be required, as you get the glue on the roller from the bucket is extremely uncomfortable. And also need a stepladder when sticking wallpaper.
Working with glue - the work is dirty, so take care of overalls. Bathrobe, apron, brazing on the head, old sneakers or sorting sneakers, rag in a pocket for wiping hands ...

If you do not have a large sliding table, on which you can post a cloth wallpaper full length, then you will have to work on the floor. And work on the floor requires more
Careful insulation of the floor After all, the hitting of glue on the floor covering on the floor is inevitable.

Before the start of cutting and spreading there is still very important work, this.
In any specialized Wallpaper Store, you will see not only a table to assess the number of rolls you need, but, more importantly, the consultant who qualified will answer your questions.

Due to the losses for trimming, the actual area, which can be saved by one roll of wallpaper, will be '15% less than indicated on the roll. The percentage of trimming losses may increase depending on how much space is occupied by repeating wallpaper pattern. The magnitude of the "repeat of the pattern" is indicated on the wallpaper packaging. You can compensate these additional losses, adding the motion of the pattern to the measured value of the height of the room wall.

Measuring room size

Walls . Measure the wall length with an accuracy of up to 10 cm. (If the room will be covered with overalls, then sum up the length of all walls to determine the perimeter of the room.) This should also include the length of windows and doors. Measure the height to which the wallpaper will be glued, with an accuracy of 10 cm. When measuring the height, plinths and upper decorative linings are not taken into account. Ceiling. Measure the length and width of the ceiling with an accuracy of 10 cm.

How to measure non-standard surfaces

Speakers ceiling structural elements. If you glue the wallpaper on protruding ceiling structural elements, add the width and length of each side to the size of the measured area of \u200b\u200bthe wall.

Is your decision to do repair finally accepted? But you have not decided yet than to separate the walls? The least time-consuming and costly option is, of course, shove wallpaper.

The most serious problem in this work is to make the right calculation of the number of wallpapers on the room, so that it does not have to arrive with the shortage of them, because it is not always possible to find exactly the same. Reverse option when too many rolls were purchased, it's also hardly someone to please someone - this is the money thrown into the wind, two or three remaining rolls you just have no place to use.

In order to calculate everything correctly, it is necessary to measure the perimeter that forms the walls of the room. For those who no longer remember from school, recall: the perimeter of the rectangle is the sum of all his parties. For example, the walls have a length - two to 6 m and two to 4 m.

2 × 6 + 2 × 4 \u003d 12 + 8 \u003d 20 m is the length of the perimeter of the room. Naturally, you will have another number.

Then we measure the height of the walls. In standard apartments, it is usually 2.5 m. Since standard rolls have a length of 10 m, we divide 10 to the height of the walls - 2.5 m.

10: 2.5 \u003d 4 pcs., That is, from one roll, 4 wallpapers are obtained.

Of course, if the height of your walls is different, then the number of strips can also be different. For example, with the height of the walls, equal to 3 m, you will have only 3 bands and will remain 1 m, which can be used above door or window openings.

20: 0.53 \u003d 38.3 pcs. Rounding, we get 39 lanes of the wallpapers you need to wake the whole room.

Now the number of all bands will be divided by the number of bands in 1 roll.

39: 4 \u003d 9.7 - rounded round, we obtain 10 rolls of finishing material.

Of course, there are still door and window openings in the room. If they are not on the whole wall, they can not be taken into account, since there is always some minimal stock of wallpapers for every unforeseen case. Well, and if the openings are too big, their width can be deducted from the perimeter and then read according to the proposed scheme. But do not forget that the openings are usually not done at the entire height of the room, therefore, to make a plot over or under the opening, you will need a few more meters of material.

The number of rolls of non-standard width wallpaper - 0.68; 0.9; 1.06; 1.40 m is calculated in the same way, but instead of 0.53 m in the calculation we use the appropriate width.

By Square

Another simple way to calculate the number of wallpaper is to use in the calculation of the area of \u200b\u200bthe surface of the surface.

For example, take the same figures as in the previous embodiment: the width of the walls is 6 and 4 m, the height is 2.5 m.

2 × (6 + 4) × 2.5 \u003d 50 m 2. This is an area that needs to be caught by wallpaper. At the very beginning we were multiplied by 2, because we have two such walls.

Now we will learn the surface area of \u200b\u200bone roll, for this, its width to multiply for the length:

0.53 × 10 \u003d 5.3 m 2. That is, one roll of wallpaper can be saved 5 m 2 walls with a small residue, which is usually not taken into account.

50: 5 \u003d 10. We again turned 10 rolls.

For a more accurate calculation, it is possible to determine the area of \u200b\u200bopenings - door and window, and, if they are much larger than 5 m 2, then one can take place from the calculated number of rolls, since it has an area of \u200b\u200b5 m 2.

Such calculations can be done if the drawing on the wallpaper is small or often repeated, and it does not need to be customized.

With drawing

It is most difficult to calculate the required number of rolls of patterned wallpaper having a strict geometric or large drawing. They are glued, strictly observing the integrity of the drawing. Then the calculation of the number of rolls is made taking into account the rapport - the distances between the individual elements of the pattern or pattern. Rapport usually specified on the label laid in the package. Wallpaper with a large rapport give a lot of waste, so first count, how much will it cost you, and whether to buy them at all.

Learning to calculate the required number of wallpapers: Table and formula

In order to punish new wallpapers, it is not necessary to invite builders. Such a cosmetic repair can be made on its own. The main thing is to buy the right amount of material and carefully examine the instructions for gluing on the package. But how to correctly calculate how much wallpaper is on the room? Rules for calculating home repairs.

Measurement matters

The basis of construction calculations is precise measurements for which the construction roulette will need. First you need to measure the perimeter of the repaired room (the length of all walls) without taking into account the width of the windows and doors and the level of the walls. And then the length and height of the plots above and under the windowsides, as well as above the doors. Now go directly to calculations.

We derive the formula of the calculation

The resulting perimeter of the room is divided to the width of the selected wallpaper (it can be from 50 centimeters to the meter) and get the number of one-piece strips.

And the length of the roll is divided to 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 stripes).

After that, the total number of solid bands is divided into their own amount obtained from one roll. The result of arithmetic will be the number of rolls that are needed to cut only entire strips.

In order not to torment the calculator and do not bother the head with extra numbers, you can use the finished table (but it is worth considering that it, like any online service carries some error):

Correction for drawing products

Of course, when for repair, wallpapers are chosen that do not require fitting, everything is more or less simple. What should I do if the choice fell on a wall cover with a large drawing? In this case, it is less from the package to obtain a one-piece strip less (due to the need to customize the drawing). Consequently, the calculation must be adjusted.

Example calculation for persistent

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

Perimeter excluding the width of windows and openings: 3 + 3 + 4 + 4-0.8-1.2 \u003d 12 m

Number of solid cuts: 12: 0.6 \u003d 20 pieces

With the standard level of the ceilings of the room (2.5 m) from the package, 4 whole strips will be obtained (by the way, it is necessary to cut with a reserve, that is, the length of the piece must be not 2, 5 meters, and for ten centimeters more).

Number of packages for cutting whole bands: 20: 4 \u003d 5 pieces

With the size of the window of 0.8x1.5 and the doors, 2.1 m height, cropping from 5 rolls is enough to increase the space over functional openings, but for the space under the windows, you will have to buy another one (although you can take the wall under it composite piece). It means that you will need 6 monochrome rolls or 7 packs with a large pattern.

Wallpapers are the most popular means for decoration walls in residential premises. With their help, you can make absolutely any design in the room without resorting to excessive financial costs. When choosing wallpaper consumers encounter the problem of the right choice of rolls. How to calculate the number of wallpaper correctly?

What will be needed to calculate

Usually on the label from the roll indicates the approximate scheme for calculating the number of wallpaper. To find out the value yourself, you need to calculate the following parameters in advance:

• Surface surface of the walls.
• Roll width.
• Roll length.
• The height of the ceiling.

The lengths of the length and width of the wallpaper can be seen on the label when buying. Knowledge of magnitude will help correctly calculate the number of wallpapers on the room.

The main types of wallpapers depending on the width

Other 20 years ago, all wallpapers on the territory of the countries of the former USSR had standard length parameters and widths: 50 cm on 10 m. In the modern world, the market for repair materials implies a large number of various types of wallpaper. Consider the main of them:

• Standard rolls. They have a width of 50 to 55 cm. The most common type of wallpaper. Length parameters can vary from 8 to 12 m for wallpaper on paper or vinyl-based basis. If their base is tissue, then the parameters of the length will be 15 m. This type of wallpaper is optimal when there are 300 cm with ceiling heights.
• Roll of 60 cm wide. This type of wallpaper was widely distributed in the 90s. 20th century. However, now they are practically not used. The length value can be from 8 to 10 m.
• A roll of 74 cm wide. European style of wallpaper. They have standard length. It is 10 m.
• Meter rolls. Appeared about 10 years ago. However, the popularity has already gained. Roll width values \u200b\u200brange from 100-106 cm. Manufacturers produce meter wallpaper with different lengths of length. Standard from them - 10 m. Also produce rolls with a length of 12 and 25 m.

We learn the area of \u200b\u200bthe room

The main stages of the work:

1. Almighty plan room.
2. We carry out independent measurements.
3. We produce the necessary calculations.

Blacksmith planning room independently

How to calculate the number of wallpaper for one room? Before proceeding with work, you must prepare the following tools:

• Paper.
• Line.
• Pencil or pen.

It is necessary to draw the plan for all rooms indoors. This will require a ruler and pencil. It does not require absolute accuracy and scale ratio. The main thing is schematically to portray the room necessary for calculating.

After the walls are schematically depicted, the location of the windows and doors indoors should be specified on the plan. The values \u200b\u200bof scale and accuracy can also not be observed.

Independent measurements

How to calculate the number of wallpaper? To do this, find out the values \u200b\u200bof the parties 1 roll and the size of the surface area of \u200b\u200bthe room. To calculate the last number yourself, it is necessary to carry out the following actions:

1. For work it will be necessary roulette. With it, it is necessary to measure the length of the walls of the room. For this measurement is carried out along each wall. The height of measurements does not matter. It all depends on in which place to work is most convenient. You can measure the length along the plinth, you can in the middle of the wall or under the ceiling.
2. In the same way, we find the value of the height of the walls.
3. So that there are no errors in the calculation, it is recommended to measure all 4 walls of the room in a similar way. Then the values \u200b\u200bwill be the most faithful.
4. We measure the values \u200b\u200bof the height and width of doors and window openings using a roulette.
5. Calculate the area of \u200b\u200beach of the walls. For this, the length is multiplied by the resulting height value. The number found will show the area of \u200b\u200bone room wall. From it, it is necessary to take the value of the area of \u200b\u200bthe opening (window or door). To calculate its area, it is also necessary to find a product of the parties.
6. Similarly, you should find the area of \u200b\u200beach of the walls of the room. To find the total number of square meters to be pasted with wallpaper, the obtained values \u200b\u200bmust be summarized.

We learn the required number of rolls

To calculate, the value of the perimeter value is required. To find it, you need to get the sum of all the walls of the room.

The resulting perimeter must be divided into a width value of one roll. It is indicated on the label from the wallpaper. The resulting value will show how many wallpaper canvases will be required to enhance the entire room without taking into account window and door openings.

Next, it should be calculated, as many cloths are enough one wall roll. To do this, the value of the roll length should be divided into the height of the room. The resulting number will show how much strips will be from one roll.

How to calculate the number of wallpaper rolls to enhance the entire room? For this, the value obtained earlier the value of the total number of wallpapers should be divided into a set number of strips from one roll. The resulting value is rounded to an integer. We have determined the total number of rolls needed for one room.

Purchas wallpaper follows from all measurements. Compliance with these rules will learn how to correctly calculate the number of wallpaper for the room.
