How many wallpapers are needed by 11 squares. Calculation of the number of wallpapers on the room. We consider on your own fear and risk

Specify the necessary dimensions in meters.

Room sizes:

Y.- The length of the first side of the room, which must be saved by wallpaper.

X.- The length of the second side of the room under sticking.

H.- The height of the room.

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

D. - The distance from the beginning of the twinkle to the first angle. Value D. Measure from the beginning of sticking to the first angle (along the clockwise arrow), it cannot be equal to or larger than the length of the wall.

To implement the calculation, you can specify or the length of the walls of the room or its perimeter (in the second case, the option of the start of the adhesive will not be available).

If the room has rectangular or square outlines Enter the parameters Y., X., H.. For the premises of the wrong shape with protrusions and niches, there is a possibility of calculation, specifying the values H. and P..

Window:

If the room has a window opening, click "Add window" and enter it sizes: length WX. and height WY..

Wz.- The distance from the beginning of the wallpaper sticking determines the location of the window in the room. Enter the distance from the starting point of the pasting to the window.

The number of windows added is not limited.

Doors:

That the program takes into account the presence of a doorway when calculating must be pressed "Add doors"and introduce their lengths DXand height DY..

DZ. - The distance from the beginning of the wallpaper shook to the doors.

You can add multiple doors.

Wallpaper:

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

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

R. - Repeat pattern, or so-called. Rapport is the distance through which the same pattern is repeated.

Z. - stock for alignment, the allowance of the floor and the ceiling, which after gluing it is necessary to cut off the sharp knife for a rule or rule (0.05-0.15 m).

F. - shift the drawing. Mark this item, if you need to calculate, taking into account the Wallpaper Rappport shift for coincidence.

If you need to print the visualization, check the item " Black and white drawing"So you will get a drawing approximate to the requirements of GOST and save color paint or toner when printing.

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

Calculator will help calculate the full area of \u200b\u200bthe walls of the room (in m²), calculate the consumption of wallpaper with windows and doors. You will be aware of the square of one roll of wallpaper, the length of the webs of the specified height is needed for pasting, taking into account the cutting on trimming, as well as the amount of entire wallpaper wallpapers contained in the roll. What will be the residue from each roll and how many rolls (pcs) of a given length is necessary for pasting room. The calculator will calculate how much the wallpaper needs for the room and how many rolls need to be required, taking into account the presence of window and doorways. There will also be counted a common balance from all wallpaper.

Such data allow you to buy the right number of wallpapers for the room, taking into account the nuances and make the room shook with your own hands or hire professionals. It is advisable to have a margin in one roll over the calculated quantity, it will save time and money in the future, in case of incorrect cutting or damage.

Cosmetic or overhaul of the house should begin to prepare a preliminary estimate that can display the number and price of the necessary materials for restoration work. If you only decide to replace the wallpaper in the room, you need an accurate calculation of the number of rolls. This will allow you to purchase the required amount of material, save money and avoid possible problems.

How to start the calculation of wallpaper on the wall?

It is not strange, but for an accurate calculation you will not have to take for rolls and all sorts of ways to try to figure out how many square or vinyl, paper, fliesline or fiberglass.

Initially, it is necessary to find out the exact area of \u200b\u200bthe room, which we will hide. Of course, the floors do not need to be taken into account because we are interested in the walls and, perhaps, the ceiling, if you plan to decorate it in the tone of the walls. For measurements, it is enough to arm a tape measure and perform measurements throughout the perimeter of the walls.

To get the most accurate result, the promresses are performed twice: the first one near the plinths, and the second under the ceiling. Even with a small curvature of the walls there may be a discrepancy in the results. This will allow to identify the error that will have to be taken into account when calculating materials.

Quite often the situation occurs when the lower Promder at the Plinth showed the result of 8 meters. That is, each of the four walls has 2 meters. Accordingly, the room has the form of an ideal cube. But the promresses near the ceiling can be smaller for several centimeters. Leaving this, we can conclude that the room in the volume is not a cube, but a truncated pyramid or a prism. Even small discrepancies will lead to the fact that the corners of wallpapers at the top will have deviations from the general pattern of the material.

Because of this, wallpaper is worth sticking horizontally. The transverse imposition of the material will be able to hide the irregularities of the room. As a result, we can conclude that the promresses allow you to learn not only the perimeter of the room, but also to find out the true geometry of the room, respectively, you can find the most efficient finish option.

Further actions to calculate the number of wallpaper on the wall consist of a fairly simple miscalculation. For this, the obtained values \u200b\u200bare substituted in the formula S \u003d A * b. In this case, A and B are the sides of the rectangle, which the wall protrudes. After that, it is necessary to freeze window and doorways, their account is carried out with the help of this formula, only the values \u200b\u200bobtained are taking away from the entire area of \u200b\u200bthe wall. As a result, you can get quite accurate values \u200b\u200bof the number of wallpapers required for wall pasting.

To date, there are several options for calculating wall wallpapers:

By number of bands and the perimeter of the room.
According to the total area of \u200b\u200bthe walls that need to be saved.
When using a special online calculator.

To select the most optimal option for you, consider each of the options in more detail.

Calculation of wallpaper on the wall in the number of bands and the perimeter of the room.

This option provides for an accurate determination of the amount of material strips, which will be required for pasting a particular room. To do this, you must perform the following actions:

Initially measured the width and length of the room. Based on the data obtained, the total perimeter of the room is determined.
Also measured the width of the door and window opening. The obtained data must be deducted from the total perimeter.
After that, the value obtained is divided into the width of the wallpaper, which are planned to be used.
The resulting value is to round up to the whole value in the most side. This value and will be the number of bands that is necessary for the salary.
When you learned how many bands needed to a certain wall, this value must be divided into one roll length.
That the material is enough, the obtained values \u200b\u200bare rounded into the biggest side.

Thus, you can get an exact number of bands and rolls of wallpaper. To get acquainted in more detail with the calculation methodology, it is necessary to consider all the steps on a specific example.

Example of calculation. If you need to leave the room with dimensions of 7 m per 3 m and the height of the walls of 2.5 m, which has a window opening 2 m per 1.5m and door 1 m per 2 m, and it is necessary to set the dimensions of the wallpaper roll: length 10m, and Width 53 cm.

To calculate the required number of rolls, you will need to perform the following manipulations:

Determination of the perimeter of the entire room: (7 + 3) x2 \u003d 20 meters.
Calculation of the width of the door and window opening: 3 + 1 \u003d 3 meters.
Calculation of the total perimeter with a deduction of openings: 20-3 \u003d 17 meters.
The resulting value must be divided into the roll width of the material: 17 / 0.53 \u003d 32. The result shows that 32 bands of selected wallpaper will be required to this room.
To calculate the number of bands in a roll, it is worth splitting the total length of one roll to the height of the wall: 10 / 2.5 \u003d 4. This suggests that in one roll of 4 bands.
The last step is the separation of the number of all bands, by the number of segments in one roll: 32/4 \u003d 8.

Pretty simple mathematical calculations will allow you to answer that 8 rolls of selected wallpaper will be required for pasting this room. It should be remembered that this method of miscalculation does not take into account the required amount of material under both equestrian and doorways. Accordingly, buying a little more material.

Calculation of the number of wallpapers on the area of \u200b\u200bthe surfaces of the surfaces.

This is a share of an economical and accurate method of calculation, especially when it comes to a room with a large area. This option is based on the definition of the entire area of \u200b\u200bthe wall surfaces to be saved.

To do this, you must perform the following actions:

Initially, the entire perimeter of the room is washed and multiplied to the height of the walls.
It also costs to calculate the doorways of the doors and windows. The obtained data should be subtracted with the total area of \u200b\u200bthe room, which will obtain the exact value of the surfaces of the surfaces.
To calculate the area of \u200b\u200bthe web used material, it is sufficient to multiply the roll length on its width.
After that, the magnitude of the total area of \u200b\u200bthe room is to divide into the material area in one roll.
The obtained values \u200b\u200bmust be rounded up to the zoom. This data will be the number of rolls.

Consider this method of miscalculation on a specific example. Data Take the same as for the first option.

To measure the perimeter: (7 + 3) x2 \u003d 20 meters.
The area of \u200b\u200bthe salary is calculated by multiplying the perimeter to the height of the wall: 20 * 2.5 \u003d 50qm.
The total area of \u200b\u200bthe room without door and window openings: (2 * 1.5) + (1 * 2) \u003d 5kv.m.
As a result, you can get the exact number of areas that need to be saved: 50-5 \u003d 45 sq.m.
As for calculating the wallpaper canvase in one roll, then it is necessary to multiply its length to the width: 10 * 0.53 \u003d 5.3 sq.m.
The last step is the separation of the area of \u200b\u200bone roll on the total area of \u200b\u200bthe room: 45 / 5.3 \u003d 8.4. Thus, we found out that the room will require 8.4 rolls of selected wallpaper. As a result, it is necessary to round the data obtained and acquire 9 rolls of material.

The examples showed that the results of the first and second option are almost identical. In this case, the second method allows you to take into account space under and above the openings. By virtue of this, it can be concluded that the calculation itself is not very complex and both options can be applied in practice.

Calculation of wallpaper on the wall using an online calculator.

If there is no possibility or desire to carry out independent calculations of the necessary materials for sticking the room, you can use a special online calculator. To date, there are a lot of sites on the Internet, which allows for free to use this service.

For settlements will have to carry out small dimensions of the room that will need to be introduced into the program, namely:

Length and width of the room.
Height of walls from floor to ceiling.
Length and width of the wallpaper rolls that are planning to use for pasting.

All of the above parameters must be entered into the appropriate online calculator fields. After that, you can get the finished result of the required number of wallpaper.

It should be noted that it is quite often for the pasteing room used wallpapers with drawings that must be docked from the adjacent web. Accordingly, the calculation must be done from the magnitude of the report (size of the ornament or pattern). Some online calculators have the ability of this type of miscalument, which will significantly save time, strength and money.

Features of applying different ways to calculate wallpaper for walls

All the above options for calculating the material for the walls allow you to quite accurately figure out the number of necessary wallpaper. But this is only if the walls of the room have perfectly smooth parameters, and the wallpaper themselves do not have large drawings that require additional fit when salabing.

If the walls have protrusions or niches, their dimensions should also be considered when calculating. To do this, you need to make the appropriate marks or record.

A more difficult task is to calculate the number of wallpaper with large drawings. When pasting, these materials require the fittings of the canvas at a certain distance. This period of drawing, which is repeated, is called the report. For miscalculations to be accurate to each roll of wallpaper add one length of the report, as a rule, it does not exceed 25 centimeters. Quite often, this parameter manufacturer indicates the packaging of the material. If there is no value, then you can spend the measurements yourself using a roulette.

In this case, a 10-meter roll that is used to the height of the wall 2.5 meters will have three strips, and not four, as it was calculated initially. All this must be taken into account in order to avoid trouble and additional costs later. As practice shows if you plan to leave a room at 23-25 \u200b\u200bsq.m., it is worth buying two rolls of wallpaper. If the room is greater, for every 6 rolls it is necessary to add another one.

The apartment repairs are starting with preparatory calculations, the determination of the consumable material in the necessary quantities that may be needed in the process of performing wall coating finish. Before starting the wing of walls in the apartment with new wallpaper, originally determine the type of finishing material and its amount for the salary. The calculation should be made carefully in order to avoid additional problems in repair activities and unnecessary material costs. Calculate how many wallpapers need a calculator will help in any room.

How to correctly determine the number of rolls

Before buying new wallpapers for wall pasting, it is necessary to make an accurate calculation of the required amount of material. Wrong counting leads to a shortage or residues of excess purchased raw materials. When determining the required amount of raw materials, the size of the walls of the walls in the room is calculated, and then the parameters of the doors and windows are subtracted from them. The next action makes division of the result obtained by the value of the calculated area of \u200b\u200bthe new roll.

The calculation formula is not very complex:

The number of rolls \u003d s v .: S steering. x K.

S bt. - area of \u200b\u200bfour walls;

S steers. - the area of \u200b\u200bthe entire roll, this value is obtained by multiplying the roll length on their width, the standard length is about 10 meters, the width is indicated on the package;

k - Coeff. Stock applies to take into account the flow rate of the corners, crop, to repeat the pattern. It is 1.1-1.2.

The number of rolls of wallpaper on the room Calculator will consider if there is no desire to calculate with the help of the formula.

Such a calculation is in demand when planning the walls of the walls on their own or when contacting professional masters, since this calculation can be provided for the cost of buying materials.

Source values \u200b\u200bfor calculating wallpaper

Basic data for the calculation of the finishing material:

the perimeter of the walls (the sum of all lengths in meters);
room height;
sheet width (the most common sizes 0.5; 0.56; 0.6; 0.75 meters);
length in one package (the most common samples are 7; 10.5; 12 and 18 meters);
how many windows in the room;
length and width of the window;
number of doors;
width and height of the door.

The size of the area of \u200b\u200bwindows and doors is needed to exclude them from the result obtained.

Features of working with a large ornament on the wallpaper

You always need to take into account the drawing on the wallpaper. During coloring that does not require docking and adaptation, the amount of material obtained using the calculation calculation can be purchased. In this case, additional calculations are not needed.

When choosing a material with large ornament fragments, docking is required, the standard actions using the calculation are not appropriate. Practically masters are recommended to add two rolls if the room is no more than 22 square meters.

It is necessary to take into account patterns - waste is directly proportional to the size of the rapport. It is indicated on the packaging label. Rapport is the frequency of repetition of the fragment on the chopler. The drawing must be properly combined between adjacent canvas.

Tip: Choosing a wobbly material needs to closely monitor the number of the series indicated on the labels so that there are no differences in the shade and saturation of the color in different packages.

Choosing the right calculator

The calculator makes the calculator with an increase of 10 cm for one sliced \u200b\u200bstrip of the workpiece.

The wallpaper calculator calculator allows you to quickly determine the number of wallpapers in rolls and square meters, it allows you to reduce the time to prepare for the main work. An online calculator makes a calculation with the savings of raw materials, subtracting windows and doors, adding 10% for possible marriage and trimming. After receiving the calculated result, it is necessary to round it up to the whole roll.

Tip: When choosing a suitable calculator for counting wallpaper, you need to make sure that it is able to take into account not only the usual parameters of the room, but also can produce complex calculations, taking into account the magnitude of the rapport, roll parameters. The magnitude of the rapport is added to the length of each segment of the wallpaper for the convenience of comparing ornament on the adjacent canvases.

When choosing wallpaper with large drawings, plants and other complex forms, you must calculate the number of rapports per sliced \u200b\u200bcloth. The number of rolls directly depends on how great the period of repetition of the same pattern will be. The product label contains information about the magnitude of the rapport.

With a calculation account, the size of niches, protrusions and other complex areas in the premises are not taken into account. Decision is made, make places closed with furniture, racks, wardrobes. There are even places for single chests or buffets.

Wallpaper Calculator for the Room Square calculates the consumption of materials with the most simplified way. It is enough to make a measurement along the plinth with a roulette. The length of all four walls, height from the floor to the ceiling, specify the length and width of the selected finishing material. As a result, a very approximate calculation of the number of wallpapers for this dwelling is performed.

Wallpaper Calculator, taking into account the door, has the ability to produce a more economical calculation, taking into account the area of \u200b\u200bthe doorway, which does not require the salary. When calculating the flow of wallpaper, doors sizes are deducted from the general result.

In order to more accurately determine the desired amount of finishing material, the wallpaper calculator is used based on windows. Data lengths, widths and quantities of window openings are taken into account with a general count. This method allows you to get a more accurate budget result.

Calculation Calculator Wallpaper online gives the most correct result. It helps to accurately calculate the following values:

the number of wallpapers in rolls and square meters required for the room salary;
the amount of the required glue;
amount of money for the purchase of all materials;
the size of the residual pieces after work produced in square meters and rolls.

For a detailed operational calculation, you need to enter the necessary data into special columns:

length and roll width in meters;
the size of the stuck field, if the blending will be made by the brass;
the price of one roll;
the cost of adhesive material;
the magnitude of the rapport indicated on the package;
length and height of each wall in meters;
the width and height of the window in meters;
number of windows;
height and width in doors meters and their number.

After filling out all the necessary graph, it is enough to click the "Calculate" button and get reliable information.

Tip: If the wall of the room is made with niches or protrusions, then their detailed parameters need to be added to the total length of the wall. Wallpapers are spent in more quantities due to the processing of additional corners. When buying, you need to purchase two rolls in the case of damage to the coverage on the walls as a result of repair work, children's pranks or pets. Purchase how many wallpapers need

Simplified calculation method

When choosing wallpapers that do not require docking and fitting the ornament, the calculation is simpler:

The calculator himself will find the perimeter of the room, folding the length of all four sides.
Determine the number of finished canvases for this room, dividing the perimeter magnitude to the width of the sheet.
Calculate how many panels are placed in general roll, sharing the actual size of the roll length to the height of the wall. At the same time will show the number of cropping materials.
Calculate the number of rolls for this room, by dividing the total number of cloths on their number in one roll.

Wallpaper calculation Online calculator will quickly and do not need to multiply and divide on paper in a column.

Traditionally, the repair of the room is not without changing the wallpaper. But the market for modern finishing materials presents many wallpaper of different types, colors, sizes and other characteristics. How to optimally calculate the required amount of this material?

So, it was decided to change the wallpaper, but how it is better to make the calculation of the necessary materials to and not overpay, and then do not bother the missing number (especially since the parties of the same wallpaper may differ in color, drawing, texture)? Is there a general principle of calculations for any type of wallpaper or need to be calculated in different ways, depending on which wallpapers will be used?

First you need to decide:

for which room it will takes the calculation of wallpaper (living room, entrance hall, kitchen)
what type of wallpaper is planned to be used (paper, phlizelin, bamboo, liquid, etc.)
what are the size of the wallpaper (length, width), drawing, texture
whether besides the walls, it is still a ceiling with wallpaper.

Depending on what room is planned to glue wallpaper, the type is selected. For example, velor wallpaper can be used in the hall, and in the kitchen they will be impractical and inappropriate, washing coatings will be more suitable in the corridor. Not only the dimensional, but also the qualitative characteristics of the wallpaper cannon can affect the calculations.

On the calculation of the number of wallpapers affects the following:

sizes (length, width) wallpaper
design, drawing, texture, wallpaper type
the area of \u200b\u200bthe surface is covered
surprise surface
availability of doors, windows, protrusions, arches, etc. in the room
designer solution in the room design (sometimes different colors and types of wallpaper are used).

Of course, rooms are different, rolled wallpapers are also of different lengths. There is a general formula that acts for any type of wallpaper:

R: Q: 3 (or 4 - depending on whether the drawing fit is needed or not).

Where p is the perimeter of the room, B - the width of the roll.

The digit obtained according to this formula is rounded to a larger number. Of course, more accurate measurements will also need more accurate calculation for fans, and accounting for other parameters.

How to calculate the required number of rolls.

To correctly calculate, it is not necessary to specifically invite builders, all calculations can be made independently. The main thing - you need to measure everything. Therefore, it is necessary to arm a construction tape measure and measure the perimeter of the room in which the repair is planned (this is the length of all walls minus the size of the windows and doors).

It happens, in the room not the entire surface plan to be accumulated with wallpaper (for example, the calculation is carried out for the kitchen, and the wallpaper will be glued together with the tile) then you need to find the area that the tile apron will occupy, from the area of \u200b\u200bthe whole room.

It is important to consider: if the wallpaper is selected with a pattern, then their flow increases by 1.5 times, since the fitting fit will be required.

For the correct calculation of the wallpaper, it is important to know the exact dimensions of the room, the number and area of \u200b\u200bwindow and doorways.

2Ah + 2bh \u003d s

S is the desired total area of \u200b\u200bthe room,
N - room height,
A - Length of the room,
B - width of the room.
If the length of the walls is not the same, and their number is not 4, but, for example, 5, it is not necessary to multiply into two, and the formula may be like this:

S \u003d AH + BH + CH + DH. And here: a - the length of the first wall, in the second, s - third, d - fourth.

This formula is suitable if the height of the walls is the same, and their lengths differ. If the height is different (for example, there may be a podium, steps), then you need to specify it different.

It is important to consider:

So that the calculations were accurate, it is necessary to measure it out of eyes, steps, elbows (all the more so that steps and elbows can be different in humans), but a rulette, tape measure.
The results of measurements are better to record in centimeters and rather as possible, not rounded.

Methods of calculation

1 way (according to old wallpaper).

If old wallpapers remained in the room and they coincide with the new ones, and the drawing of the drawing is not necessary, you can simply measure the height of the wall, find out which roll length in new wallpaper (rolls are now available at 18, 12, 10, 7 meters) And calculate the number of strips of old wallpapers on the walls. Dividing the length of the roll to the height of the wall, we learn how many panels will turn out in one roll. Well, here it is easy to calculate the required number of rolls.

Suppose, the height of the walls is 2.5 m, the roll is 10 m, the strips of old wallpaper - 20 pcs.
10: 2.5 \u003d 4 (the number of cloth in one roll).
If only 20 segments, then dividing to 4, we get 5 rolls required for pasting the entire room.

If the number happened fractional, then it is usually rounded into the biggest side.

2 method (calculation "from scratch").

If there are no longer in the wallpaper room, the walls are cleaned, then in the calculations you can act like this:

We find the area of \u200b\u200beach wall. Pre-measure its length, width and redress.
In the case of window or doorways in the wall, we calculate and subtract their area from the total area of \u200b\u200bthe wall.
If any decor is planned, and it will occupy a space where the wallpaper will not be needed, also deduct the area of \u200b\u200bthis surface from the total area of \u200b\u200bthe wall.
We summarize the results obtained for all walls.
Knowing the length and width of the wallpaper in the roll, we can count the area of \u200b\u200bthe wallpaper.
Sharing the area of \u200b\u200bthe room to the Roll Square, we learn the right number of rolls.

The same wallpapers, if they were released at different times, may differ with shades.

Calculation for wallpaper

If the drawing is pale or not very noticeable, you can act in general scheme, but it is bright and noticeable, you will have to take into account the ornament step. Usually the ornament step is 52-53 cm.

Plan of calculations:

We measure the height of the wall.
We divide on the ornament step.
We are rounded the value to the biggest and get the number of rapport.
We multiply the resulting number of rapport on its magnitude and we finish the length of the panels cut off from the roll.
To find out the number of waste, you need to take away from the resulting panel wall height of the wall.
Further, dividing the length of the roll to the length of one panel, we obtain a coefficient that will help determine the amount of rolls required.
The resulting coefficient is multiplied by the difference, which turned out in paragraph 5.
The number obtained in paragraph 7 is deducted from the total roll length.
If the total area of \u200b\u200bthe room, which is planned to be caught, divided by the number of paragraph 8, just the required number of rolls.

Suppose:

roll length of wallpaper that plan paste, 10m,
pitch of the ornament - 0, 53 m,
the height of the wall is 2.8 m,
the total area of \u200b\u200bthe room is 43 sq.m.

Calculations will be as follows:

2.8 m.
2,8: 0,53 = 5,28
Round up to 6.
6x 0.53 \u003d 3.18.
3.18 - 2.8 \u003d 0.38m (or 38 cm).
10: 3,18 \u003d 3.14 (coefficient).
3.14 x 0.38 \u003d 1,19
10 - 1,19 \u003d 8.81m.
43: 8.81 \u003d 4.8 (i.e., optimally 5 rolls will be required to the room in this example).

Rolls are of different dimensions, but these methods of calculations are suitable for any wallpaper: just need to substitute those numbers that reflect the dimensions of the selected wallpaper.

Calculation of the required amount of liquid wallpaper.

If liquid wallpapers are chosen to finish the room, then the specifics of the calculations change slightly, but the total area of \u200b\u200bthe working surface is still necessary.

To determine the amount of liquid wallpaper, you need the area of \u200b\u200bthe walls (how to find out, explained above) to divide on the consumption of wallpaper of one package. Usually, on each package of liquid wallpapers, this consumption is indicated, but on average it is 3-5 sq.m. Surfaces.

For example, if the area of \u200b\u200bthe working surface in the room is 30 square meters. m., then with an average consumption of liquid wallpapers in one package of 3 sq. M., 10 packages of such wallpapers will be required.

Depending on the experience of working with liquid wallpaper and from the status of the walls, it is recommended to take 1-3 package.

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.
Now it came to count the number of incomplete segments. We produce the calculation on the same principle, and the result is plus to the already available figure.

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.

I think it is still better to calculate the wallpaper. And then, if the wallpaper is drawing, threw how many rolls need to be purchased additionally. I change the wallpaper once every 5 years. As a rule, I take 1 roll on the reserve. Change the wallpaper, and the mood changes for the better.

Personally, I always count on the number of rolls yourself. And do not trust the tables. In the case of monophonic wallpaper, they are suitable. But if the drawing needs to be chosen, then it is easy to make it easier.
And it is always necessary to ensure and take a roll more. The desired wallpapers find quite simple. 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.

Let it be better than the way that there are situations (canceled vacation, work appeared) when you buy wallpaper and glue them in six months. Then you detect that it was not enough of the literally one roll, but the range in the stores has already changed. So in the situation, from which the way out is very difficult to find.
