How to measure wallpaper for a room. How to calculate the required number of wallpapers? Rules for mixing liquid wallpaper

Cosmetic or major repairs to the house should begin with the preparation of a preliminary estimate that can display the quantity and price of the necessary materials for restoration work. If you decide to only replace the wallpaper in the room, you will 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 calculating wallpaper on the wall?

Strange as it may seem, but for an accurate calculation, you do not have to take rolls and try in every possible way to find out how many square or linear meters of vinyl, paper, non-woven or fiberglass are in them.

Initially, it is necessary to find out the exact area of ​​\u200b\u200bthe room that we will paste over. Of course, floors do not need to be taken into account, since we are interested in the walls and, possibly, the ceiling, if you plan to decorate it to match the walls. For measurements, it is enough to arm yourself with a tape measure and take measurements around the entire perimeter of the walls.

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

Quite often, a situation arises when the lower measurement at the plinth showed a result of 8 meters. That is, each of the four walls has 2 meters. Accordingly, the room has the shape of a perfect cube. But measurements near the ceiling can be several centimeters smaller. Based on this, we can conclude that the room in volume is not a cube, but a truncated pyramid or prism. Even small discrepancies will lead to the fact that the corners of the wallpaper at the top will deviate from the general pattern of the material.

Because of this, wallpaper should be glued horizontally. The transverse overlay of the material can hide the unevenness of the room. As a result, we can conclude that measurements allow you to find out not only the perimeter of the room, but also to find out the true geometry of the room, respectively, you can choose the most effective finishing option.

Further steps to calculate the number of wallpapers on the wall consist of a fairly simple miscalculation. To do this, the obtained values ​​​​are substituted into the formula S \u003d a * b. In this case, a and b are the sides of the rectangle that the wall protrudes. After that, it is necessary to measure window and door openings, they are calculated using this formula, only the obtained values ​​\u200b\u200bare subtracted from the entire area of ​​\u200b\u200bthe wall. As a result, you can get fairly accurate values ​​for the amount of wallpaper needed for pasting the walls.

To date, there are several options for calculating wallpaper on the wall:
  1. By the number of stripes and the perimeter of the room.
  2. According to the total area of ​​\u200b\u200bthe walls that need to be pasted over.
  3. When using a special online calculator.

To choose the best option for you, consider each of the options in more detail.

  1. Calculation of wallpaper on the wall by the number of stripes and the perimeter of the room.

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

  1. Initially, the width and length of the room are measured. Based on the data obtained, the total perimeter of the room is determined.
  2. The width of the door and window opening is also measured. The data obtained must be subtracted from the total perimeter.
  3. After that, the resulting value is divided by the width of the wallpaper roll that is planned to be used.
  4. The resulting value should be rounded up to an integer value. This value will be the number of stripes required for gluing.
  5. When you know how many strips are needed for a particular wall, this value must be divided by the length of one roll.
  6. In order to have enough material, the obtained values ​​are rounded up.

In this way, the exact number of strips and rolls of wallpaper can be obtained. In order to get acquainted with the calculation methodology in more detail, it is necessary to consider all the steps on a specific example.

Calculation example. If you need to paste over a room with dimensions of 7 m by 3 m and a wall height of 2.5 m, which has a window opening of 2 m by 1.5 m and a doorway of 1 m by 2 m, you must specify the dimensions of the wallpaper roll: length 10 m, and width 53 cm.

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

  1. Determination of the perimeter of the entire room: (7 + 3) x2 \u003d 20 meters.
  2. Calculation of the width of the door and window opening: 3 + 1 = 3 meters.
  3. Calculation of the total perimeter minus openings: 20-3=17 meters.
  4. The resulting value must be divided by the width of the material roll: 17/0.53=32. The result shows that 32 strips of the selected wallpaper will be required for this room.
  5. To calculate the number of strips in a roll, it is worth dividing the total length of one roll by the height of the walls: 10/2.5=4. This indicates that there are 4 strips in one roll.
  6. The last step is the division of the number of all strips into the number of segments in one roll: 32/4=8.

Pretty simple mathematical calculations will allow you to get the answer that 8 rolls of the selected wallpaper will be required to paste this room. At the same time, it is worth remembering that this calculation method does not take into account the required amount of material under and above horse and door openings. Accordingly, you will have to buy a little more material.

  1. Calculation of the number of wallpapers on the walls by the area of ​​the pasted surfaces.

This is a more economical and accurate calculation method, especially when it comes to a room with a large area. This option is based on determining the entire area of ​​the wall surfaces that need to be pasted over.

To do this, you must perform the following steps:

  1. Initially, the entire perimeter of the room is measured and multiplied by the height of the walls.
  2. At the same time, it is also worth calculating the openings of doors and windows. The data obtained must be subtracted from the total area of ​​\u200b\u200bthe room, which will allow you to get the exact size of the surfaces to be glued.
  3. To calculate the area of ​​​​the web of the material used, it is enough to multiply the length of the roll by its width.
  4. After that, it is enough to divide the total area of ​​\u200b\u200bthe room by the area of ​​\u200b\u200bthe material in one roll.
  5. The values ​​obtained must be rounded up. This data will be the number of rolls.

Consider this method of miscalculation on a specific example. We take the same data as for the first option.

  • To measure the perimeter: (7+3)x2=20 meters.
  • The pasting area is calculated by multiplying the perimeter by the height of the walls: 20 * 2.5 \u003d 50 sq.m.
  • The total area of ​​the room without door and window openings: (2*1.5)+(1*2)=5 sq.m.
  • As a result, you can get the exact amount of area that needs to be pasted over: 50-5 = 45 sq.m.
  • As for the calculation of the wallpaper in one roll, for this it is necessary to multiply its length by the width: 10 * 0.53 \u003d 5.3 sq.m.
  • The last step is the division of the area of ​​​​one roll into the total area of ​​\u200b\u200bthe room: 45 / 5.3 = 8.4. Thus, we found out that 8.4 rolls of selected wallpaper will be required per room. As a result, it is necessary to round the received data and purchase 9 rolls of material.

The given examples show that the results of the first and second variants are almost identical. In this case, the second method allows you to take into account the space under and above the openings. Because of this, we can conclude that the calculation itself is not very complicated and both options can be applied in practice.

  1. Calculation of wallpaper on the wall using an online calculator.

If there is no possibility or desire to independently calculate the necessary materials for gluing a room, you can use a special online calculator. Today, there are a lot of sites on the Internet that allow you to use this service for free.

To carry out the calculations, you will have to take small measurements of the room, which will need to be entered into the program, namely:
  1. The length and width of the room.
  2. Wall height from floor to ceiling.
  3. The length and width of the wallpaper roll that you plan to use for pasting.

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

At the same time, it is worth noting that quite often wallpaper with drawings is used for pasting a room, which must be joined with an adjacent canvas. Accordingly, the calculation must be carried out from the size of the report (the size of the ornament or pattern). Some online calculators have the possibility of this type of calculation, which will save a lot of time, effort and money.

Features of the use of different methods for calculating wallpaper for walls

All of the above options for calculating the material for the walls allow you to quite accurately determine the amount of wallpaper needed. But this is only if the walls of the room have perfectly even parameters, and the wallpaper itself does not have large patterns that require additional adjustment when pasting.

If the walls have ledges or niches, their dimensions must also be taken into account in the calculation. To do this, make appropriate notes or records.

A more difficult task is to calculate the number of wallpapers with large patterns. When pasting, these materials require adjustment of the canvases at a certain distance. This interval of the pattern, which is repeated, is called a report. In order for the miscalculations to be accurate, one report length is added to each roll of wallpaper, as a rule, it does not exceed 25 centimeters. Quite often, the manufacturer indicates this parameter on the packaging of the material. If the value is missing, then you can take measurements yourself using a tape measure.

In this case, a 10-meter roll, which is used for a wall height of 2.5 meters, will have three strips, and not four, as was originally calculated. All this must be taken into account in order to avoid troubles and additional costs in the future. As practice shows, if you plan to paste over a room of 23-25 ​​sq.m., it is worth buying two additional rolls of wallpaper. If the room is larger, add one more for every 6 rolls.

How to find out how much wallpaper you need per room? The amount, of course, depends on the size of your room. To determine the required number of trellises, we need to calculate the perimeter or area.

What is needed for this?

Firstly, this is a tape measure for measuring the room, secondly, a notebook or notepad to record the measurement results, and finally, a calculator.

Calculation of wallpaper by room area and perimeter. Simple and clear table.

First you need to measure the length and height of the room where you are going to glue the wallpaper. It is also worth measuring the door and window openings. This will help improve the calculation.

First you need to calculate the perimeter of the room:

P = (L of one wall + L of adjacent wall) * 2
P is the perimeter;
L is the length.

Estimated web length, how to calculate?

To accurately know the length of the wallpaper, you must use the formula:

Estimated strip height = room height + ornament pitch (rapport) + margin for upper and lower allowances (5 cm)

Work begins by measuring the width of the wallpaper strips you have chosen. After that, count how many strips you need to paste the room:

N stripes per room = P / wallpaper stripe width

Counting from one roll.

Find out the length of the roll, which is indicated on the label. And then calculate according to the formula:

N strips from 1 roll = L roll / calculated strip height

N is the quantity.

Calculation of wallpaper rolls per room.

After all the work done, we will find out how many rolls are needed for pasting the room:

N rolls = N strips per room / N strips from 1 roll

Calculation of wallpaper by the area of ​​the room.

Since, the calculation along the perimeter may not always be relevant, because the number of doors and windows is not included in the calculation, because of this, the amount is calculated by area.

We measure the area of ​​\u200b\u200bthe walls using the following formula:

SO = L wall * H wall
S is the area;
SO - total area;
H is the height.

You also need to calculate the area of ​​\u200b\u200bthe walls on which you will glue the wallpaper. But before that, you need to calculate the sum of door and window openings. And then use this formula:

S wallpapering \u003d SO - S windows and doors

If the roll fits the standard 53 cm wide and 10 m long, it is designed for approximately 5 sq.m. rooms.

To calculate you need:

N rolls = S rooms / S that can be glued with 1 roll

Is there a pattern on your wallpaper?

If there is a drawing on your wallpaper, first of all you need to find out its report, and then calculate the final ceiling height for it and carry out the calculation along with it.

Using tables

In order to use the table, you need to know the perimeter and area of ​​​​the room. It depends on which table you need to use.

Calculation by area, table:

To use this kind of table, you must know the height and square of the room. And then you can easily find out the required number of rolls.

To use the table below, you need to calculate the width of the stripes and the length of the wallpaper you have chosen. After that, you need to measure the height of the ceiling and look at the table, how many rolls you will need.

Roll size (strip width / roll length = pasting area): 0.53 m / 10.05 m = 5.33 sq.m

Traditionally, renovating a room is not complete without changing the wallpaper. But on the market of modern finishing materials there are many wallpapers 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 what is the best way to calculate the necessary materials so that you don’t overpay too much, and then don’t buy the missing amount (especially since batches of the same wallpaper can differ in color, pattern, texture)? Is there a general calculation principle for all types of wallpaper, or does it need to be calculated differently, depending on which wallpaper will be used?

First you need to decide:

  • for which room you need to calculate the wallpaper (living room, hallway, kitchen)
  • what type of wallpaper is planned to be used (paper, non-woven, bamboo, liquid, etc.)
  • what are the dimensions of the wallpaper (length, width), pattern, texture
  • will they also wallpaper the ceiling in addition to the walls.

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

The calculation of the number of wallpapers is affected by the following:

  • dimensions (length, width) of wallpaper
  • design, pattern, texture, wallpaper type
  • glued surface area
  • surface evenness
  • the presence of doors, windows, ledges, arches, etc. in the room
  • design solution in the design of the room (sometimes different colors and types of wallpaper are used).

Of course, the rooms are different, roll wallpaper is also of different lengths. There is a general formula that works for any type of wallpaper:

R: V: 3(or 4 - depending on whether the pattern needs to be adjusted or not).

Where P is the perimeter of the room, B is the width of the roll.

The figure obtained by this formula is rounded up to a larger number. Of course, for fans of more accurate calculations, more accurate measurements and consideration of other parameters will be needed.

How to calculate the required number of rolls.

In order to correctly calculate, it is not necessary to specially invite builders, all calculations can be done independently. The main thing is to accurately measure everything. Therefore, it is worth arming yourself with a construction tape measure and measuring the perimeter of the room in which repairs are planned (this is the length of all walls minus the size of windows and doors).

It happens that in the room they do not plan to wallpaper the entire surface (for example, the calculation is for the kitchen, and the wallpaper will be glued along with the tiles), then you need to subtract the area that the tiled apron will occupy from the area of ​​​​the entire room.

It is important to consider: if a wallpaper with a pattern is chosen, then their consumption increases by 1.5 times, since the pattern will need to be adjusted.

For the correct calculation of wallpaper, it is important to know the exact dimensions of the room, the number and area of ​​window and door openings.

2AH + 2BH=S

S is the desired total area of ​​​​the walls of the room,
H is the height of the room,
A is the length of the room
B is the width of the room.
If the length of the walls is not the same, and their number is not 4, but, for example, 5, then you do not need to multiply by two, and the formula can be as follows:

S = AH + BH + CH + DH. And here: A is the length of the first wall, B is the second, C is the third, D is the fourth.

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

It is important to consider:

For the calculations to be accurate, you need to measure not by eye, steps, elbows (especially since steps and elbows can be different for people), but with a ruler, a tape measure.
It is better to record the results of measurements in centimeters and as accurately as possible, do not round.

Calculation methods

1 way (on old wallpaper).

If there are old wallpapers left in the room and they are the same width as the new ones, and you don’t need to combine the pattern repeat, then you can simply measure the height of the wall, find out how long the roll is in the new wallpaper (rolls of 18, 12, 10, 7 meters are now produced) and count the number of strips of old wallpaper on the walls. By dividing the length of the roll by the height of the wall, we find out how many panels will turn out in one roll. Well, here it is already easy to calculate the required number of rolls.

  1. Let's say the height of the walls is 2.5 m, the roll is 10 m, the strips of old wallpaper are 20 pcs.
  2. 10: 2.5 = 4 (number of panels in one roll).
  3. If there are 20 segments in total, then dividing by 4, we get 5 rolls necessary for pasting the entire room.

If the number turned out to be fractional, then it is usually rounded up.

Method 2 (calculation "from scratch").

If there is no longer wallpaper in the room, the walls are cleared, then in the calculations you can proceed as follows:

  1. Find the area of ​​each wall. Pre-measure its length, width and multiply.
  2. If there are window or door openings in the wall, calculate and subtract their area from the total area of ​​the wall.
  3. If any decor is planned, and it will occupy a space where the wallpaper will not be needed, we also subtract the area of ​​\u200b\u200bthis surface from the total wall area.
  4. We summarize the results obtained for all walls.
  5. Knowing the length and width of the wallpaper in a roll, we can calculate the area of ​​the wallpaper.
  6. Dividing the area of ​​​​the room by the area of ​​\u200b\u200bthe roll, we find out the required number of rolls.

The same wallpaper, if released at different times, may differ in shades.

Calculation for wallpaper with a pattern

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

Calculation plan:

  1. We measure the height of the wall.
  2. We divide the ornament by a step.
  3. We round the value up and get the rapport number.
  4. We multiply the resulting rapport number by its value and as a result we get the length of the panel cut off from the roll.
  5. To find out the number of waste, you need to subtract the height of the wall from the resulting length of the panel.
  6. Further, dividing the length of the roll by the length of one panel, we obtain a coefficient that will help determine the number of rolls required.
  7. The resulting coefficient is multiplied by the difference, which was obtained in paragraph 5.
  8. The number obtained in paragraph 7 is subtracted from the total length of the roll.
  9. If the total area of ​​\u200b\u200bthe room that is planned to be pasted over is divided by the number from clause 8, the required number of rolls will be obtained.

Let's say:

  • length of a roll of wallpaper to be pasted, 10m,
  • ornament pitch - 0.53 m,
  • wall height 2.8 m,
  • the total area of ​​the room is 43 sq.m.

The calculations will be as follows:

  1. 2.8 m
  2. 2,8: 0,53 = 5,28
  3. Round up to 6.
  4. 6X 0.53 = 3.18.
  5. 3.18 - 2.8 \u003d 0.38m (or 38 cm).
  6. 10: 3.18 = 3.14 (ratio).
  7. 3.14 x 0.38 = 1.19
  8. 10 - 1.19 \u003d 8.81m.
  9. 43: 8.81 = 4.8 (i.e. optimally 5 rolls will be required per room in this example).

Rolls come in different sizes, but these calculation methods are suitable for any wallpaper: you just need to substitute those numbers that reflect the size of the selected wallpaper.

Calculation of the required amount of liquid wallpaper.

If liquid wallpaper is chosen for finishing the room, then the specifics of the calculations change slightly, but you still have to calculate the total area of ​​\u200b\u200bthe working surface.

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

For example, if the working surface area in the room is 30 sq. m., then with an average consumption of liquid wallpaper in one package of 3 sq.m, 10 packages of such wallpaper will be required.

Depending on the experience with liquid wallpaper and the condition of the walls, it is recommended to take 1-3 bags in stock.

Wallpaper is the most popular means of decorating walls in residential areas. With their help, you can make absolutely any design in the room without resorting to excessive financial costs. When choosing wallpaper, consumers face the problem of choosing the right number of rolls. How to calculate the number of wallpapers correctly?

What is needed for the calculation

Usually, the roll label indicates an approximate scheme for calculating the number of wallpapers. To find out the value yourself, you must calculate the following parameters in advance:

  • Wall surface area.
  • Roll width.
  • Roll length.
  • Ceiling height.

The length and width of the wallpaper roll can be seen on the label upon purchase. Knowing the values ​​​​will help to correctly calculate the number of wallpapers per room.

The main types of wallpaper depending on the width

Some 20 years ago, all wallpapers in the countries of the former USSR had standard length and width parameters: 50 cm by 10 m. In the modern world, the repair materials market implies a large number of different types of wallpaper. Let's consider the main ones:

  • 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 paper or vinyl based wallpaper. If their basis is fabric, then the length parameters will be 15 m. This type of wallpaper is optimal for pasting walls with a ceiling height of 300 cm.
  • A roll 60 cm wide. This type of wallpaper was widespread in the 90s. 20th century. However, now they are practically not used. The length value can be from 8 to 10 m.
  • Roll width 74 cm. European type of wallpaper. They are standard length. It is 10 m.
  • Meter rolls. Appeared about 10 years ago. However, they have already gained popularity. Roll widths range from 100-106 cm. Manufacturers produce meter-long wallpapers with different lengths. The standard one is 10 m. They also produce rolls with a length of 12 and 25 m.

Find out the area of ​​the room

Main stages of work:

  1. We draw a floor plan.
  2. We make our own measurements.
  3. We make the necessary calculations.

We draw a floor plan on our own

How to count the number of wallpapers for one room? Before you get started, you need to prepare the following tools:

  • Paper.
  • Ruler.
  • Pencil or pen.

It is necessary to draw a plan of all the rooms in the room. To do this, you need a ruler and a pencil. Absolute precision and scale ratio are not required here. The main thing is to schematically depict the room necessary for the calculation.

After the walls are schematically depicted, the location of the windows and doors in the room should be indicated on the plan. Scale and precision values ​​can also be ignored.

Self measurements

How to calculate the number of wallpapers? To do this, you should find out the values ​​​​of the sides of 1 roll and the values ​​\u200b\u200bof the surface area of ​​\u200b\u200bthe walls of the room. To calculate the last number yourself, you must do the following:

  1. To work, you need a tape measure. With its help it is necessary to measure the length of the walls of the room. To do this, measurements are taken along each wall. The height of the measurements does not matter. It all depends on where it is most convenient to work. You can measure the length along the baseboard, you can in the middle of the wall or just under the ceiling.
  2. In a similar 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 ​​will be the most correct.
  4. We measure the values ​​\u200b\u200bof the height and width of doors and window openings using a tape measure.
  5. Calculate the area of ​​each of the walls. To do this, multiply the length value by the resulting height value. The number found will show the area of ​​\u200b\u200bone wall of the room. From it it is necessary to subtract the value of the opening area (window or door). To calculate its area, you must also find the product of the sides.
  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 wallpapered, the resulting values ​​\u200b\u200bmust be summed up.

Find out the required number of rolls

For the calculation, you will need to know the value of the perimeter of the room. To find it, you need to get the sum of the lengths of all the walls of the room.

The resulting perimeter must be divided by the value of the width of one roll. It is indicated on the wallpaper label. The resulting value will show how many wallpaper sheets will be required to paste over the entire room, excluding window and door openings.

Next, you should calculate how many canvases one wallpaper roll will last. To do this, the value of the length of the roll should be divided by the value of the height of the room. The resulting number will show how many whole strips will come out of one roll.

How to calculate the number of wallpaper rolls for pasting the entire room? To do this, the previously obtained value of the total number of wallpaper sheets should be divided by the specified number of strips from one roll. The resulting value is rounded up to an integer. We have determined the total number of rolls required for one room.

Wallpaper should be purchased after all measurements have been completed. Compliance with these rules will allow you to find out how to correctly calculate the number of wallpapers for a room.

Wallpaper Calculator is designed to calculate the number of rolls when finishing the entire room or certain walls separately. The second calculation option can be useful if it is assumed that the room contains more than 4 walls, or in cases where it is necessary to calculate the wallpaper for specific areas of different sizes.

In addition, the calculation process takes into account the presence of door and window openings, which allows you to optimize the consumption of wallpaper and eliminate overpayment for unnecessary materials. In addition, this is required in order to correctly calculate the area of ​​\u200b\u200bthe walls, which in turn allows us to estimate the amount of glue needed.

In the application, you can familiarize yourself with the normative values ​​\u200b\u200bof the consumption of glue. You can immediately "estimate" how much wallpaper paste is required.

Calculation principle

There are two fundamentally different calculations of wallpaper per room - by area and by turning the roll onto the wall. The disadvantage of the first method is that the wallpaper area is calculated as one continuous roll, i.e. when pasting, the roll may end in the middle of the wall and, accordingly, a seam will appear. The second method implies that if the remaining length of the roll is less than the height of the ceiling, a new roll is taken, and the remains of the old one are used for smaller elements, for example, under a window.

The wallpaper calculator uses last option, since it is the most rational, although it slightly increases consumption.

A little more detail should be given to the calculation method itself. For example, the simplest case is when the wall of the room from top to bottom is a solid surface (1). In fact, we kind of roll out roll after roll along the height of the wall. Another option is when the opening completely (2) or partially (3) overlaps the roll. In the first case, a whole rapport is added to the segment, and in the second, a whole strip is taken, but the pasting area decreases accordingly.

Instruction

For the first option:

  • ceiling height, m;
  • width and length of the room, m;

For the second option:

  • ceiling height, m;
  • wall length, m;
  • number of walls, pcs.

As an additional condition, you can use the "Windows" and "Doors" blocks. With their help, when calculating the wallpaper, the areas that will be occupied by the corresponding structures are taken into account and / or excluded.

The tool calculates wallpapers equally correctly in situations where canvas in whole or in part enters the opening.

Also, if you have other places where wallpaper is not expected, for example, an interior window between the living room and kitchen or a furniture set, allowed use of the fields "Windows", "Doors" and for these purposes.

Then you need to fill in the characteristics related directly to the wallpaper:

  • roll width, cm;
  • roll length, m;
  • rapport (repetition of drawing), cm;
  • margin for leveling, cm;
  • overlay on the side, cm;
  • whether to move the drawing;
  • Cost, rub.

Let's take a look at some of the steps in more detail.

rapport- this is a repeating part of the pattern, or otherwise, a parameter that shows the cyclical repetition of the pattern in height and / or width. The value is indicated directly on the roll and is measured in centimeters. If you have wallpaper without a picture, then enter "0" in the field.

Margin for leveling(cutting)- additional value for each sweep of the web for cutting in case of horizontal unevenness of ceilings / floors. The optimal value is 5-15 cm.

Side overlay- means partial overlapping of one roll with another, the so-called "overlapping" pasting technology.

Move drawing- pattern shift by 0.5 rapport. In fact, it leads to an increase in wallpaper consumption.

Wallpaper glue consumption table

Unfortunately, our online calculator currently only shows the area that will need to be treated with glue, but does not provide actual consumption data. For the convenience of visitors, we have collected reference data of the most popular types of products on the market and combined them into a table so that you can immediately "estimate" how much wallpaper glue you need.
