How many rolls of wallpaper do you need per room. Calculation of wallpaper for a room - we are looking for the optimal solution to the problem. Calculation of the number of wallpapers for standard gluing

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 the overpayment for extra 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 you need wallpaper glue.

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 height ceiling, a new roll is taken, and the remains of the old one are used for more small items, for example, under the 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 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.

Use the convenient website wallpaper calculator and you will no longer have questions - how to calculate the number of wallpapers per room?

Table for calculating wallpaper by room area

In some cases, when calculating wallpaper for a room, it is more convenient for the user to use normative tables to obtain an approximate result. We offer you an option that involves the calculation through the area and height of the room.

Wallpaper with a roll width of 53 cm and a length of 10 m (standard)

Wallpaper with a roll width of 70 cm and a length of 10 m (European)

Wallpaper with a roll width of 106 cm and a length of 10 m (meter)

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.

Door and window openings are not taken into account here, because in any case you need to buy materials with a small margin. Moreover, when gluing, craftsmen can ruin several canvases, picking up best way. Over time, the surface may tear, children may paint on the walls, or pets may spoil it.

• All dimensions are indicated in meters (for example, 52 cm = 0.52 m).
• If the room has a complex shape (not rectangular), you must independently calculate the perimeter of the walls and specify it manually. In this case, specify the length and width of the room as 0.
• Rapport is a step through which the same pattern is repeated. It is usually listed on the packaging. If you don't want to adjust the pattern, enter 0.
• How many meters in a roll of wallpaper? The standard roll length is 10 m. Some natural species are 5.5 m long, and many glass and paintable vinyl wall papers reach a length of 25 m.
• The most popular canvas widths are 53 cm, 70 cm and 106 cm.

How the wallpaper calculation calculator works

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

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

Calculation example

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

P \u003d (5.6 + 3.03) * 2 \u003d 17.26 m.

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

Estimated height = 2.5 + 0.1 = 2.6 m.

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

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

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

25 / 2.6 = 9.6 pieces. We round the result down (remove the trimmings), we get 9 pieces.

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

17 / 9 = 1.9 pieces. As you can see, for a room of 17 sq. m. with ceilings of 2.5 m, 2 rolls of 1.06 * 25 m in size are enough.

However, it is always recommended to buy one additional roll for a spare, because if even one canvas deteriorates, you will have to buy additional materials. Even if you find exactly the same type of ornament, it is not guaranteed that it will be identical, as colors may vary between batches. Therefore, in our case, it is not necessary, but it would be better to take 3 rolls, the rest will then be useful for repairs.

Any repair in the apartment should begin with the preparation of a preliminary estimate to determine the required amount Supplies that will be needed during the finishing works. If the task is to replace the wallpaper in the room, then first of all you need to determine the number of rolls required for pasting it. Correctly performed calculation will allow in the future to avoid unnecessary problems during the repair, as well as save your money.

Today, there are several well-known and available ways calculation of the required number of wallpaper rolls:

• along the perimeter of the room and the number of stripes;
• by the total surface area of ​​the walls required for gluing;
• using online calculators.

Calculation along the perimeter of the room and the number of lanes

This method involves determining the required number of wallpaper strips required for pasting a particular room. For this:

• the length and width of the room are measured, on the basis of which its total perimeter is determined;
• the width of the window and door opening is measured, which is subtracted from the total perimeter;
• the resulting value is divided by the width of the wallpaper rolls with which it is supposed to paste over the room;
• the calculated value is rounded up to an integer value upwards and represents right amount stripes;
• this value is divided by the number of strips that one roll of wallpaper contains, depending on its length;
• the resulting value is also rounded up to an integer value, which is the required number of wallpaper rolls.

Consider this calculation method using a specific example:

Example. It is required to paste over an ordinary room measuring 7.5 m by 3 m, with a ceiling height of 2.5 m, a window opening of 2.1 m by 1.5 m and a door of 0.9 m by 2 m. Wallpaper 53 cm wide will be used for pasting and 10 m long.

To calculate the required number of wallpaper rolls, you need:

1. Determine the total perimeter of the room: (7.5 + 3) * 2 = 21 m.
2. Determine the total width of the window and door opening: 2.1 + 0.9 = 3 m.
3. Subtract from the total perimeter the total width of the openings: 21-3=18 m.
4. Divide the resulting value by the width of the wallpaper roll: 18 / 0.53 \u003d 33.9 and round the result to an integer value - you get 34 strips required for pasting the room.
5. Calculate the number of wallpaper strips in one roll, for which you need to divide the length of the roll by the height of the stream: 10/2.5=4.
6. Divide the required number of wallpaper strips by the number of strips in one roll: 34/4 = 8.5 and round this figure up to a whole value - it turns out 9.

Thus, for pasting this room, 9 rolls of wallpaper will be required. It should be borne in mind that this method does not take into account the surface of the walls above and below the window and door openings, so it is advisable to purchase an additional roll.

Calculation by the area of ​​the pasted surface of the walls

This method is considered more accurate and economical, especially for rooms with a large area. It is based on determining the total surface area of ​​the walls of the room to be wallpapered.

For this:

• calculated total area walls by measuring the perimeter of the room and multiplying it by the height of the ceiling;
• the total area of ​​window and door openings is determined;
• the resulting value is subtracted from the total area of ​​\u200b\u200bthe walls, resulting in a value equal to the surface area of ​​\u200b\u200ball the walls that need to be wallpapered;
• the area of ​​the wallpaper in one roll is calculated by multiplying the width of the roll by its length;
• in conclusion, the total area of ​​​​walls for pasting is divided by the area of ​​\u200b\u200bwallpaper in one roll;
• the resulting value, rounded up to an integer, will be the required number of rolls for pasting the room.

Using an online calculator

If there is no desire or opportunity to carry out calculations yourself, you can use a special online calculator. Today, there are many sites on the Internet that allow you to use the services of such an online calculator for free.

To carry out the calculation, you must first measure the following quantities:

• room length;
• room width;
• ceiling height;
• wallpaper roll width;
• wallpaper roll length

The obtained values ​​must be entered in the appropriate fields on the online calculator's web page and the finished result will be obtained.

For example, let's use the online calculator available on the site, using the same initial data as for the first two examples. We enter the available values ​​in the appropriate fields and we get the same result - 9 rolls of wallpaper required for pasting this room.

Have you finally decided to re-paste the wallpaper in your room? It's time for old wallpaper to retire and you are wondering how to calculate the number, how many rolls do you need? Answer next...
The most common wallpaper size is a 10 meter roll half a meter wide 10 m x 0.53 m. It is enough for pasting about 5 square meters walls and or ceiling. There are wallpaper rolls with a length of 15*0.53 m, 10*1.06 and 25*1.06 m.

Wallpaper calculation

1. first measure the perimeter of your room. Do not forget to remove from the result the perimeter of the surface that is not subject to pasting, these are windows and doors, (6.5 + 4) x 2 \u003d 21 m.

1. And then, divide the resulting number by the width of the roll (usually 50 cm). The resulting figure shows the number of stripes, 21 / 0.53 = 40 stripes.

1. Measure the height of your walls (don't forget to add a little margin for later trimming, say 5 cm) 2.50 + 0.05 = 2.55 m

1. Then count the number of strips per roll, 10/2.55 = 3

1. Now divide the number of strips by the number of strips per roll to determine the number of rolls, 40/3=14 rolls

Special cases

If there are ledges or recesses in the niches of the doors, then add 1-2 additional rolls of wallpaper.

If you are using wallpaper with patterns, you need to add a margin to the height calculation to fit the pattern: 2.50 + 0.05 (cut off excess) + 0.30 (fit the pattern) \u003d 2.95 m.

Ceiling calculation

The ceiling is the same. Recently, however, pasting the ceiling with wallpaper does not look elegant. Today, a lot of embossed ceiling tiles have appeared that look more organic and aesthetically pleasing.

Don't forget to buy one or two extra rolls of wallpaper. Especially if the connections go in a checkerboard pattern, just for your mistakes, the offset is higher and lower.
- Be sure to pay attention to the wallpaper series number. If the series are different, then the difference in color and brightness will be noticeable after pasting.

How to save?

If you made a mistake in the calculation, and it is no longer possible to purchase such wallpapers, then you can purchase similar ones. And decorate some of the walls with other wallpaper. In fact, this option looks very modern and non-standard. In this case, the view zones will change, that is, from different parts rooms, her appearance will be different, which will also have a pleasant effect on her perception.
Option with no pasting behind the sofa and wardrobe for an amateur.

calculator to help you

If you are not sure about the calculations, you can also use the ready-made table to determine the number of wallpaper rolls:

Use the following table to calculate the wallpaper:

Roll size 0.53 / 10.05 m = 5.33 m2

Roll size 0.53 / 15m = 7.95m2

Roll size 1.06m /10.05m = 10.65 m2

Roll size 1.06 / 25m = 26.50m2

During the repair, the decoration of the premises becomes the main priority, in fact, everything is started for this, but before purchasing materials, you need an accurate calculation of wallpaper for the room. How it is done - we will consider further.

Where does the calculation of wallpaper for a room begin?

What is most interesting, there is no need to immediately grab the rolls and find out how many running and square meters of paper, non-woven, vinyl or fiberglass are in them. To begin with, we find out the area of ​​\u200b\u200bthe room that we will paste over. Of course, we leave the floors without attention, we are more interested in the walls and, possibly, the ceiling, if you want to decorate it for the company. Before calculating the number of wallpapers per room, we take a tape measure and measure the perimeter of the room, it is advisable to do this 2 times, along the plinth and under the very ceiling. A slight curvature of the walls can give a significant discrepancy in the results, but then you will know what error will need to be added to the calculations or, conversely, subtracted from them.

Let's say, below, near the floor, the perimeter turned out to be 8 meters, 2 for each wall, a perfect square. But at the top, the corresponding indicators are somewhat smaller, all sides of the above geometric figure 5 centimeters shorter. It turns out that the room in volume is not a cube, but a kind of prism or truncated pyramid, except that the slope of the vertical planes is very slight. Nevertheless, it is already possible to imagine how in the corners applied at the top they will deviate downward from the general pattern. Conclusion? It will be necessary to glue across, that is, by applying cuts of material horizontally. As you can see, having learned only the perimeter and geometry of the room, at the same time we found out the most effective method finishes.

Further is quite simple. We know the height and length of the wall, we substitute the values ​​\u200b\u200bin the formula S = a. b, Where a And b- the sides of the rectangle, which (sometimes rather conditionally) are the wall or ceiling. Then we measure windows and doors, substitute new results into the same formula and determine the square of openings that do not require finishing at all. The result obtained is subtracted from the area of ​​​​the walls, and here we have the number from which the calculation of wallpaper per room always begins, indicating how many square meters are to be pasted.

How to calculate wallpaper based on rapport

So, the whole room has been measured, the data has been recorded, it remains to determine how much material will be needed for the upcoming work. If you haven't had time to peel old finish, try to correlate the width of the cuts pasted once with the wallpaper that is sold today in the store. The sizes may well coincide, and then it remains only to count the number of strips to find out how many panels will go to the room. Knowing the footage of each individual roll (usually it is written on reverse side or on the package), it is not difficult to calculate how many pieces you need to buy.

However, it may well turn out that the rapport does not match between old and new wallpapers, or, in other words, a repeating pattern printed on the surface with a certain step. Firstly, the difference may be in the size of the pattern, and secondly, it is quite rare for different series to have the same distance between images. If the store you went to for materials is branded, and there is a professional behind the counter, you can ask him about the rapport step, however, if you did not receive an answer to this question, you need to figure out how to calculate the wallpaper yourself. Typically, the distance between the centers of the impressions corresponds to 52-53 centimeters. Ideally, the height of the wall should be divisible by this number without a trace or with small decimals, otherwise waste will appear during the work.

Let's take a situation as an example. Let's say the height of the wall is 3 meters, let's see how many rapports fit from floor to ceiling. The formula will look like this n = H/j, Where n- the number of drawings, H is the height of the room, and j- step between prints. Substituting the data we have, we get 300/52 = 5.76, which is more convenient to round up to 6 rapports. However, 6 . 52 = 312, that is, in any case, at least 12 centimeters will be cut off from the wallpaper strip. Why cut? The thing is that in order to match the pattern on adjacent strips, you need to shift them relative to each other, and waste is inevitable. Therefore, if the pattern allows (not oriented strictly vertically), it is better to glue strips with a large step between images horizontally.

Usually, when the strips are shifted, half a step is cut off between rapports, therefore, the greater the distance separating the prints, the wider the piece sent to waste.

How to calculate wallpaper rolls, knowing the area of ​​\u200b\u200bthe walls

Having gathered to paste over the room, some owners quickly make calculations of the upcoming front of work on the length, width and height of the room, after which they go to the store with peace of mind. And then it turns out that the wallpaper is not enough. The reason for this is often an incorrect calculation, with a room height of 3 meters, and a width and length of 2 and 3, respectively, having the form of 3. 2. 3 = 18, but what? That's right, cubic meters, that is, this is the volume of the room, which we do not need. And if we take the perimeter as a basis and multiply it by the height, the same numbers will give a different result: (2. (3 + 2)) . 3 = 30. Do you see the difference? Not knowing how to calculate wallpaper rolls, you can buy them not for 30 real square meters (albeit without taking into account window and doorways), but for 18 imaginary ones, that is, 12 squares will be missing, and this is at least 2 rolls.

By the way, how to calculate how many packages will be needed without knowing how many meters in a rolled strip of paper, vinyl, non-woven or bamboo fiber? Let's find out what the options are. If you have an apartment 3 meters high, and you are going entirely, from floor to ceiling, it is most convenient, of course, to buy rolls of 18 or 12 meters. However, there are also shorter, designed for low-ceiling apartments - 10 and 7 running meters. It is better to take the first of them, if you take into account the plinth and the border along the upper edge of the wall, then the cut will not be 2.64 ( standard height panel houses), and 2.5 meters. The second type of rolls is very convenient for Khrushchev, in which the distance from floor to ceiling is only 2.48 meters, in this case it will be enough to divide the strip into cuts of 2.3.

Now let's move on to how to calculate how much wallpaper is needed for pasting a room. When buying, it is more convenient to count in rolls, therefore, knowing the area of ​​\u200b\u200bthe walls (and the ceiling, if the finish is provided for it), it will not be difficult for you to perform the necessary calculations right in the store. Since the dimensions of the wallpaper are written directly on the roll, you can immediately determine the area of ​​\u200b\u200bone panel. Next, we divide the quadrature of the walls to be glued by the result obtained (minus window and door openings) and get the required number of rolls. Consider this in the table using the example of a ten-meter strip, the width of which is half a meter.

Roll size: 10.05 m × 0.53 m = 5.3 m 2 .

Depending on the standard sizes of the wallpaper, the data laid out in the table will change, so only the principle of calculation should be taken as a basis.
