How to calculate the area of \u200b\u200bwallpapering. Calculation of wallpaper for a 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 quantity, how many rolls do you need? The answer is further ...
The most common size of wallpaper is a 10 meter roll with a width of half a meter 10 mx 0.53 m. It is enough to cover about 5 square meters of walls and ceilings. There are rolls of wallpaper with lengths 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 roll width (usually 50 cm). The resulting figure shows the number of stripes, 21 / 0.53 \u003d 40 stripes.

1. Measure the height of your walls (remember to add a little margin for later trimming, say 5cm) 2.50 + 0.05 \u003d 2.55m

1. Then count the number of strips per roll, 10 / 2.55 \u003d 3

1. Now divide the number of strips by the number of strips per roll to determine the number of rolls, 40/3 \u003d 14 rolls

Special cases

If there are ledges or indentations in the door niches, 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 (excess cut) + 0.30 (pattern fit) \u003d 2.95 m.

Ceiling calculation

With the ceiling, everything is the same. However, recently, wallpapering the ceiling does not look elegant. Today, there are many relief ceiling slabs that look more organic and aesthetically pleasing.

Don't forget to buy one or two additional rolls of wallpaper. Especially if the connections are staggered, the same for their mistakes, the shift is higher and lower.
- Be sure to pay attention to the number of the wallpaper series. If the series is different, the difference in color and brightness will be noticeable after pasting.

How to save money?

If you made a mistake in the calculation, and it is no longer possible to buy 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 of the room, its appearance will be different, which will also pleasantly affect its 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 a ready-made table to determine the number of wallpaper rolls:

Use the following table for calculating wallpaper:

Roll size 0.53 / 10.05 m \u003d 5.33 m2

Roll size 0.53 / 15m \u003d 7.95m2

Roll size 1.06m / 10.05m \u003d 10.65 m2

Roll size 1.06 / 25m \u003d 26.50m2

Before pasting the walls, you need to calculate the number of wallpapers for the room Wallpaper is one of the most popular materials for decorating an apartment. They are easy to use and give the walls a noble and neat appearance. However, for many, the most important difficulty in using this material is calculating the required number of rolls. And this is not surprising, because there are a huge number of nuances that are important to know in order to calculate the footage of the wallpaper correctly.

Wallpaper calculation: step by step instructions

Before you go to the store for wallpaper, you need to find out exactly how many meters of this material you need to decorate your apartment. After all, if you purchase less rolls than you need, then in order to glue the room you will have to find the same material, which is sometimes very difficult to do. More wallpaper leads to unnecessary costs.

1. The first step is to measure the length of two adjacent walls. The resulting size is multiplied by two.
2. Next, you need to measure the height of the wall. This is necessary in order to find out how many sheets can be obtained from a roll.
3. The length of the wallpaper roll is now divided by the height of the wall. The resulting number of canvases is multiplied by the width of the wallpaper. This is the size of the area that can be covered with one roll.
4. To find out the number of rolls that you need to purchase, the perimeter of the room in centimeters is divided by the area that can be covered with one roll. The resulting figure is rounded up.

Thus, the formula for calculating the number of rolls looks like this: P (perimeter of the room) / (L (length of wallpaper) / C (height) * E (width of wallpaper)); R: L: S * E \u003d number of rolls.

To find out the number of wallpapers you need, it is not necessary to make calculations yourself. You can use an online calculator. There is also a table showing the standard footage of wallpaper for standard apartments.

Quick calculation of wallpaper for the area of \u200b\u200bthe room

Calculating the area around the perimeter is a fairly common method, but there is another equally fast option. Most professional painters use it.

For calculations, we need to find out the area of \u200b\u200bthe room. To do this, add the width of the wall to the width of the adjacent wall, and then multiply the resulting sum by two. We figured out the perimeter, which needs to be multiplied by the height of the walls. Thus, we figured out the area of \u200b\u200bthe room.

When we know the area of \u200b\u200bthe room, we need to figure out the area that can be pasted over with one roll of wallpaper. To do this, we multiply its width by its length. The resulting number is rounded down. To find out these parameters, just look at the packaging, the manufacturer must indicate there all the information about his product.

A quick calculation of wallpaper by the area of \u200b\u200bthe room can be done in two ways

Now the resulting areas can be divided into each other. That is, we are dividing the size of the room by the size of the wallpaper. The resulting number must be rounded up. This value will be the required number of rolls.

The formula for calculating wallpaper by area looks something like this: S rooms (A + B) (wall width) X 2 X C (wall height): S wallpaper (K \u200b\u200b(wallpaper width) X T (wallpaper length).

Each wallpaper material weighs differently, so it is impossible to know the amount of wallpaper required by weight. If you do not want to do the calculations yourself, you can refer to special tables and calculators.

How to calculate the number of wallpaper adjusted for the pattern

The number of rolls that will be needed for one room directly depends on how the wallpaper is decorated. It may seem strange, however, from the size and complexity of the pattern, a lot of wallpaper waste can be generated.

To count the number of rolls, pay attention to the marks on the package

What are the types of wallpaper combination:

1. No alignment is required. This designation is an arrow pointing to a circle. This option is the simplest. It is suitable for wallpaper with a small, unexpressed pattern or without it at all. The consumption of such wallpaper exactly corresponds to the formula.
2. The arrows directed one up, the other down, indicate that wallpaper canvases must be turned upside down through one. This method also does not require additional material costs, however, you need to be extremely careful when gluing.
3. A more difficult option is when the drawing requires mandatory matching. This method is quite costly, and usually requires removing from some strips of wallpaper a piece close to the size of one report. In this case, an icon appears on the packaging with arrows located parallel to each other.
4. The variant with a displacement pattern is the most difficult to glue, and requires the greatest consumption of wallpaper. With this option, from each new canvas, you will have to cut off a strip of wallpaper equal to about half of the report. Such gluing is characteristic of wallpaper with a large pattern located diagonally. In this pictogram, the arrows look at each other, but are located at different levels.

It is very easy to make a mistake with the penultimate and last type of wallpaper. You can either count the number incorrectly, or inaccurately combine the drawing, and then the room will look strange and messy.

When choosing such wallpaper, be prepared for the fact that you will have to purchase at least two more rolls. The advantage of patterned wallpapers is that they look very eccentric and hide all the unevenness of the walls.

How much wallpaper do you need in a room with a non-standard layout

When measuring the parameters of a room, it is imperative to take into account its layout. If this is not done, then in the end you may simply not have enough rolls of material.

Particular attention should be paid to niches, ledges and columns. They take up a fairly large amount of material. The niche area is calculated separately and then summed up with the main dimensions.

In a room with a non-standard layout, special attention should be paid to niches, ledges and columns

If you plan to use built-in wardrobes in the interior, then you do not need to wallpaper the places where they will stand. However, in this case, you deprive yourself of the possibility of rearrangement without updating the repair.

It is also worth considering the characteristic features of the design of your room. If you decide to use several types of wallpaper in one room, then their footage must be calculated separately. For example, the area of \u200b\u200bone wall is calculated separately, and the other three separately.

Calculation of materials for renovation is an important point in finishing an apartment. There are a huge number of special calculators and tables, but do not forget about the good old formulas that have helped builders more than once at the right time.

Technology: how to calculate wallpaper for a room (video)

When planning the design of an apartment, remember that the more types of wallpaper are present in one room, the more difficult it will be to figure out the required number of rolls. Of course, this fact is not a reason to abandon your ventures. If you are not sure that you will be able to correctly calculate the amount of wallpaper, then you can contact the professionals or consult a good seller, a consultant at a hardware store.

So that you do not make a mistake in calculating the wallpaper that is needed for repairs, you need to correctly calculate their volume. Well, if there are extra ones, you can simply use them later.

But if a roll or a few centimeters is not enough, in this case you will have to work hard. And then, it is not a fact that you will find exactly the same batch. The canvases may differ in the tone of the pattern, and this is not entirely good.

Anyone can decide on the required volume, even without a special education in construction or experience in construction.

Moreover, if there is no pattern on the wallpaper. You just need to know how to make the correct calculation. And here the following sequence is required:

• First of all, you need to measure the length and height of the walls.
• Now you need to calculate their total perimeter. To do this, add the lengths of two adjacent walls and multiply by 2. Suppose our walls are 6 and 5 meters, which means that the perimeter is 22, i.e. (6 + 5) x 2 \u003d 22 m.The standard size of the roll is 53 cm wide and 10 m long.
• The wallpaper is easier to calculate by the number of strips required. For example, the height of the wall is 2.5 m, therefore, 4 strips will turn out from the roll. And the total width will be equal to 212 m, i.e. 4 x 53 \u003d 212 cm. Now we perform the arithmetic operation of dividing 2200 cm: 212 cm \u003d 10.38 rolls. We round it up, and it turns out 11 pieces.
• If you need to paste over the ceiling with wallpaper, then the calculation must be made separately.

If you bought wallpaper with a pattern, then the calculation described above will not be able to take into account the rapport, this is the distance between the elements of the pattern.

Such canvases are glued strictly according to the pattern, without violating the integrity of the general perception. Usually the rapport is indicated on the packaging, and the larger it is, the higher the wallpaper consumption will be.

But if the cash costs do not scare you, then you need to observe some nuances and proceed as follows:

1. Measure the perimeter of the walls and the height of the ceiling with a tape measure. Measure solid walls and the distance under and above windows (doors) separately.
2. Know the dimensions of the roll. For example, its width is 0.53 m, the length is 10.5 m, the rapport is 0.2-0.4 m. The ceilings are 2.6 m. Therefore, one roll will produce 3 sheets of 3 m long \u003d 2.6 + 0.4.
3. If you measured the walls with sheets, then you need to divide the number of sheets on the walls by the number of sheets in a roll. And if meters were used in the calculations, then one roll will be equal to 1.59 m. \u003d 0.53 x 3. These figures are divided by the footage of the perimeter of the walls.
4. The pieces you have left might work for sections of walls above a door or above a window.

The main feature of liquid wallpaper is that it has no seams. And this feature gives the room a certain completeness.

This versatile finishing material is pleasant to the touch, safe for humans and allows designers to create original and unique projects.

To glue liquid wallpaper in your apartment, you need to determine the number of packages that are necessary for the production of work.

To make a correct calculation, it is necessary to divide the wall area by the consumption of one package. This information is listed on each package. Usually one package is enough for a surface of 3-5 m 2. Let's say the area of \u200b\u200bthe walls of the room is 40 m 2, and the average consumption of one package is 4 m 2. By dividing 40: 4, the required consumption was obtained - 10 packages.

But when purchasing liquid wallpaper, be sure to buy their quantity with a margin of 1 - 3 packages. Liquid wallpaper can be applied on an uneven surface that has small defects. This means that the consumption of the material used may increase, so take care of this in advance.

The question - how to calculate how much wallpaper is needed per room - is not an easy one, because no one wants to overpay for the leftovers or, conversely, buy several rolls. And if the desired colors are not left in the store, then the problem is - where to find them now? In order not to complicate your life, before buying a wall covering, check out how to calculate the required amount of wallpaper.

Advice! If before buying new wallpaper you have not yet removed the old ones from the walls, you can count how many sheets of old ones are pasted on the wall. But when gluing a new coating, keep in mind that the width of the new ones must be equal to the width of the old ones, otherwise the advice does not work.

Preliminary measurements of the room

Measurement accuracy is the basis of any calculation. For all measurements and in order to calculate the amount of material per room correctly, you will need:

• construction tape or measuring tape;
• calculator;
• paper and pen for recording the results.

First, measure the length and width of the room, as well as the height of the ceiling. You should not take into account the level of the walls, and the sizes of windows and doors must be measured separately - these data will be useful in calculations. If the design provides for a wide ceiling molding, box or false ceilings, their width should be subtracted.

Measure carefully:

• protrusions;
• niches;
• space above doors and windows.

Advice! If the room has an uneven ceiling, it is recommended to measure the wall in the highest place.

Calculation of wallpaper around the perimeter of the room

One way to calculate the number of wallpaper pieces is to calculate around the perimeter of the walls of the space. In a similar way, you can calculate how much wallpaper is needed to finish the ceiling.

Attention! For those who have forgotten the formula for calculating the perimeter: you need to add the length of one wall to the length of the adjacent wall, and multiply the result by two. Use a calculator to avoid mistakes.

The days when all wallpapers were standard width are over. Modern manufacturers offer decorative coating in the following widths:

When calculating, consider whether there is a pattern on the wallpaper or not. Wallpaper with a report (an element of the pattern that is repeated on the wallpaper) requires a margin for selection. If you chose with a large pattern, when calculating, you will have to add up to 0.7 m for selection for each sheet. Before starting the calculations, measure how much the report length "takes" in your case. Plain coverings without a pattern do not require any stock.

Important! If the design of the room provides for several types of canvases, first think over the gluing scheme, and only then calculate the quantity.

Let's get down to the calculations. It is necessary:

Attention! In order not to be mistaken in the lower side in the calculations, the numbers should be rounded up to the whole value, and in the larger direction.

Calculation by the area of \u200b\u200bthe room

The above method has one drawback - the presence of windows and doors in the room is not taken into account, so you will still have extra materials. An alternative way is to calculate the area of \u200b\u200bthe walls. This requires:

1. Calculate the total area - multiply the length and height of the wall.
2. Calculate the area to be pasted over. First, you need to calculate the area of \u200b\u200bwindow and door openings (multiplying their height and width). Next, subtract the total area of \u200b\u200bwindows and doors from the total area of \u200b\u200bthe room (calculated in paragraph 1).
3. Count the number of rolls. Standard wallpaper 0.53x10 m can be pasted over 5 square meters.
4. The final calculation of the number of rolls is the area of \u200b\u200bpasting (figure from point 2) divided by the area that can be glued with one roll (for example, as in point 3).

Important! If you have chosen non-standard, for example, one-meter wallpaper, the size of the surface that can be glued with one roll is easy to find out. To do this, multiply the width and length of the roll or carefully study the label, it may contain this information, which will save you from unnecessary manipulation with the calculation.

How to check your calculations

There are ready-made tables in which the number of standard rolls for rooms with typical sizes has already been calculated. If you counted along the perimeter, check the resulting value:

• pay attention to the series. The numbers on all rolls must be the same, otherwise there may be a difference in color and brightness;
• the material may be defective, so it is worth expanding and checking all the rolls after purchase;
• even in wallpaper with a small pattern, there may be a report that is invisible at first glance;
• you can reduce material consumption if you cut the strips not from one roll, but from several simultaneously;
• the walls above the door and window openings are recommended to be glued with leftovers and scraps, but the image on the sides must necessarily match;
• glue the inner corners, you need to start with a new piece;
• glue the outer corner, overlap the wallpaper, or simply wrap the corner;
• sometimes to align the corner, a thin strip is needed, the length of which is a whole sheet, take this fact into account when calculating the consumption of wallpaper.

Sooner or later, a moment comes to every house when the need for another repair arises. Households with horror represent all the inconveniences that will have to be experienced during it. It is comforting to think that the comfort and coziness of the renovated apartment will be compensation for the spent nerves.

Starting repairs, first of all, it is necessary to draw up a work plan taking into account the financial capabilities and wishes of all family members. Then proceed with the selection of materials. In our time, this is not an easy matter, because you need to optimize the ratio of quality and price. The most difficult to choose wallpaper, because in addition to technological qualities, it is also important to take into account their correspondence in color and texture to the design solution of the apartment as a whole. The effectiveness of the entire repair depends on the correct choice of wallpaper, because it is this type of building material that affects the interior appearance of the apartment. It is also extremely important to correctly calculate how many wallpaper rolls are needed so that they are enough for the entire wall area, but not too much remains.

How much wallpaper to buy?

There are several methods for calculating the number of rolls, depending on the type of wallpaper and their size. In any case, the calculations must begin with measuring the area of \u200b\u200bthe glued surface. It does not include the area of \u200b\u200bwindows and doors. Knowing the height of the wall and the footage of one roll, you can calculate how many canvases are obtained from it. If the height of the walls is 230-250 cm, then in one standard roll four canvases with a total width of 2 12 centimeters (4 rolls x 53 cm) are laid. That is, for every 2 meters of the perimeter of the room area, a roll of wallpaper is needed. If you divide the perimeter of the room by 2 meters, you get the required number of rolls.

The calculation is quite simple, but at the same time it is still necessary to take into account such a technological indicator of wallpaper as rapport or the number of areas with a large pattern on one panel. This number on all segments must be the same for the drawing to match. Therefore, wallpaper with a large pattern is bought with a margin.

Experts calculated tables to determine the required number of paper rolls of standard sizes, depending on the perimeter or area of \u200b\u200bthe room.

Calculation of the need for wallpaper rolls measuring 10.05 x 0.52, taking into account the perimeter of the room (including the area of \u200b\u200bwindows and doors)

You can also use wallpaper calculator, which is presented below. Just indicate the perimeter of the room and the height of the walls, as well as the length and width of the rolls and get how much wallpaper you need to buy to paste over a room or corridor.
