How to calculate how much wallpaper you need for a room. Universal ways to calculate wallpaper in rooms of various configurations using formulas and a calculator. Walls with complex configurations

Before you paste over the walls, you need to calculate the amount of wallpaper for the roomWallpaper 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 main difficulty in using this material is the calculation of 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 wallpaper store, you need to find out exactly how many meters of this material you need to finish the apartment. After all, if you purchase fewer 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 unjustified costs.

1. First of all, you need 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. Now the length of the wallpaper in the roll is divided by the height of the wall. The resulting number of canvases is multiplied by the width of the wallpaper. This is 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 (room perimeter) / (L (wallpaper length) / C (height) * E (wallpaper width)); R:L:S*E = number of rolls.

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

Quick calculation of wallpaper by room area

Calculating the area around the perimeter is a fairly common method, but there is another equally fast option. It is used by most professional painters.

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 amount by two. We figured out the perimeter, which must be multiplied by the height of the walls. Thus, we found out the area of ​​\u200b\u200bthe room.

When we know the area of ​​​​the room, we need to find 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 divide the dimensions of the room by the dimensions 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 ​​(wallpaper width) X T (wallpaper length).

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

How to calculate the number of wallpapers adjusted for the pattern

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

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

What are the wallpapers according to the type of combination:

1. Pattern matching is not required. This designation is an arrow pointing to a circle. This option is the easiest. 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 pointing one up and the other down indicate that the wallpaper must be turned upside down through one. This method also does not require additional material costs, however, when gluing, you need to be extremely careful.
3. A more complex option is when the drawing requires mandatory matching. This method is quite costly and usually requires the removal of a piece close to the size of one report from some strips of wallpaper. In this case, an icon appears on the package with arrows located at the ends parallel to each other.
4. The variant with a pattern shift is the heaviest in gluing, and requires the highest consumption of wallpaper. With this option, from each new canvas, you will have to cut off a strip of wallpaper equal to about half the report. Such gluing is characteristic of wallpaper with a large pattern located diagonally. In this icon, 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 incorrectly count the number, or inaccurately combine the pattern, and then the room will look strange and sloppy.

When choosing such wallpaper, be prepared for the fact that you will have to purchase at least two rolls more. The advantage of wallpaper with a pattern is that it looks very eccentric and hides 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 a fairly large amount of material. The niche area is calculated separately, and then added to 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 can not wallpaper the places where they will stand. However, in this case, you deprive yourself of the opportunity to reshuffle 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 separately for the other three.

The calculation of materials for repairs is an important point in the decoration of the 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 find out the required number of rolls. Of course, this fact is not a reason to abandon their ideas. If you are not sure that you can correctly calculate the amount of wallpaper, you can turn to professionals or consult with a good sales assistant at a hardware store.

The desire to make repairs and update the appearance of the walls always begins with the choice of material. In the vast majority of cases, this is wallpaper. However, the most common problem is not to decide on their color and texture, but not to make a mistake with the number of rolls. Therefore, it is important to know how to calculate the wallpaper for a room so that you do not have to buy more material or stock up extra, complaining about wasted finances.

The calculation of the number of wallpapers begins with the choice of the material itself for pasting a room or apartment. Even if the desired color and type of wallpaper are approximately known, there are nuances that are:

• in wallpaper pattern;
• in roll width;
• in a roll.

All these factors directly affect the amount of purchased material, costs and the final result.

The information that will be required is contained in the roll label. The manufacturer must indicate the running meters and width. The width of the wallpaper can be as follows: 0.52 m, 0.53 m, 0.7 m, 0.75 m, 0.9 m, 1 m, 1.02 m, 1.06 m. There are canvases that have a larger width , most often these are stylistic prints (wallpaper). The length of the roll can also vary, but usually this value is 10.05 m, although there are options for 5.5 and 25 meters.

The pattern on the wallpaper plays an important role in the process of pasting the walls, it depends on how much the cutting of the roll will shift so that the finished wall looks solid and no joints are visible.

All wallpapers are made with the repetition of a certain pattern at regular intervals - rapport. The higher the repeat, the more centimeters from each roll will be cut to fit. Manufacturers indicate these parameters directly on the packaging, using special markings for the offset and joints of the panels.

Rapport is not taken into account when buying plain wallpaper with an abstract small pattern or stripes. In all other cases, it will have to be combined in a horizontal plane so that each cut starts from the same element. With rapport with butt-matching, the “superfluous” may turn out to be almost the entire height of the repeating pattern.

It is worth considering another option, when ornate patterns that look great on the wall, when glued, cause excessive consumption of linear meters of the roll. They dock with the greatest displacement. This value can be found by marking and a preliminary estimate of how much material will have to be cut, whether the appearance is worth the estimated financial costs.

Before you start calculating the number of wallpapers per room, you must first evaluate the range offered, focusing on several options. You should carefully consider the marking and remember or write down the data. This will help in further calculations.

How to calculate wallpaper for a room: options, formulas, features

• along the perimeter of the walls and the number of cut strips;
• by the area of ​​the walls and all pasted surfaces;
• using online applications and wallpaper calculator services.

Each of these methods has its own calculation errors, but using them is much more efficient than buying wallpaper without any clarification at all. From improvised means it will be necessary to prepare a tape measure for measurements, paper and a pen for notes and a calculator. Calculating the number of wallpapers per room is simple, outstanding mathematical abilities are not needed here, the main thing is to understand the principle and follow it.

Important! All measurements should be performed only with a tape measure. Approximate data and large tolerances will not lead to accurate calculations.

How to calculate the number of wallpapers per room around its perimeter

The perimeter is the sum of the lengths of all sides of the polygon. In this case, the polygon is the room in which the repair will be carried out. Take a tape measure and measure the lengths of all walls from corner to corner, excluding baseboards and frieze. If the room is made with a bay window, each of its walls must also be measured. Do not be too lazy to take measurements of all walls, because. it may turn out that surfaces that are visually parallel are not exactly the same length in reality.

• P total = length 1 + length 2 + ... + length N,

where N is the number of walls in the room.

The next step is to measure the height of the room from floor to ceiling. To do this, again you need to use a tape measure.

Helpful advice! Ceiling heights can vary within the same room by several centimeters. Therefore, you should take several measurements and choose the largest value.

When the height of the walls is known, you can find out the length of one cut of the wallpaper. In this case, you will need the marking data for the rolls selected earlier in the store:

• canvas length \u003d room height + rapport height + offset value + allowances of 5 cm for the top and bottom for bleed

Now again you need to turn to the markings to find out the length of each roll, because the next step is to calculate the number of cuts of cloths in one roll:

• number of cuts per roll = length of 1st roll / length of 1st blade

On the other hand, if the width of the new wallpaper matches the width of the old ones that the room is pasted over, you can calculate the number of canvases needed directly along the walls.

How to calculate wallpaper using online services

The Internet helps in solving many issues, so if you do not want to do the calculations manually, you can calculate the number of wallpapers online. Various types of counting programs are published on specialized sites. It is recommended to choose those where you need to specify the largest number of room parameters and characteristics of the selected material.

The online calculator builds the wallpaper calculation based on the data that is loaded into it for processing. Wall parameters are required: length and height. If the calculator is of high quality, then it will contain columns for filling in the dimensions of door and window openings, as well as taking into account the offset of the pattern.

Important! Pay attention to the units of measurement for all fields to be filled in the online calculator form. It is permissible to calculate the wallpaper for the room in meters or centimeters. For one form, only the same units of measure are used.

All that is required to get the result is to correctly fill in all the fields and click the count button. The program will instantly carry out the calculation. Using the online calculator, you can calculate the wallpaper directly in the store, so it's easier to navigate the price range of choice.

A way to calculate wallpaper for walls, adjusted for a design decision

Inspired by design solutions, you can paste in one room with a combination of several types of wallpaper. It will be bold and extraordinary if you choose the right combination. In this case, you can calculate the number of wallpapers in any of the above ways, only you need to take into account each type of material separately.

For example, an insert can occupy the entire area of ​​one of the walls. Then the number of basic wallpapers for 3 walls is determined, plus it is separately learned how many rolls will be needed to paste the insert. Difficulty can arise if the selected combination of materials has a different roll width, so be careful about the markings. Measurements should be taken especially carefully if a 3D print or photo wallpaper is used for insertion.

Another option: the decor does not occupy the entire wall, but only part of it, and there is a space filled with the main wallpaper on top, on the sides and, possibly, below (the organization of the panel). In this case, the decorated insert is taken as an additional wall opening. You can calculate the wallpaper for the room both with an online calculator and manually. The calculation of material consumption for decor is carried out separately in any way.

If it was planned to paste over the wall with the organization of panels and edging with a border, then for the wallpaper of the top and bottom (panels), calculations are made separately in a convenient way, taking into account the characteristics of the selected material.

Down with the calculator: how to calculate wallpaper for a room using tables

If it is difficult to calculate using simple but numerous formulas and a calculator, wallpaper for walls can be calculated in a different way. For this, reference auxiliary tables are used, compiled taking into account the width and length of the rolls, as well as the geometric dimensions of the premises. The values ​​indicated in them can serve as a guideline for the purchase of material for repairs, as well as verification of independently performed mathematical calculations along the perimeter and area of ​​\u200b\u200bthe walls.

The tables were compiled without taking into account the rapport of the pattern or its displacement, so the desired values ​​\u200b\u200bmust be corrected for the height of the ceilings, adding additional data to the features of the pattern to the measured values ​​of the room. Thus, the measured ceiling height will be greater by the repeat height plus the offset height. To be scrupulously accurate, then it is worth adding 5 cm allowances for the curvature of the walls for the bottom and top. According to the final value, you should be guided in choosing the number of rolls according to the table.

Important! In the tables, the floor area is taken as the calculated one, and not the total area of ​​\u200b\u200bthe walls, as in mathematical calculations.

An example of a mathematical calculation of the required number of wallpapers for a room

To make it clear how the calculation methods described in the article work, let's calculate the amount of material using a specific example.

Suppose you need to paste over a room where there is one window and a door. Initially, we carry out measurements in the room. For the selected room example, we get:

• room length - 7.5 m;
• room width - 3 m;
• ceiling height - 2.6 m;
• window dimensions - 2.1x1.5 m;
• door dimensions - 0.9x2.0 m.

Let us assume that wallpaper with a large pattern was previously selected for pasting: rapport height - 0.35 m and offset - 0.25 m. Roll dimensions: width - 0.53 m, length - 10.05 m. We also take into account that on There are irregularities on the walls of the room, so we will add allowances of 0.05 m to them.

Note! All values ​​for the calculation are given to one unit of measurement.

Using the method of calculation along the perimeter, we find out how many rolls of the selected material will be required to paste over the room with the given parameters:

1. Room perimeter: (7.5 + 3) x 2 = 21 (m).
2. The height of the canvas, taking into account rapport, offset and allowances: 2.6 + 0.35 + 0.25 + 0.05 + 0.05 = 3.3 (m).
3. Number of cuts per roll: 10.05: 3.3 = 3.05 (pcs.). We perform rounding down, we get 3 full-fledged canvases from the 1st roll and the rest 0.15 m long, i.e. almost the entire roll will be used.
4. In total, you will need cuts per room: 21: 0.53 \u003d 39.62 (m). We round the obtained data up, we get 40 cuts.
5. We consider how many rolls per room are needed: 40: 3 = 13.33 (rolls). We round up the data for a small margin: 14 rolls are needed.

Let's check the values ​​​​in another way of calculating - by the area of ​​\u200b\u200bthe room:

1. Total wall area: (7.5 x (2.6 + 0.35 + 0.25 + 0.05 + 0.05) + 3 x (2.6 + 0.35 + 0.25 + 0.05 + 0.05)) x 2 = 69.3 (m²). Do not forget that we have selected wallpaper with a pattern, so we add the rapport height and offset to the height of the ceiling and additionally take into account allowances for wall irregularities.
2. Window opening area: 2.1 x 1.5 = 3.15 (m²).
3. Doorway area: 0.9 x 2 = 1.8 (m²).
4. The total area of ​​the openings: 3.15 + 1.8 = 4.95 (m²).
5. We find out the required area for gluing (the difference between the total area of ​​\u200b\u200bthe walls and the total area of ​​the openings): 69.3 - 4.95 \u003d 64.35 (m²).
6. Find the area of ​​the wallpaper roll: 0.53 x 10.05 = 5.33 (m²).
7. We calculate the total number of rolls for pasting: 64.35: 5.33 = 12.07 (roll). We round up to a larger integer value and get the desired value - 13 rolls. You can take a chance and round the result down due to a small fractional part in the calculations, however, it is recommended that you always have a free supply of material when selecting a pattern.

If we compare the calculation data for the perimeter and area, a discrepancy of 1 roll will be found, because. in the second case, window and door openings were taken into account, which are not pasted over with wallpaper. You can additionally check the calculations with an online calculator to finally make sure that they are correct, and also clarify them in the reference tables.

Pro Tips for Counting Wallpapers

So that the result of the repair does not disappoint, when calculating the wallpaper and when buying them, you should pay attention to some details:

1. Always purchase rolls from the same lot. Material from different batches may vary slightly in color. The shades are not too noticeable in the roll, but a serious flaw will come to light on the wall.
2. Look carefully at the selected wallpaper. Even a small drawing can have a repeat, which can significantly increase material consumption. If the calculation was performed without taking into account the allowances for combining the pattern, then the wallpaper may not be enough.
3. You can save on footage by using leftovers from cuts of solid panels. They are glued over doorways, as well as above and below the window. In this case, it is necessary that lateral docking according to the drawing is necessarily performed.
4. If the repeat height is high and there is a large enough offset, it is worth buying an additional roll. With a large area of ​​\u200b\u200bthe room to be glued, they buy 1 additional roll for 6 calculated ones.
5. When cutting the canvas, always add allowances for the curvature of the walls, 5 cm is enough for the top and bottom. Take this parameter into account when calculating.
6. For narrow door openings (less than 60 cm), their area is not calculated. In this case, they are not taken into account at all, but the assumption is made that a flat wall is located in their place.
7. When paying for the material in the store, ask about the possibility of returning the wallpaper and be sure to keep the receipt. Returns are allowed within 14 days after purchase, if such a service is available in the store, the roll must be intact and unopened.

The methods outlined in the article on how to calculate how much wallpaper is needed for repairs are used, as a rule, when performing independent work on pasting premises. Each of them has a small error, but all cope with the main computational task.

Despite the fact that the range of materials for the repair and decoration of houses and apartments is replenished almost every year with one or another novelty, wallpaper does not lose its “leadership position” and still remains, probably, the most popular way to decorate walls in residential premises. Moreover, the widest variety of modern wallpapers, made using the most advanced technologies, allows you to complete the decoration in any interior style, authentically imitate wall cladding with many natural materials. And if we add here the relatively low cost and the possibility of independent finishing work, then the popularity of wallpaper gets a completely logical explanation.

Before the owners of housing, who have decided in favor of such a finish, the question will surely arise - how to calculate how much wallpaper is needed per room? We will try to help them with this - below is a convenient online calculator.

For those readers who have already been pasting wallpapers and, therefore, “savvy” theoretically, there should not be any problems using the program. Beginners may have unclear questions - some explanations on the use of the calculator and on the basic principles of calculation are given below.

Good afternoon everyone! There are several ways to calculate wallpaper by the area of ​​\u200b\u200bthe room. In addition, the calculation of the quantity depends on the pattern on the wallpaper, the method of gluing - whether there is a need to customize them or whether they are glued in a row, without selection.

Wallpaper is a magnificent type of decoration, there are a great many of them - for every taste. It is desirable to calculate the wallpaper as accurately as possible so that there is not much waste left, and most importantly, that the purchased amount is enough for the room.

How to calculate wallpaper correctly

We set the size of the room:

• Width = 3 meters
• Length = 5.5 meters
• Height = 2.5 meters

To determine the area of ​​the sticker, you, the perimeter is the sum of all sides of the room, multiply by its height. In numbers it looks like this:

3+3+5.5+5.5= 17m x 2.5m = 42.5m2.

Now from the total area it is necessary to subtract the area of ​​​​openings - this is a door and a window or two. We measure the width and height of the window with a tape measure - they are all different for everyone, but in the example we use the size of the area - 1.5x1.5 = 2.25m2 .

If you also have a balcony door, then I suggest counting the entire balcony block together as a rectangle, since a battery is usually located under the window. Then the calculation will be: 1.7x 2.35 = 4m2, like mine.

Consider the door to the room. By area, it will be equal to 2.1x 0.8 \u003d 1.7 m2

Now let's calculate the total need for wallpaper:

42.5m2 (total area) - 2.25 (window) - 1.7 (door) = 38.6m2.

Or with a balcony 42.5 - 4 - 1.7 \u003d 36.8 m2.

Now you have to select the wallpaper to know its length and width and determine how many rolls you need. For example, you chose wallpaper 10 meters and a width of 0.53 meters, then the area of ​​the roll = 5.3 m2. You need to take 38.6: 5.3 = 7.3 rolls, that is, 8 pieces.

If the wallpaper is meter long, then the area of ​​the roll = 10.6 m2 and you will need 38.6: 10.6 = 3.64 or 4 pieces. If you plan to glue them, then check out the article - how to glue meter-long wallpaper correctly.

Suddenly, someone decided to stick wallpaper in two colors, then you can read about it in the article - sticking wallpaper in two colors. The total need for wallpaper will remain unchanged, just divide them into different colors.

My painter's workers calculate the number of wallpapers in their own way - they do not need the area, since the girls count the number of stripes on the old wallpaper on the walls. If the wallpaper has already been removed, then they measure the width of the wallpaper with a tape measure and apply the specified width around the entire perimeter of the room, calculating the number of stripes. Let's say it turned out 26 strips, which means you need 26: 4 \u003d 6.5 rolls. Round up to seven. And you know, they think just as well as I do with my arithmetic calculations.

Wallpaper calculation with pattern selection

• Wallpaper with a selection of a pattern can be calculated according to the same principle, determining the area of ​​\u200b\u200bthe walls. To choose a pattern, you need to shift the canvases by 15-30cm. So calculate that each roll will take up to 1.2 meters (4 strips x 0.3 m offset). That is, you will already get 3 whole canvases and a piece. Moreover, there is a pattern - the larger the pattern in size, the more you need to move the wallpaper for selection.
• Of course, it is possible, in order to save money, and we all strive for this, to put these pieces into action and paste them over the wall behind the wall, closet and other objects. This is especially true if the wallpaper is expensive, and we are financially economical. There are different situations.
• But I want to tell you that it is not for nothing that they say that "need for inventions is cunning." It is possible to combine the bottom or top of one wall from these meter or one and a half meter pieces, and the second will be from wallpaper of a different tone, texture. Or from them to insert into the wallpaper of another room. Here you have waste-free production, and it will turn out in an original way by design.

Now they offer many tables and “calculators” for calculating, but I am an “unbelieving Thomas” and I count everything myself, measure and calculate exactly according to the above method, which I shared with you.

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.

Table #1 53

Table number 2 designed for wallpaper equal to the width 70 centimeters and 10 meters long.

Table #3 designed for wallpaper equal to the width 106 centimeters and 10 meters long.

Perimeter calculation, table:

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

Roll size: 0.53 m / 15 m = 7.95 sq.m

Roll size 1.06 m / 10.05 m = 10.65 sq.m
