How to calculate the wallpaper on the room: repair inexpensively

The desire to make repairs and upgrade the appearance of the walls always begins with the choice of material. In most cases - is the wallpaper. However, the most common problem is not how to determine their color and texture, and is not to be mistaken with the number of rolls. It is therefore important to know how to calculate the wallpaper on the room, so as not to have to buy more stuff or to store excess, lamenting the wasted finances.

Where should begin the calculation of wallpaper for repair

Wallpaper quantity calculation begins with the selection of the material for pasting of a room or an apartment. Even if known about the desired color and style of wallpaper, there are nuances, which are:

• in wallpaper patterns;
• in the roll width;
• in roll footage.

All these factors have a direct impact on the amount of the purchased material costs and the final result.

The information that is required is contained in the marking roll. Manufacturer necessarily indicate running meters and width. 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 webs having a large width. most often it is the stylistic prints (wallpapers). Roll length can also vary, but typically, this value is 10.05 meters, although there are variations on the 5.5 and 25 meters.

Drawing on the wallpaper plays an important role in the process of pasting the walls, it depends on him, on what value will shift cutting roll to the finished wall looked completely solid and was not visible joints.

All wallpapers are performed by repeating a certain pattern at regular intervals - rapport. The higher the rapport, the more centimeters from each roll will be cut to fit. Manufacturers specify these parameters directly on the packaging, using special labeling bias and panels joints.

Rapport is not taken into account when buying a plain wallpaper with abstract fine pattern or stripes. In all other cases it will have to combine in a horizontal plane so that each began with the segment of the same element. When rapport with combining butt "extra" may be almost completely the height of a repeating pattern.

It should also take into account the option of when flowery patterns that look great on the wall, when glueing cause excessive consumption meters of the roll. They dock goes with the largest displacement. This value can be recognized by the labeling and pre-estimate how much will have to cut the material, whether the appearance of the alleged financial cost.

Proposed range, stopping at a few options, you must first evaluate before making for the calculation of the amount of wallpaper on the room. Consideration should be labeled carefully and remember or write data. This will help in further calculations.

How to calculate the wallpaper on the room: options, formulas, especially

To know how to calculate the right amount of wallpaper, you need to use one of the methods:

• along the perimeter walls and the number of cut strips;
• area of ​​all walls and papered surfaces;
• the use of online applications and services calculators wallpaper.

Each of these methods has its own error in the calculations, but to use them more efficiently than buying wallpaper generally without any clarification. Improvised will need to prepare a tape measure for measuring, paper and pen for notes and calculator. Calculate the amount of wallpaper on the room is simple, there is not need outstanding mathematical abilities, the main thing - to understand the principle and follow it.

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

How to calculate the amount of wallpaper on the room around its perimeter

Perimeter - is the sum of the lengths of all sides of the polygon. In this case, the polygon is a room in which the repair will be carried out. Take the tape measure and measure the length of the wall from corner to corner, excluding skirting and frieze. If the room is designed with a bay window, and be sure to measure each his wall. Take the time to perform measurements of all the walls, because it may be that the surface that is visually parallel, the reality is not quite the same length.

Now it is possible to calculate the perimeter of the room as the sum of all the measured sides:

• F = the total length of length 1 + 2 +... + length N,

where N - number of walls in the room.

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

Useful advice!The ceiling height may vary within the same room for a few centimeters. Therefore, you should perform several measurements and to select the highest value.

When the known height of the walls, you can see the length of the cut cloth wallpaper. In this case, the data will need rolls marking selected previously in the store:

• L = web height of the room height rapport + + + offset value oversizes by 5 cm on the top and bottom bleed

Now again, you must apply to labeling in order to learn the length of each roll, because the next step is to calculate the number of cuts of fabrics in one roll:

• number of cuts in the roll length = 1st roll / length of 1st leaf

Using the known width of the roll, you can calculate how many cuts need for pasting the entire room:

• number of cuts at room rooms = / roll width perimeter

And finally, the main calculation - how to calculate the number of rolls of wallpaper in the room:

• number of rolls = number of cuts on the room / number of cuts in a roll

When you try to calculate the number of rolls of wallpaper calculator will not integer. It should be rounded up, as the rolls are not sold in parts.

Full algorithm how to calculate the number of rolls of wallpaper on the perimeter of the room, will be as follows:

1. Make measurements of the length of all walls.
2. Perform measurements of the room height.
3. Calculated by the formula perimeter of the room.
4. Find out the length of one blade for pasting.
5. Calculate the number of cuts per roll.
6. Calculate the total number of cuts for all walls.
7. Find out the required number of selected rolls of wallpaper.

Important!When calculating webs for the one roll must be rounded value obtained in the smaller side to know the number of whole cuts. When calculating the final amount of cuts to the room round the need, on the contrary, in a big way, to ensure enough wallpaper pasting.

How to calculate the amount of wallpaper paste over the square surfaces

perimeter into account in determining the amount of wallpaper for repair - this is not entirely accurate method because it does not take into account the presence of the wall openings for doors and windows. For more accurate data necessary to calculate the area of ​​the walls, the calculator can handle this easily, but measurements in the room will have to do more. Require data size of the wall, all available openings, projections, recesses, taking into account topography and layout of the room.

Originally calculated by the calculator, the wall area - each separately, using the formula:

• Wall area = length x wall height of the wall

If the selected wallpaper has a repeating pattern and offset, then to the height of the wall you want to add height and offset rapport. Their values ​​are listed on the roll pack.

Then the results are summed. Next, in a similar way calculate the area of ​​all openings and also find their sum. Next, the calculator for calculating the area of ​​the walls, which will be used for wallpapering:

• wallpaper pasting area = total wall area - total area of ​​the openings

These data are insufficient to determine the number of rolls. To find out the total value of required pre-calculate the area, which can cover 1 wallpaper roll:

• Area 1 st = width of the roll 1st roll length x 1st roll

Roll width and length are taken from the marking of the selected wallpaper of the room, it is already defined by the manufacturer on the label is attached to each material.

Now, the final step - calculation of the total number of rolls needed to repair:

• = the number of rolls wallpaper pasting area / area 1st roll

Most likely, that when calculating the rolls of wallpaper of the room space calculator will not integer. For the final result it is to be rounded to the increase in a big way.

can be formulated in full in area calculation algorithm is as follows:

1. Perform measurements of the sizes of all the walls and the openings of the room.
2. Calculated from the formula each wall area and sum the values ​​obtained.
3. Learn a total area of ​​openings by summing pre-calculate the area of ​​each of them.
4. Calculate the difference between the total area of ​​the walls and the total area of ​​openings. It is the surface for pasting wallpaper.
5. Explore the area of ​​one of the selected roll of wallpaper.
6. Settle on a formula for determining the number of rolls needed to repair.

Graphical method: calculate the wallpaper on the room, using visualization

Correctly calculate the amount of wallpaper, as shown by the methods described, simply. However, for clarity, the calculations can be represented graphically, in which case they will be more readily perceived visually. In addition, it will be clear where to begin gluing, where the cutting, forming angles, etc. will be

For a graphical method, you must:

1. Draw unfolded a sketch of the room given the size of the wall and all the openings.
2. Show on the diagram all the known width and height data.
3. Apply a layout grid paintings Wallpaper, knowing their width.
4. Count the number of the resulting cuts.
5. Calculate the web length and number of cuts in a roll, as was done in the method of calculating the perimeter.
6. Calculate the amount of room for wallpaper rolls, rounding to an integer value in a big way.

On the other hand, if the width of the new wallpaper coincides with the width of the old, which papered room, you can count the number of blades required directly on the walls.

How to calculate the wallpaper with the help of online services

Internet helps in solving many problems, so the reluctance to count manually, you can calculate the number of online wallpaper. On specialized sites published different kinds of calculation programs. It is recommended to select those which require the greatest number of spaces to indicate the parameters and characteristics of the chosen material.

Calculation wallpaper online calculator is based on data that are loaded into it for processing. Necessarily require the parameters of walls: the length and height. If the calculator quality is selected, it will be the column to fill the size of door and window openings, as well as accounting pattern of displacement.

Important!Pay attention to the unit of measurement for all fillable fields online form calculator. Calculate the wallpaper on the room is acceptable in meters or centimeters. For one form only used the same unit of measurement.

Whatever it takes to get a result - this correctly fill out all fields and press the calculation button. The program will instantly calculation. With the help of online calculator to calculate the wallpaper can be directly in the store, so easier to navigate in the price range of choices.

The method to calculate the wallpaper, wall-adjusted design solution

Inspired by the design decisions can be made in the same room pasting a combination of several kinds of wallpaper. It is bold and original, if you choose the correct combination. Calculate the number of wallpaper in this case can be any of the above methods, only necessary to consider each type separately material.

For example, the insert can occupy the whole area is completely one of the walls. Then determine the number of basic wallpaper for the 3 wall plus separately recognized, how many rolls you will need to insert pasting. Complexity can arise if the chosen combination of materials has a different width of the roll, so pay heed to labeling. Particular care should be addressed to the measurements, if used to insert 3D print or wallpapers.

Another option: the decor does not take a whole wall, but only part of it, and there is a space filled with the basic wallpaper top, sides, and possibly below (organization of panels). In this case, decorated with paste is taken as an additional wall opening. You can find the wallpaper on the room as a calculator online or manually. Calculation of the material flow on the inlay is made individually by any method.

If you intended to paste over the wall with the organization of panels and trim border, then to the top of the wallpaper and bottom (panels) produced separately calculations convenient way of allowing for the selected material.

Down Calculator: how to calculate the wallpaper on the room on tables

If difficulty is calculated using simple, but many formulas and calculator, wallpaper for the walls may be calculated in any other way. For this purpose the auxiliary reference table created with the width and length rolls, and the geometric dimensions of premises. The values ​​stated in them, can serve as a guide for the purchase of materials for the repair and test of self-performed mathematical calculations on the perimeter and area of ​​walls.

Sheets were prepared, excluding the repeat pattern or a bias, so the desired values ​​necessary adjust the height of ceilings, adding to the measured values ​​of the additional data space pattern features. Thus, the measured height of the ceiling is more than the height of rapport, plus the height of the displacement. To be scrupulously accurate, it is necessary to add allowances for the curvature of the walls for the bottom and top 5 cm. By total value and should be guided in the selection number from the table rolls.

Important!The tables for the estimated floor area is taken, rather than the total area of ​​the walls, as in the mathematical calculations.

EXAMPLE mathematical calculation of the required amount for the room wallpaper

To clearly was as described in the article operate the calculation methods calculate the amount of material execute a specific example.

Suppose you want to paste over the room where one window and the door are present. Initially, perform measurements on site. For example, the selected room get:

• House length - 7.5 m;
• width of the room - 3 m;
• ceiling height - 2.6 m;
• window sizes - 2,1h1,5 m;
• door dimensions - 0,9h2,0 m.

Assume that for pasting been previously selected pattern with a large picture: repeat height - 0.35 m and offset - 0.25 m resolution. roll:. width - 0.53 m, length - 10.05 m Also take into account that on the walls of the room there are irregularities, so add them allowances of 0.05 m.

Note!All values ​​for the calculation are given for one measurement units.

Using the method of calculating the perimeter, we know how many rolls of selected material required for pasting premises with the specified parameters:

1. The perimeter of the room (3 + 7.5) x 2 = 21 (m).
2. The height of the webs with the rapport and displacement allowance: 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.). Perform rounding down obtain 3 full web from 1st roll and the residue was 0.15 m long, i.e. almost the entire roll to be used.
4. Total required cuts to the room: 21: 39.62 = 0.53 (m). Rounding the data in a big way, we obtain 40 cuts.
5. We consider how much you will need all the rolls at the room: 40: 3 = 13.33 (roll). Rounding data in a big way for the small stock: to 14 rolls.

Check the value of another method of calculation - on premises:

1. The total area of ​​the walls (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 chosen the wallpaper with a pattern, so the height of the rapport and the offset is added to the height of the ceiling and additionally take into account the allowances on the wall roughness.
2. The area of ​​the window opening: 2.1 x 1.5 = 3.15 (m²).
3. The area of ​​the door opening: 0.9 x 2 = 1.8 (m²).
4. The total area of ​​the apertures: 3.15 + 1.8 = 4.95 (m²).
5. Learn device for pasting area (the difference between the total area of ​​the walls of the openings and total area): 69.3 - 4.95 = 64.35 (m²).
6. Find the area of ​​wallpaper roll: 0.53 x 10.05 = 5.33 (m²).
7. We compute the total number of rolls for pasting: 64.35: 5.33 = 12.07 (roll). Perform rounding to the greater whole values ​​and obtain the required value - 13 rolls. It is possible to take a chance and round the result in the lower side due to a small fractional part of the calculations, but it is recommended in the selection pattern always have free stock material.

If we compare the data of calculations on the perimeter and area, you find a discrepancy in 1 roll, because in the second case of windows and doorways were taken into account, which are not pasted wallpaper. You can also check the calculations still online calculator to be convinced of their correctness, and to clarify the reference tables.

Professional advice regarding the counting of the number of wallpapers

To summarize the repair did not disappoint, in the calculation of the wallpaper and when you buy should pay attention to some details:

1. Always purchase the rolls from the same batch. Material from different batches may differ slightly in color. Shades are not too noticeable in a roll, but on the wall revealed serious drawback.
2. Look carefully selected to wallpaper. Even a small pattern can be rapport, which can significantly increase the material consumption. If the calculation was carried out without taking into account allowances for alignment pattern, the wallpaper may not be enough.
3. You can save on the footage using residues from cuts of whole cloth. They pasted over doorways, as well as the top and bottom of the window. It is necessary to always follow the lateral dock on drawing.
4. If the height of the rapport is great and there is a sufficiently large displacement, it is necessary to buy an extra roll. When large-area shop premises papered 1 additional roll 6 calculated.
5. When cutting fabric always add allowances on the curvature of the walls is sufficient to 5 cm for the top and bottom. Consider this when calculating.
6. For narrow doorways (less than 60 cm) is calculated not their area. In this case, they are generally not taken into account and accepted the admission that in their place is a smooth wall.
7. When paying for the material in the shop ask about the possibility of return of wallpaper and be sure to keep the receipt. Returns are allowed within 14 days of purchase, if this service is present in the store, the roll must be whole and unopened.

Set out in Article methods how to calculate how much wallpaper you need to repair, used, usually with independent performance of works on pasting the premises. Each of them has a small error, but the main computational task handle everything.
