How to calculate linear meters of window slopes

Calculating a linear meter - how to calculate correctly? Review

Inexperienced or novice builders do not know how to calculate linear meters.
These parameters are used when performing repair or construction work, even when purchasing furniture. The calculation of a linear meter arises when it is necessary to facilitate the calculation of the quantity of products, for example, linoleum, curtains, skirting boards, carpet, pipes, and the like.

This concept is almost no different from the concept of length, only the width of the material is taken into account.

Most often, the width of a certain product or floor covering is considered a standard value and if it is necessary to calculate a linear meter, then they are not taken into account.

What is this unit of measurement?

If we define a linear meter, then this is the measurement value of long materials, molded products.

Equal to one linear meter to a regular meter (m). So in everyday life it is customary to measure the length of structures, raw materials, products, regardless of their width or height.

Calculating the cost of long goods using linear meters is easier than taking the price per square meter as a basis.

The ability to independently draw up an estimate, perform correct calculations, and understand the definition of a linear meter will eliminate the risk of being deceived and prevent errors of overexpenditure or shortage of materials.

How much does wallpapering cost?

So, the cost of wallpapering is measured in rubles per square meter of surface to be finished. At first glance, everything is very simple - the payment to the finisher needs to be divided by the area of ​​the walls. The payment has been announced by the master, all that remains is to calculate the square footage of the finish.

The lengths of all the walls in the room are measured and summed up; the resulting result is the perimeter. For example, the perimeter of a room 4 x 2.5 is equal to (4 + 2.5)x2 = 13 square meters. By multiplying this parameter by the height of the ceilings or the wallpaper area, you get the total area of ​​the side surface of the room, which includes windows and doors. For example, with a ceiling height of 3 m, this area will be 13 m x 3 m = 39 sq. m.

Suppose the situation in this room is this: the wallpaper needs to be replaced with new ones, and the painter asked for 25 thousand rubles for this work. Thus, gluing 1 sq. m. canvas without the cost of materials will cost 25,000 rubles. / 39 sq. m. = 641 rub./sq.m. However, it should be taken into account that the concept of “pasting” in this case implies a complex of works from removing old wallpaper to installing new ones, between which other operations will be performed - priming, and possibly leveling with putty and sanding.

In addition, other factors also influence the price of wallpapering :

1. Type of canvas by material of manufacture. The cheapest way to work is with vinyl on non-woven fabric and with glass wallpaper for painting. They charge a little more for paper wallpaper and almost twice as much for textile fabrics of any design.
2. Wallpaper design. For sticking 1 sq.m. wallpaper with a selection of patterns will be asked for 20-50 rubles. more than for plain ones. On average, finishing with photo wallpaper will cost twice as much as this price.
3. Room height and wall configuration. Working from a stepladder is more difficult; the presence of niches on the walls is also a complicating factor.

• On average, wallpapering the ceiling will cost one and a half times more than wallpapering the walls.

Identical to the prices for laying ceramic tiles, contractors often charge more for hanging expensive wallpaper than for working with canvases of the same material, but of lesser cost. In such cases, it is especially important to discuss mutual obligations with the craftsman in detail: the customer pays the stated price, the contractor undertakes to compensate for damage in case of damage to the material.

Please note that contractors’ statements about free measurements, delivery of materials and other bonuses are marketing techniques. In fact, everything “free” is also included in the prices for repair work.

Accounting for window and door openings

When talking about the surface area to be finished, we mean walls, but not all professionals calculate this value in the same way.

If you follow the wording, then window and door openings should not be included in the finished surface. It can only include the area of ​​the slopes, but when they also plan to cover them with canvas.

Consequently, the contractor must calculate the perimeter of the room, multiply it by the height of the decoration and subtract the square footage of windows and doors from the result. Many contractors do exactly this, after which they multiply the resulting value and their price (the price of performing a set of necessary operations per 1 square meter). By performing a reverse calculation, the customer can check this value:

As a rule, this technique does not raise objections among homeowners, since the calculated figures correspond to the facts. However, the method contains inconveniences for contractors. Firstly, measuring openings and taking their area into account in calculations requires additional time. Secondly, wallpapering a window or door is more difficult than covering a whole wall - you need to take more measurements, arrange small pieces of canvas (most often with the selection of a pattern), after drying, trim the edge of the canvas around the perimeter of the opening, and sometimes also glue it. The result of these operations performed by the contractor is a reduction in the customer's costs, which is not logical. But if, when calculating the volume of work, we use the full area of ​​the side surface of the room, then it will include openings, but they were not covered with wallpaper. In such a situation, the actual consumption of wallpaper will be less than the finishing figure specified by the master, which is most often perceived by the homeowner as an attempt to deceive.

To avoid such disagreements, professionals use a compromise calculation option. To do this, calculate the area of ​​the openings and multiply it by the price for wallpapering in this room. The resulting cost is included in the payment for the walls actually finished with canvas (summed up with it), and divided by the finishing area. The final result is presented to the customer as a gluing price.

In the example given earlier, it would look like this:

• the total area of ​​the side surface of the room is 39 sq. m. • excluding windows and doors, the price quoted was 640 rubles/sq.m. • window and door openings 2.25 + 1.5 = 3.75 sq. m.

640 x 3.75 = 2400 rub. – payment for operations with openings; 39 – 3.75 = 35.25 sq. m. - area of ​​the surface to be finished; 640 x 35.25 + 2400 = 24960 rubles; 24960 / 35.25 = 708.08 rub./sq.m. – a new price taking into account the execution of operations with openings, rounding which will give 710 rubles / sq. m.

Note: the figure by which the gluing price will be increased must be commensurate with the labor costs for finishing the openings, so that the price of the work is competitive - not higher than the regional average.

Popular questions when calculating windows

How to calculate correctly?

Despite the availability of multifunctional calculators, they are limited in several parameters, especially when calculating windows and window frames. If you order it entirely in non-standard sizes, you must take into account additional problems that may arise during operation.

In other words, non-standard windows require additional parameters, because of this you will have at least one question: “how to calculate the weight?”

Metal-plastic window with two movable sashes

Formula for calculating window weight

An accurate weight is necessary to determine the load that will act on the hinges. If this is missed, the window may bend under its own weight, especially in areas of movable elements and sashes.

These parts should not weigh more than 60 kg, so the average is around 50 kg. In the photo you can see the main point that is affected by the mass of the sash.

Movable sash window hinge

In order to calculate the required weight, it is necessary to take into account 3 standards used by most manufacturers:

1. Thickness 4 mm;
2. Weight of 1 m2 of single-chamber glass with frame 25 kg;
3. Weight of 1 m2 double-glazed window with frame 35 kg.

Based on these data, we can calculate the mass based on the dimensions using a very simple formula: multiply the window area by the standard 1 m2 of the selected glass unit. Don't know how to calculate the window area? You just need to multiply the width by the height.

For example, you chose a single-chamber double-glazed window with a height of 140 cm and a width of 90 cm. Let’s find out the area by converting the indicator into meters: 1.4*0.9= 1.26 m2 – the area of ​​our window. Now we calculate the mass: 1.26 * 25 = 31.5 - we get the required weight.

Basic parameters of a plastic window

For fixed-type windows, you do not need to carry out a weight calculation, since they do not have movable parts.

Accurate area calculations

The larger the structure, the more difficult it will be to accurately measure it. Therefore, the question of how to calculate the window area in square meters on a large scale is very relevant. But everything is not as difficult as it seems at first glance:

1. First, you need to divide the entire structure into the metal-plastic sections of which it will consist.
2. After this, you need to find out the area of ​​​​each section, including both fixed and movable windows.
3. Then all you have to do is add up the entire area, and you will get the total area of ​​the entire structure.

Large metal-plastic windows

The final stage

As you can see for yourself, the PVC window calculator does not take into account the total weight of the windows, so you will have to find it out yourself. But if you have only a vague understanding about the installation and design of plastic windows, then it is better to use the services of a specialist.

Moreover, the company often provides this opportunity for free. But now you already know how to calculate a square meter, weight and area of ​​a window, so you can do the calculations yourself or check the quality of a specialist’s work.

Ready-made plastic window layout

With your own hands you can make almost all the measurements necessary to order plastic windows. But no one has yet found exact instructions on window sizes taking into account price, since each company provides individual options.

Wooden window slopes

Refined and elegant wooden slopes are the most ideal option for finishing wooden windows. They will harmonize with windows made of any wood (oak, pine, larch), and in combination with a wooden window sill, the window will have an aristocratic look.

Wooden window slopes can adequately replace plasterboard, plastic or plaster finishes. It is believed that wood will not last as long as, for example, PVC, but this is not entirely true.

Wooden slopes - an elegant choice

With high-quality processing and the right choice, a wooden slope in its technical characteristics is not much inferior to a plastic one. Also, do not forget that in many interiors where wood is mainly used - windows, furniture, decoration, plastic slopes will not look entirely appropriate.

Is it possible to calculate the cost of a kitchen by the number of linear meters?

A linear meter is a conventional unit of measurement of its length. This concept is used when purchasing a kitchen set in linear meters for an approximate calculation of its cost. This is a kitchen set in which each subsequent meter uses the same amount of material in value terms as the previous one, and differs only in the different spatial arrangement of structural elements.

In this case, the task of selecting and determining the approximate cost of a set is much simplified, using this concept for the kitchen. To do this, you need to know the average price of 1 linear meter of headset.

This way you can approximately calculate the price of any similar kitchen, knowing its overall width dimensions.

Examples

Let's say the fenced area has the shape of a rectangle with sides of 30 m and 20 m. First of all, we determine how much the perimeter will be. And it will be equal to the length of the fence. To do this, the lengths of the sides are added and multiplied by 2. The perimeter of such a section will be 100 m.

For further calculations, it is enough to know the width of the raw materials used and the height of the fence. For example, it will be equal to 1 m, and the raw material will be corrugated board. As a result, you will need to buy 100 sheets. But just in case, it’s better to buy a little more to have a reserve.

If the width is approximately 2 m, a minimum of 50 sheets will be required. That is, to determine how many sheets are needed, you need to divide the perimeter by the width of the material. In order to determine how many meters of material will be required to build the fence, we multiply the perimeter by the expected height.

That is, to install a meter-long fence along a 100-meter perimeter, 100 linear quantities of building material will be required. To build a two-meter high fence, you will need 200 m of the same building material, and so on.

If the price of one linear value is known, then it is not at all difficult to calculate how much the building materials needed to install the fence will cost.

What goods are measured by linear meters? A linear meter is a unit of measurement of the length of such goods:

• for which, when selling, the values ​​of width, height or cross-section diameter do not matter;
• which, when used, require joining of its fragments together;
• intended for fencing, for example, metal fences or fences made of other materials.

Such goods in stores come in the form of rolls, reels, slabs, etc. For example:

1. come in the form of rolls:
   carpets,
2. asbestos sheet,
3. linoleum,
4. fabrics,
5. artificial turf coverings,
6. polyethylene film
7. and etc.;
8. come in the form of bobbins:
   cables,
9. wires,
10. threads,
11. and etc.;
12. come in the form of slabs/cuts:
    facing stones,
13. laminate,
14. plywood,
15. furniture material,
16. and etc.
17. in the form of long “sticks” there are:
    skirting boards,
18. cornices,
19. flooring boards,
20. slats,
21. and etc.

In order to avoid making a mistake in correctly determining the quantity of this product when purchasing the product you need, measured in linear meters , you must know exactly the parameters of the room, product, material for which you are purchasing this product.

How to correctly calculate the quantity of goods? Below are examples of calculations.

Calculation when purchasing carpet

Let's say you want to buy carpet for a room with an area of ​​20 m2 (5 m long and 4 m wide). It is important for you that the length of the room is completely covered; as for the width, it is acceptable that there may be places at the edges of the room that are not covered. You come to the store and in front of you there is a large selection of carpets, how can you navigate the situation correctly?

You liked two types of carpets (in color and pattern): one costing N rub./p. m., the other - M rub./p. m. The difference in the price of carpets is explained by their different widths, which are taken into account in the price (one is 3.0 m wide, the other is 3.5 m). Question - How much carpet should you buy?

The peculiarity of choosing a carpet is that it must be a single piece, without joining, so the selection criterion should be its width.

Thus, you should buy 5 m of the covering whose width suits you best.

Calculation for the purchase of linoleum

You go to buy linoleum for the kitchen, 2.5 m wide and 5 m long. In the store you can see rolls of different widths: 1.5 m, 2.0 m and 2.5 m. How much linoleum should you buy? You should choose linoleum 2.5 meters wide (i.e. the width of the kitchen) and buy it in 5 linear meters and cover the kitchen floor in one piece. But this is the ideal case when the width of the linoleum matches the width of the kitchen.

What to do if the kitchen is 3 meters wide? In this case, you cannot cover the floor with one piece. We have to think about how to join the two pieces. This means that for this you need to take 10 linear meters from a roll 1.5 m wide (or ask the seller to cut two pieces of 5 linear meters each, so that you don’t have to cut it yourself later). In this case, the joint will run exactly in the middle of the kitchen. Linoleum can be laid not only in its length, but also in its width, thus varying the location of the seam and the amount of linoleum depending on the area of ​​the surface to be covered.

Features of facade work

Depending on the finishing materials, there are many types of facades. Options using decorative bricks are popular. Surfaces can be given a “wet” effect, plastered for painting, finished with porcelain stoneware, stone. Facades lined with cassettes, panels, siding, etc. are widespread.

The production of facade work using each material has its own characteristics:

• Porcelain tiles are laid after careful preparation of the surface. Markings are applied to it, identifying the mounting locations for brackets and profiles. Next, install the waterproofing film and insulation. After installing the vertical profiles and fire stops, they begin the final stage of facade work - tiling;
• Open-type metal cassettes are laid step by step on the frame racks. The side shelves of the next panels should overlap the previous ones. During installation, the upper part of the closed-type cassettes is screwed to the sheathing with self-tapping screws. The bottom one goes behind the panel of the bottom row;
• Before finishing with stone, it is necessary to clean and level the surface. The drawing is first laid out on the ground. Next, the material is treated with cement mortar or glue and pressed against the wall;
• Carrying out façade work using composite slabs involves installing panels on a metal frame. Wooden walls can be pre-primed with compounds with antiseptic properties.

Types of facade work

Redecorating. This type of work involves changing the top layer of the coating.

Major renovation. The need for this procedure arises when there are signs of destruction.

Installation of a ventilated facade. The system consists of a base - a frame and cladding. The latter is played by composite panels, steel sheets, vinyl siding, etc.
