If you decide to make or at home, first of all you need to choose and understand how many of them you need. To do this, you need to correctly calculate the area of all surfaces in the apartment. Of course, you can resort to the help of professionals, while spending extra money. And you can do it yourself. This article is devoted to how to calculate the area of a room of different shapes.

Why is it necessary to know the area of \u200b\u200bthe room and what is required for calculations?
In what cases is it necessary to calculate the area of \u200b\u200bthe room?
- Of course, first of all to determine the quantity to repair. Many people buy them with a margin, and return the surplus to the store. However, in this case, a lot of time is lost, moreover, not all stores provide such a service. Therefore, it is more expedient to correctly calculate the area of \u200b\u200ball surfaces before shopping.
- In addition, knowing the area is easier. After all, even the cost of the work of employees in most cases depends on how many square meters they have to process.
- The amount also depends on the area. However, in most cases, complex calculations are not resorted to when choosing fixtures; this issue is usually resolved empirically.
- And the last. One of the main quantities in the apartment is the volume of the premises (in this case, it is necessary to multiply the area by the height), because depending on it they select.
Important! Be sure to check the area when buying an apartment, especially if you bought it in a new building. After all, the size of utility bills and often the cost of the living space itself depend on it. For example, the developer (in the case of equity participation in construction) is obliged to reimburse the cost of the missing square meters.
Thus, there are a huge number of reasons why it is necessary to correctly calculate the area of \u200b\u200bthe room. But where to start? First you need to prepare the measured room and tools.
It is desirable to carry out measurements in a completely vacant room. If this is not possible, clear at least the areas near the walls, because it is along them that measurements will be taken.
Important! If the room is rectangular, check the correctness of its shape before starting measurements. To do this, compare opposite diagonals. If they are equal, you have a regular equilateral rectangle.
So, to determine the area of \u200b\u200bthe room, the following are needed:
- Roulette. Of course, the electronic device is more convenient, but it has a large error. In addition, complex shapes cannot be measured with such a tape measure; problems can also arise when working with protruding elements. Therefore, the optimal set is a simple tape measure and a ruler. The main thing is to check their accuracy, since many old or children's devices have a decent error.
- Pencil.
- A sheet of paper for calculations and recording results.
- Calculator.
In addition, you may need a long ruler to check the evenness of the walls.
How to calculate square meter?
In square meters, in most cases, the area of \u200b\u200bany surface is calculated. So how to calculate square meter?
To begin with, if the room is rectangular, you need to measure its length and width. In this case, it is desirable to use a tape measure with applied divisions of centimeters and millimeters. If you can only find a ruler with feet, it doesn't matter, they can be easily converted to square meters.
Further, the two obtained values \u200b\u200bin centimeters are converted into meters (it’s easier to do it right away) by dividing by 100. Then the two values \u200b\u200bare multiplied, the resulting value is the area of \u200b\u200bthe room in square meters. If you have feet, first multiply the resulting values, so you get square feet. Then, to convert to m 2, multiply the resulting value by 0.093 (if the measurements were made in yards, multiply the result by 0.84). In this case, the calculator is an excellent solution for calculating square meters.
Interesting! On the Internet, there are many online square meters calculators for calculating the area of \u200b\u200bthe room. If a computer is at hand, this method will be the fastest.
When the figure is received, round it up to 2 decimal places, a more accurate value will be redundant.
How to calculate the area of a room yourself?
The perfect room is a rarity. How to find out the area of a room with ledges, niches or curved bevels? The simplest thing is to measure the lengths of all the walls, as well as the angles between them, and then draw a plan of your room on a piece of paper (the scale will most likely fit 1:100, that is, one centimeter on paper will correspond to one meter in the room) . Then it is necessary to divide the room into regular shapes (rectangles, triangles, circles, and so on), if possible, and using the formulas for calculating the area, determine the quadrature of each section.
Below are the most popular figures, descriptions of the calculation methods of which will help answer the question: "How to calculate the area of \u200b\u200bthe room yourself?".
How to find the area of a rectangle?
How to calculate the area of a rectangle yourself? A regular rectangular room is the simplest case. To calculate the area of a rectangle, simply multiply its length and width. However, there are also some nuances in this situation:
- After measuring one of the sides, the second must be measured strictly perpendicular. Otherwise, measurements can be obtained with a significant error.
- To avoid inaccuracies, measure both parallel walls, as often their lengths are somewhat different, and for accuracy it is desirable to take their arithmetic mean. That is, add their values and divide by 2.
- Do not forget to subtract all kinds of protrusions from the resulting area (or add niches).
Interesting! There are many programs on the Internet for calculating the area of a rectangle, the online calculator is the simplest and most convenient of them.
The procedure for carrying out repairs in the room requires a mandatory calculation of the area of \u200b\u200bthe walls, ceiling and floor. Since during the purchase of building materials, these values \u200b\u200bhelp not to be mistaken in their quantity. We will talk about methods and examples of calculating the area of \u200b\u200bthe room further.
Reasons for calculating the area of \u200b\u200bthe room
There are a large number of reasons why the area of \u200b\u200bthe walls, ceiling or floor in a room is determined. In some cases, data on the total area of the room is required. We suggest that you familiarize yourself with the most common reasons for determining the area of \u200b\u200ba room or its individual parts:
- if work is planned to install suspended ceilings, then it is necessary to determine the total area of \u200b\u200bthe ceiling to determine the amount of materials used in the work;
- when installing stretch ceilings, you also need to calculate the total area of \u200b\u200bthe ceiling in order to pre-plan material resources;
- for painting or finishing the ceiling, you should also know its area, almost all paint and varnish products and primers have a consumption rate per square meter in their technical specifications;
- finishing walls with drywall requires calculating the total area of \u200b\u200bthe walls to purchase the right amount of material;
- when hiring builders, for example, to finish the floor with tiles, each square meter has a certain cost, which is calculated at the end of the work;
- when selling a house or when decorating it, such a parameter as a living area, the area of \u200b\u200bthe kitchen and other rooms is also of particular importance.
Room area: calculating floor area
There are various reasons for determining the floor area: repair and purchase of materials for its finishing, thermal insulation, calculation of usable area, etc.
The easiest way to determine the area of \u200b\u200ba room is a square or rectangular shape. In this case, you will need the value of the length and width of the floor, which are multiplied by each other. This option does not require the release of the room from cabinets and other furniture. It is enough to simply measure the distance. However, if there is a fireplace in the room, its area should be subtracted from the total result obtained.
In principle, all items that are permanently on the floor and cannot be moved, such as built-in wardrobes, are calculated from the total floor area.
More difficult is the calculation of the floor area in a room that has an irregular shape. Standard rooms are, of course, rectangular or square in shape, although there are rooms with all sorts of niches, recesses, arches, ledges, etc. This option for calculating the floor area is more complicated, since it requires calculating the area of \u200b\u200bthe figures that make up the room separately.
To calculate the total area, you should divide the space into several regular shapes, in the form of rectangles, trapezoids, squares, etc. For example, if the room has an L-shape, then it is enough to divide it into two rectangles, calculate the area of \u200b\u200beach of them and summarize the results.
If the room has an L-shape, but it does not run at a right angle, then in addition to two rectangles, it also contains a triangular space, the area of \u200b\u200bwhich is also calculated. To calculate the area of a triangle, it is enough to multiply one leg by another.
In the presence of semicircular fragments in the form of cylindrical or segmental particles, the calculations become more complicated. To calculate the floor area in such a room, it is also necessary to divide the space into several parts, the area of \u200b\u200bwhich is calculated separately.
There are options for rooms that have different floor levels, that is, elevations or slopes. Thus, the room is divided into several zones. For example, in the kitchen there is a dining room and a working part. The same thing happens with the ceiling, for example, multi-level. To calculate the floor area with ledges or hills, you should again divide the space into parts in the form of rectangles or squares, and measure those very protrusions with a ruler and calculate their area. In this way, it will be possible to calculate the total area of \u200b\u200bthe room.
Please note that in this case it is preferable to use a tape measure, which is installed near the base. In addition, you will need a pencil and a notebook to write down all the values. As a result, buying paint and determining the amount of finishing material for the floor will be completed quickly.
Do not measure from the wall as it may be curved and will cause inaccuracies in the floor area determination process. Particularly difficult are the works on determining the floor area, on which there are ledges in the form of a semicircle or wave. This situation involves measuring each of the arcs, finding the radii and splitting the area into several geometric shapes. By determining the area for each of them, the general formula for the asymmetric segment is calculated.
Determining the area of a rectangular room and ceiling
Rectangular room is the most typical and common option. To calculate the area, it is enough to multiply the length of the room by its width. For example, if the length of the room is 3.40 m and its width is 5.20 m, then 3.40x5.20 is enough to determine the area of \u200b\u200bthe ceiling, resulting in 17.68 square meters. To calculate the perimeter of the ceiling, another formula is used, which implies the sum of twice its length and width. That is, the perimeter of the ceiling is equal to 2x3.40 + 2x5.20 = 17.2 m.
Therefore, in the process of purchasing profiles, 17.2 meters of material will be required. However, it is recommended, even when making the most accurate calculations, to buy material with a margin of 10-15 percent to compensate for various kinds of mechanical damage and joints.
What is the area of the room in which there are niches and ledges
To determine the area of \u200b\u200bsuch a room, you should work hard and perform the following actions:
1. Make a project of the room, taking into account all the design features.
2. Measure and mark heights and lengths for all flat walls.
3. Using a ruler and a square, divide the space into several zones, in the form of regular shapes.
4. Each of the sides of the figure should be measured and marked in the project.
5. According to the formula for calculating the area of \u200b\u200ba figure, determine the values \u200b\u200bof each of them and summarize the results.
How to determine the area of a room with uneven walls
If there is a room in which the walls look like polyhedrons or indirect disproportionate figures, the calculations are much more difficult. Measuring the perimeter in such a room is quite simple. You should use a tape measure and walk with it throughout the room, measuring each of the sections separately.
The area of the room is determined by drawing and designing the room. After the sketch is ready, we break the space in such a way as to get the maximum number of proportional figures in the form of a square, triangle or rectangle.
In order to determine the area of a segment that has the shape of a rectangle with identical edges, it is enough to measure the size of the legs, which are multiplied by each other and divided in half. That is, to determine the area of a triangular segment with legs of 0.5 and 0.9 m, the following calculations should be carried out:
0.5x0.9 / 2 \u003d 0.225 square meters.
How to calculate the area of a room in which there is a multi-level ceiling
The ceiling, on which there are ledges, is more difficult to calculate, but it is quite realistic. There are multi-tiered ceilings that are in the form of straight lines, their calculation is easy to carry out, but there are structures that require special care, since they consist of arcuate or wavy fragments for the calculation of which special efforts are required.
It is too long and costly to calculate each of the sections, especially since the result is not always the correct result. After all, the arcs designed on the ceiling can be arbitrary.
The easiest way to determine the area of the room is by the total area of \u200b\u200bthe floor. To do this, you must perform a series of actions:
1. Measure all straight wall sections.
It is preferable to take measurements closer to the ceiling, as the length of the wall above and below the room may differ.
2. Determine the floor area using the previously indicated methods.
3. On each of the vertical sections, measure their height and length and multiply these figures.
4. Add them to the total floor area.
Determination of the total area of the room
In order to answer the question of how to find out the area of \u200b\u200ba room in square meters, we suggest that you read the instructions that will help you complete this task:
1. Take care of cleaning the space near the walls.
The walls of the room should be freely accessible. Thus, the correctness and accuracy of the measurement will increase. If possible, it is better to free the entire room, since in carrying out certain calculations it will be necessary to measure the central sections.
2. Identify areas in the room that have the correct shape.
If the room looks like a rectangle, then it does not need to be divided. Otherwise, the room is divided into shapes in the form of squares, semicircles, trapezoids, triangles or rectangles.
3. Make a sketch of the room, so it will become easier to work.
Measurement of the area of the room must be carried out according to the sketch, on which all measurements are marked. Tip: In the absence of paper and if you need an urgent measurement, use the adhesive tape that is attached to each wall.
4. Length and width of the room, area.
Each wall should be measured in width and length preferably twice. In order not to measure the entire wall as a whole, it must be divided into several fragments, and as a result, the results obtained should be summarized.
In order to make sure that the calculation is correct, if there is free time, measurements are taken twice.
5. Determine the area of each of the plots:
- the area of a rectangle is equal to the multiplication of its length by its width;
- the area of a square is one of its sides in a square;
- the area of the triangle - the height and side, are multiplied among themselves and the resulting value is divided by two;
- The area of a circle is pi multiplied by the radius squared.
6. The areas of previously defined sections are added together.
Determining the minimum area of a room
1. Plots in the form of a rectangle.
Using a tape measure, the length and width of the plot are measured, they are multiplied together. Data are most often rounded to the nearest centimeter.
2. Triangle.
The area of a given area is determined by multiplying one side of the triangle by its height, that is, the line drawn from the top of the triangle, which divides it into two equal parts. The resulting value is doubled.
3. Circle or semicircle.
Radius definition. This value is squared, multiplied by the number Pi. In the presence of a semicircle, the value is divided into two.
In addition, there are special online calculators on the Internet that allow you to carry out all calculations quickly and efficiently. To work with them, it is enough to select the shape of a section of the room, measure it with a tape measure and enter the data. The program itself will carry out all the necessary calculations and determine the area.
Optimal room area
Each room has its own size, and during the planning of the house, this factor is taken into account in accordance with their purpose. The minimum value of the area of an ordinary living room is eight square meters.
The area of the common room or living room should be from 13 to 23 square meters. The bedroom should be located in the corner of the house, and not be a walk-through room.
The minimum height of the living space is 240 cm. It is not recommended to equip rooms with a height of more than 300 cm, since they are completely impractical, and a large amount of material investments will be required to heat them in winter.
Each room should be distinguished by the presence of natural light. At least 30% of all walls should be windows. Please note that it is preferable to install windows on the south side, since in winter, on the north side, they will provoke large heat losses.
If the living area of a house or apartment is from 15 to 55 square meters, then the minimum kitchen area should be 6 square meters. When planning a kitchen in buildings with a living area of more than 55 square meters, the kitchen should occupy at least a fifth of the entire house.
If the kitchen occupies more than 10 square meters, it is possible to use it as a dining room or a room for receiving guests. The minimum width of the hallway is 140 cm, it must also have natural light.
For a children's room, an area of \u200b\u200b10-15 square meters is enough. The smallest should be the bathroom and toilet. Their area is equal to 4-8 square meters.
It is impossible to repair the floor surface without knowing the exact floor area in a private household or apartment. The fact is that today the cost of building materials is quite high, and every property owner tries to save as much as possible on their purchase. Therefore, information on how to calculate the floor area will not be superfluous for someone who prefers to make repairs with his own hands.
Why you need to know the floor area
Before starting work, you should decide on the scope of activities, plan costs and calculate the amount of building materials. To do this, you will need the original data. For this reason, it is important to know how to calculate the floor area accurately. This is especially true for uneven surfaces and rooms with a non-standard layout.
There are other reasons when there is a need to accurately determine the dimensions of the floor surface:
- checking the quality of construction work;
- the need for redevelopment of the premises.
Determining the area of a rectangular room
Before you calculate the floor area, you should stock up on a calculator and a measuring tape. Most often there are rooms in the shape of a rectangle. To calculate their area, they use a formula known to everyone from school: S \u003d a x b, where a and b are the length and width. For example, a room has parameters of 3 and 4 meters, then the desired value will be 12 square meters. m.
In the event that the room has a fireplace or built-in furniture, then you need to find out their area and subtract from the total area. In the case of a major overhaul of the floor, all unnecessary in the room will have to be dismantled.
Calculation of the area of the room of the wrong layout
It is much more difficult to calculate the area of a room that has a polygonal shape. Often in brick houses in the layout there are niches, triangular recesses and rounded elements, as in the photo.
In this case, before calculating the quadrature of the floor, the layout of the room must be divided into separate zones. For example, if the room has an L-shaped layout, it should be divided into 2 rectangles, then calculate the area of \u200b\u200beach of them and add the results.
Finding the area of a triangular room
When another part of the room is not perpendicular to the main area, this means that there is also a triangle between the two rectangles, which has a right angle.
In this case, the area of the triangle is calculated by the formula: S \u003d (a x b): 2 and added to the grand total. For example, a \u003d 2, b \u003d 3, then S \u003d (2x3): 2 \u003d 3 m².
You can define the area in another way:
- First calculate the square of the rectangle.
- Determine the area of the beveled triangular corner.
- Subtract the area of the triangle from the quadrature of the rectangle.
In the case when the triangle does not have a right angle, then use the Heron formula S \u003d √p (p - a) (p - b) (p - c).
For example, its sides are 5, 6 and 7 meters, then the calculations are made as follows:
- Find out the semiperimeter of the triangle p = (5+6+7):2 = 9.
- Digital values are substituted into the Heron formula and the result is obtained: √ (9 x (9-7) x (9-6) x (9-5) \u003d 14.7 m².
The square of the premises is rounded
Often, a similar form is present at the windows in old houses or on balconies that are combined with rooms. First, calculate 1/2 of the protruding part of the circle and add to the area of the rectangle, applying the formula S = πR²: 2, in which:
R² is the radius of the circle squared.
How to calculate the area of the walls of a room
The procedure for calculating the area of \u200b\u200bwalls and floor is different. The fact is that before you calculate the quadrature of the floor, you should find out the length and width of the room, and to calculate the walls you will need to measure its height. Therefore, they first find out the perimeter of the room and multiply by the height of the ceilings.
For example, the floor parameters are 3 and 4 meters, and the height of the room is 3 meters. In this case, the perimeter of the walls will be equal to (3 + 4) x2 = 14 m, and their area S = 14x3 = 42 m².
In this case, one should not forget about the quadrature of the openings of windows and doors. Their area is subtracted after the completion of wall calculations. But on the other hand, they can be ignored and thus provide a certain supply of materials.
Proportions between floor and window area
According to SNiP 31-01-2003, the parameters of windows and their number should depend on the quadrature of the floor. So for residential multi-apartment buildings, the ratio between the areas of window openings and the floor surface will be from 1:5.5 to 1:8. As for the upper floors, a minimum proportion of 1:10 is allowed there.
For private households, this norm is regulated by SNiP 31-02-2001. According to this documentation, for every 8 "squares" of the floor surface, there must be at least one "square" of a source of natural light flux. On the attic floors, this proportion cannot be less than 1:10.
To ensure high-quality repairs, you need to find out in advance how to calculate the floor area and other necessary dimensions of the room. The preparatory stage also provides for the purchase of building materials and then during the repair process, costs will be minimized, since there will not be large residues and the cost of delivery will be inexpensive.
The manual method of calculating how to find out the floor area will take longer than when making calculations on an existing construction calculator, but it allows you to find out more accurate results.
Choose a tape measure or measuring tape. Choose a tape measure or measuring tape that has markings in centimeters (cm) or meters (m). This fixture will make it easier to calculate the area in square meters, since they were designed in the same measurement system.
- If you can find a tape measure in feet or inches, measure the area using the available units of measure, and then proceed to the step that describes how to convert other units of measure to square meters.
Measure the length of the area you have chosen. A square meter is a unit of measurement for the area or size of a two-dimensional object such as a floor or field. Measure the length of one side from one corner to the other and record the result.
- If the length is more than one meter, then count both meters and centimeters. For example, 2 meters 35 centimeters.
- If the object you are measuring is not a rectangle or square, then read the third section of this article - "Measuring the area of complex shapes."
If you cannot measure the length at a time, do it in stages. Unfold the tape measure and make a mark where it ended (for example, 1 meter or 25 centimeters), then unfold it again and start from the marked area. Repeat until you have measured the entire length. Then add all the measurements together.
Measure the width. Use the same tape measure to measure the width of an object. The measurement must be started by placing the tape measure at an angle of 90º with respect to the length of the object that you have already measured. That is, two lines of a square adjacent to each other. The resulting numbers also write down on paper.
- If the measured length is slightly less than one meter, then round to the nearest centimeter when you take measurements. For example, if the width is slightly larger than 1 meter 8 centimeters, then simply write "1 m. 8 cm." don't count millimeters.
Convert centimeters to meters. Usually, measurements cannot be made exactly in meters. You will get indicators in both meters and centimeters, for example, "2 meters 35 centimeters." 1 centimeter = 0.01 meters, so you can convert centimeters to meters by moving the decimal point 2 digits to the left. Here are some examples.
- 35cm=0.35m so 2m 35cm=2m+0.35m= 2.35m
- 8cm = 0.08m, so 1m 8cm = 1.08m
Multiply the length by the width. Once you convert all measurements to meters, multiply the length by the width and get the area of \u200b\u200bthe object being measured. Use a calculator if necessary. For instance:
- 2.35m x 1.08m = 2.538 square meters (m2).
Round up. If you get a lot of decimal places, for example, 2.538 square meters, then round up, for example, to 2.54 square meters. It is likely that you did not take measurements to the nearest millimeter, so the last figures will still not be accurate. In most cases, we round to the nearest centimeter (0.01m). If you need more accurate measurements, read this material.
- Every time you multiply two numbers with the same unit of measure (eg meters), the answer must be written in the same unit of measure (m 2 , or square meters).
Purchasing the necessary materials for repairing a room is a responsible matter. And sometimes the main thing is to decide on their quantity, and not just on quality and appearance. To purchase materials in exactly the amount you need, you will have to carefully measure the room. How to calculate square meters of the floor? Everything is quite simple, it is enough to understand the principle and remember school mathematics lessons.
Any repair cannot begin without accurate knowledge of the size of the room. To calculate the number of wallpapers or panels, you need to find out the dimensions and area of \u200b\u200bthe walls, to purchase a sufficient number of ceiling tiles, measurements are taken from the ceiling. Of course, for the purchase of flooring in the required volumes, you will also have to try and find out the value of the area of \u200b\u200bthe entire floor space.
With the removal of measurements from the premises and the determination of the area of \u200b\u200bthe base, every person who decides to independently start repairs is faced. If the owner of the premises turned to specialists for help, then he will not have to delve into anything - the masters will do everything themselves. However, many still decide to carry out repair work with their own hands. This allows you to significantly save money spent on repairs.
The main reasons for the need to determine the floor area are as follows:
- repair or primary laying of flooring;
- pouring fresh screed;
- arrangement of the lag system;
- floor painting;
- applying other building materials to the floor;
- determination of the size of living space when drawing up documents or buying / selling an apartment or house;
- determining the compliance of the premises with the room plan;
- selection of furniture according to dimensions;
- drawing up a room plan for further work;
- assessment of the cost of the work of specialists and other costs.
Basically, knowledge of the floor area is required in order to calculate the amount of building materials needed for finishing that will be used during work. For example, the volume of cement mixture for pouring the screed, the number of self-leveling floors or packs of laminate, etc.
On a note! In order to calculate the required amount of materials, you need to know not only the area of \u200b\u200bthe room by the floor, but also the area of one part of the material you have chosen. For example, lamellas or tiles.
Room area in square meters
Do not confuse area with perimeter. The area is the dimensions of the entire floor space, limited by a certain perimeter of the walls. And the perimeter is the sum of the lengths of all sides of the room. Knowing the perimeter is also necessary, but this value is calculated in order to calculate how much plinth will have to be purchased to finish the room.
What dimensions are needed for calculations?
So, what measurements will you have to take to determine the area of \u200b\u200bthe room? The answer is simple - everything that touches the perimeter of the room, and it does not matter whether the room is geometrically even or has a lot of niches and corners. Generally speaking, to calculate the area of any room, you will need its length and width.
What tools are used to calculate areas?
Various computer programs can be used to calculate the area of \u200b\u200bthe room, and various mathematical formulas for calculations are also used. But the dimensions of the sides of the geometric figure, which corresponds to the room, will have to be removed in any case.
Table. Tools for taking measurements of the room.
| Name | Recommendations |
|---|---|
| Necessary for recording received readings. If the readings are not recorded, then you can quickly get confused. Also, paper and writing utensils will be useful for drawing up a floor plan. |
| With its help, all dimensions are determined directly. The larger the room, the longer the tape measure will have to be purchased. You should not use a soft fabric centimeter tape, which cutters use - it is quite short and soft, so it will be inconvenient to take measurements and errors can be made. |
| Required for all mathematical operations. It is convenient in that it will reduce the risk of errors. |
| A handy device that allows you to quickly and accurately take measurements of any room. |
| May be needed to measure angles in a room. It is worth remembering that even seemingly right angles are not always so. And sometimes you need to know the exact size of the angle. |
Manual calculation on a piece of paper is convenient in that all parameters can be immediately measured on the spot and make the necessary adjustments. But it’s quite easy to make a mistake with the manual method of calculations, so it’s better to recalculate all the indicators once again.
On a note! It is better to measure the room once again if you are unsure of the readings than to end up buying an insufficient amount of material or purchasing it in excess.
To automatically calculate the area of the room, it is convenient to use various graphic editors. It can be AutoCAD, ArchiCAD or SketchUP. They create a figure according to the shape of the room, the dimensions of all its sides are indicated when creating the layout. The area of the room will be given by the program automatically and with high accuracy (up to centimeters and millimeters). Everything will depend on the accuracy of the measurements taken. The use of these programs is especially recommended if it is necessary to calculate the area of a room that is complex in its geometry. The disadvantage of this method is the need for at least a superficial study of programs, as well as the use of computer technology.
How to calculate floor area?
The main rule when measuring the parameters of the premises is to take measurements along one line. For example, along the wall. However, the tape measure should be placed on the floor, as the walls may have some curvature. If the room is filled with bulky things, then measurements can be taken not along the wall, but slightly away from it. The main thing is to make sure that the roulette tape lies flat, does not bend, otherwise there may be a large error.
Calculating the area of a rectangular room
A room that does not have any, even small, ledges and niches, or, simply put, is rectangular - the easiest option for taking measurements and calculating area values. Here it is enough to recall the simplest formula from a mathematics course - how the area of \u200b\u200bsuch a figure as a rectangle is calculated. To do this, you need to measure only the width (A) and the length of the room (B). Thus, we get that S (area) will be equal to the value that will be obtained by multiplying the two indicators A and B.
On a note! If the figure is not a whole number, then it must be rounded up. For example, 4.357 is rounded up to 4.5 m2.
All measurements are given in meters. Centimeters are indicated after the decimal point. For example, the length of the wall turned out to be 376 cm, then it turns out (in 1 m - 100 cm) that the length of this wall will be 3 m 76 cm.
