The word “weaving” is widely used in informal communication between people, especially those associated with land plots. Yes, yes, what gardener doesn’t know how many acres of land are on his plot? The old generation remembers exactly and by heart about their three or six hundred square meters!
And although in official land documents it is required to indicate the area of plots only in hectares, especially when buying and selling, it is still more common for people to hear and count land for a garden in acres.
To interact with cadastral authorities, you have to strain and recalculate the area of the plot in hectares (ha). In this material, we propose to understand the terminology and units of land measurement, find out what a “weave” actually is and what is its relationship to a hectare.
How to measure the area of a plot of land with a simple shape?
It is correct to start measuring by measuring the sides of the area. Having hammered pegs into the corners of the area, using a tape measure, take accurate measurements of their length and width. If the area is of the correct geometric shape, then only two sides are needed - length and width. It is better to write down the measurement results in a notepad or enter them into a computer.
But if your site turns out to be asymmetrical, then you need to take measurements of all four of its sides and angles in degrees, or the length of the diagonals - also for recording.
If your vegetable garden is of irregular shape (NOT a square or NOT a rectangular plot), then the method of measuring a plot of land is a little more complicated than multiplying the length and width, but it is quite possible for an ordinary person without special education.
The history of the concept of “1 hundred square meters”
In our country, small plots are usually measured in hundreds. However, this was not always the case. In pre-revolutionary Russia, instead of the term sotka, the quantity - are was used. But these quantities only differ in names; in size, 1 weave corresponds to 1 are. Today this measure of area is no longer used; mention of it can now be found either in fiction or in old documents. Actually, the concept of “weaving” appeared only in Soviet times, during the period when it was customary to distribute land for summer cottages for use by the population. It was believed that 4-6 acres was enough for a Soviet citizen to build a small house and plant gardening and vegetable crops for personal needs. Therefore, today you can often find advertisements for the sale of land in SNT with an area of 6 acres.
To designate large areas of agricultural land, on the contrary, it is more convenient to use hectares. The cadastral land plan and documentation related to the registration of plots are drawn up using a measure to calculate areas in hectares. For any Russian, it is more common to perceive the length and width of the land in meters - this makes it easier to calculate the area in square meters. m. Therefore, you need to be able to convert square meters to both hundreds and hectares.

How to determine the size of a plot in square meters
To make the calculation as accurate as possible, you will need a tape measure, several pegs and a notepad to record the measurement results. The entire course of the required calculation follows the laws of the school geometry course, which states that to accurately determine the area of a rectangular figure, you should multiply its width by its length, for example:
S=A*B
Where
- A—length, m;
- B—width, m;
- S—area, m2;
For example, if the length of your plot of land is 70 meters and the width is 40 meters, then the area can be calculated as S = 70m * 40m = 2800 m2, that is, in this case, the area of your land is 2,800 square meters.
Where to find out about regulations for a specific region
Each region has its own rules, since the limits are set by the local government. Such values are fixed by the urban planning regulations of the Land Use and Development Rules (LRU) of a certain area.
The local administration will tell you what the maximum area and the minimum area of the plot for individual housing construction established on its territory are and for other cases.
Regional laws No. 63/2003-OZ, 83-OZ and 405-53 on the territory of the Moscow and Leningrad regions, St. Petersburg, respectively, establish the following minimum and maximum sizes of plots intended for residential construction:
- For the Moscow region, the law does not provide for a minimum plot size for building a house, and similarly, a maximum. Those. in fact, for such purposes, plots of land are not provided to citizens for construction.
- For St. Petersburg, the minimum permissible area of a plot that can be issued on the right of ownership to a citizen for private individual residential development is contained in the urban planning regulations; for a number of territories in respect of which the regulations do not apply, a minimum of 3 acres is established.
- In the Leningrad region, the maximum that can be claimed is 25 acres, a minimum of 6 acres in the cities of the region, 10 acres in the countryside.
How to convert meters to hundreds
Considering that 1 hundred square meters is equal to 100 m2, we go the opposite way to convert the data from meters to hundred square meters. This will allow you to obtain correct results of measuring the area of a given land plot. When calculating the number of square meters in a hundred square meters, you need to divide the resulting result by 100, for example:
- plot area - 1000 m2;
- 1000 m2 divided by 100;
- number of acres - 10
If your plot has an irregular geometric shape, but you have correctly calculated its area in square meters, the method for calculating the size in acres remains the same. Large areas are usually measured in hectares, each consisting of 10,000 square meters or 100 acres.
Methods for calculating the dimensions of the land along the perimeter
Another question deserves our attention: “one hundred square meters of land is how many meters around the perimeter,” and what methods are used to measure the site. The lengths of the sides can be whatever you want. It all depends on the form of land tenure. In practice, there are several simple ways to calculate them along the perimeter. Moreover, you can find out the size of the land on your own, or by using the services of a specialist from a geodetic organization. In the second case, a surveyor, using professional equipment, will determine the exact boundaries of your land plot or, as they say, will carry out land surveying.

Self-measurement methods:
- the simplest of them is to calculate the lengths of all sides by measuring them in steps at right angles. It is easy to imagine a distance of one meter. It is approximately equal to a very long stride of an adult. This means that by measuring a little more than 10 steps in one direction and the opposite, we get 1 hundred square meters. This method, of course, does not give an accurate result. When building a house, it is better to turn to professionals;
- with the second method, you need to fix pegs along the boundaries of the area and connect them with a rope. Next, use a regular construction tape to measure the length of the rope on all sides.

Many people are interested in how many meters around the perimeter - 6 acres, this again depends on the land we are dealing with. If it is rectangular, then 30 by 20, or 40 by 15 meters. According to the standards, for the construction of a residential building for one family, an area corresponding to one hundred square meters or 100 square meters is sufficient. m.. If there are 6 acres, then there will be space on the site for the construction of a small bathhouse, a separate bathroom and outbuildings. If you arrange everything compactly, then perhaps there will be room left to set up beds and plant several fruit trees.

Calculation of land area online using a calculator
Today there are quite a few services and online calculators on the network that allow you to calculate the area of a land plot; just use one of the search engines, for example Yandex.
Keep in mind that the online land area calculator will need the exact measurements of all sides of the land in meters for its algorithm to accurately calculate the area of your land.
Laws
Fundamental issues related to land, including issues of maximum sizes of plots for individual housing construction, are regulated at the federal level by the domestic land and civil codes.
Issues relating to the establishment of maximum and minimum plot sizes are regulated in more detail in local acts of each individual region, but in such a way that their norms do not conflict with federal land legislation.
What regulatory framework will regulate the issuance of a particular plot depends primarily on its legal affiliation. Plots owned by the state are provided purely on the basis of federal legislation, while plots owned by a municipality are regulated by the regional one, to the extent and to the extent that they do not contradict federal legislation.
How to calculate the area of a plot of complex shape?
An irregularly shaped area is more difficult to calculate, and the dimensions of the sides alone will not be enough to calculate the area of a complexly shaped area. Here you will need to know the dimensions of all sides of the garden, and the size of the diagonals. It’s a little easier if one of the corners of the plot is 90 degrees.
Here is an example of calculating acres of land for a complex-shaped dacha plot:
Dimensions of the sides of the land plot, in meters
- Side AB = 69 meters,
- Side BC = 46 meters,
- CD side = 87 meters,
- Side DA = 35 meters,
- Lower left corner is straight (90 degrees)
Using these data, you can determine the lengths of the diagonals BD and AC, and calculate the area of the plot = 3035 square meters (or 30.35 acres).
Measurement methods
The area of land can be determined in three main ways:
- analytical;
- graphic;
- mechanical.
Analytical
It consists in determining the area of the site based on the coordinates of the characteristic points of its boundaries. This method uses analytical geometry formulas.
In accordance with them, the area of the polygon S is determined by the formula :
S= 0.5*∑(Xi*(Yi+1-Yi-1) , where:
- Xi and Yi are the coordinates of the i-th characteristic point of the area, which has the form of a polygon.
- i is the serial number of the characteristic point. This parameter varies from 1 to n, and n is the number of characteristic points.
If the plot has the shape of a quadrangle, then the area calculation is calculated using the above formula with n=4.
If the area has the shape of a trapezoid, then its area is found using the formula:
St=0.5*(a+b)*h , where:
- a and b are the bases of the figure;
- h – height of the trapezoid.
When calculating an irregularly shaped quadrilateral, you first need to determine the value of the semi-perimeter p:
p=0.5(a+B+c+d) , where: a,b,c,d are the dimensions of the sides.
Then Su will be equal to:
Sy=√(pa)(pb)(pc)(pd).
Graphic
To calculate the area using this method, a plot of land with a complex shape shown on the plan is divided into simple sections (rectangles, triangles, trapezoids), then the areas of these figures are calculated and added together. The accuracy of the graphical method is determined by the accuracy of the graphical measurement on the plan . This method is convenient to use if the number of characteristic points is small.
If the area has a curved shape, special palettes are used.
Mechanical
Used for a large area with complex boundaries . To do this, use a planimeter, which is a device that allows you to determine the area of a flat figure by tracing its outline.
The accuracy of this method depends on the size of the site and the properties of the plan.
Attention! The area of a plot placed in the real estate cadastre can be determined using an online service called “Public Cadastral Map” by address or cadastral number.
