Types and types of lumber, its features and scope
Before calculating how many boards are in a cube, you should decide on the type of material that will be used in the construction process or a specific object. Features of processing and appearance of lumber determine its possible area of use. We offer you to get acquainted with the most common types and their main purpose.
Edged timber
The beam has a square or rectangular cross section. Its linear parameters usually exceed 100 mm. For manufacturing, the core of the tree is used, which is processed from four sides. The result is lumber of the desired geometry, but without surface finishing. The standard length of the product is usually 6 meters. When deciding how to calculate the cubature, this linear parameter must be taken into account.
Demanded for construction. Given the quality of the surface treatment, in the future an additional one will be required.
edged timber
Planed timber
For the manufacture of planed timber, solid wood is used. The choice is made in favor of logs that do not have defects, with transverse dimensions of more than 150 mm. The most widely used timber with dimensions of 100 × 100; 100×150; 150×150; 150×200 mm. The last standard size is most often made to order and has a higher cost than analogues with smaller geometric parameters.
Planed timber is widely used in the construction and installation of internal partitions. The high quality of the surface makes it possible to refuse to perform additional work.

planed block
The cross-sectional shape may be different. Manufacturers offer a bar with a square, rectangular or other sectional shape. The requirements for the aspect ratio of the finished product are established. Their width cannot be twice the thickness. The last linear dimension can reach 100 mm.
Planed products subjected to special processing have a smooth surface. They are widely used in the construction of various, the appearance of which is subject to increased requirements. Actively used in industry.
Edged bar
Unlike planed, edged timber is not subjected to additional finishing. This greatly reduces its cost. It is widely used in the construction and installation of structures intended for the installation of facing material.
Edged board
For such lumber, the thickness can reach 100 mm, and the transverse dimensions in this case should be at least twice as large. During the production process, wood is processed from all sides. As a result, it is possible to provide the necessary geometric accuracy and relative evenness of the surface.
Edged material is used when performing various types of work. The inch board is especially popular, the size of which is numerically equal to 1 inch (25 mm). This thickness is in demand when arranging battens, floors and many other surfaces.
How to calculate a cube? It is enough to multiply the linear parameters to find the volume of one product. Then one cube is divided by the resulting value. This will allow you to find out how many products will be in a cubic meter. Knowing the required number of products and how many of them are in a cube, it is easy to calculate the order volume.
edged board
Floor board
Designed specifically for the device. It has a width of 85÷140 mm with a thickness of 27÷45 mm. The choice of linear parameters of the product is made taking into account the subsequent operational load. An online calculator of boards in a cube will allow you to calculate how much material you need to purchase for a floor covering of a certain area.

Unedged materials
Unlike edged material, such lumber has a lower cost, since there are partially sawn or unsawn edges (wane) on its surface. Because of this, it is most often used in the manufacture or construction of draft surfaces.
How many boards in a cube: a table with standard sizes
Knowing how many square meters are required, how many boards will be in a cube, depends on the linear dimensions of the selected material. Using special reference books (cubes), you can find the desired amount from the tables without tedious calculations.
How many boards in a cubic meter: the table will allow you to find out without calculation
Reference tables contain information data for lumber of various lengths. Before you find out from the table how many boards are in a cubic meter, you should check all linear parameters, and not just the width and thickness.
The most popular are reference tables for boards with 4 or 6. So, if we talk about how many edged boards 25 by 100 mm in size will be in a cube, you should definitely specify the length. Four-meter - 100 pieces, six-meter - 66 (66.6). Based on this, it is determined how many cubes of lumber are required.
Advice! If it is difficult to find reference tables, use the cubic meters calculator, which will help you perform the necessary calculation in a split second.
Having determined the amount according to the table, it is worth finding out how much the cube of the board weighs. To do this, you need to know the moisture content of the material. To find the answer to the question, you need to multiply the density by the volume, expressed in cubes.
The basic procedure for calculating the number of boards in a cubic meter
Before moving on to basic calculations and learning how to calculate a cube, you should pay attention to the unit of measurement. For timber, the unit of volume is the cubic meter. Often, cubic meters, cubic meters or cubic meters are used as a conventional designation.
Attention! One cubic meter is numerically equal to the volume of a cube whose edges are 1 meter long.
V = L×h×b , where
- V - the desired volume of the cube, m³;
- L – product length, m;
- h – height/thickness of the material, m;
- b - width, m.
Attention! All linear parameters must be expressed in meters. If dimensions are given in millimeters, each original value must be multiplied by 0.001 to convert to meters.
With the same number of square meters, how many products will be in a cubic meter will depend on the chosen thickness. If the height of the material used is large, then, according to the calculations in the cube, a smaller value will be obtained. By reducing the thickness of the board, you can increase the number of purchased products.
When determining how many boards are needed, it is necessary to take into account the degree of processing of the material, the grade and type of wood that was used for production. For edged and unedged lumber, the calculation will be slightly different. The calculation should be adjusted to take into account the usable area.
When calculating how much trimming material is needed, you should:
- Determine the linear dimensions of one board;
- Find the volume of one product;
- Divide 1 (cube) by the volume of one board to figure out how much will be in one cube. According to the calculations, it may not be an integer value.
To find out how much unedged board you need, you have to take measurements at several points. After that, the desired linear size is averaged, and the found value is subsequently used when performing calculations.
If there are a lot of boards, and their linear dimensions differ, proceeding to the calculations, they sort by length and width. It is desirable that the linear parameters differ by a maximum of 10 cm. Then the height and length of the formed stack are measured. Height is measured in the middle. The result obtained is multiplied by a correction factor, the numerical value of which is 0.07 ÷ 0.09 units. Its value can be found in the cubature reference book.

Many, when building a house or a bath, are faced with the need to calculate how much lumber is required for work. Determining how much board or timber you need is simple. But the price of lumber is usually indicated per cubic meter, and in this case it will be more convenient to use a special program for calculations. With the help of our website, knowing the length, width and thickness of the board, as well as their number in pieces, you can calculate how many cubic meters of lumber you will need and how much one cubic meter or one board will cost.
Scope of application
Lumber is so called because it is obtained by sawing the trunk of a tree. Lumber is used for construction, furniture manufacturing, various containers and other products. Today, this type of building materials is the most popular. The wood from which lumber is made is an excellent heat-insulating material, maintains a stable humidity and does not require special treatment and care, which makes it especially convenient.Types of lumber
Timber includes timber, edged boards, unedged boards, building slats. The beam is a log processed from all sides. In the cut, it has a square or rectangular section. The timber is most widely used in the construction of houses, baths and floor structures.The edged board is a versatile lumber that is actively used both in construction work outside the building and in the design of the interior space. Edged board in cross section is an elongated rectangle. An unedged board differs from an edged board in that its edges are not cut off, so that a layer of the bark of the tree from which this board was cut remains visible. A building rail or bar is a bar with a smaller section than a regular one and is widely used in construction.
Lumber is classified according to the type of wood from which it is made. They are made from coniferous trees such as pine, spruce and larch. And from hardwoods such as oak and beech, birch, aspen.
Lumber is also distinguished by moisture content. They are divided into raw with a moisture level of more than 22 percent and dry with a moisture content below 22 percent. The former are used for construction work, and the latter for the manufacture of furniture.
There are also several varieties of lumber. The choice of grade depends on the application. So, for furniture, materials of the highest grade are used. For joinery and moldings, grade 1 lumber is suitable, and grade 2 and 3 are used exclusively as a building board. Lumber, if not used for a long time, must be protected from moisture. This can lead to their deterioration. It is not recommended to store lumber stacked on top of each other. There must be spacers between the layers of beams or boards.

What is a cubic meter of edged board
How many edged boards in one cube - Photo
Edged board- lumber with cleanly cut edges, without bark residues. The width of the edged board exceeds the thickness at least twice.
Since the fee is charged for the volume in cubic meters, we recall the geometric formula for its definition:
W * H * D = volume.
Everything is in meters.
To find out how many boards are in one cube:
1 / (W * H * D) = number of boards in 1m3 (cube)
where, W- Width, AT- Height, D- Length
Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m

When buying lumber in small quantities, you can get confused with decimal places, namely with rounding. An experienced seller will round the resulting number to the 3rd decimal place. The experienced buyer will round up GOST y - up to 0.000001 cubic meters and remind the seller that up to 0.001 cubic meters. meters are rounded only a batch of boards. The most common quantity - from several boards to 2-4 cubic meters - does not make up a batch. In order not to offend either one or the other, they are rounded to 4 decimal places.
Then the resulting volume is multiplied by the cost of 1 m3 (cube). And here the number of decimal places can significantly affect costs.
1 edged board 32 mm thick, 200 mm wide and 6 m long(32X200X6000) has volume
- 0.032 * 0.2 * 6 = 0.0384 cubes
30 boards will have volume
- 0.0384 * 30 = 1.152 cubes
If the seller rounds the volume of 1 board to 0.04 cubic meters, he will additionally receive income:
- 0.04 * 30 \u003d 1.2 cubes
- 1.2 - 1.152 = 0.048 cubes
Selling these 0.048 "air" cubes makes the buyer's wallet easier
The cost may vary depending on the type of wood. Grading decreases with a decrease in quality: the presence of wood defects and deviations from standard sizes. If the floorboard has a curvature, narrower or thinner than the standard by 3-5 mm, it will not work completely. Visual inspection of the lumber is just as important as accurate sizing.
Edged board area covered
To find out how much lumber you need, the calculation of the board in a cube will help you. The above formula is based on the definition of area
W * D = area.
Having calculated the covered area, it remains to multiply it by the desired thickness of the board
W * D * 0.022; 0.025; 0.032; 0.04m and so on.
It remains to see how many boards are in one cube, and determine the required number. Just in case, print or memorize the table above.
You also need to take into account the future cutting of the material.The floorboard and sheathing board "lining" have an overlapping tongue, which is taken into account in the cubature, but is not included in the area to be covered. A couple of boards are needed have in reserve .
Determining the volume of unedged boards
How many unedged boards are in one cubic meter - Photo
Unedged board, that is, not having a rectangular section along the entire length, is much cheaper and is widely used for the installation of various kinds of rough battens, temporary fences.
It is important to understand that the top and bottom of such a board must be sawn along the entire length. If one face is not propylene, then this is already croaker. The definition of the cubic capacity of such lumber differs precisely in that it does not have the correct geometric shape.
The current standards establish several ways to account for unedged material, and it is practically impossible to calculate exactly how many boards are in 1 cube.
- Batch.
- Piece by piece.
- Sampling method.
In batch In this case, the boards are tightly packed into a bag of the correct shape with further measurement. Further calculation is carried out according to the standard formula for determining the volume. using various coefficients.
Piece measurement made according to average measurements of height and width. The largest and smallest dimensions in meters are added and divided in half.
(Wmax + Wmin) / 2 * (Hmax + Hmin) / 2 * L = volume, m3
where, W- Width, AT- Height, D- Length
If it is visually visible that the wood is fresh and, accordingly, damp (humidity above 20%), then the seller is obliged to reduce the total volume by multiplying the received cubic capacity by the coefficient:
- 0,96 for softwood
- 0,95 for deciduous.
Sampling method used to determine the volume of a large batch of unedged lumber. When loading, for example, into the body of a vehicle, every fifth, tenth or twentieth board is measured using the second method.
The resulting volume is multiplied by five, ten, twenty. Loading continues to the next control board. The selection of control boards in a separate foot is also practiced. The calculation is made after the loading is completed.

W * T * D = volume of timber, m3.
To find out how much timber is in one cube
1 / (W * T * D) = amount of timber in 1 m3 (cube)
where, W- Width, T- thickness, D- Length
Translation: 1mm=0.001m, 10mm=0.01m, 100mm=0.1m
When buying a beam, the volume must be determined by the piece, since the beam is laid with spacers in the stack. The measurements of such a stack and the calculation of the cubature according to the above formula invariably lead to a significant overestimation of the volume.
Length of 1 cube of timber (and any edged lumber) in meters is determined by dividing the unit by thickness and width. For example, you need to find out how much timber is in one cube - a face of 180 mm.
1 / (0.18 * 0.18) = 30 meters 87 cm.
1 meter of such a beam will have the following volume.
0.18 * 0.18 * 1 = 0.0324 m3.
These calculations may be needed when determining the cost of funds and material.
Construction log volume: how many logs are in one cube?
How many logs in one cube: calculation - Photo
Log buildings are and will be relevant. The determination of the volume of round material depends on the method of its production.
- Construction log of manual debarking.
- Construction log, rounded on special machines.
The section of the barrel for trimming by hand has the shape of a slightly truncated cone, so the cylinder volume formula is used, but with some peculiarities.
3.14 * r2 * L = log volume, m3
Here
r- average radius, calculated as (r1+r2)/2, r1 is the radius from one end of the log, r2 is the radius from the other end of the log.
L- log length.
3,14
- constant "Pi".
The rounded log has, of course, a cylindrical shape and is calculated according to the above formula. But here the radius is measured at any end once. Determining the number of logs in 1 cube is determined similarly to a bar.
1 / (3.14*r2 * L) = Number of logs in 1m3 (cube)
Blanks for construction logs are measured in the same way.
The radius (diameter divided in half) is measured without taking into account the thickness of the tree bark. In practice, manual calculations are not carried out. They use special tables summarized in a cubature book. They are also available in electronic form.
In conclusion, it should be noted that lumber for critical work, standard in size, wood species and humidity, should be purchased at large sites. A small producer, as a rule, is not allowed there due to the lack of appropriate control over the quality of their products.
In order not to waste time in the process waiting for the delivery of lumber and the problem of shortages, you should immediately calculate the required quantity and place an order with some margin. Initially, it is worth knowing how many boards are in a cube. The table given in the regulatory documents will help you quickly determine the desired value. You can also use the cubic meters calculator developed by our team, with which it is easy to determine the number of a specific size online. We suggest that you familiarize yourself with the possible methods to make it easier to choose the best one.
Everything starts with choosing the right material. Manufacturers offer lumber of different sizes, shapes and degrees of processing. Each of these indicators can have a significant impact on the cost. In order not to overpay, we suggest that you familiarize yourself with the most popular types of lumber, as well as their possible area of \u200b\u200buse.
Edged timber
The most popular type, widely used at the stage and repair work. Can have different sizes in all directions. Made from solid wood. All facets of the material are processed.
To find out how much will be in the cube, you need to know the sawing parameters. By multiplying the length by the cross-sectional area, you can find the volume of one product. To determine the amount of timber in a cube, it will be necessary to find the reciprocal of the volume found, expressed in meters. If it is initially known how much is required, the volume of one product will need to be multiplied by the required quantity. In more detail, how to calculate the cubic capacity, we will tell further.
Attention! Edged material has a natural moisture content. In reference tables, you can find the numerical value of moisture for different woods.
Planed timber
Lumber of this type in the manufacturing process must be dried. This affects the dimensions and weight of the finished lumber, as well as its service life. When determining how much a board cube weighs, this factor must be taken into account.
Planed timber has a high-quality surface that can be used in industry. Its sides in cross section are 1 to 2.
planed block
According to its characteristics, the bar is similar to the bar. The difference, according to regulatory documents, lies in the geometric parameters. If the width of the product is a maximum of 100 mm - this is a bar. Otherwise, we are talking about a beam.
Edged bar
Lumber with natural moisture content. It is similar in characteristics to a bar, but has smaller dimensions. When choosing, you should pay attention to:
- What kind of wood was it made from?
- how long did it take to dry?
- for what design is purchased.
Edged board
It is made from wood of natural moisture. It has a width twice the thickness in cross section. This significantly reduces the bearing capacity compared to timber. Most often used when performing construction work inside a building: when installing, flooring, walls. Suitable for the construction of a fence, outbuildings. The most popular board is an inch, the dimensions of which can withstand a significant operational load.
Floor board
Timber with a purpose. Manufacturers offer several types of floorboards:
- Parquet, characterized by high quality, we provide a three-layer structure;
- , combining the characteristics of natural wood and high-quality polymer;
- Usual made entirely of natural wood. Appropriate option for the device.
Attention! Choose a material that is thick enough for the specific service load.
Knowing how many square meters are laid, and how many boards are in a cube, you can calculate the thickness of the laid material.
Unedged materials
During the production process, such material is not processed from all sides. As a result, the finished product has two wide longitudinally placed plates and unsawn sidewalls. It is in demand in the construction of premises for various purposes, formwork, decking, as well as in the performance of various non-responsible construction works.
Before you count the cube, do not rush to look for the appropriate formulas. If you do not want to perform time-consuming calculations, reference tables will come to the rescue. How many boards in a cubic meter can be found with their help in a matter of minutes.
How many boards in a cubic meter according to the table
To begin with, it is worth noting that the dimensions of lumber are standardized. Using the regulatory documents, it is easy to find out how many boards are in a cube. To do this, you need to decide what size material will be used in the construction work.
If you could not figure out how to use the tables, you can use the online board calculator in the cube, or do the calculation yourself.
The basic procedure for calculating the number of boards in a cubic meter
Before proceeding with the calculation, it is worth knowing how to calculate a cubic meter. Such a volume will be numerically equal to a cube, each side of which is equal to a meter. To find the desired value, it is necessary to multiply the linear dimensions of the figure among themselves.
To begin with, the volume of one product is determined. If we are talking about an edged board, we multiply the linear dimensions of the board: length by thickness and width. If they are given in millimeters (mm), be sure to convert to meters. Otherwise, in the future it will be possible to get confused in the dimension.
After the cubature of one board is found, the calculation procedure depends on what initial data is. If you need to calculate the number of products in a cube, we find the reciprocal of the value found. In other words, when calculating the unit (1 cube), we divide by the calculated value. The resulting value should be rounded up to a larger integer.
If the material is purchased for a specific surface, you will need to know the dimensions of the room in order to calculate the quadrature of the room. To determine the required amount of lumber, cubic meters are converted into squares. To find out how many square meters are in a cubic meter, you need to divide the cube by the thickness (height) of the selected material.
If you are afraid of making a mistake when calculating the required amount, you should calculate the board in a cube on a calculator. A special program using standard formulas will allow you to determine the desired value much faster compared to independent calculations.
