Any construction or renovation work with wood requires painstaking calculation required quantity this building material. How to correctly calculate how much to buy of this material so as not to spend extra money and have enough for everything planned? Below is the formula and rules for calculating cubic meters of wood, which will help eliminate even the slightest errors!
What types of lumber are there?
Perhaps every person understands what lumber is. This is a tree that has already been sawn using special equipment.
The process of preparing lumber is always the same:
- Timber (round timber, i.e. logs) is brought to the sawmill;
- Next, this primary timber is sorted according to the directions of subsequent processing in order to ultimately obtain building material from wood of the required size (length) and area cross section(width + thickness).
You should know that timber and any type of lumber will be measured in cubic meters. According to construction and mathematical standards, a cubic meter is a volumetric square, the length, width and height of which is taken to be one meter.
In order to accurately determine whether there are enough wood building materials for a specific construction task, it is necessary to take into account the dimensions of the resulting edged board and the features of its primary wood processing.
Edged timber
This is the most popular lumber for construction or renovation, which can be of various lengths and cross-sectional sizes. If you know these cutting parameters, it is easy to find the number of boards in a cube.
For example, we received 25 boards 50 x 150 x 6000 mm. To calculate how many cubes this is, you can use a special table. There are only three columns here, according to the readings of which it is easy to calculate how many boards are in one cube. Since we have 25 boards, it’s easy to find out what cubic footage it is: divide 25 by the resulting value (how many boards are in 1 cube in a table of 6 meters).
Planed timber
Unlike edged timber, which has natural humidity, the planed timber is qualitatively dried. As a result of drying the timber, its volume and weight change slightly (decreases):
- If used in construction undried wood lumber, then when they dry, the surface may change its shape (the beam twisted or bent).
- The quality and wear resistance of the structure as a whole will depend on how much the building material weighs.
Another difference between planed timber and other types of lumber is considered to be a strict pattern in the original dimensions: the cross-sectional length of the timber should not exceed 2 times the width.
Planed block
According to construction GOSTs, there is a certain indicator that distinguishes timber from timber. This is the width of the section: if this parameter is more than 100 mm, then we have a beam, and if the width of the section is less than (or equal to) 100 mm, we are dealing with a beam.
Edged block
Edged timber (by analogy with edged timber) is freshly cut (or without proper drying) lumber.
The difference between edged or planed timber/timber is almost arbitrary, because You can change the width of the material by 2–3 cm (and therefore change the status of this material) on a sawmill without any problems.
Construction professionals choose to intended use timber, considering only 3 signs:
- The type of wood from which the timber is made;
- Drying time for this log;
- Peculiarities building structure(weight load), for the construction of which building materials are selected.
Edged board
This is a type of lumber with certain dimensions: the width should be 2 times greater than the thickness of the section. The load-bearing capacity of such building materials is less than that of timber.
Because their purpose is appropriate:
- Interior work (floor, roof, walls);
- Exterior improvements (fences, siding, construction of outbuildings, etc.).
Floor board
According to dimensions and intended purpose, there are different kinds floorboard (or lining).
Today the market building materials offers the following types of lining that copes well with covering any surface:
- Parquet - the extremely high quality and practical properties of this type of flooring are ensured by an internal structure of 3 layers: spruce, coniferous wood fiber and decorative fruit trees, ash, oak.
- Terrace - consists of natural wood+ some polymers. It is characterized by high tolerance to humidity, temperature fluctuations, and light.
- Sexual normal is pure wood material. Pine linings are used for arranging floors, walls, and ceiling coverings in residential premises. Linings made from aspen or linden are ideal for a bathhouse; larch linings are used for arranging street buildings (gazebos, terraces, etc.).
Based on quality, lumber for flooring is further divided into classes:
- Higher (or selected) is used only for elite buildings with extremely high wear resistance and reliability;
- The first and second are applicable for the construction of ordinary housing;
- The fourth is exclusively suitable for outbuildings.
How to measure
Calculating a sufficient amount of lumber is a responsible task. To calculate how many pieces should be purchased to carry out repairs on a specific floor or wall area, you should know the cubic footage of these lumber.
The task is not difficult, but pedantic, and begins with calculations on one board:
- The width, length and thickness of a unit of lumber are indicated in millimeters, which should be converted into meters;
- Multiply the resulting values (width x length x thickness) - this is the cubic footage of the board/beam.
Now, in order to estimate how many such boards/beams are in a cube, you need to divide 1 m 3 by the resulting product of the external dimensions of the building material and round to the nearest whole value. This will be the desired result.
How many boards in a cube: timber table
In order not to waste time on measurements/calculations, you can use a ready-made table. Here, based on the known dimensions of the timber, it is easy to calculate how much timber is in 1 cube and what is the volume of one timber.
| Beam size (mm) | Number of beams 6 m long in 1 m 3 lumber | Volume of 1 beam 6 m long |
| 100 x 100 | 16,6 | 0,06 |
| 100 x 150 | 11,1 | 0,09 |
| 100 x 200 | 8,3 | 0,12 |
| 150 x 150 | 7,4 | 0, 135 |
| 150 x 200 | 5,5 | 0,18 |
| 150 x 300 | 3,7 | 0,27 |
| 200 x 200 | 4,1 | 0,24 |
How many boards are in 1 cube: board table
There is a similar table for boards: knowing in advance (or having measured yourself) the original dimensions, it is very easy to find out the volume of a unit of this building material and how many boards of that size are in the cube.
| Board size (mm) | Number of boards 6 m long in 1 m 3 lumber | Volume of 1 board 6 m long (m 3) |
| 25 x 100 | 66,6 | 0,015 |
| 25 x 150 | 44,4 | 0,022 |
| 25 x 200 | 33,3 | 0,03 |
| 40 x 100 | 62,5 | 0,024 |
| 40 x 150 | 41,6 | 0,036 |
| 40 x 200 | 31,2 | 0,048 |
| 50 x 50 | 67 | 0, 015 |
| 50 x 100 | 33,3 | 0,03 |
| 50 x 150 | 22,2 | 0,045 |
| 50 x 200 | 16,6 | 0,06 |
| 50 x 250 | 13,30 | 0, 075 |
Formula for calculating a board in a cube in squares
To calculate surface area, only two indicators are used: length and width. Therefore, in order to calculate the required amount of lumber for work, the cubic capacity of lumber should be converted to quadrature and compared with the surface area.
It's easy to do: 1 m 3 divided by the thickness of the selected unit of building material.
Formula for calculating a board in a cube in pieces
To determine how many boards given size in 1 cubic meter, should:
1 m 3 / board volume (i.e. length x width x thickness)
Formula for calculating the volume of a board
Volume is a three-dimensional quantity. To calculate the volume of a board, take the product of width, thickness and length. But the situation becomes simpler if you take a meter-long beam or board. In this case, we multiply only the remaining two quantities: thickness and width of the section.
How many boards are there in a cubic meter? Memo to the developer
It faces every developer. For a person who does the work with his own hands, calculating the number of boards, timber or bricks determines the cost of building materials. A person who has hired workers and left it to professionals to decide how much and what needs to be purchased in order to erect a building will be interested in checking the master’s calculations with his own calculations. Let's give various ways calculation of lumber in one cube. You will need a construction tape and a pencil with a calculator.
Method 1: Mathematical calculations and formulas
Calculation of lumber per cubic meter of space can be done using known (with school course mathematics) formulas. The volume of a rectangular figure (parallelepiped) is equal to the product of its three parameters: length, width and height.
V = a b c h Image 1.
The board or beam is a parallelepiped. Length, width and height edged wood can be measured with a construction tape. Their dimensions are equal in cross-section (unlike unedged lumber, calculations of which will be given below). Therefore, we will calculate the volume of one wooden product.
Length: a = 6.1 m.
Width: b = 20 cm.
Thickness: c = 2.5 cm.
Let's convert the obtained values into common units of measurement (meters).
The length is the same: a = 6.1 m.
Width: b = 0.2 m.
Thickness: c = 0.025 m.
Let's do the calculations:
V = 6.1 x 0.2 x 0.025 = 0.0305 m3.
Image 1. Calculation of lumber per cubic meter using the formula: V = a b c h.
The resulting volume is a figure with several decimal places. There is a desire to round the value, convert 0.0305 to 0.031 m3. This is what most sellers do. On two, three, ten pieces this rounding is hardly noticeable. The tree becomes more expensive by pennies compared to the real, actual cost.
If calculations are carried out in large-scale construction (timber house, construction wooden frame under the roof), here the volume of the seller’s construction allowance, for the purpose of supposed simplification, is expressed in a more significant figure.
For example, you purchase one hundred of these floorboards (the actual volume of which is 0.0305 m3, but according to the seller it is taken as 0.031 m3).
The difference in material for one floorboard is:
0.031 – 0.0305 = 0.0005 m3.
For one hundred floorboards, this difference increases to 0.05 cubic meters, which you do not purchase, but pay to the seller. For a thousand boards this is already 0.5 cubic meters.
Now let's get back to determining how much lumber you have per cube. To find out how much board material a cubic meter of space contains, divide 1 cube by the volume of one floorboard (the resulting V value).
1: 0.0305 = 32.459 pieces.
The resulting number is also not an integer. This is where rounding can be to your advantage. The value 32.459 is rounded to 32.5 or 33 boards cubed.
Method 2: use ready-made tables
To avoid doing calculations, you can use ready-made tables.
Image 2. Table of the number of boards per cubic meter.
If you make a large volume of purchases of various lumber, the table will make it easier for you to determine the quantities of each type of wood purchased. To be sure that the payment corresponds to the amount of wood purchased, let’s check one of the table values with our own calculations.
Example. The selected floorboard (for which we measured the parameters earlier) exceeds the length required by standards by 10 cm (the standard length of lumber is 6 m). Therefore, technological length allowances of 10 or 20 cm are not taken into account in calculations. As a result, the tabular figure for the number of boards (size 25 x 200 mm) is 33 pieces. Image 2.
Method 3: for unedged lumber
Unedged boards come in different widths. At one end it can be equal to 30 cm, and at the other end it can be narrowed to 15 or 20 cm. How is the amount of building material per cubic meter calculated and how to calculate its cost?
In calculations of unedged materials, the average width of the wooden product is taken. They measure the widest place, the narrowest place and reduce their mathematical values to an average. For example:
The width of the larger edge is 32 cm. The other has a smaller width and is 18 cm (thickness is 25 mm, standard length is 6 m). We perform the following mathematical operations:
Average width b = (32 + 18) : 2 = 25 cm (250 mm to determine from tables or 0.025 m to do your own calculations).
You can then use the table above to edged material. Since it does not have the parameters 250 x 25 mm, we will use the value 250 x 50 mm (it will be exactly twice as large, since the thickness of 50 mm is twice our thickness). For a thickness of 50, the amount of material in a cube will be 13.3 pieces. This means that for our size the number of unedged boards (25 mm thick) will be
13.3: 2 = 6.15 pieces.
This is some interesting construction mathematics.
When implementing construction work for the construction of a residential building, a specialist must perform a large number of different tasks, one of which is: drawing up and calculating the estimated cost before the final finishing of the premises of a residential building. It is mandatory to calculate the required amount of various building materials, which is quite difficult to do. Therefore, such knowledge - how many boards are in a cube - is very important for a specialist who is engaged in the construction of a residential building and wants to complete the work as efficiently and quickly as possible.
Buying club: existing types of boards
To calculate exactly how many board pieces are in a cube, you will need to know not only what exactly a board cube means, but it is worth understanding important point that there are different types of boards and what is possible to purchase on modern market for performing various construction works. It should be noted that the cube of almost all materials, regardless of the type of material, is calculated in the same way, that is, according to one specific method. The types of boards have no influence on the calculation of the cubic capacity of this building material.
Non-grooved types of lumber are: timber, various edged boards, as well as unedged boards (they are an exception when calculating cubic capacity, because this process occurs a little differently). Tongue-and-groove types (which have special grooves for making joints) include: modern lining, blockhouse, flooring material, as well as imitation of natural timber. When you choose a tongue-and-groove type of building material for purchase, then you will need to pay attention to the fact that when making calculations, only the working width of the board without a tenon is used. If we talk about a blockhouse (imitation log), then when calculating the cubic capacity, only the thickness at its highest point is taken.
How many boards are in 1 cube: performing the calculation
Any person, even from his school days, understands how cubic capacity is calculated. For this procedure, it is necessary to calculate quantities such as: length, width and height. A similar principle is used to calculate the cubic capacity of 1 board. When performing such calculations, it is recommended to convert all available values into meters. The cubic capacity of 1 board, which has a cross-section of 150x20 mm. and a length of 6 m, is calculated as follows: 0.15 multiplied by 0.02 and 6, so that the cubic capacity of this board will be 0.018 cubic meters.
Let's apply the volume formula V= L*h*b (where L is length, h is height, b is width).
L= 6.0; h= 0.02; b= 0.15.
Thus, V= 6.0*0.02*0.15 = 0.018 m3.
To determine how many boards are in one cube: divide 1 m3 by cubic capacity (the volume of one board).
1 m 3 / V = N pcs.
1 m 3 / 0.018 m 3 = 55.55 pcs.
Thus, the number of boards in one cube is 55.5 pieces.
Finding out the cost of a certain type of board when the values of its volume is known is quite easy: 0.018 multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board costs, for example, 5,500 rubles, then the cost will be 99 rubles. At this point in the calculation, there is some trick of sellers and managers in construction stores, because the cubic capacity of the material is rounded to some integer values.
Such rounding can lead to such a moment that the price of 1 board (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that various boards for construction, which have a nominal length of 6 meters, the actual length is 6.1 - 6.2 m, which is not taken into account when selling this building material. This also applies to the purchase of a significant number of boards. This can be seen quite clearly if we use a 150x20 mm board as an example. The number of boards in a cube is a value of 55.5 pcs. But, in a cube they count 55 pieces, which when performing the calculation will have a value of 0.99 cubic meters. In fact, it follows from this that the overpayment for 1 cubic meter of this popular building material can amount to 1% of the real price. For example, 5500 instead of 4995 rubles.
To calculate the cubic capacity for a continuous type of board, slightly different methods are used. When we are talking about buying 1 board, then measuring its thickness, as well as the total length, is carried out in the same way as when choosing edged building material. In this case, the average width is taken for calculations - between a large value and a small one.
For example, when the width of the board at one end is 25 cm, and at the other 20, then the average value will be approximately 22 centimeters. When it is necessary to calculate the volume of a significant number of similar boards for construction, then you will need to lay them out so that the wide one does not differ from the narrow one, more than 10 cm. The main length of this material in the laid out stack should be approximately the same. After this, using a regular tape measure, an accurate measurement is made of the height of the entire existing stack of boards, and the width is measured (approximately in the very middle). The result obtained will then need to be multiplied by a special coefficient, amounting to a value from 0.07 to 0.09, directly dependent on the existing air gap.
How many boards are in 1 cube: special tables
To calculate the exact number of boards of a certain width and length in 1 cubic meter, various tables are used. Below are several such specialized tables, which indicate the cubic capacity of the common and in demand types of this material today. It is possible to calculate the volume of various boards of different sizes, for example, material for erecting a fence on your site, using the existing formula presented above.

How to calculate how much timber is in 1 cube?
We offer a simple calculation so that you do not get confused with the question of how to find out how much timber is in a cube. These calculation options are suitable if you know the dimensions of the timber. For example, let's take a beam 260 x 260 x 6,000 mm (6 meters). The same can be done for timber measuring 3 meters, 4 meters, 5 meters.
Formula for calculating the volume of timber:
100mm · 100mm · 6000 mm = 0.1m · 0.1m · 6m = 0.06 m3
Formula for calculating timber in pieces:
Beam length - 6 meters
1m3 / 0.06m3 = 16 pcs/m3
Difficult? Apparently not! But if the calculation is difficult for you, just use our table. The table contains calculations for all known dimensions of timber, which are given in GOST 8486-86.
The page contains answers to simple questions from people:
- How much timber
- How many cubes of timber
- How many cubes of timber?
- How much timber do you need?
- How much in one cube
- How many pieces in a cube
- How many bars are in a cube
- How to calculate how much timber is in 1 cube
Why know how much timber is in 1 cube?
There are two reasons for this:
- You can immediately calculate the total price of the volume of timber you need. To do this, you need to know the volume of 1 piece of timber, the price for 1 cubic meter and how many pieces in total you will need to implement your plans.
- You can calculate the total number of lumber units needed for the project. And this can be done by knowing how many cubes are required for the work, and by calculating the number of pieces of timber in 1 cube.
Meters are linear, square and cubic. Starting a big construction project or even small repairs, you should clearly understand these terms. The ability to correctly convert the amount of certain materials into linear or cubic meters will serve an excellent purpose in preliminary calculations of the cost of planned repairs or construction. For example, clearly understanding how much square meters in one roll of wallpaper, you can quickly calculate the amount required to cover a room or the entire apartment.
Calculations can be made in cubic meters, square or linear meters
If the upcoming repair or construction involves the use of wooden materials, you need to thoroughly study the calculations from linear meters in cubic, since prices can be presented on the market both per unit of material and per cubic meter. The amount of timber in a cube varies and depends on its cross-section. The easiest way to find out how many boards are in a cube is a table, but if it is not nearby you will have to remember the formulas.
What is a cubic meter
A cubic meter (abbreviated m³) is a unit of volume and is equal to the volume of a cube with an edge length of 1 meter. In accordance with GOST 8486-86 wooden materials must have measurable cross-sectional dimensions and lengths, so that you can easily calculate the number of boards included in a cube of material.
To determine the dimensions of the section, it is necessary to step back from the end of the beam at a distance of at least 10 cm and measure the width and height of the beam. By multiplying these values by each other, you get the cross-sectional area of the beam, multiplying it by the length to get the volume of one beam. By calculating the number of beams in one cubic meter, you can easily navigate between the cost of one beam and one cube of beams.
A cubic meter is equal to the volume of a cube with an edge side of 1 m
Calculation of lumber for construction before purchasing it
Of course, the easiest way is to come to the developer to explain what you want to see in the final version and agree to the proposed project. But, if you independently understand the calculations of the required amount of lumber, then even at the stage of discussing the cost of materials and work on building a house, you can get an idea of how realistic the prices are offered by the construction company.
Many developers calculate the required amount of material in cubes, some count individually, taking the standard length dimensions as 6 or 12 m. A clear understanding, for example, of how much timber is in a 150x150x6000 cube will protect you from overpayments.

The procedure for calculating the amount of timber in a cube
Despite the same principle of calculations, there are certain nuances in determining the cubic capacity and quantity of various lumber.
1. Basic formulas for calculating the number of bars in a cube
To determine how many boards are in a cube, with beams of a certain section, you need to know three measured parameters: length, width and height. First you need to calculate the volume of one beam using the formula V = a * b * l (here V – volume, m³; a – height, m; b – width, m; l – length, m)
Beam parameters: length, width, height
How many pieces of timber in a cube is determined by the formula:
Where, A is the amount of timber in a cube, pcs.;
1 – one cubic meter, m³;
V – volume of one beam, m³.
2. How to determine how many pieces are in a cube of 100x150 timber
In price lists construction companies for convenience, indicate the cross-section of the beam, that is, its width and height, for example, 100x150. Where 100 is the width indicated in millimeters, and 150 is the height. The length is most often 6 meters, or 6000 mm.
The volume of timber 100x150x6000 will be 0.09 m³.
V = 0.1 m * 0.15 m * 6 m = 0.09 m³. Here 0.1 is the width, m; 0.15 – height, m; 6 – beam length, m.
In this case, how much material will “fit” in one cubic meter can be found by dividing the cubic meter by the volume of one beam:
Where, 1 – one cubic meter, m³;
0.09 – calculated volume of one beam 100x150x6000, m³.
The characteristic cross-sectional shape of the timber is 100x150
This way you can easily calculate how many pieces of timber are in the purchased volume of material by multiplying the number of pieces by the number of cubes. For simplicity and speed of calculation, you can use the table: how many timber in a cube is 6 meters table.
3. How many edged boards are in 1 cube
The situation is similar in calculating the amount of edged boards in 1 cubic meter of wood. For example, the board used has the following parameters 100x25x6000 (width, height, length).
The volume of one board will be 0.015 m³.
V = 0.1 m * 0.025 m * 6 m = 0.015 m³
Quantity in 1 cube:
That is, a cubic meter contains at least 66 boards. When purchasing a cube of 100x25x6000 edged boards, you should get 67 pieces, rounding up. For example, when buying three cubes you should get at least 201 pieces, and when buying six - 401.
4. How many tongue and groove floor boards are there in 1 cube?
tongue and groove floor board for better installation It has a groove along its entire length on one side and a tenon on the other. When calculating the volume of one board, its length, height and net width are taken into account, that is, the width without taking into account the protruding tenon. For example, the size of the board reflected in the figure below is 28x90 mm.
tongue and groove floor board
If the board is 6 meters long, its volume will be:
V = 0.09 m * 0.028 m * 6 m = 0.01512 m³
Quantity in 1 cube:
5. How much wooden lining in 1 cube
The design of the lining vaguely resembles a tongue and groove floor board. It also has a tongue-and-groove connection and ventilation grooves, but the front side of the lining can have bevels, curves and even a convex surface, imitating timber.
For the calculation, the “pure” width is used, that is, the size without taking into account the spike; the height is taken as maximum value in the cross section of the board.
Types of lining with a clear example measuring the width and height of the board
The most common lining size is 100x14. With a board length of 6 meters, the number of linings in one cube will be at least 119 pieces:
Volume of one board:
V = 0.1 m * 0.014 m * 6 m = 0.0084 m³
Quantity in 1 cube:

What else to consider when counting lumber
One of the nuances in the production of lumber is their technological length, that is, the declared six-meter board in practice turns out to be 5-10 cm longer. This deviation is called technological and is not taken into account when calculating the linear meters of the board. The seller under no circumstances has the right to add them to the total length of the board.
When purchasing timber of a certain cross-section, it is important to measure the parameters upon acceptance or loading, since the slightest deviation of even 1 cm leads to huge losses, especially with large purchase volumes.
In addition to volume, it is important to remember the weight of the purchased material, which depends on the density of the material and humidity.
An example of calculating the weight of a beam based on the known density of wood (for materials of different moisture content, you must substitute the appropriate values instead of 860)
Tables for quickly calculating the volume of timber
Below are cheat sheets to quickly find out how much timber is in a cube - the table contains not only quantitative values of units of material per cubic meter, but also volumetric values of timber different sections. For example, the table will show how many boards are in a cube - 6 meters or 3 meters long will a board or timber be.

Features of lumber storage
To build a house made of wood, it is important to properly store the material so that its humidity is within 12%; if the humidity is higher, the shrinkage of the building will be slower.
Here are a few rules to remember when storing lumber:
The storage area must be level and dry.
To prevent moisture from entering the site onto the site, pallets are placed under the first layer of material, which can be replaced with scraps of boards or sleepers.
The distance between individual products should be maintained at least 2 cm for better air circulation.
After 1-2 rows, crossbars are placed across the length, which can be the same cuttings of boards.
If it is not possible to erect a canopy over the storage area to prevent precipitation from entering, the stacks are covered with film, excluding wrapping the ends, so as not to create a greenhouse effect inside.

Conclusion
Knowing the rules for calculating the required volume of building materials will help you save time and money, or simply make sure that the developer is conscientious. Therefore, if you do not have the skills to quickly convert one quantity into another, then when discussing the required amount of building materials you should keep with you at least a cheat sheet in the form of a cube table.
