Many people think about building a country house, but most postpone it until tomorrow due to ignorance of how to calculate the amount of timber per house. Why? Because the counting process itself is not free, and no one wants to pay for something that may not be implemented.
Let's try with you to understand how to correctly calculate the amount of this product for construction yourself.
Calculation of the product for the construction of a building
Factors that influence the numbers
The main thing to consider when calculating the amount of material per house is:
- what type of timber will be used in construction;
- how much we need;
- how many pieces are in 1 cubic meter;
- what is.
Calculation of lumber in cubic meters
Consider how to calculate the amount of timber in a cube in the simplest way, we can say that this is the basic principle of calculations. It should be noted that the above example is not accurate. To carry out more accurate figures, you need to have a project for the future home.
So, attention instructions:
- Calculate the perimeter of the building.
- Multiply the perimeter by the height.
- The result is multiplied by the thickness of the product.
- As a result, the result is the number of cubes of timber required for the construction of the building.
To calculate the product for interior walls, we use the same method. If desired, you can calculate not only the cubic capacity of the material, but also its quantity in pieces. Let's consider a separate example of how to calculate the amount of timber for a 3 m by 5 m bath with a height of 3 m.
Let's agree that the construction will use a size of 150 by 150 mm.
Instructions:
- (3 width + 5 length) × 2 = 30 m - the perimeter of the building.
- 30 perimeter × 3 height = 90 square meters - wall area.
- 90 area × 0.15 material thickness = 13.5 cubic meters - you need to build a box from a 3 × 5 timber with a height of 3 m.
Thus, the amount of timber for the walls is 13.5 cubic meters. But, it should be borne in mind that window and door openings will reduce the amount of material used.
In most cases, the masters do not take this moment into account, it is believed that it would be even better to throw about 20% on the stock, in the end we will get:
- 13.5 + 20% = 16.2 cubic meters will be required for this type of building.
Note!
When building a house from a bar, the first crown should be slightly thicker than the main product used for the construction of walls.
In our calculation, it is not taken into account, it must be calculated separately.
The first crown is laid from a thicker one, since in the future the mass of the whole house will fall on it, it is additionally recommended to treat it with machine oil or an antiseptic.
Calculation in pieces
Having calculated how many cubes of lumber for building a house, you can easily find out how much timber is required in pieces. You need this first of all when buying. Knowing the exact number of pieces, you will protect yourself from possible fraud on the part of the seller.
Consider a table of common sizes for this product with a length of 6m:
| 100x100 | 1 PC. - 0.06 cube | 16.67 pcs. cubed |
| 100x150 | 1 PC. - 0.09 cube | 11.11 pcs. cubed |
| 150x150 | 1 PC. - 0.135 cube | 7.41 pcs. cubed |
| 100x200 | 1 PC. - 0.12 cube | 8.33 pcs. cubed |
| 150x200 | 1 PC. - 0.18 cube | 5.56 pcs. cubed |
| 200x200 | 1 PC. - 0.24 cubes | 4.17 pcs. cubed |
In the above example, where we designated the cubic capacity of the timber for the bath, we will carry out further calculation of materials in pieces.
So, to find out the amount of material per house in pieces, we carry out the following calculation, for this the sum of 13.5 cubic meters, which is needed to build a bath, is divided by the cubic volume of the used timber, in our case it is equal to 0.135 cubic meters from the table :
- 13.5: 0.135 = 100 pcs
Knowing the correct amount of the product in pieces, you do not have to run around with a tape measure and calculate the volume when buying, in order to find out if you received the material according to the invoice correctly, you will only need to count the product by the piece.
Role of material height and thickness
Before calculating the quantity, you need to decide on the choice of the thickness and height of the product.
The material can have different thicknesses and heights, we list the main dimensions:
- 100x100 mm.
- 100x150 mm.
- 150x150 mm.
- 150x200 mm.
- 200x200 mm.
With the height, everything is simple, the higher the timber, the fewer the joints between the joints - construction work goes faster, and naturally, the number of pieces of material for building a house decreases. But the width is more important, especially when building for all-season living.
Note!
Not all lumber manufacturers are honest with the buyer, sometimes it happens that a 150x150 mm timber actually has a size of 140x140 mm.
What this will lead to is not difficult to guess, if 20 pieces of 150x150 mm beams are needed for a height of 3 meters, then with a size of 140x140 mm - 21 pieces and a half, and this is one and a half crown rows.
When planning year-round living in the house, it is recommended to use a bar 200 mm thick. It is necessary to insulate such walls, but for our climate there is enough such as foam or mineral wool 10 cm thick.
When building a bath, it is recommended to use a material thickness of 150 mm, it is quite enough for a short-term temperature maintenance. Well, if you decide to build a summer cottage for a summer vacation, then in this case the walls from a bar of 100x100 mm will be just right.
Advice!
When building a wooden house, in which it is not planned to live all year round, the thickness of the timber is not important.
After all, such a building is needed only for short-term use and mainly in the spring-autumn period.
Pay attention!
Despite the large thickness of the product, you still have to insulate the walls.
Indeed, in order for the house to fully fulfill its thermal insulation properties, the thickness of the walls should be about 50 cm.
Why do you need a home project
When calculating the material for building a house, the design of the house itself plays an important role. Indeed, only in the finished project you can see not only the exterior of the building, but also the internal arrangement of walls and elements that need additional calculation of the required material.
You can get a project of a wooden house in different ways:
- do it yourself;
- order from a specialist;
- buy a finished project;
- buy online;
- find on the internet.
It is possible to make a house project with your own hands, but it is difficult, since you should have special knowledge. And the point here is not only to draw a future house, it is also necessary to take into account the specifics of the climate, soil, air humidity and other points.
The most correct decision is to order a project from a specialist, the price for such services is not cheap, but this is the best option, the specialist will take into account all your wishes and possibilities of the area. This will protect you from many possible troubles, and will also have someone to ask you if problems arise.
Advice!
Do not buy projects on the Internet from unverified persons, most often they sell those projects that are posted on the Internet for public use.
Output
By making the correct calculations, you will ensure yourself an easy construction. There will be no need to think later - where to put extra products or, worse, to suspend construction because of their shortage.
If you still have any questions, watch the video in this article, you will not only learn how to calculate the timber on the calculator, but you will also be able to calculate the approximate cost of the future home. You will definitely not have any doubts about your ability to calculate the material with your own hands.
Lumber is one of the most demanded materials for construction at the moment. The scope of application is simply huge. Directly in the construction site, lumber is used at almost every stage; it is included in the full cycle of general construction work, from foundation formwork to supporting structures on the roof. This type of material is very unpretentious to use, which makes working with it irreplaceable and enjoyable.
Features of the calculation of lumber:
This lumber calculator helps you quickly calculate from pcs to m3 and vice versa. For the calculation, you must indicate the length of the board or timber in millimeters (S1). Width and thickness (S2 / S3), also, if necessary, you can immediately find out the cost of the calculated sawn timber by filling in the appropriate field. You can check the cost of the forest with any supplier in your area, or at the nearest construction market. Usually, the price is indicated per cubic meter, and this script will play an irreplaceable role here for the calculation. After all, agree to calculate the cost of several boards, when you are told the cost per cube, it is quite problematic.
Having mastered this cubic meter of lumber, you will no longer be faced with the question of how to calculate the lumber. Entrust the routine calculation to the lumber calculator, and you will not only save your personal time, but also eliminate errors in calculations, which will definitely lead you to save money.
What types of lumber are
- Edged board is perhaps one of the most demanded materials on the building materials market. This type of material is used everywhere, in the construction of houses, baths, utility rooms, individual structural elements such as stairs, fences, windows, doors, roofs, and so on. Our specially developed program will help you calculate the cubic capacity of boards in a cube. Save this page in bookmarks, and you can always, quickly and conveniently, be able to calculate any wood.
- A bar is a product of rectangular or square sawn timber, as well as a board is widely used not only in the construction market, but also in furniture production. Buying this material it is easy to fall for the tricks of unscrupulous sellers. In addition to its moisture content, clear dimensions, class and quality, cunning managers can easily cheat you on the total volume. Do you know how to correctly calculate the cubic capacity of a bar? Just use this online calculator of lumber cubic capacity, and save your nerves and money.

An online calculator for calculating the amount of timber per house can now be found on the website of any major seller of building materials. But if for some reason a calculator is not available - how to calculate the amount of timber per house manually? Obviously, we will have to recall the half-forgotten school geometry course.
If several standard sizes of lumber are used during the construction, the calculation of the amount of timber per house is performed separately for each of them. For example, with a bar of 200 * 200 and internal partitions made of a material with a cross section of 100 * 100, we separately calculate the volume for the capital enclosing structures and for the partition.
Negligible values
As you can see, without using an online calculator, it is not difficult to calculate how much timber you need per house.
However, it should be understood that with the given calculation scheme, we deliberately neglect some of the subtleties of construction:
- The actual volume of each wall will be slightly less than the calculated one due to the fact that rectangular parallelepipeds, which are walls, partially intersect in space;
- In addition, we completely neglect window and door openings (with the exception of floor-to-ceiling panoramic windows).
The reason we ignore these points is very simple: none of these factors affect the volume of purchases.
As a rule, when designing and building a log house with your own hands, the dimensions of the structure are deliberately made multiples of the length of the lumber that is supposed to be used.
Additional lengths are rarely used in construction, because they:
- Reduce the mechanical strength of the log house, its ability to withstand deforming loads;
- Deteriorate the thermal insulation of the building due to blown seams;
It is worth clarifying: insulation is highly dependent on the method of cutting adjacent segments.
The horizontal connection in a half-tree is really blown by all the winds, but it is worth turning it vertically - and in terms of thermal insulation, the connection will be no different from a solid crown.
- Requires unwarranted investment of time to make unnecessary connections.
reference Information
Lumber in large volumes is bought and sold in cubic meters. The price is indicated by the seller exactly per unit of volume.
However, in some cases, the buyer needs to purchase a small amount of timber, measured in units. The most typical example is the purchase of materials for beams or floor logs: it is much easier to count the number of beams at a known step than their total volume.
In this case, the following table may be useful to him, which is relevant for a measured length of 6 meters.
Calculation examples
Problem 1
The instructions for performing calculations are already familiar to us; it only remains to follow the above algorithm.
- The perimeter of the house is 6 * 4 = 24 meters. The area of the outer wall is 24 * 2.7 = 64.8 m2;
- The horizontal section of the timber in SI units corresponds to 0.15 m;
- The volume of the walls, therefore, is 64.8 * 0.15 = 9.72 m3.
Task 2
Let's complicate the task, still without using the calculator: how to calculate the number of cubes of timber for a house measuring 12 * 12 * 3.5 meters, if the outer walls are erected from sawn timber with a section of 250 * 250, and the inner cruciform partition dividing the structure into four equal the area of the room - from a bar with a section of 100 * 100 mm?
It is easy to guess that in this case the area of the outer walls and the partition will be the same. Let's calculate this area: 12 * 4 * 3.5 = 168 m2.
Now we translate the thickness of the walls into SI values:
- 250 mm = 0.25 m;
- 100 mm = 0.1 m.
So, we need 168 * 0.25 = 42 cubic meters of material with a larger section for the outer walls and 168 * 0.1 = 16.8 m3 of 100 * 100 timber for the partition.
Advice: in practice, it is better not to increase them to improve their heat-insulating qualities, but to insulate the house from the outside with mineral wool slabs.
Thus, the owner will receive better insulation at a much lower cost.
Problem 3
- The height of its two floors is 6.5 meters;
- Dimensions - 6 * 12 meters;
- External wall thickness - 200 mm (timber 200 * 200);
- The thickness of the partitions is 100 mm, the height is 3.1 meters, and their total length on both floors is 92 meters;
- The house has three floors on beams measuring 150 * 100 mm, laid with a step of 1 meter.
Let's break down a relatively complex problem into several stages.
- We calculate the volume of lumber for the outer walls of the log house. It is equal to (6 + 6 + 12 + 12) * 6.5 * 0.2 = 46.8 m3;
- We calculate the volume of material for the internal partition. 92 * 3.1 * 0.1 = 28.52 m3;
- We count the number of beams. With transverse laying, 13 pieces will go into each floor (the first and last beams are located directly near the walls parallel to them); for all three floors, you will need 13 * 3 = 39 pieces;
All project cards on our website have a detailed description and approximate cost of the finished house. But you can calculate a bar for a house or a bath using a calculator by changing the thickness of the walls or making other edits. To use the calculator, select the following options:
- type of building (house or bath);
- complete set (turnkey or for shrinkage);
- log house project (choose from our catalog);
- section of the bar (90x140 mm, 140x140 mm or 190x140 mm);
- foundation structure (pile-screw, tape, etc.);
- ceiling height (number of wall crowns);
- type of interior decoration (lining, block house, etc.);
- type of exterior decoration (lining, block house, etc.);
- insulation of floors and roofs (knauf, rockwool of various thicknesses).
You also need to fill in the fields: type of windows, roof material and other data. Our calculator for calculating timber will help you in solving the main construction issue - how much will the finished log house cost?
Of course, during construction, it is very important to correctly calculate the required amount of materials. After all, each log costs a lot of money, and its transportation is fraught with certain difficulties. And if a mistake was made in the calculations, this can lead to serious difficulties. Our online beam calculator will help you do this online.
With a lack of material, you have to interrupt the construction process, and wait until the timber is delivered in the right amount. If too much timber was bought, then there will be a few extra logs, the money for which was thrown to the wind.
But if, when calculating, you use a calculator to calculate the amount of timber, then you will get the most accurate result. It is important that the calculator is very easy to use, thanks to which even an inexperienced person will be able to carry out the necessary calculations in the shortest possible time.
First, you need to enter the approximate dimensions of the future house - the height, length and width of the walls. Of course, in order to know this data, you need to have
Only then will you be able to use accurate data.
The next step is to choose the length of the timber. The timber can be of different lengths, usually from 5 to 12 meters. This allows you to choose the optimal length for any project without overpaying unnecessary funds and without wasting time connecting two elements.
The last step is to indicate the section of the bar.
In private construction, a bar with a section from 150x150 to 200x200 is usually used. The choice of a suitable bar depends on the desires and capabilities of the future owner of the house. 
But it is worth noting that the thicker the timber, the better heat and sound insulation characteristics it will have. However, at the same time, the cost of the building material also increases. So, it is worth taking seriously the choice of material so that it meets not only your requirements, but also its cost does not make the material inaccessible to you.
