How many bricks are needed per square meter? (Calculation program + latest price 2026)
Calculating... How many bricks are needed for 1 square meter? Or perhaps you have the wall space but aren't sure how many red bricks you need?
The number of bricks used per square meter. There is no single best price for every type of brick. The number of bricks needed depends on the size of the brick, the joint pattern, and the mortar grooves. For example, approximately 40–45 large 3-hole bricks are used per square meter, while approximately 120–130 small 2-hole bricks may be needed per square meter, and only about 25–28 Jumbo 8-hole bricks per square meter are required.
AY Contento therefore developed... Online brick calculation program To help calculate everything from net wall area, number of bricks, allowance for breakage, mortar, plaster, brick weight, to estimating the number of truckloads, it makes it easier for homeowners, contractors, and purchasing departments to estimate materials before ordering.

How many bricks are needed for one square meter?
The answer depends on the type and size of brick chosen. The usage rates found for AY Contento's current products are as follows:
| Types of Mon bricks | Approximate size | Number of users |
|---|---|---|
| Jumbo 8-hole clay bricks | 7 × 11 × 25 cm. | 25–28 pieces/sq.m. |
| Large 3-hole brick | 6 × 10 × 20 cm. | 40–45 blocks/sq.m. |
| 4-hole brick | 5 × 6 × 15 cm. | 90–95 blocks/sq.m. |
| Large 2-hole brick | Approximately 5 × 6 × 15 cm. | Approximately 95–100 blocks per square meter. |
| Small 2-hole brick | 3 × 6 × 14 cm. | 120–130 blocks/sq.m. |
| Solid red brick | 3 × 6 × 14 cm. | 130–140 blocks/sq.m. |
| Red Brick, TIS 77-2565 | 4 × 6.5 × 14 cm. | 85–90 or 120–130 blocks/sq.m. along the construction line. |
Current AY product information confirms examples such as 3 large holes (40–45 pieces/sq.m), 4 holes (90–95), 8 holes (25–28), 2 small holes (120–130), and solid bricks (130–140 pieces/sq.m).
Therefore, before asking "How many red bricks are needed per square meter?", you need to know what type of brick it is. Because the quantity can differ by more than four times between small bricks and jumbo bricks.
Why are different types of clay bricks used in different quantities?
The main factor is: Brick surface area and mortar groove thickness.
Larger bricks cover a larger wall area per brick, therefore fewer are needed. For example, approximately 25–28 8-hole clay bricks measuring 7 × 11 × 25 cm are needed per square meter, while approximately 120–130 small 2-hole clay bricks measuring 3 × 6 × 14 cm are needed per square meter.
The thickness of the grout joint can also change the actual number. Market calculations often take grout joint dimensions into account, such as 1–1.5 cm. Therefore, the number displayed in the calculator should be used as the actual number. Estimates for purchasing planning. And you should double-check with the actual product batch before ordering large quantities.

Formula for calculating the number of bricks needed.
The principle of Calculating the cost of clay bricks. is:
Number of bricks before allowance = Net wall area × Number of bricks per 1 sq.m.
by:
Net wall area = Total wall area − Area of doors and windows
Then add a margin for cutting, breaking, or damage:
Recommended quantity = Quantity based on area × (1 + % for material allowance)
For example, if there is a net area... 100 sq.m. And select 3-hole clay bricks using the specified ratio. 45 blocks/sq.m.
100 × 45 = 4,500 pieces
If 5%:
4,500 × 1.05 = 4,725 pieces
In case 10%:
4,500 × 1.10 = 4,950 pieces
Example: How many 3-hole bricks are needed for 1 square meter?
3-hole brick The large mass of AY Contento is approximately... 6 × 10 × 20 cm. Weight approximately 1.6 kg/block And use approximate. 40–45 blocks per square meter.
The calculator is set to a default value of... 45 blocks/sq.m. This represents the upper end of the range, helping to mitigate the risk of insufficient brick orders, but users can adjust the rate to match the actual batch or construction method.
How many two-hole bricks are needed per square meter?
We need to differentiate first what it is. Small lump or large lump
Small, two-hole clay bricks Dimensions approximately 3 × 6 × 14 cm. Approximately... 120–130 blocks/sq.m. According to current AY data, the grout joint is approximately 1.5 cm.
part Large two-hole clay bricks A lower amount will be used, approximately... 95–100 pieces/sq.m. Based on size and laying pattern, this is similar to current market data that answers the query "How many bricks are needed per square meter?"
How many 8-hole bricks are needed per square meter?
8-hole brick Jumbo is a large brick, approximately the size of... 7 × 11 × 25 cm. Use only 25–28 pieces/sq.m. And since they weigh approximately 2.5 kg per piece, fewer pieces are needed compared to smaller bricks. However, weight and transportation must also be considered.
How is the weight of clay bricks conforming to Thai Industrial Standard (TIS) 77-2565 calculated?
Red Brick, TIS 77-2565 AY Contento's size is approximately... 4 × 6.5 × 14 cm. Weight approximately 0.53 kg/block
The amount used depends on the construction method:
Wall thickness approximately 4 cm → 120–130 pieces/sq.m.
Wall thickness approximately 6.5 cm → 85–90 blocks/sq.m.
Therefore, Calculator V2 has options. Construction line Increase the quantity when choosing this type of brick; do not use the same number of bricks for all wall sections.
What percentage of extra bricks should be allowed?
During construction, cracking, cutting corners, and damage may occur during transport, so it's advisable to order extra materials beyond the amount needed for the area.
The calculator offers the following options:
0% — I want to see the theoretical number.
5% — Suitable for general tasks where on-site control is good.
10% — For conservative estimations or tasks with significant truncation.
Many AY product pages recommend accommodating approximately 5–7% for actual applications, such as 2-hole and 8-hole bricks.
How does the program calculate vehicle weight and trips?
Different types of clay bricks have different weights per brick, so the number of truckloads should not be estimated using a single, fixed number of bricks.
Calculator V2 calculates first:
Total brick weight = Recommended number of bricks × Weight per brick
Then:
Number of truck trips ≈ Total brick weight ÷ Specified payload per trip
Users can adjust the load weight per trip to match the actual vehicle, such as a 6-wheel truck, a 10-wheel truck, or according to route and site conditions.
The number of train trips is therefore... Estimates to aid in planning. This is not a confirmation of legal load capacity or actual vehicle specifications.
How are mortar and plaster calculated?
The calculator estimates the amount of mortar needed based on the area, type of brick, number of wall layers, and percentage allowance for materials.
The amount of plaster is calculated from:
Net area × Number of sides plastered × Plaster thickness
For example, a 100 sq.m. wall, plastered on both sides, equals a total plastering area of 200 sq.m. If the plaster thickness is increased, the amount of plaster required will also increase.
Because the coverage rate of each cement product varies, the results should be used as an estimate. It is advisable to check the coverage information on the actual cement product you intend to use before ordering.
❓ Frequently Asked Questions (FAQ)
The yield depends on the type and size of the brick. For example, 8-hole bricks yield approximately 25–28 bricks/sq.m, 3-large hole bricks approximately 40–45 bricks, 4-hole bricks approximately 90–95 bricks, and 2-small hole bricks approximately 120–130 bricks/sq.m.
The terms "red brick" or "Mon brick" encompass various sizes, so there isn't a single quantity. You should select the brick type first, then determine the number of bricks per square meter for that particular model.
about 40–45 blocks/sq.m. For the 6 × 10 × 20 cm model of AY Contento.
about 120–130 blocks/sq.m. The approximate dimensions are 3 × 6 × 14 cm.
about 25–28 pieces/sq.m. For dimensions of 7 × 11 × 25 cm.
about 130–140 blocks/sq.m. It depends on the mortar groove and the batch of goods.
For general work, a thickness of around 5% is sufficient. For jobs involving many angles, cuts, or where greater risk tolerance is desired, 10% can be chosen.
The area of the opening should be subtracted from the total wall area before calculating the number of bricks. Calculator V2 can add multiple doors and windows and will automatically subtract them.
Yes, approximately. Total weight of bricks ÷ User-specified load per trip However, you should reconfirm the actual vehicle and shipping restrictions with the sales department.
