Detailed method for calculating the number of clay bricks (Manual)
To calculate it yourself for accuracy, follow these 4 steps:
Step 1: Find the net wall area.
formula: (Width x Height) - Door and Window Area = Net Area
- Example: A wall is 4 meters wide and 3 meters high (12 sq.m.) with one door (2 sq.m.).
- Net area: 12 - 2 = 10 square meters
Step 2: Select the brick type and multiply the quantity.
Let's assume we choose to use... Large two-hole clay bricks (Using 95 bricks per square meter.)
- calculate: 10 sq.m. x 95 blocks = 950 pieces
Step 3: Allow for damaged pieces (very important!)
It is recommended to allow for extra room. 10% Always be aware of the risk of cutting corners and breaking during transport.
- Allowance for: 950 x 1.10 = 1,045 pieces
- Total actual order: 1,050 pieces (Round up to the nearest whole number)
