How Brick Quantity Calculator Works?
Calculate the number of bricks and mortar volume needed for your wall construction based on wall dimensions and thickness.
Enter the wall length, height, and choose the wall thickness (half brick or full brick).
The calculator computes the total wall area (Length x Height) in square meters.
Based on standard modular brick size (190mm x 90mm x 90mm) with 10mm mortar joints, the number of bricks per square meter is determined.
Mortar volume is calculated as the specified percentage of the total wall volume.
The total number of bricks is computed by multiplying wall area by bricks per square meter.
Formula Used
Wall Area = Length x Height; Wall Volume = Wall Area x Thickness; Bricks Needed = Wall Volume / Volume of One Brick (with mortar); Mortar Volume = Mortar Ratio% x Wall Volume
Always order 5-10% extra bricks to account for breakage during transport and cutting. Half brick walls use approximately 57 bricks per sq m, and full brick walls use approximately 115 bricks per sq m.
Important — Read Before You Decide
- Standard brick size in India is 190mm x 90mm x 90mm (modular brick).
- Mortar joints are typically 10mm thick on all sides of the brick.
- Half brick walls (4.5 inch) are used for non-load-bearing partitions, while full brick walls (9 inch) are used for load-bearing structures.
- Always order 5-10% extra bricks to account for breakage during transport and cutting.
- The quality of bricks directly impacts the structural integrity and longevity of the wall.
- Proper curing of mortar joints for at least 7 days is essential for maximum wall strength.
What Happens If You Ignore These?
- Underestimating brick quantity can cause project delays while waiting for additional material delivery.
- Using too little mortar weakens the bond between bricks and compromises structural safety.
- Incorrect wall thickness selection can lead to structural failure in load-bearing walls.
- Overordering bricks wastes money and creates storage problems at the construction site.
Smart Tips
- For half brick walls, expect roughly 57-58 bricks per square meter of wall area.
- Always check bricks for uniform size and color before purchasing in bulk.
- Soak bricks in water for at least 2 hours before laying to ensure proper mortar adhesion.
- Use a plumb bob and spirit level frequently to keep walls straight and vertical.
