Brick Quantity Formula:
From: | To: |
Definition: This calculator estimates the number of bricks needed for a wall, accounting for mortar joints between bricks.
Purpose: It helps masons, contractors, and DIYers accurately plan brick quantities for construction projects.
The calculator uses the formula:
Where:
Explanation: The total wall area is divided by the area of one brick (including mortar joints) to determine the total number of bricks needed.
Details: Accurate brick counting ensures proper material ordering, minimizes waste, and helps with project budgeting and planning.
Tips: Enter the total wall area in square meters and the area of one brick including mortar (default 0.0168 m² for standard brick with 10mm mortar). All values must be > 0.
Q1: Why include mortar in the calculation?
A: Mortar joints significantly affect the total number of bricks needed, typically reducing the count compared to dry-stacking.
Q2: What's a standard brick size with mortar?
A: A standard brick (215mm × 102.5mm) with 10mm mortar joints covers about 0.0168 m² (225mm × 112.5mm).
Q3: How do I calculate for different brick patterns?
A: For patterns like Flemish bond, increase the calculated quantity by 5-10% to account for cuts and waste.
Q4: Should I add extra bricks for breakage?
A: Yes, it's recommended to add 5-10% to the calculated quantity for breakage and cutting waste.
Q5: How do I find the wall area?
A: Multiply wall length by height. For multiple walls, calculate each separately and sum the areas.
