About this calculator
Count bricks for a wall from its size, with mortar quantities. Covers Australian standard (230 × 110 × 76), double-height and modular bricks in single or double thickness.
How it’s calculated
Each brick, together with its share of mortar joint, covers one module of wall face. A standard 230 × 76 mm brick face with 10 mm joints covers 240 × 86 mm, giving about 48.4 bricks per m², usually quoted as 48–50. A double-thickness wall doubles the count.
Worked example
With these inputs:
- Wall length
- 8 m
- Wall height
- 1.2 m
- Openings area
- 0 m²
- Brick size
- Standard 230 × 110 × 76 mm
- Wall thickness
- Single skin (e.g. brick veneer)
- Mortar mix
- 1:1:6 cement:lime:sand (M3, general)
- Waste allowance
- 5%
the result is:
- Bricks needed
- 489 bricks
- Wall area (net)
- 9.6 m²
- Mortar volume (wet)
- 0.27 m³
- Mix 1:1:6 needs
- 4 × 20 kg cement + 2 × 20 kg lime + 0.3 m³ brickies sand
- Pallets (about 450 each)
- 2 pallets
Tips from the trade
- 5% waste is normal for new brick. Use 10% for reclaimed brick or a lot of cutting.
- Buy every brick for one wall at the same time. Different batches can vary in colour.
- For 1,000 bricks in a 1:1:6 mix, allow roughly 0.6 m³ of brickies sand, 7 bags of cement and 3 bags of lime.
Common questions
How many bricks in a square metre?
About 48 standard bricks per m² for a single skin such as brick veneer, and about 96 for double brick.
