Estimate how many bricks a wall needs from its area and the bricks per square metre — about 50 per m² for a standard single skin — plus a waste allowance.
This is bricks only — allow separately for mortar (roughly 0.5–0.7 bags of cement plus sand per m² of single-skin wall), and deduct large openings from the wall area.
traqR keeps brick and material quantities on the job card so what you estimate flows into the quote and order.

A single skin of standard Australian bricks with 10 mm joints is about 50 bricks per m². A double-skin (cavity) wall needs roughly double.
Cuts and breakages mean allowing a few percent extra — around 5% is typical for standard brickwork.
For standard Australian bricks (230 × 110 × 76 mm) laid with 10 mm mortar joints, a single skin is about 50 bricks per square metre. A double-skin or cavity wall has two leaves, so it needs roughly 100 per m². Different brick sizes change the figure.
Multiply the wall area (length × height, less openings) by the bricks per m², then add waste. An 8 m × 2.4 m single-skin wall is about 19.2 m², so roughly 1,010 bricks with 5% waste.
No — it counts bricks only. As a rough guide, a single-skin wall uses in the order of 0.5–0.7 bags of cement plus sand per square metre for the mortar, but this varies with joint size and mix. Estimate mortar separately.
For large openings, yes — subtract their area from the wall area so you don’t massively over-order. For small openings the extra bricks are useful waste allowance, but big windows and doors make a real difference.
This calculator estimates brick quantity for a wall and is a general guide. It doesn’t include mortar, reinforcement or structural design, and brick counts vary with brick size and jointing. Deduct large openings and confirm quantities before ordering. Structural masonry must follow the relevant standards.
