How to use the brick calculator
This calculator helps you estimate how many bricks (pcs) and how much mortar (m³) are needed to build a wall. It’s useful for workers, foremen, and DIY builders.
Step by step
1) Choose a mode — Wall (L×H) or Area (m²).
2) Enter openings area (windows/doors) if needed — it will be subtracted.
3) Select wall thickness — ½, 1, 1½ or 2 bricks (or enter manually).
4) Choose brick size — a preset or custom dimensions (mm).
5) Set joint thickness — usually 10 mm.
6) Click “Calculate” — you’ll get bricks, mortar, a table, and a chart.
What the abbreviations mean
- m² — area in square meters.
- m³ — volume in cubic meters.
- mm — millimeters (brick and joint sizes).
- pcs — number of bricks.
- L×H — wall length × wall height.
- Joint — mortar layer thickness between bricks.
How the calculator works
First, it calculates the net masonry area (wall area minus openings), then the wall volume = area × thickness. Next, it estimates brick count using a “module” (brick + joint) and mortar volume:
mortar ≈ wall volume − solid brick volume
This is an estimate for planning. For real projects, add 5–10% extra.
Frequently asked questions
How accurate is this calculation?
It’s a practical estimate. Real usage depends on workmanship, cutting waste, wall irregularities, and joint thickness.
Why should I add extra bricks?
Some bricks break or are cut. Builders usually add +5–10%.
Does it account for windows and doors?
Yes. Enter the total openings area (m²) — it will be subtracted automatically.
Why is mortar volume so large?
Mortar fills all joints between bricks. Thicker joints mean more mortar.
Can I use custom brick sizes?
Yes. Select “Enter manually” and input your brick dimensions in mm.
