The Ultimate Guide to Calculating Bricks with Alpando Toolbox
Embarking on a construction project, whether it's a simple garden wall, a house extension, or a full-scale building, requires meticulous planning. One of the most fundamental steps is accurately calculating the number of bricks required. A miscalculation can be costly and frustrating; ordering too few bricks leads to work stoppages and potential color mismatches between batches, while ordering too many results in wasted money. Alpando Toolbox brings you a powerful, free bricks calculator that accounts for wall dimensions, brick size, mortar joints, wall type, wastage, and cost.

Key Factors in Brick Calculation
1. Wall Surface Area
Wall Surface Area = Length × Height — the starting point for any brickwork calculation.
2. Mortar Joint Effect
The mortar joint between bricks significantly affects the number needed. Effective Brick Area = (Brick Length + Mortar) × (Brick Height + Mortar)
3. Single Leaf vs Double Leaf
- Single Leaf: Half-brick wall (one brick thick) — used for garden walls, partitions.
- Double Leaf: Full-brick wall (two bricks thick) — standard for exterior walls, requires ~2x bricks.
4. Wastage Factor
- Simple straight walls: 5-7% wastage
- Walls with corners/opening: 10-15% wastage
5. Mortar Volume
Mortar Volume = Total Wall Volume - (Number of Bricks × Volume of One Brick)
