Formula and methodology
Formula: Net bricks = wall area/(brick face area); order bricks = ceil(net bricks × (1 + waste rate/100)).
The estimate treats the wall as a rectangle tiled by brick faces and makes the waste allowance visible.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Wall length — length units; minimum 1.0E-6; maximum 1000000
- Wall height — length units; minimum 1.0E-6; maximum 1000000
- Brick face length — length units; minimum 1.0E-6; maximum 1000
- Brick face height — length units; minimum 1.0E-6; maximum 1000
- Waste allowance — %; minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Wall length | 6 |
| Wall height | 2.5 |
| Brick face length | 0.2 |
| Brick face height | 0.06 |
| Waste allowance | 5 |
Net bricks = 1,250; order bricks = 1,313.
Assumptions and limits
- Brick face dimensions and wall dimensions use one length unit.
- No openings, mortar joints, bond pattern, cuts, or structural details are modeled.
- The order result rounds up to a whole brick.
