About this calculator
Estimate the bricks for a wall from its size, the brick size and the mortar joint. Doors and windows are taken off, and a little extra is added for breakage.
How it works
- Each brick takes up its face plus the mortar joint, so one brick covers (length plus joint) times (height plus joint).
- Bricks are the wall area divided by that area, times (1 plus waste divided by 100), rounded up.
- This counts a single layer of bricks laid flat.
This is a preliminary estimate for planning and shopping lists. It is not a structural design, a safety check or a building-code approval. Ask a qualified professional before you build.
Common questions
Which brick size should I enter?
The size printed on the brick you plan to buy. Sizes vary by country and make.
What about a thicker wall?
Multiply the count by the number of layers, or ask your builder or supplier.
