Use this calculator to estimate the number of bricks or blocks needed for a wall, including a wastage allowance. It is useful for garden walls, extensions, garages and any project where you need to order the right quantity of masonry units without over-ordering.
5 m garden wall
A 5 m × 1.8 m single-skin wall needs roughly 540 bricks before wastage.
Extension shell
A 6 m × 2.5 m one-brick extension leaf needs around 900 bricks.
Garage blockwork
A 5 m × 2.4 m block wall needs about 120 blocks for a single skin.
The calculator gives you a sensible starting quantity. For structural work, always confirm the specification and grade with your engineer or building control before ordering. We stock the standard trade lines and can source specialist grades or sizes with short lead times.
