How it works
Per m² = 10000 ÷ (length × height)
Divide a square metre by the brick face area to get bricks per m², then multiply by the wall and add about 10% for cuts and breakage.

Frequently asked questions
Why add 10%?
To cover cuts, breakage and waste — running short mid-job is costly.
Does mortar change the count?
Slightly — including the mortar joint in the brick size gives a more accurate count.
