One brick covers 0.02 square metres, which is 60 per square metre.

How to work out how many bricks you need

  1. Measure the area in metres and multiply length by width.
  2. Add 5 percent for cuts. Covers breakage and cuts at openings and corners. Bricklayers usually add 5 percent, more on a wall with many openings.
  3. Divide by what one brick covers, and round up. Suppliers do not sell part units.

What one brick covers

Why the figures differ between suppliers

Sixty bricks per square metre of wall in stretcher bond at half-brick thickness, and 120 per square metre at one-brick thickness. That is the figure for a standard 65mm brick with a 10mm bed, and it is the number to order against rather than the face size of the brick itself.

How much extra to order

5 percent. Covers breakage and cuts at openings and corners. Bricklayers usually add 5 percent, more on a wall with many openings.
