The number is calculated to the nearest whole number, without taking into account any need to cut bricks. The unit menus can be used to choose appropriate units.

Fill in all the boxes to find how many bricks or blocks are in a wall (or how many you need to build a specific wall). The wall thickness should be quoted in number of brick thicknesses (i.e. 2 in the diagram above). Standard UK bricks are 8.5 x 2.5 inches, and standard US bricks are 8 x 2.25 inches.
