This article presents a size guide for some of the most commonly-used bricks.

[edit] What size are standard bricks?

The standard co-ordinating size for brickwork is 225 mm x 112.5 mm x 75 mm (length x depth x height). This includes 10 mm mortar joints, so the standard size of a brick itself is 215 mm x 102.5 mm x 65 mm (length x depth x height).

This gives a ratio of 3:2:1, meaning that:

This makes it straight-forward to create complex patterns of bricks within the standard co-ordinating size. See Types of brick bonding for more information.

60 standard bricks laid in a stretcher bond (lengthwise) are required for every square meter of wall.
