This article presents a size guide for bricks and details the dimensions for some of the most commonly-used bricks.
 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, and so the standard size for 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:
- With a standard mortar joint of 10 mm, a repeating unit of bricks laid in a stretcher bond will be 225 mm lengthwise and 75 mm in height.
- If bricks are laid cross-wise, two 102.5 mm depths plus two mortar joints gives the same repeating unit as the length of one brick plus one mortar joint, ie 225 mm.
- If they are laid height wise, three 65 mm heights plus three mortar joints gives the same repeating unit as the length of one brick plus one mortar joint, ie 225 mm.
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.

 Special bricks
Other than the standard rectangular brick, a number of special shapes exist for particular circumstances:
- Radial, tapered or arch bricks.
- Angle and cant bricks that form returns and chamfers.
- Bullnose bricks with rounded corners.
- Capping and coping bricks.
- Cill bricks.
- Plinth bricks.
- Slip bricks (thin bricks that can be used for cladding).
- Soldier bricks, that form returns for soldier courses.
Bricks can also be cut or hand made to size.
