Brick Dimensions & Bonds (Australia)

230 × 110 × 76 mm — the standard Australian clay brick, and the 86 mm course that sets out the whole job. Plus the bonds you will be asked for.
Standard brick (work size)
| Length × Width × Height | 230 × 110 × 76 mm |
| Standard mortar joint | 10 mm |
| One course (brick + joint) | 86 mm |
