Question 1

What are standard brick dimensions in the UK?

Accepted Answer

The standard brick size in the UK is 215 x 102.5 x 65 mm (8.46 x 4.04 x 2.56 inches in imperial). This is normally paired with a standard width of 10mm mortar joints.

Question 2

What are the standard dimensions for a concrete block in the UK?

Accepted Answer

Unlike bricks, which tend to follow a standard size (see above) concrete blocks come in a range of different dimensions. The most common size for a concrete block is 440 x 215 x 100mm. This is designed to complement brick dimensions, so is the same length as 2 bricks, and the same height of 3 bricks (including the 10mm mortar joints between them).

Question 3

How many bricks do I need per m2?

Accepted Answer

If you’re using standard bricks, a rough guide is that you’ll need around 60 bricks per m2 for a single layer wall. If you’re working on a two-layer wall, you’ll need to double this: about 120 bricks per m2.
