By this point, you should be well on your way to being able to accurately calculate how many bricks you need for your next project.

You should now have all the information required for understanding UK brick dimensions and sizes. Be sure to read our types of bricks guide as well though, to ensure the correct material is always selected no matter the construction project you are working on.
