FAQ

Frequently asked questions

How do I calculate wall volume?

Multiply the wall's length × height × thickness.

Why include mortar in the brick volume?

Mortar joints between bricks take up space too, so including them gives a more accurate total count.

Should I order extra bricks?

Yes, many builders add 5-10% extra for breakage and cutting — this gives the exact theoretical count.

Does brick size affect the calculation?

Yes — larger bricks (with mortar) mean fewer bricks are needed for the same wall volume.
