If you’re doing a little home DIY, knowing the answer to this question can save you a lot of headaches.

How to calculate how many bricks you need

Unfortunately, there’s no easy answer to this question, but we can certainly take you through the steps to get a decent estimate to work with.

One of the hardest parts of starting a new project that uses brick is trying to order the correct (or nearest) number of bricks so you don’t end up with too many taking up space in your garden or at the front of your home. Over-ordering is such a waste of money, too, so let’s avoid that!

Half-brick thick wall

First up, let’s assume that you’re building a brick wall of some kind. Measure the length that you want and times that by the height that you want. That number is the area. Multiply the area by 60, and that should give you the most accurate number of bricks you’ll need for a project.

Better be safe than sorry, though! Add 10% to that final number for any wastage incidences. That includes broken bricks, mistakes, or things just going a bit pear-shaped.

This figure only works for brick walls that are single layer, and, therefore, are 60 bricks per square metre. For everything else, well, it’s a bit more complicated.

One-brick thick walls

Similar to the last measurement, but we’re adding more bricks. To create a wall that is a thick as a single brick, you’re looking at 120 bricks per square metre. These walls don’t need support (unlike half-brick thick walls) and can be freestanding.

Your wall will end up being 215mm wide, which is the standard size of most bricks. There will end up being two layers to this wall, alternating between a course of brick that is laid with the long edge of a brick exposed, and a course of brick that has the short edge exposed.

These are called stretcher course and header course.

Making a pillar of brick is quite different to creating a wall. A pillar that uses a single brick is 14 bricks per metre (vertical, rather than horizontal), or 34 bricks per metre for a pillar that is a brick and a half.


Always add an extra 10% of bricks on top of your calculation for wastage. You never know what’s going to happen while you’re building, and that extra 10% will stop any project delays.

When your project is finished, why not use the extra bricks to make something small for your garden? A fire pit is simple enough and requires very few bricks.
