How Many Bricks Do I Need To Build A Wall?

Estimated reading time: 4 minutes

Learn how to get started with casual bricklaying for your home. Whether that’s building a wall for your back garden or building a wall at the front of the house. Big or small, in this article you will find out how to correctly size up and get started for your project.

Whether you have some experience or not, learn how to begin with the equipment you will need in order to start building a wall. We’ll look at how many tools and bricks you’ll need to get started.

We’re looking at:

  1. How many bricks you will need.
  2. Tools you will need.
  3. Types of walls.
  4. Wear and tear in your wall.

Beginners in brick laying and structure will need to avoid the following;

  • Insufficient amounts of bricks ordered – You wouldn’t want to stop and start halfway through the build to realise you need to order more. Especially when it can be cheaper to buy in bulk pallets, rather than ordering individual orders.

  • Avoiding ordering an overloaded amount of bricks – When the job is finished you wouldn’t want a pallet of bricks left unused.

If you’re a complete beginner, then what would be most recommended is to practice building your first few blocks together as more of a run through test. Order a few blocks of bricks and learn with less pressure before you start on your own home. This will prepare you for the feel for the structure, and will ultimately limit further mistakes moving forward with your main project.

Also important to note is having all the correct tools right in front of you for the wall. Last thing you need is getting half way through and being without tools that are required.

Getting started: How many bricks do I need?

Measure and plan out where the wall will take place in your garden. Once you know where the build will start and end, the general rule for most types of walls is to:

Multiply the wall height (in metres) X wall length (metres) X bricks per square metre.

Now we need to find out the correct numbers needed for bricks per square metre.

Each different type of wall build per square metre will be different from one another. See below the different figures and how you can multiply the bricks per square metre. This will grant you how many bricks you will need for the type of wall build you will choose.

Half brick walls – 

  • The area will be multiplied by 60 in this case. So, for half brick walls, 60 bricks for every per square metre is required.

  • Taking what we learnt above – Multiply the length of the wall, x the height and then multiply that area by 60.

  • This will tell you the number of bricks needed in total.


One brick wall – 

  • The area will be multiplied by 120 in this case. So, for a one brick wall, 120 bricks for every per square metre is required.

  • Taking what we learnt above – Multiply the length of the wall, x the height and then multiply that area by 120.

  • This will tell you the number of bricks needed in total.


Single brick piers in half brick walls – 

  • Single brick piers are built into a half brick wall, each pier requires an additional 14 bricks per vertical metre.

  • We calculate this by: Number of piers x wall height (metres) x 14 = number of bricks

 

One and a half brick piers in a half brick wall

  • One and a half brick piers are built into a half brick wall, each pier needs an additional 34 bricks per vertical metre.

  • We calculate this by: Number of piers x wall height (metres) x 34 = number of bricks

 

Calculating the number of blocks

  • A single block wall requires 10 blocks per square metre.

 

  • UK standard metric blocks are roughly 450 x 215 x 100mm.

 

  • Worthy to note – You can get some thicker metric blocks but this will not affect the required per square metre of wall. The mortar joints used are typically 10mm horizontally and vertically.

 

  • Multiply the Wall height (metres) x wall length (metres) x 10 = number of blocks

Please note – The figures mentioned above, do not include allowances for cuts and wastages. You may need to give yourself an extra order of bricks to support these numbers.

What tools do I need?

Most jobs whether they’re big or small, will require the essential tools to get started and finished. With project builds as such, there’s always further tools out there that will better enhance and help you out along the way.

So we’ll go through those tools that are completely essential for building a wall and those tools that are more extra support. Listed below are two categories from essential tools and extra tools.

Types of walls

What are the different types of brick walls that I can choose for building a wall?

  • Stretcher Bond – By far the most commonly used brick.
  • English Garden Wall
  • English Bond
  • English Cross Bond
  • Stack Bond
  • Monk Bond
  • Sussex Bond (or also known Flemish Garden Wall)
  • Header Bond
  • Flemish Bond

Spotting deterioration in your wall

Wear and tear in all types of walls, discovering deterioration in your wall will consist of:

  • Broken bricks with chips/cracks.
  • Loose bricks.
  • Stains.
  • Missing mortar.
  • Delamination.
  • Spalling when moisture is trapped inside of the brick.
