Brick Calculator
Use our Brick Calculator to determine how many bricks you require, to ensure you don’t run short or incur any wasted materials.
How many Bricks do you need?
If you are going to start construction work and you want to optimise your costs, a brick calculator could be your new best friend, helping you estimate how many bricks you need to cover a particular wall surface.
If you are wondering how many bricks you need, it’s always better to calculate it than to guess it. Otherwise, in all probability, you’ll either run out of them, or you’ll have too many left.
Whether you’re building a wall, a new extension or a brick barbeque, our brick calculator we’ll help you cut down on waste and over-spending on building materials you don’t need.
Using our brick calculator is very easy. All you have to do is key in the values needed, and our brick wall calculator will display the results right away.
Keep on reading to see how you can accurately estimate how many bricks you will need for your project.

You can work out how many bricks you need using this simple equation:
bricks needed = (L * H) / ((l + t) * (h + t)),
where:
L– Length of the wall;H– Height of the wall;l– Length of a brick;t– Thickness of mortar joint; andh– Height of a brick.

A brick wall needs approximately 5 bricks per square foot with the standard 7.5″ x 3.5″ bricks.
We also need the same number of bricks per square foot with the standard size of 9.5″ x 2.75″ bricks.
The larger the bricks are, the fewer bricks we need to cover a square foot.

- Decide on the mortar thickness you want to use and add it to the length of your brick.
- Add the mortar thickness to the height of your brick.
- Multiply these sums together to get the area of a brick with mortar on one side and its bottom.
- Divide your wall area by the product you got from step 3 to find your needed brick quantity.

There are three main types of bricks – facing bricks, engineering bricks and common bricks. However, there are many more variations, styles and manufacturing processes that make different bricks suitable for different jobs.
Facing bricks are the most popular type of brick and have been the façade material of choice in the UK for thousands of years, particularly in the housing market.
Engineering bricks have high compressive strength and low water absorption. They are used for their physical characteristics and not their appearance and are only classified by these properties.
Despite their name, common bricks are actually the least common brick types in the UK. They tend to have lower compressive strengths than facing bricks or engineering bricks and are generally lower quality.

After obtaining the needed materials, make sure you have a level surface to begin with.
Apply a “Toblerone”-shaped mortar to the leveled surface for the entire length of the wall.
Start laying bricks from one corner while applying mortar between two adjacent bricks.
Once you finished the entire length of the wall, repeat step two, considering the top surface of the first layer as the new leveled surface.

You will need approximately 38 bricks per foot length for an 8-foot wall if the bricks are the standard 7.5″ x 3.5″ bricks or 9.5″ x 2.75″ bricks with ²/₅” thick mortar joints.
However, larger bricks take up a larger area, and means fewer bricks overall.

You need approximately 120 kg (263 lbs) of cement for 1000 pieces of standard 9.5″ x 2.75″ bricks.
Additionally, you will need around 0.4 cubic meters (0.54 cubic yards) of sand to mix with your cement to make a 1:5 mortar mix for your brick wall.
