How To Use Brick Calculator Tool
The Brick Calculator tool is designed to provide you with an accurate estimate of how many bricks you need for your wall project. Here’s a step-by-step summary on how to use it correctly:
1. Input the total length and height of your wall in meters. These values are used to calculate the wall’s overall area.
2. If your wall includes windows, doors, or any openings, enter the total area of these features in square meters. This amount is subtracted from the overall wall area to ensure you’re not overestimating the brick requirement.
3. Choose whether your wall is a Single Skin or Double Skin. For double skin walls, the tool automatically doubles the brick count since two layers of bricks are required.
4. Once all fields are completed and you click the Calculate button, the tool computes the number of bricks required. This calculation takes into account the effective wall area (after deducting openings), the brick face area, a contingency of 10% for waste, and doubles the result if the wall is double skin.
5. If you need to clear the inputs or start over, click the Reset button to clear all fields and the displayed result.
By following these steps, you ensure that the tool accurately reflects your specific wall and brick details, giving you a reliable estimate for your construction project.

How many bricks per square meter?
As a guide, you need around 60 bricks per m2 for a single layer (or half brick) wall, or 120 bricks per m2 for a two layer (one brick) wall. Multiply the wall length by height to get the area, then multiply that by 60 to get the quantity of bricks you need - plus an extra 5%-10% for wastage.
Remember that this estimate is based on a standard-sized brick. Be sure to measure the exact size of your brick first. A standard UK brick size is (LxWxH) 215 x 102.5 x 65mm, but depending on the type you use, the size can vary.
To make your brick estimate easier, use our brick wall calculator to work out the quantity of bricks or blocks you'll require for any project. Whether you're building a wall, a new extension or a brick barbeque, we'll help you cut down on waste and avoid over-spending on building materials.
Do I need Metric or Imperial Bricks?
The difference between imperial and metric brick sizes plays an important role in both the aesthetics and practicality of construction. Imperial bricks, typically used in older buildings, measure 3 inches by 9 inches by 4.5 inches, providing a larger and more robust appearance. In contrast, modern metric bricks have a standardized size of 65mm high, 215mm long and 102.5mm wide, making them more uniform and easier to work with for contemporary building practices. The switch from imperial to metric bricks happened over time due to standardisation, but the original imperial bricks continue to be sought after in renovation projects.
Imperial bricks have distinct qualities that make them popular in restoration and conservation projects. Their larger size gives them an imposing and traditional look, which is especially valued in the restoration of historic buildings. As they were often made by hand, imperial bricks tend to have a more textured, characterful appearance, making them ideal for projects requiring authenticity and charm. Many homeowners and builders prefer to use these older bricks in projects where the goal is to maintain the integrity and style of traditional construction. Common Imperial Brick sizes are 75mm x 230mm x 110mm and 68mm x 228mm x 108mm.
Metric bricks measure 65mm x 215mm x 102.5mm, they are designed to be consistent in size and often made by machines, though there are a small number of genuine handmade metric bricks on the market. Their smaller dimensions allow for more efficient transportation and are easier to handle for the bricklayer. The standardised size also simplifies building techniques and reduces the likelihood of gaps or inconsistencies in the brickwork. Despite this, the demand for imperial bricks continues, especially in areas where heritage and historical accuracy are paramount, such as barn conversions, period homes, and conservation areas.

How much cement will I need?
How much cement will I need?
To work out how much mortar you need, measure the area size of the wall you're building, the sand-to-cement ratio you'll use and the mortar joint thickness. As a guide, you need approx. 120 kg of cement per 1000 standard sized bricks, plus 0.4 m3 of sand for a 1:5 mortar mix. Some ready-to-use mortar states on the label the number of bricks it lays.

How many bricks are required for 1m3 of brick work?
How many bricks are required for 1m3 of brick work?
Approximately 500 bricks are required for a 1 cubic metre of brick wall. This is based on a 10mm mortar joint and a standard UK brick size. You may want to add an additional 5% more for wastage, which would mean you'll need to order 525 bricks, and if the brick size is smaller you'll also require more.
