Knowing the standard UK brick sizes is essential when working with reclaimed bricks or planning a construction project. Whether you’re involved in a DIY renovation or a large-scale build, understanding brick dimensions ensures accurate material calculations, correct mortar usage and helps streamline your planning process.
In this guide, we’ll address some of the most common questions you might have when working with bricks:
- What are the standard UK brick sizes?
- Why is it important to know brick dimensions for construction?
- How do brick sizes affect mortar calculations?
- What factors should be considered when estimating the number of bricks needed for a project?
Standard UK brick sizes
In the UK, bricks typically follow a standard size to ensure consistency in construction. This section will go through the standard brick sizes to help you with your projects.
Length: 215 mm
Width: 102.5 mm
Height: 65 mm
(LxWxH) 215 x 102.5 x 65 mm
These measurements are applied to most traditional bricks, including clay and concrete.

Adding Mortar Joints
When calculating brick sizes in construction, it’s crucial to account for the mortar joints between each brick. The standard mortar joint is typically 10 mm thick, which impacts the overall dimensions when calculating wall coverage.
So, when accounting for the mortar, the brick dimensions will increase by 10 mm:
Length: 225 mm
Width: 112.5 mm
Height: 75 mm
Calculating Bricks for a Wall
Now that you understand the brick sizes (including the mortar), let’s break down the steps to calculate the number of bricks needed for your wall.
Step 1: Measure the Wall Area
This step requires calculating the total area of the wall in square meters by measuring the height and length.
Example: for a wall that is 3m high and 5m long, the wall area would be 3 × 5 = 15 m²
Step 2: Calculate Each Brick Covers
Next, calculate the area that a single brick will cover, including mortar:
- Use the brick’s standard length (including mortar), which is 0.225 m (225 mm)
- Use the brick’s standard height (including mortar,) which is 0.075 m (75 mm)
- Multiply these two values together to find the total area one brick covers
Brick Area = 0.225 × 0.075 = 0.016875 m²
Step 3: Calculate the Number of Bricks
Now, divide the total wall area by the area each brick covers:
Bricks Required = 15 ÷ 0.016875 = 889 bricks
Step 4: Account for Wastage
Adding 5-10% extra bricks is a smart way to cover wastage due to cuts, breakage or mistakes.
889 bricks + 10% = 978 bricks (rounded up)
Tips for Calculating Special Brick Types
- Reclaimed bricks: Since older bricks may vary slightly in size, measuring a sample brick could be beneficial to help adjust the calculations accordingly
- Decorative Feature: For patterns such as herringbone or basketweave, account for the layout changes that may require additional bricks.
