Brick Calculator - How Many Bricks Do You Need?

Our free brick calculator helps you work out how many bricks you need. Minimise waste and build in a more efficient way. Calculate bricks required for projects such as extensions, exterior walls, and more. Simply enter wall size, brick dimensions to get your estimates. Unsure about your brick sizes? Bricks and blocks tend to be available in standard sizes, making it much easier for consistency. Your average house brick size is 215mm x 65 mm x 102.5mm (length x height x width), which applies to most facing bricks. Blocks are often larger than bricks; standard concrete block and breeze block dimensions are usually 440mm x 215mm x 100mm (length x height x width). Although, blocks tend to be more varied depending on what you intend to use them for. It’s a good idea to get the measuring tape out to double-check your brick and block sizes to get an accurate estimate of brick quantities.
