Default: 60 bricks/m², typical for UK standard bricks with mortar joints. This is a planning estimate. Use the exact coverage/yield stated by your manufacturer where available.

How to use this brick calculator

Enter your measured dimensions and replace any default coverage, density, pack size or yield with the value from the product you plan to use. The calculator applies your waste allowance and rounds purchase units up where appropriate.

What can change the estimate?

Actual quantities vary. Porous or rough surfaces can increase paint use; aggregate compaction affects gravel and sand; tile layouts create cuts; flooring patterns alter waste; and bagged products have manufacturer-specific yields. Treat the result as a starting point for purchasing rather than a guaranteed quantity.

Best practice: use manufacturer figures whenever they differ from the typical defaults shown here.

Frequently asked questions

Should I include extra material?

Usually, yes. An allowance can cover cuts, breakage, spillage and small measuring differences. The appropriate percentage depends on the material and project.

Are the default values exact?

No. They are general planning assumptions. Product formulations, dimensions and installation methods vary, so enter product-specific values whenever possible.

Can I use the result as a professional specification?

No. MaterialCoverage provides general planning estimates and does not replace manufacturer instructions, building regulations, engineering calculations or professional advice.
