Frequently asked questions
How many bricks do I need per square meter?
A standard single-leaf brick wall requires approximately 60 bricks per square meter, based on a standard brick size (215×102×65mm) with 10mm mortar joints.
How do I calculate bricks for a wall?
Multiply the wall length by height to get the area in square meters, then multiply by 60 for a single leaf wall or 120 for a double leaf wall. Add 10% extra for breakage and waste.
How many bricks are on a pallet?
A standard pallet typically holds around 500 bricks, though this varies by brick size and supplier.
What is the difference between single leaf and double leaf walls?
A single leaf (half-brick) wall is one brick wide — 102.5 mm with UK standard bricks. A double leaf (one-brick) wall is one brick length thick — 215 mm — with the two leaves bonded by header bricks, so it needs exactly twice the bricks per square meter. A cavity wall is different: two separate leaves with a gap, and the inner leaf is often blockwork.
