Brick Count Estimator
Calculate bricks, mortar volume, sand, and cement needed for masonry walls.
Masonry Wall Settings
Estimated Brick and Mortar Totals
- Standard UK stretcher layout requires ~60 bricks per m² for a single skin wall including joints. Double skin (cavity or solid) requires exactly double that density (~120 per m²).
