Brick Calculator
Calculate how many bricks and how much mortar you need for a wall based on dimensions and brick size.
Bricks & Mortar Needed
Brick count is calculated from wall area divided by the face area of a single brick (including mortar joint).
Bricks = Wall Area / (Brick Length × Brick Height) (with mortar joints)
Standard brick sizes (with 3/8 in or 10 mm mortar joint):
- Standard: 8 × 2.25 in (203 × 57 mm) — ~6.75 bricks/sq ft (~73 bricks/m²)
- King: 9.75 × 2.75 in (248 × 70 mm) — ~4.8 bricks/sq ft (~52 bricks/m²)
- Queen: 9.75 × 2.75 in (248 × 70 mm) — ~4.8 bricks/sq ft (~52 bricks/m²)
Mortar estimate:
- Standard bricks: ~7 bags (70 lb) per 1,000 bricks
- King/Queen bricks: ~8 bags (70 lb) per 1,000 bricks
Imperial: Length and height in feet, area in square feet. Metric: Length and height in meters, area in square meters.
Always add 5–10% extra for breakage and cuts.
