BRICKWORK
Brick Calculator: Bricks, Cement & Sand for a Wall
Calculate bricks, mortar, cement bags and sand for a 9-inch or 4½-inch wall. Modular and conventional Indian bricks, openings and wastage.
Assumptions used EDIT ▾
Commonly 1.27–1.33.
Brick count = wall volume ÷ volume of one brick including mortar joints. Mortar = wall volume − volume of solid bricks. Dry mortar volume is taken as wet volume × the dry factor, because sand and cement bulk before mixing. Cement is converted at 1,440 kg/m³ and 50 kg per bag. These are standard estimating conventions, not site measurements.
BRICKS NEEDED
1,834bricks
1,746 bricks for the wall + 5% wastage
- Wall volume150.9 cft
- 4.27 m³
- Mortar0.96 m³ wet
- 1.28 m³ dry
- Cement5.3 × 50 kg
- 6 bags
- Sand1.10 m³
- 39 cft
How it’s calculated
Bricks = wall volume ÷ (brick + joint) volume; mortar = wall − bricks; dry mortar = wet × 1.33
Example: A 20 × 10 ft, 9-inch wall ≈ 1,834 conventional bricks including 5% wastage.
Questions
How many bricks are in 1 m³ of brickwork?+
With modular 190 × 90 × 90 mm bricks and 10 mm joints, about 500. With conventional 230 × 110 × 75 mm bricks, about 410.
Which mortar mix should I use?+
Commonly 1:6 for 9-inch walls and 1:4 for 4½-inch walls, but follow the specification.
