Brick Calculator
Enter your room's dimensions and get an instant, accurate estimate of bricks, cement and sand — using the same formulas civil engineers use across India.
Room Dimensions
Wall & Brick Type
Typical for external / load-bearing walls.
IS 1077 standard modular size — most common on new construction across India.
Doors & Windows
Example: a standard door is about 3 ft wide × 7 ft tall. A standard window is about 4 ft wide × 4 ft tall. "How many" is how many of that exact size you have — e.g. 2 identical windows.

Common Questions
How many bricks are needed for a 10×10 room?
For a 10ft × 10ft room with 10ft high walls and a standard 9-inch modular brick wall, expect roughly 3,800–4,200 bricks before deducting doors and windows, or around 3,200–3,600 after typical openings. Use the calculator above with your exact door and window sizes for a precise number.
How many bricks per square foot for a 9-inch wall?
A 9-inch (229mm) wall built with standard modular bricks (190×90×90mm) needs approximately 10–11 bricks per square foot, including a 10mm mortar joint and typical wastage.
How many bricks are there in 1 cubic metre of brickwork?
Approximately 500 bricks per cubic metre for a standard 190×90×90mm modular brick with a 10mm mortar joint — the standard thumb rule used across Indian construction.
Is this calculator accurate enough for buying materials?
It's accurate for procurement planning and budgeting using standard formulas. For structural work or a final bill of quantities, confirm the numbers with a qualified civil engineer or your contractor.
