Calculate how many bricks you need for any wall size. Choose from standard, modular, or Indian brick dimensions. Includes mortar volume and total material cost.
Indian standard bricks (190x90x90mm) with 10mm mortar joints require approximately 48 bricks per square metre for a single-brick wall. UK standard bricks require 60 per sq m, US bricks around 65 per sq m.
Multiply wall length by wall height to get area. Subtract door and window openings. Multiply by bricks per sq m for your brick size. Add 10% wastage. This calculator does all steps automatically.
A 10ft x 10ft (3x3m) wall = 9 sq m. With Indian standard bricks at 48/sq m: 9 x 48 = 432 bricks. Add 10% = 476 bricks to order.
The standard IS brick size is 190x90x90mm (modular) with 10mm mortar joints giving nominal dimensions of 200x100x100mm. Older bricks were 230x110x76mm.
Approximately 30% of a brick wall volume is mortar. For a standard 1:6 cement-sand mix, you need roughly 1 bag of 50kg cement per 0.3 cubic metres of mortar.
Use 10% wastage for standard rectangular walls. Use 15% for complex shapes, curved walls, or decorative brickwork. Always order slightly more than needed as batches can vary in colour.
