Brick & Mortar Calculator

The most common Bangladesh standard brick is 9.5 × 4.5 × 2.75 inches (241 × 114 × 70 mm). First-class bricks are well-burnt and slightly smaller at 228 × 108 × 69 mm. This calculator includes both sizes plus global brick standards (UK, US, Indian, AAC blocks).

For a 9-inch (full brick) wall with standard BD bricks and 12mm mortar joints: approximately 10–11 bricks per square foot. For a 4.5-inch (half brick) wall: approximately 5–6 bricks per square foot. This calculator gives exact numbers based on your wall dimensions and brick type.

1:6 cement to sand ratio (1 part cement to 6 parts sand) is the most common for general brickwork in Bangladesh. For load-bearing walls or areas with heavy rain exposure, 1:4 or 1:5 is used. For non-structural partition walls, 1:8 is acceptable.

First-class bricks in Dhaka: ৳12–18 per piece. Second-class: ৳9–13. Prices vary by location — bricks are cheaper near kilns in Gazipur, Savar, and Narayanganj. Enter your current supplier price for an accurate cost estimate.

AAC (Autoclaved Aerated Concrete) blocks are lightweight, pre-made blocks used as an alternative to traditional bricks. They offer better thermal insulation, faster construction, and less mortar usage. They are gaining popularity in Bangladesh for commercial and mid-to-high-end residential projects.
