🧱 Brick Calculator

Bricks per m² = 1 / ((Brick L + Joint) × (Brick H + Joint)) With Indian brick (230×75mm) and 10mm joint: = 1 / ((0.230 + 0.010) × (0.075 + 0.010)) = 1 / (0.240 × 0.085) = 1 / 0.0204 = 49 bricks/m² (half brick wall) For single brick wall (230mm thick): Double the bricks per m²: ~98 bricks/m² Common values (Indian Standard brick, 10mm joint): Half brick (110mm): ~49 bricks/m² Single brick (230mm): ~98 bricks/m² Double brick (350mm): ~147 bricks/m²

Mortar Volume = Wall Volume × 0.25 to 0.35 (mortar fills joints and voids between bricks) Dry volume of mortar = Wet volume × 1.30 For 1:6 mix (per m³ dry mortar): Cement = (1/7) × 1.30 = 0.186 m³ = 6 bags (50kg) Sand = (6/7) × 1.30 = 1.11 m³ For wall area (per m², single brick, 10mm joint): Mortar ≈ 0.033 m³ → ~0.2 bags cement (1:6) ≈ 0.042 m³ → ~0.3 bags cement (1:4)

Indian Standard (IS 1077): 190 × 90 × 90 mm (nominal with joint) 230 × 110 × 75 mm (actual size, most common) ~49 bricks/m² at 10mm joint (half-brick wall) Modular (IS size): 190 × 90 × 90 mm ~53 bricks/m² at 10mm joint Jumbo / Wire-cut: 300 × 150 × 100 mm ~33 bricks/m² Fly ash brick (common in India): 230 × 110 × 75 mm (same as standard) Lighter weight, better insulation
