Brick Quantity Calculator
Estimate the blocks, cement, and sand your project needs — before you order.
How it's calculated
Wall area = length × height
Block face with 10 mm joint = (0.39 + 0.01) × (0.19 + 0.01) = 0.08 m² → 12.5 blocks per m²
Blocks = area × 12.5 × (1 + wastage%)
Mortar volume = wall volume − block volume ≈ 7.4% of (area × block thickness), plus 33% extra as dry volume
Cement (1:5 mix) = dry mortar ÷ 6 ÷ 0.0347 m³ per 50 kg bag
Sand = dry mortar × 5 ÷ 6
How it's calculated
Blocks = area × blocks-per-m² × (1 + wastage%)
Uni / Cobel cover ~50 per m²; Eliyana ~100 per m².
Bedding sand = area × 0.05 m (compacted 50 mm sand bed)
Disclaimer: These results are estimates only, based on standard block sizes, a 10 mm mortar joint, and typical site conditions. Openings (doors, windows), site wastage, and workmanship vary — always confirm final quantities with your contractor or our sales team before ordering.
