How many concrete blocks per square meter of wall

For a standard 200 × 200 × 400 mm concrete block laid horizontally with a 10 mm mortar joint, the math is direct: a single block face is 0.21 m × 0.41 m ≈ 0.0861 m², so you need ≈ 11.6 blocks per m² of wall face. Add 5–10 % wastage and round up to 12.5 blocks per m².

For a 250 × 200 × 400 mm insulated block laid horizontally, the face dimensions are identical (0.21 m × 0.41 m) — wall thickness changes but blocks-per-m² of face does not. Same 12.5 blocks per m² target.
