Bricks for a 5 × 2 m wall
A wall about this high is a garden boundary or privacy wall. A freestanding wall over about 1 m needs piers or an engineer's advice, and walls next to a highway or over 2 m may need planning permission. This wall is 10 m². Counts are for standard bricks (215 × 102.5 × 65 mm) with 10 mm joints, and the mortar is a 1:4 cement to building sand mix.
| Wall thickness | Bricks | Packs of 500 | Building sand (tonnes) | Cement (25 kg bags) |
|---|---|---|---|---|
| Single skin (half-brick, 102.5 mm) | 630 | 1.3 | 0.56 | 6 |
| One brick thick (215 mm) | 1,260 | 2.5 | 1.12 | 11 |
How much to allow for waste
Cuts and breakage use up bricks. Use 5% for a plain straight wall, 10% for most jobs, and 15% where there are piers, corners or patterned work (single skin).
| Waste | Bricks | Packs of 500 | Building sand (tonnes) | Cement (25 kg bags) |
|---|---|---|---|---|
| 0% | 600 | 1.2 | 0.53 | 5 |
| 5% | 630 | 1.3 | 0.56 | 6 |
| 10% | 660 | 1.3 | 0.59 | 6 |
| 15% | 690 | 1.4 | 0.61 | 6 |

Frequently asked questions
How many bricks do I need for a 5m x 2m wall?
A 5 × 2 m wall is 10 m². In a single skin of standard bricks (60 per m²) you need 630 bricks including 5% for cuts and breakage. Without any allowance it is 600. A wall one brick (215 mm) thick needs 1,260.
How much sand and cement for a 5m x 2m brick wall?
About 0.56 tonnes of building sand and 6 bags of 25 kg cement for a single skin, using a 1:4 mix and a rule of thumb of about 0.9 tonnes of sand and 8 bags of cement per 1,000 bricks. Your mix and joint depth will change it.
How many packs of bricks is a 5m x 2m wall?
1.3 packs of 500 for a single skin, so order 2 packs. Buy the whole job together, because colours vary between batches.
