Worked example — bedding a patio
- 1Patio measures 4m × 2m = 8m², with bedding sand at 50mm.
- 2Volume: 8 × 0.05 = 0.4m³ = 400 litres of sharp sand.
- 3Sand weighs about 1.6 tonnes per m³, so that's roughly 640kg.
- 4One 850L bulk bag covers the job with plenty spare for the pointing mix.
Sand types and coverage guidance
- Sharp sand: bedding paving, floor screeds and rendering — coarse and strong.
- Building sand: brick and block laying mortar, mixed with cement.
- Kiln-dried sand: brushed into block paving joints once laying is finished.
- 1m³ = 1,000 litres and covers 20m² at 50mm deep.

Common questions
At 50mm deep, each square metre needs 50 litres — about 80kg — of sand. A standard 850L bulk bag therefore covers roughly 17m² at that depth. Enter your area above and the calculator converts it into litres, bags and tonnes for you.
