About this calculator
Sand for paver bedding, pipe beds, sandpits and mixes, by volume and weight.
How it’s calculated
Volume = area × depth. Weight = volume × about 1.6 t/m³ (about 1.6 t per m³).
Worked example
With these inputs:
- Area shape
- Rectangle
- Length
- 6 m
- Width
- 3 m
- Depth
- 50 mm
- Material
- Concrete sand
- Extra for settling / compaction
- 10%
the result is:
- Volume
- 0.99 m³
- Area
- 18 m²
- Approx. weight
- 1.58 t
- To order
- 1 cube (rounded up to half cubes)
Tips from the trade
- Wet sand is heavier. Delivered weight can be 10–20% more than dry.
