Sand calculator
Work out sand for paving beds, levelling or mixes — volume, tonnes and bags with waste %.
Moisture changes mass a lot at the same volume. Treat results as a purchasing estimate. Also see gravel and cement in mortar.
Results
Enter data and click Calculate.
How results are calculated
V = length × width × depth × (1 + waste/100). Mass = V × density. Bags and bulk bags as for gravel.
Density stays in kg/m³ even with US length units — common for bulk deliveries. Mass is an estimate: moisture and compaction can change it.
How to use this calculator
- Enter the sand layer dimensions.
- Add waste % for uneven bases and spill.
- Choose dry / moist / wet or a custom density.
- Calculate volume, tonnes and optional cost.
Practical tips
- Paving bed: often about 30–50 mm over a compacted base.
- Moisture: if you buy by the tonne, match the preset to what the yard delivers.
- Small jobs: 25 kg bags can be easier than a loose load.
