Before you rely on this: First-pass guide only. Verify safety-critical or regulated work against the relevant standards, your project requirements and a qualified professional.
How to use this calculator
- Enter the length, width and depth.
- Press Calculate.
How it works
Volume = length × width × depth; weight ≈ volume × 1.6 tonnes per m³.
Worked example
5 × 5 × 0.1 m. = 2.5 m³ ≈ 4 tonnes.
Common mistakes
- Picking the wrong sand density — bedding, brickies' and fill sands differ in weight.
- Ordering exact volume; allow extra for compaction under pavers.
Frequently asked questions
How much sand do I need?
Multiply area by depth for volume, then by density (sand is roughly 1.5–1.6 tonnes per m³) to get the tonnage to order.
How much bedding sand under pavers?
A screeded bedding layer of about 25–30 mm is typical, over a compacted road-base sub-base.
Which sand density should I use?
Around 1.6 t/m³ for damp sand. Dry, wet or different sand types vary, so confirm the figure with your supplier.
