Paver bedding is often 1 in; sandbox fill is deeper.

Density (tons/yd³)
i
Density

Dry play/mason sand is often ~1.3–1.4 tons per cubic yard. Damp sand is heavier.

Waste (%)
i
Waste

Compaction and irregular edges. 10% is a common adder.

How to use this calculator

  1. Enter area.
  2. Set depth.
  3. Use the supplier’s tons/yard if they sell by weight.
  4. Add waste for compaction.

Results explained

Same volume math as gravel or topsoil with a sand density default. Paver count is the paver calculator; this page is the sand bed.

Quick reference: sand

1 cubic yard covers about 162 sq ft at 2 inches.

1 in over 100 sq ft≈ 0.31 yd³

Polymeric joint sand is sold by the bag — not this bulk volume.

How the estimate is built

cu yd = (sq ft × inches) ÷ 324, then × (1 + waste%). Tons = yards × density.

Example scenario

200 sq ft × 2 in with 10% waste ≈ 1.36 yd³1.8 tons at 1.35 t/yd³.

FAQ

Gravel instead?

Use the gravel calculator and a stone density.

Bags?

Divide ordered yards × 27 by bag cubic feet.

Play vs masonry sand?

Volume is the same; spec the product with your supplier.
