Sand Calculator
Calculate sand volume in cubic yards and estimated tons for patios, pavers, and fill.
How to use
Enter length, width, and depth, set waste, then enter density from your supplier (or start from the planning default).
How the calculation works
Volume is computed like other bulk materials, then tons = adjusted cubic yards × density.
Formula
volume_ft³ = length_ft × width_ft × depth_ft; volume_yd³ = volume_ft³ ÷ 27; adjusted = volume_yd³ × (1 + waste%/100); tons = adjusted_yd³ × density_tons_per_yd³
Example calculation
A 10 ft × 10 ft area at 2 in deep is 16.67 ft³ (about 0.617 yd³) before waste. At 1.35 ton/yd³ → about 0.83 tons.
Assumptions
Shape
Simple rectangular volume
Material: sand · Key: geometry
Does not model slopes or trenches with varying depth.
Source: Geometric model
Default density (tons / yd³)
1.35 tons per cubic yard
Material: sand · Key: density
Dry sand is often planned near ~1.3–1.4 ton/yd³; moisture content changes weight significantly. Confirm with supplier. Treat masonry, concrete, and play sand as different materials when asking your supplier.
Source: Planning default — confirm with your product label or supplier quote. Not a lab or manufacturer certification.
Moisture
Not modeled
Material: sand · Key: moisture
Wet sand weighs more than dry sand at the same volume.

Practical notes
- Pavers and playground sand are different products — match the sand type to the job.
- Suppliers may quote by the ton or by the yard.
- Compaction and moisture change how far a load goes.
Limitations
- Density is a planning assumption, not a lab measurement for your load.
- Does not design structural bases or drainage.
- Planning estimate only.
FAQ
- Why is density editable?
- Different sands and moisture contents weigh differently. Estimated tons always depend on the density you use.
- Which sand density should I use?
- Ask your supplier for tons per cubic yard for the specific sand you are buying. The default is only a planning starting point.
