Sand Calculator
Calculate how much sand you need by volume and weight, then turn the estimate into a bulk order or whole-bag purchase plan.
Sand Calculator
Sand estimate
Enter your project measurements to calculate sand volume and weight.
Choose measurements and sand density
Use finished project dimensions and the planned sand depth. Dry and wet choices return a range because sand density changes with moisture and grading; a supplier density gives one project-specific result.
How the sand calculation works
The calculator finds geometric volume first, then multiplies it by the selected density range. An optional ordering allowance is applied after the exact quantity so both values stay visible.
Ordering bulk sand or bags
Bulk quotes may be based on weight or volume. Bag planning rounds the upper weight estimate up to a whole bag, while also showing the theoretical low-to-high range.

For bedding sand and aggregate base in one workflow, use the paver base calculator. For pavers, base and bedding quantities together, use the paver project calculator.
FAQ
How deep should the sand layer be?
Use the depth specified for your application. Paver bedding, leveling, play areas and backfill have different requirements.
Why is sand weight shown as a range?
Moisture, particle size and packing change bulk density. The range makes that uncertainty visible instead of hiding it in one number.
Should I use dry, wet or supplier density?
Use supplier density when available. Otherwise choose the condition closest to the delivered sand and treat the result as a planning range.
