Estimate cubic feet, cubic yards, tons, and whole bags for rectangular, round, or known square-foot sand beds using depth, density, waste, and bag volume.
20 ft x 10 ft x 2 in
Use the supplier density and the volume printed on the exact bag. Moisture, compaction, sand type, delivery minimums, and product coverage can change the purchase amount.

Sand estimates stay local. Moisture, compaction, supplier density, and bag labels can change what you buy.

Estimate sand volume for a sandbox or small base layer.
Convert cubic yards into estimated tons.
Round a cubic-foot estimate up to whole bags using the bag label volume.
Measure a round area or start from square feet without inventing rectangle dimensions.
Compare different depth assumptions.

Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
Use it when your task matches one of these common needs: Estimate sand for paver bedding or leveling. Estimate sand volume for a sandbox or small base layer. It works best when you already know the measurements, amounts, units, or options the page asks for.
In plain language: Area = length x width, pi x (diameter / 2)^2, or known square feet. Cubic feet = area x depth inches / 12. Add waste, divide by 27 for cubic yards, multiply by density for tons, and divide by bag volume before rounding up. The examples on the page are there so you can compare your inputs with a worked example before copying the answer.
Project area: a rectangular length and width, a round diameter, or an area already measured in square feet. Depth: the average sand depth in inches. Tons per cubic yard: the supplier density used to turn volume into weight. Bag volume: the cubic-foot volume printed on one bag, used to round the estimate up to whole bags. Waste percent: extra sand for leveling, spreading loss, compaction, and uneven areas.
Read the headline estimate first, then check the material, waste, coverage, and unit lines. For project tools, the supporting lines are often the difference between a rough idea and a list you can actually shop from.
Sand density and bag coverage change with moisture, sand type, compaction, supplier measurement, and product labeling. This is a material estimate, not a paver, pool, aquarium, or drainage specification. Also check the unit, scale, mode, and result limit because small input changes can change the answer.
It estimates a rectangular, round, or known-area sand layer in cubic feet, cubic yards, tons, and whole bags. Enter the area measurements, depth, density, bag volume, and waste percent.
Yes for a bedding or leveling layer. Use Rectangle or Known area, then keep base gravel, edge restraints, slope, compaction, and polymeric joint sand as separate checks.
Yes. Choose Rectangle or Round area, enter the inside measurements and fill depth, then use the volume printed on the play-sand bag before buying.
Yes. Enter the cubic-foot volume printed on one bag. The calculator divides the adjusted cubic feet by that bag volume and rounds up to a whole bag. Product coverage can still differ, so check the label.
Use Rectangle or Round area for a simple sand base when you know the depth and density. This does not calculate pool water, filter specifications, or installation requirements.
Use Rectangle for a rough bed-volume estimate after converting tank dimensions to feet. Enter the aquarium-sand bag volume when listed, then check the product label and tank guidance.
Water adds weight and packed sand can settle differently. That is why the tons-per-cubic-yard input matters more than one fixed internet number.
Yes. Choose Round area and enter the inside diameter in feet. The calculator uses pi times the radius squared before applying depth, waste, density, and bag volume.
