Sand Calculator
Estimate sand volume, weight and material cost.

Volume is the reliable starting point; sand weight is only as good as the density you enter
Sand is ordered for bedding, fill and leveling in both volume and weight units, but its bulk density changes with grading, moisture and compaction. This calculator first determines the geometric volume of the layer from area and depth. It can then estimate weight using the density you provide. Keep those two outputs conceptually separate: the volume describes space, while the weight is an approximation tied to a particular bulk condition.
Installed volume from area × depth.
Depends on the bulk-density value entered.
Loose delivered sand may occupy a different volume from the compacted finished layer.
How to use the Sand Calculator
- Measure the area receiving sand and the intended finished depth.
- Convert depth to the same unit system as the area dimensions.
- Calculate the raw layer volume, then apply a project-specific allowance if loose-to-compacted behavior or grade irregularity justifies it.
- Use a supplier/product bulk density for approximate weight and compare the result with delivery or bag options.
Why density is editable
Dry loose sand and moist compacted sand do not weigh the same per cubic unit. The calculator does not hide that uncertainty behind one universal density.
Use volume to order, weight to plan logistics
Ask the supplier how the material is sold and what density or conversion they use. The weight output is especially useful for comparing delivery limits, not for pretending every load is identical.
Worked example: 2 in bedding layer
- Area
- 300 sq ft
- Depth
- 2 in = 0.167 ft
- Volume
- ≈ 50 cu ft
- Density
- Entered from supplier/product
The geometric layer is about 50 cubic feet. The tonnage changes with the density input, and extra loose material may be needed if the finished layer will be compacted.
Practical planning tips
Measure the prepared base rather than the original ground if grading changes the actual sand depth.
Use a supplier density for the specific sand when weight matters; masonry sand, fill sand and wet sand can differ.
If the layer is compacted, distinguish the required finished thickness from the loose-delivery volume.
Calculate bedding and jointing sand separately on paver projects because they use different depths and often different products.
Common mistakes to avoid
Using an average sand density as though it were an exact truck weight.
Entering inches of depth as feet.
Adding a compaction allowance twice—once to depth and again as waste.
Combining different sand products into one density/cost estimate.
Sand Calculator FAQs
How do I convert sand volume to tons?+
Multiply volume by a reasonable bulk density for the actual sand and condition, then convert the resulting weight to tons. Supplier data is preferable to a generic value.
Why does moisture matter?+
Water adds weight and can change bulk behavior, so the same geometric volume of sand can weigh differently when wet.
Should I add extra for compaction?+
Only when the project requires a compacted finished layer and the supplier/product guidance indicates more loose material is needed. Keep the assumption explicit.
Can I use this for paver bedding sand?+
Yes for the bedding layer if you enter the correct area, depth and material data. Jointing sand should be estimated separately.
