Rock, soil, sand & mulch calculator

Measure beds and fill areas, calculate cubic yards, and optionally convert using supplier-provided density or bag volume.

Measure your project

Add separate sections for irregular spaces. Avoid overlaps. Use 10.5 ft for 10 ft 6 in.

Match your material

Use your plan, product label or supplier’s specifications.

Average depth (in) Supplier’s density (lb per cubic foot) Use the supplier’s figure for that material and condition. One cubic yard does not have a universal weight.Bag volume (cubic feet) Extra material allowance (%) Choose an allowance for your layout or supplier’s guidance. Zero adds no extra material.

Understand the number

How this estimate works

Measured area × depth in inches ÷ 324 gives cubic yards. US short tons = cubic feet × supplied density in lb per cubic foot ÷ 2,000. Bag counts use the volume on the bag and round up.

Match the material to its purpose

A decorative gravel bed, mulch layer, compacted base and fill area are different jobs. Ask for the material specification before comparing prices. Use the average depth over the area; irregular ground may need additional measurement. This calculator does not apply an assumed compaction or settling factor.

Compare delivered quantities in the same unit

Suppliers may quote by yard, ton, bag or load. Obtain the density for a weight conversion and the actual quantity for a load comparison. Moisture and material composition can change weight. Confirm delivery access, unloading location and whether spreading or compaction is included. Keep a delivery ticket so a later order can be compared with what arrived.
