How to estimate fill dirt volume
Measure the area and required fill depth, then calculate cubic yards. For rectangular fill zones, use length in feet × width in feet × depth in inches ÷ 324.
If ground elevations vary across a site, a single average depth may misrepresent the job. Use surveyed sections or an appropriate earthwork calculation method when accuracy matters.
Loose, bank and compacted soil volume
Excavated soil can swell when loosened and shrink when compacted. Bank cubic yards, loose cubic yards and compacted cubic yards are different states. Convert using project-specific factors rather than one universal rule.
Backfilling and compaction
Fill material may need placement in controlled lifts and specified compaction to meet construction requirements. The amount delivered must take settlement and compacted density into account when the project specifies a final grade.
When professional measurement is needed
Retaining walls, structural fill, major grading and drainage work can require engineered design, surveys and geotechnical specifications. A simple volume calculator is a planning tool, not a substitute for those services.
Frequently Asked Questions
How many yards of fill dirt cover 300 sq ft at 6 inches?
The geometric volume is approximately 5.56 cubic yards.
Does delivered loose fill equal compacted fill?
Not necessarily. Compaction changes bulk volume, and the relationship depends on the specific soil.
