How to Calculate Fill Dirt Volume
Most landscaping suppliers sell fill dirt by the cubic yard. To convert your project area to cubic yards, use this formula:
Our calculator also multiplies your cubic yard result by 1.25 tons/yd³ (the standard density for fill dirt) to show estimated weight — essential if you are hauling the material yourself or need delivery pricing.
Pro Tips & Insights
Fill dirt contains subsoil and rocks. Do not use it as the top layer for growing plants; cap it with 4-6 inches of screened topsoil.
Always order 20% extra fill dirt to account for heavy compaction.
When filling deep holes, compact the dirt every 4 to 6 inches to prevent future sinking and settling.
