How this calculator works
Measure actual field dimensions and add waste for cuts or overlap.
For best results, measure actual jobsite dimensions, use supplier-specific coverage numbers, and choose a waste factor that matches layout complexity and field conditions.
Real-world estimating notes
Bulk materials vary by density, moisture, supplier, and compaction. Use this calculator for planning, then confirm tonnage or yardage with the local yard before ordering.
Before ordering
- Check whether the supplier sells by ton, cubic yard, or bag.
- Increase allowance where compaction matters.
- Confirm delivery minimums before ordering.
