Gravel Calculator
Calculate gravel volume and estimated weight from dimensions or a known area and depth.

Use the calculated quantity as a planning estimate and check supplier pack sizes or delivery conventions before ordering.
How it works
The calculator finds the project area, multiplies it by depth, and then applies the selected extra/waste percentage. Estimated weight, where provided, equals calculated volume × bulk density.
volume = area × depth × (1 + waste %)Worked example
For a 15 ft × 10 ft area at 2 in deep with 5% extra, the required volume is about 0.97 yd³ (26.25 ft³) before supplier-specific rounding.
Assumptions
- Volume includes the extra/waste percentage you enter.
- Weight uses a typical bulk-density value unless you enter your own density.
Limitations
- Loose materials settle and compact, so delivered quantity can differ from calculated loose volume.
- Bulk density varies with grading, moisture and compaction; confirm supplier data for ordering-critical work.
