Gravel Calculator
Estimate gravel volume and weight for rectangular or circular areas. Editable density with cubic yard, ton, and metric tonne outputs.
Formula
Volume = area × depth. Weight = volume × density. US short tons = pounds ÷ 2000.
Assumptions
- Default density is an editable estimate, not a universal constant.
- Waste percentage accounts for compaction and spillage.
Limitations
- Actual weight varies with moisture and compaction.
- Does not model delivery minimums or material pricing.
Worked example
20 ft × 10 ft area, 4 in deep
Volume ≈ 66.67 cu ft ≈ 2.47 cu yd. At 100 lb/ft³, weight ≈ 6,667 lb ≈ 3.33 tons.
Frequently asked questions
What density should I use?
Gravel density varies by material, particle size, moisture, and compaction. A default near 100 lb/ft³ is a starting estimate — adjust for your material.
