Gravel Calculator – Accurate Estimator for Volume and Weight
Use this gravel calculator to determine the volume and weight of gravel needed for your project. Whether you're laying a new driveway, filling a garden bed, or creating a path, this tool will help you estimate exactly how much material you’ll need.
Features
- Supports both metric and imperial units
- Calculates volume in cubic yards or meters
- Estimates weight in tons or tonnes
- Gravel density options for loose, compacted, or dense materials
Formulas Used
Imperial: (L × W × D in ft) ÷ 27 = yd³; ft³ × density ÷ 2000 = tons
Metric: (L × W × D in m) = m³; m³ × kg/m³ ÷ 1000 = tonnes
Always round up slightly to account for compaction and surface unevenness. For best results, confirm density with your local supplier.
Common Gravel Calculator Use Cases
- Driveway installations and resurfacing
- Garden bed and planter fill
- Pathways and walkways
- Drainage and French drain systems
- Base layers for patios or sheds
- Erosion control and slope stabilization
Tips for Ordering the Right Amount of Gravel
- Always round up 5–10% to cover compaction and surface variations
- Double-check your required depth based on use case
- Know how your supplier prices (tons or cubic yards/meters)
- Confirm gravel type and density before ordering
Types of Gravel
| Gravel Type | Best For | Typical Size |
|---|---|---|
| Crushed Stone | Driveways, patios, and pathways | 1/4"–1" |
| Pea Gravel | Decorative gardens and walkways | ~3/8" |
| Road Base | Under pavers, heavy-use driveways | Mixed fine & coarse |
| Decomposed Granite | Natural paths, xeriscaping | Very fine |
| River Rock | Decorative landscaping, water features | 1"–3" |
Frequently Asked Questions
Q: How deep should gravel be for a driveway?
A: 3–4 inches is standard; deeper for heavy-duty use.
Q: What’s the difference between a ton and a cubic yard?
A: One cubic yard weighs roughly 1.4 to 1.7 tons, depending on type and moisture.
Q: Can I use this calculator for other materials?
A: Yes, but for more accurate estimates use our Sand Calculator or Stone Calculator.
Q: How many wheelbarrows make up a cubic yard?
A: Approximately 14–15 standard wheelbarrow loads.
