Calculate how much gravel you need for your driveway, path, or landscaping project with our free gravel calculator, including weight and volume estimates.
Volume = Length × Width × Depth. This is then converted to weight using gravel's typical density (approximately 1.4-1.7 tons per cubic yard, depending on gravel type), since gravel is commonly sold by weight.
This depends on use, driveways commonly use 4-6 inches, while decorative paths might use 2-3 inches, check project-specific recommendations.
Different gravel types (crushed stone, pea gravel, river rock) have different densities based on particle size and composition, affecting how much a given volume weighs.
Yes, ordering 5-10% extra accounts for settling, uneven ground, and compaction that reduces the effective covered depth over time.
Most suppliers sell gravel by weight (tons), though some smaller quantities may be sold by volume (cubic yards), confirm with your specific supplier.
