How this is calculated
Gravel is sold by weight, not just volume, so this tool bridges both: Volume = Length × Width × Depth. We convert depth from inches to feet, calculate cubic feet, then convert to cubic yards (÷27) and round up to the nearest quarter yard. Weight is estimated at 1.4 tons per cubic yard, a common density for standard crushed gravel and sand — the figure most suppliers use to quote and deliver by the ton.
FAQ
Multiply the area by your desired depth to get volume in cubic yards, then convert to tons using roughly 1.4 tons per cubic yard. Most suppliers sell and deliver gravel by the ton, so this is the figure to bring when you call for a quote.
Typically 2 to 4 inches for walkways and decorative areas. Driveways usually need 4 to 6 inches over a compacted base, often in two layers — a coarser base for drainage, topped with a finer decorative layer.
Slightly — this calculator uses about 1.4 tons per cubic yard for gravel. Sand runs a bit heavier, typically 1.4 to 1.6 tons per cubic yard depending on moisture. Check with your supplier for the exact density of your material.
Yes, for most paths and driveways. Landscape fabric laid before the gravel prevents weeds from growing through and stops the gravel from sinking into the soil over time, keeping the surface cleaner with less maintenance.
Common Mistakes to Avoid
Skipping the landscape fabric layer — without it, gravel slowly sinks into the soil and weeds grow up through it.
Not compacting each layer when building up a driveway in multiple lifts.
Pro Tips
Use angular crushed gravel rather than smooth river rock for driveways and paths — it locks together and stays put underfoot.
Edge the area with pavers or metal edging to stop gravel from migrating into the lawn.
