Gravel is sold by the cubic yard or by the ton; most gravel weighs roughly 1.4 tons per cubic yard, though this varies by stone type and moisture. For driveways, a 3–4 inch layer is typical over a compacted base. Order a little extra for settling and edges.
How it’s calculated
This calculator returns its result directly from the values you enter using standard arithmetic for this calculation; all figures are estimates for general information.
Results update as you type and are estimates, not professional advice — verify important decisions with a qualified professional.
Worked example
A 20x10 area 3 inches deep needs about 1.85 cubic yards, roughly 2.6 tons of gravel.
Common mistakes
- Confusing cubic yards with tons — weight depends on the stone.
- Skipping extra for settling and a compacted base.
Where it is used
- Ordering gravel for a driveway, path, or base layer.
- Converting volume to tons for delivery pricing.
Frequently asked questions
How deep should gravel be?
Walkways often use 2–3 inches; driveways 4–6 inches, sometimes in multiple layers over a base.
Cubic yards or tons?
Suppliers quote both. Use cubic yards for volume; tons depend on the specific stone's density (about 1.4 tons per yard is a common estimate).
Should I add extra?
Yes — 5–10% covers settling, uneven ground, and spillage.
