Estimate only.
Gravel is sold by the (short) ton or cubic yard. Weights use approximate densities that vary
with stone size, moisture, and compaction — order about 5–10% extra for spreading and
settling, and confirm tonnage with your supplier.
Adjust for your job
Lighter stone like pea gravel weighs a little less per yard; a driveway base goes deeper than a path. Change depth and stone type in the calculator, and order 5–10% extra for spreading.

What a 10 × 20 ft area is usually used for
A 10 × 20 ft strip is a common size for a walkway, a narrow side yard, a shed approach, or a ground-cover band beside a house. At 3 inches deep with crushed stone, the goal is usually an even, walkable surface that stays put rather than a load-bearing base.
How to decide
For a path or border at this size, decide whether a compacted base layer is needed underneath. On firm, well-drained soil a single 3-inch crushed-stone layer can be enough; on soft or wet ground, plan a deeper base and landscape fabric first. The calculator shows the surface tonnage, not the base, so add the base layer separately if your site needs one.
Checks before you order
- Confirm the soil drains and is firm enough to support the stone without fabric.
- Decide whether the 3-inch reference depth fits a path, border, or vehicle surface.
- Add 5–10% overage and confirm the supplier's ton or yard pricing before ordering.
FAQ
How much gravel for a 10 × 20 ft area?
At 3 inches of crushed stone, a 10 × 20 ft area needs about 2.50 tons (1.85 cubic yards, 50 cubic feet). A 4-inch driveway base needs about a third more — set your depth in the calculator.
How many cubic yards of gravel for a 10 × 20 ft area?
