Gravel Calculator
Gravel is sold by the yard and the ton, so you need both numbers. Enter your area and depth to get the volume and weight for a driveway, path or drainage bed.

Why use the Gravel Calculator
Gravel is sold by both the yard and the ton. This gives both numbers so you order and price it right.
How to get your numbers
- Area (length × width, or total sq ft).
- Depth in inches.
- Driveways need a deeper, layered base than paths.

How to use it
- Enter the length and width, or a total area.
- Enter the depth — 2–3 inches for paths, more for driveways.
- Order about 10% extra for compaction.
Frequently asked questions
How much gravel do I need?
Multiply area (sq ft) by depth in feet for cubic feet, then divide by 27 for cubic yards. Gravel weighs about 1.4 tons per cubic yard.
How deep should gravel be?
About 2 inches for walkways and 4–6 inches (installed in layers) for driveways over a compacted base.
How many tons are in a cubic yard of gravel?
Roughly 1.4 tons, though it varies with stone size and moisture.
What size gravel should I use?
Crushed stone with fines (like ¾-inch minus) compacts firmly for driveways and bases; clean pea gravel suits paths and drainage.
Is it cheaper to buy gravel in bags or bulk?
Bulk (by the yard or ton) is far cheaper for anything larger than a small patch — bags only make sense for tiny jobs.
Do I need landscape fabric under gravel?
A woven fabric under the gravel blocks weeds and keeps stone from sinking into the soil, extending the life of the surface.
How much gravel do I need for a driveway?
Calculate the area and use a 4–6 inch total depth, installed in compacted layers. Enter your dimensions above for the yardage and tonnage.
