How much gravel for a 22x30 driveway: at 4 inches deep you need about 8.15 cubic yards, which is roughly 11.4 tons at 1.4 tons per yard. The driveway covers 660 square feet, so every inch of depth adds about 2.04 yards.

The math for a 22x30 driveway

Area: 22 × 30 = 660 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 660 × 0.333 = 220.0 cu ft.
Cubic yards: ÷ 27 = 8.15 yd³.
Tons: × 1.4 = 11.4 tons.

About gravel

Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 12.5 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the driveway as firm ground allows.

Good and poor uses for gravel

Best suited to:

Rural driveways and lanes where low upfront cost matters
Drainage areas and around downspouts
Temporary access while a site is under construction

Less suited to:

Steep slopes, where loose stone washes downhill
Spots plowed often, since plows push gravel into the lawn
Areas next to doors, because stone tracks inside

Quick reference numbers

Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.3 tons.
Another size for comparison: a 12x24 area at 3 inches takes about 3.7 tons.
Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
