The math for a 22x120 driveway

Area: 22 × 120 = 2,640 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 2,640 × 0.333 = 880.0 cu ft.
Cubic yards: ÷ 27 = 32.59 yd³.
Tons: × 1.4 = 45.6 tons.

About gravel

Because ’gravel’ covers so many products, the weight per yard moves with stone size and how much fine material is in the pile. Rounded stone with no fines rolls under tires; crushed stone with fines locks together. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

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. 50.2 tons may take more than one 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.

When to choose gravel

Works well for:

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

Poor fit for:

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 4 inches takes about 5.0 tons.
Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
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.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
