Volume and tonnage calculator →The math for a 24x70 driveway
- Area: 24 × 70 = 1,680 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 1,680 × 0.333 = 560.0 cu ft.
- Cubic yards: ÷ 27 = 20.74 yd³.
- Tons: × 1.55 = 32.1 tons.
The volume and tonnage calculator does this for any size.

About crusher run
The fines in crusher run fill the gaps between stones, so it weighs more per yard than clean stone once compacted. Plan on rolling or plate-compacting it in lifts. 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. Since the driveway carries car and truck traffic, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 35.4 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 crusher run
Good uses:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Think twice for:
- Drainage layers, since the fines slow water
- Decorative beds
- Spots where you want water to soak straight through
Quick reference numbers
- Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.8 tons.
- Another size for comparison: a 14x28 area at 2 inches takes about 3.8 tons.
- Weight used here: about 1.55 tons per cubic yard.
Mistakes that throw off the order
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
