How much crushed stone for a 22x150 driveway: at 4 inches deep you need about 40.74 cubic yards, which is roughly 57.0 tons at 1.4 tons per yard. The driveway covers 3,300 square feet, so every inch of depth adds about 10.19 yards.
Volume and tonnage calculator →The math for a 22x150 driveway
- Area: 22 × 150 = 3,300 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 3,300 × 0.333 = 1,100.0 cu ft.
- Cubic yards: ÷ 27 = 40.74 yd³.
- Tons: × 1.4 = 57.0 tons.

About crushed stone
Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size. 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. 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. 62.7 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.
Where crushed stone fits
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Poor fit for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 14x28 area at 4 inches takes about 6.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight 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.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
