How much crushed stone for a 14x150 driveway: at 4 inches deep you need about 25.93 cubic yards, which is roughly 36.3 tons at 1.4 tons per yard. The driveway covers 2,100 square feet, so every inch of depth adds about 6.48 yards.
Volume and tonnage calculator →The math for a 14x150 driveway
- Area: 14 × 150 = 2,100 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 2,100 × 0.333 = 700.0 cu ft.
- Cubic yards: ÷ 27 = 25.93 yd³.
- Tons: × 1.4 = 36.3 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. Weight per yard is a planning number; the scale ticket at the yard is the real one.
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. For car and truck traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 39.9 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
Good uses:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Think twice 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 10x20 area at 4 inches takes about 3.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
