How Much Concrete for a 10x80 Driveway?
For a 10x80 driveway poured 5 inches thick, plan on about 12.35 cubic yards of concrete. That comes from 800 square feet times 0.417 feet of depth, divided by 27. How much concrete for a 10x80 driveway at other thicknesses is in the table below.
Concrete calculator →The math for a 10x80 driveway
- Area: 10 ft × 80 ft = 800 sq ft.
- Thickness in feet: 5 in ÷ 12 = 0.417 ft.
- Volume: 800 × 0.417 = 333.3 cubic feet.
- Cubic yards: 333.3 ÷ 27 = 12.35 yd³.
- With 10% extra: 13.58 yd³.
The concrete calculator runs the same steps for any size and thickness.

Concrete for a 10x80 driveway by thickness
| Thickness | Cubic feet | Cubic yards | Yards +10% | 80 lb bags | 60 lb bags |
|---|---|---|---|---|---|
| 4 in | 266.7 | 9.88 | 10.86 | 445 | 593 |
| 5 in | 333.3 | 12.35 | 13.58 | 556 | 741 |
| 6 in | 400.0 | 14.81 | 16.30 | 667 | 889 |
Bag counts assume about 0.60 cubic feet per 80 lb bag and 0.45 per 60 lb bag, rounded up.
Thickness for this job
Residential concrete driveways are usually 4 to 6 inches thick. Five inches is a sensible minimum if a pickup or delivery truck uses it, and 6 inches if heavier vehicles or an RV park on it. The apron at the street often gets the thicker section.

Placing the order
Concrete is ordered by the cubic yard, and a yard is 27 cubic feet. Ready-mix plants usually sell in quarter- or half-yard steps, so round up to the next step rather than down. Running short in the middle of a pour leaves a cold joint, which is a weak seam in the driveway.
Prep before the pour
Prep matters as much as the yardage. Strip sod and soft soil, compact the subgrade, then add a compacted stone base, commonly about 4 inches. A level, firm base also keeps your thickness even, which keeps the yardage close to the math.
Joints and reinforcement
Cut or tool control joints so the slab cracks where you want it to. A common rule is spacing them, in feet, at no more than two to three times the slab thickness in inches, so about 12 feet apart for a 4-inch slab, and about a quarter of the slab depth deep.
