Concrete calculator →The math for a 10x25 driveway
- Area: 10 ft × 25 ft = 250 sq ft.
- Thickness in feet: 5 in ÷ 12 = 0.417 ft.
- Volume: 250 × 0.417 = 104.2 cubic feet.
- Cubic yards: 104.2 ÷ 27 = 3.86 yd³.
- With 10% extra: 4.24 yd³.
The concrete calculator runs the same steps for any size and thickness.

How thick to pour it
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.

Ordering ready-mix
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.
Getting the ground ready
Under the slab, most residential pours sit on about 4 inches of compacted gravel. The base spreads the load, drains water away and keeps the driveway from cracking as the soil freezes and thaws. Compact the base in thin lifts, and dampen it just before the pour so it does not pull water out of the mix.
Joints, mesh and rebar
Plan the joints before the pour. Panels close to square crack less than long, narrow ones, and joint spacing around 12 feet is typical for a 4-inch slab. Cut joints with a groover while the concrete is soft or with a saw within the first day.
