How Much Concrete for a 14x25 Driveway?
For a 14x25 driveway poured 5 inches thick, plan on about 5.40 cubic yards of concrete. That comes from 350 square feet times 0.417 feet of depth, divided by 27. How much concrete for a 14x25 driveway at other thicknesses is in the table below.
Concrete calculator →The math for a 14x25 driveway
- Area: 14 ft × 25 ft = 350 sq ft.
- Thickness in feet: 5 in ÷ 12 = 0.417 ft.
- Volume: 350 × 0.417 = 145.8 cubic feet.
- Cubic yards: 145.8 ÷ 27 = 5.40 yd³.
- With 10% extra: 5.94 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.

Placing the order
Ready-mix is priced and batched by the cubic yard (27 cubic feet). Plants commonly add a small-load fee when an order is under a set minimum, so ask about it when you call. Ordering a little extra costs far less than a second truck.
Base and forms
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 and reinforcement
Reinforcement does not stop cracks, but it holds them tight. Wire mesh or rebar set mid-depth on chairs is common for a driveway that carries vehicles; fiber-reinforced mix is an option for light-duty slabs. Joints about 8 feet apart control where cracks form.
