How Much Concrete for a 12x14 Patio?
For a 12x14 patio poured 4 inches thick, plan on about 2.07 cubic yards of concrete. That comes from 168 square feet times 0.333 feet of depth, divided by 27. How much concrete for a 12x14 patio at other thicknesses is in the table below.
Concrete calculator →The math for a 12x14 patio
- Area: 12 ft × 14 ft = 168 sq ft.
- Thickness in feet: 4 in ÷ 12 = 0.333 ft.
- Volume: 168 × 0.333 = 56.0 cubic feet.
- Cubic yards: 56.0 ÷ 27 = 2.07 yd³.
- With 10% extra: 2.28 yd³.
The concrete calculator runs the same steps for any size and thickness.

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
Four inches is standard for a patio that sees foot traffic and furniture. Slope it about 1/8 to 1/4 inch per foot away from the house so rain runs off, and go thicker under a hot tub or outdoor kitchen.

Ordering ready-mix
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.
Prep before the pour
Uneven ground is the main reason pours run short. Every half inch of extra depth across the patio adds concrete you did not plan for. Screed the base flat, check it with a string line and set the forms to finished height before the truck arrives.
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 patio that carries vehicles; fiber-reinforced mix is an option for light-duty slabs. Joints about 8 feet apart control where cracks form.
