How Much Concrete for a 14x16 Patio?
How much concrete for a 14x16 patio depends on thickness. The patio covers 14 × 16 = 224 square feet, and at 4 inches thick that is about 2.77 cubic yards, or 3.04 yards with a 10 percent allowance. Mixed from bags, it is roughly 125 bags of 80 lb mix.
Concrete calculator →The math for a 14x16 patio
- Area: 14 ft × 16 ft = 224 sq ft.
- Thickness in feet: 4 in ÷ 12 = 0.333 ft.
- Volume: 224 × 0.333 = 74.7 cubic feet.
- Cubic yards: 74.7 ÷ 27 = 2.77 yd³.
- With 10% extra: 3.04 yd³.
The concrete calculator runs the same steps for any size and thickness.

How thick to pour it
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.
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 patio 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
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.
