How Much Concrete for a 10x16 Patio?
How much concrete for a 10x16 patio depends on thickness. The patio covers 10 × 16 = 160 square feet, and at 4 inches thick that is about 1.98 cubic yards, or 2.17 yards with a 10 percent allowance. Mixed from bags, it is roughly 89 bags of 80 lb mix.
Concrete calculator →The math for a 10x16 patio
- Area: 10 ft × 16 ft = 160 sq ft.
- Thickness in feet: 4 in ÷ 12 = 0.333 ft.
- Volume: 160 × 0.333 = 53.3 cubic feet.
- Cubic yards: 53.3 ÷ 27 = 1.98 yd³.
- With 10% extra: 2.17 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.
Choosing the thickness
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.

Placing the order
A cubic yard of concrete is 27 cubic feet and weighs roughly 4,000 pounds. Most ready-mix trucks carry up to about 9 to 10 yards, though local trucks and rules vary. If your total is under a yard or two, bagged mix or a short-load supplier may be cheaper.
Prep before the pour
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.
Keeping cracks under control
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.
