How Much Concrete for a 14x60 Slab?
For a 14x60 slab poured 4 inches thick, plan on about 10.37 cubic yards of concrete. That comes from 840 square feet times 0.333 feet of depth, divided by 27. How much concrete for a 14x60 slab at other thicknesses is in the table below.
Concrete calculator →The math for a 14x60 slab
- Area: 14 ft × 60 ft = 840 sq ft.
- Thickness in feet: 4 in ÷ 12 = 0.333 ft.
- Volume: 840 × 0.333 = 280.0 cubic feet.
- Cubic yards: 280.0 ÷ 27 = 10.37 yd³.
- With 10% extra: 11.41 yd³.
The concrete calculator runs the same steps for any size and thickness.

Concrete for a 14x60 slab by thickness
| Thickness | Cubic feet | Cubic yards | Yards +10% | 80 lb bags | 60 lb bags |
|---|---|---|---|---|---|
| 4 in | 280.0 | 10.37 | 11.41 | 467 | 623 |
| 5 in | 350.0 | 12.96 | 14.26 | 584 | 778 |
| 6 in | 420.0 | 15.56 | 17.11 | 700 | 934 |
Bag counts assume about 0.60 cubic feet per 80 lb bag and 0.45 per 60 lb bag, rounded up.
How thick to pour it
Four inches is the usual thickness for patios, walks and shed floors. Slabs that carry cars or a heavy hot tub are often poured at 5 to 6 inches, and edges are sometimes thickened where loads concentrate.

Truck or bags?
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
Uneven ground is the main reason pours run short. Every half inch of extra depth across the slab 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.
Keeping cracks under control
Cut or tool control joints so the slab cracks where you want it to. A common rule is spacing them, in feet, at no more than two to three times the slab thickness in inches, so about 10 feet apart for a 4-inch slab, and about a quarter of the slab depth deep.
