1 Cubic Yard = 202 Gallons
When you call a ready-mix concrete supplier in the United States, they'll quote you a price per yard—meaning one cubic yard. This is the universal measurement for concrete orders, and understanding it is essential before your truck arrives. One cubic yard equals 202 gallons, or 0.76 cubic meters for metric reference. Knowing this conversion helps you visualize how much material you're actually ordering.
What Exactly Is a Cubic Yard?
A cubic yard is simply 3 feet × 3 feet × 3 feet = 27 cubic feet of volume. It's not complicated mathematically, but visualizing it helps. Imagine a washing machine and dryer stacked on top of each other—that's roughly the physical size. A single cubic yard of concrete weighs approximately 4,000 pounds, which is why delivery trucks are so heavy and why you need a solid foundation to receive it.
Why This Matters for Your Project
Thickness directly determines how many yards you'll need. The same concrete, poured thinner, stretches further across your space. For example:
- 4 inches thick: 1 yard covers 81 square feet
- 5 inches thick: 1 yard covers 65 square feet
- 6 inches thick: 1 yard covers 54 square feet
A typical residential driveway (10 feet × 20 feet × 4 inches) requires about 2.5 cubic yards. If you increase thickness to 5 inches for better durability, you'll need 3.1 yards instead. That single-inch difference costs you real money—usually $150–$250 per yard depending on your region.
Calculating Your Order Accurately
The most common mistake homeowners make is underestimating thickness requirements. A 4-inch slab is minimum for driveways in freeze-thaw climates; 5–6 inches is better for load-bearing surfaces. Patios and light-traffic areas can work at 3–4 inches.
Use our concrete slab calculator to enter your exact dimensions and desired thickness. It will automatically calculate the cubic yards you need, eliminating guesswork. Ordering too little means a return trip for concrete (expensive and logistically difficult). Ordering too much wastes money and material.
Sourcing and Pricing Tips
Ready-mix suppliers charge by the cubic yard, with typical ranges from $130–$200 per yard depending on your location, concrete strength (measured in PSI), and air-void specifications. Some suppliers offer discounts for larger orders (5+ yards), while others charge delivery fees for orders under 3 yards.
Always confirm the concrete strength (3,000 PSI is standard for residential driveways) and ask whether the price includes delivery or if it's FOB plant. A truck typically carries 9–10 cubic yards maximum, so orders beyond that require multiple deliveries.
Don't Guess on Volume
Concrete is one area where precision pays off. A miscalculation of just half a cubic yard can disrupt your pour schedule or force you into an expensive emergency situation. Before placing your order, triple-check your measurements and thickness specification. The small effort upfront saves headaches—and money—on job day.
