To help you plan your project effectively, rockscapes.net provides detailed information on coverage, cost, and design ideas for using river rock in your landscape, ensuring you achieve the perfect look while staying within budget. Dive deeper into the world of landscape rock with us, exploring cost-effective strategies, design inspirations, and the practicality of different rock types like pea gravel and crushed stone.
1. Understanding River Rock Coverage
Determining the right amount of river rock for your landscaping project is crucial. River rock is available in various sizes, typically ranging from 3/8 inch to 5 inches or larger, and the size you choose will impact the coverage area. Let’s break down the coverage you can expect from different quantities of river rock:
1.1. Coverage Based on Quantity
To get a clear picture of how much river rock you need, here’s a detailed breakdown of coverage based on different units of measurement.
| Unit of River Rock | Coverage Area (at 2″ Depth) | Coverage Area (at 3″ Depth) | Coverage Area (at 4″ Depth) |
|---|---|---|---|
| 1 Ton | 115 – 135 Square Feet | 80 – 90 Square Feet | 55 – 65 Square Feet |
| 1 Cubic Yard | 160 – 170 Square Feet | 100 – 110 Square Feet | 75 – 85 Square Feet |
| 40 lb Bag | 2.5 – 3.0 Square Feet | 1.5 – 2.0 Square Feet | 1.0 – 1.5 Square Feet |
These figures are based on river rocks that are typically 1 inch to 4 inches in size, which is the most common range for landscaping applications.
1.2. Factors Affecting Coverage
Several factors can influence how much area a bag of river rock will cover.
- Rock Size: Smaller rocks will generally cover a larger area because they can pack together more tightly, whereas larger rocks will leave more gaps.
- Depth: The depth at which you spread the rocks significantly impacts coverage. A 2-inch layer will cover more area than a 4-inch layer.
- Shape: River rocks come in various shapes, from rounded to more angular. Rounded rocks tend to provide more consistent coverage.
- Compaction: After spreading, the rocks may settle, reducing the overall coverage area slightly.
1.3. Estimating River Rock for Common Projects
Let’s consider how these numbers apply to common landscaping projects.

- Convert Depth to Feet: Divide the depth in inches by 12 to convert it to feet.
- Calculate Cubic Feet: Multiply the square footage of the area by the depth in feet.
- Convert to Cubic Yards: Divide the cubic feet by 27 to convert to cubic yards.
For example, if you have a 10’ x 10’ area (100 square feet) and you want a 3-inch depth:
- 3 inches / 12 = 0.25 feet
- 100 square feet x 0.25 feet = 25 cubic feet
- 25 cubic feet / 27 = 0.93 cubic yards
Therefore, you would need approximately 0.93 cubic yards of river rock.

2.1. Price per Ton
River rock costs $45 to $130 per ton on average, depending on the type, location, and size. One ton of river rock typically covers 55 to 135 square feet at a depth of 2 to 4 inches. The price can vary based on local availability, transportation costs, and the specific type of river rock.
2.2. Price per Cubic Yard
On average, river rock costs $50 to $160 per cubic yard. A cubic yard of river rock covers 75 to 170 square feet in a layer of 2 to 4 inches. This measurement is particularly useful for larger projects where buying in bulk is more economical.
2.3. Price per Bag
For smaller projects, river rock is often sold in bags. The price per bag generally ranges from $15 to $35, depending on the size and type of rock. These bags typically weigh between 20 and 50 pounds.
2.4. Additional Costs
