2 Inch River Rock Calculator
Calculate Material Needed for Your Landscaping Project
When planning a landscaping project involving 2-inch river rock, one of the biggest challenges is accurately estimating the amount of material required. Ordering too little can cause delays and extra trips, while ordering too much increases costs unnecessarily.
Our 2 Inch River Rock Calculator helps you determine how much river rock you need based on your project’s dimensions, depth, and shape. It also provides cost estimates based on your pricing inputs, including delivery fees.
Whether you’re covering a garden bed, creating a pathway, or designing a driveway, this tool simplifies your planning and budgeting process by providing accurate material volume and cost estimates.
How to Use the 2 Inch River Rock Calculator
Step 1: Enter Project Dimensions
- Length (Feet): The longest dimension of your project area.
- Width (Feet): The width of your project area.
Step 2: Enter Depth
Input the depth in inches. A depth between 2 to 4 inches is generally recommended — thinner coverage may not provide sufficient ground coverage, and thicker layers can increase cost and weight.
Step 3: Choose Project Shape
Select the shape of your project:
- Rectangle/Square
- Circle (use diameter as length)
- Triangle
The calculator adjusts area calculations accordingly.
Step 4 (Optional): Input Pricing Details
- Price Per Ton and/or Price Per Cubic Yard of river rock.
- Delivery Fee if applicable.
Step 5: Click Calculate
You will get the following outputs:
- Project area in square feet
- Volume needed in cubic feet and cubic yards
- Tons of river rock required (based on density)
- Number of 0.5 cubic foot bags equivalent
- Estimated costs based on tonnage and cubic yards plus delivery fees
- Helpful notes on recommended usage and considerations
Example Calculation
Suppose you want to cover a rectangular garden bed 20 feet long and 5 feet wide, with a depth of 3 inches. You know the price per ton is $50, price per cubic yard is $65, and delivery fee is $100.
- Area = 20 × 5 = 100 sq ft
- Depth in feet = 3 inches ÷ 12 = 0.25 ft
- Volume = 100 × 0.25 = 25 cubic feet
- Cubic yards = 25 ÷ 27 ≈ 0.93 cu yd
- Tons needed = 0.93 × 1.4 ≈ 1.30 tons
- Bags (0.5 cu ft each) = 25 ÷ 0.5 = 50 bags
Cost:
- By ton = 1.30 × $50 = $65.00
- By yard = 0.93 × $65 = $60.45
- Add delivery fee $100
Total cost by ton + delivery = $165
Total cost by yard + delivery = $160.45

Frequently Asked Questions (FAQs)
- What size river rock does this calculator use?
It’s designed for 2-inch river rock, which is a common size for landscaping and pathways. - Why do I need to specify the project shape?
Because area calculations differ between rectangles, circles, and triangles. - What is the recommended depth for river rock?
Typically 2 to 4 inches. Less than 2 inches may not cover well; more than 4 inches could be excessive. - How is the weight calculated?
The calculator assumes 1.4 tons per cubic yard of 2-inch river rock. - What if my project shape is irregular?
Approximate your area using one of the available shapes or break the area into sections. - Can I use this for other sizes of river rock?
The calculator is optimized for 2-inch rock; other sizes have different densities and may require adjustments. - What if I want to use bags instead of bulk rock?
The calculator converts volume into the number of 0.5 cubic foot bags needed. - Does this calculator include delivery fees?
Delivery fees can be input separately and added to total cost estimates. - How much extra material should I order?
It’s advisable to order 5-10% more to account for settling or uneven ground. - Can this calculator help with driveway projects?
Yes, for driveways a depth of 3-4 inches is recommended.
Conclusion
Planning a landscaping project with 2-inch river rock is easier with precise estimates of material needed and costs. This 2 Inch River Rock Calculator takes the guesswork out of your project planning, saving you time and money.
By entering your project dimensions, depth, shape, and pricing details, you can quickly get a clear picture of how much river rock you need and the associated costs, helping your landscaping project run smoothly from start to finish.
