Planning a landscaping project? Great! But figuring out how much river rock you need can be a pain. Don’t worry. Our River Rock Stone Calculator is here to make things easy.

You’ll save time, money, and energy. Just enter your numbers, and boom your rock estimate is ready. Whether you’re filling a garden bed or lining a walkway, this tool’s got your back.

What’s the Calculator For?

This tool helps you figure out how much river rock you need. It works for all rock sizes like 2 inch and 3/4 inch river stones. You’ll get results in cubic yards or square feet. No math headaches.

How to Use It (It’s Super Simple)

You don’t need to be a math whiz. Here’s what to do:

1. Measure Your Space

Use a tape measure. Find the length and width in feet.

Let’s say your garden bed is 10 feet long and 6 feet wide:

10 × 6 = 60 square feet

2. Pick a Rock Depth

Most people go with 2 inches deep. That’s about 0.167 feet.

Want a thicker layer? No problem. Just change the depth.

3. Do the Math (or Let Us Do It)

Here’s the formula:

Square feet × Depth (in feet) = Cubic feet

Cubic feet ÷ 27 = Cubic yards

Example:

60 sq ft × 0.167 = 10.02 cubic feet

10.02 ÷ 27 = 0.37 cubic yards

So you’ll need 0.37 cubic yards of river rock.

How Much Rock Covers What?

Here’s a rough idea to help you plan:

• 1 ton covers about 100 sq ft at 2 inches deep
• 50 lbs covers about 0.5 sq ft
• 1 cubic yard covers 120–150 sq ft, depending on rock size

Smaller rocks (like 3/4 inch) fill gaps better. Bigger ones (like 2 inch) need more space.

Why Use This Calculator?

Because guessing is risky. You might buy too much and waste money. Or buy too little and run short.

This calculator helps you:

• Get the right amount
• Save time
• Stay on budget

It’s quick, easy, and totally free.

Real-Life Example

Let’s say you’re building a stone path in your backyard. It’s 12 feet long and 4 feet wide. You want 2-inch river rocks.

Here’s the math:

12 × 4 = 48 sq ft

48 × 0.167 = 8.016 cubic feet

8.016 ÷ 27 = ~0.3 cubic yards

So you’ll need about 0.3 yards of river rock. Easy, right?

Final Thoughts

Don’t stress over rock math. Let our River Rock Calculator do the hard part. It’s perfect for anyone whether you’re a DIY lover or a pro landscaper.

Start with your space size. Pick your depth. Get your results. That’s it.
