You need _____ Tons of River Rock
How To Measure
Measure the length and width of each landscape bed in feet. For irregular or curved beds, break them into smaller rectangles and circles and add each one — the calculator sums multiple areas for you. Then set your depth: 3 inches is our standard for weed-blocking ground cover. One ton of river rock covers roughly 80 square feet at 3 inches deep, so a typical 100-square-foot bed needs about 1.5 tons.
Depth Recommendations
Landscaping beds & borders: 3 inches (blocks sunlight and prevents weeds). ~80 sq ft per ton.
Dry creek beds & drainage: 4–6 inches (for visual depth and water flow). ~55–65 sq ft per ton.

Do I need fabric underneath it?
Absolutely. If you put river rock directly on mud, the heavy stones will slowly sink into the earth until they disappear. You must use a heavy-duty non-woven geotextile fabric to separate the rock from the soil.
Is it hard to clean?
It's actually easier than mulch. Because the rocks are heavy, you can use a leaf blower on full power to blast autumn leaves off the rocks without blowing the rocks away.
