How Much Landscape Rock Do You Need? Calculating Tonnage for Your Project

Decorative rock is sold by the ton, and coverage depends on rock size and density. For a 2-inch depth over 1,000 square feet, you'll need roughly 6–7 tons of ¾-inch rock, but this varies. Use an online calculator (e.g., earthproducts.net) that factors in rock type, depth, and area. Always order 5–10% extra for compaction and irregular edges.
