What this estimate includes

This estimate shows decorative rock in cubic yards, tons, and bag equivalents based on bed size, depth, rock type, and bag size.

How it’s calculated

Area = length × width
Volume = area × depth × waste %
Cubic yards = cubic feet ÷ 27
Tons = cubic yards × selected rock density
Bags = cubic feet ÷ bag size, rounded up

Before you order

Decorative rock coverage varies by stone size and how evenly the bed is graded. Confirm rock density and bag coverage with your supplier before ordering.
