Landscape stone adds beauty, functionality, and low-maintenance appeal to outdoor spaces. From decorative river rock to functional pea gravel, choosing and calculating the right amount of stone is crucial for project success. Our Landscape Stone Calculator helps you determine exact quantities, including volume, weight, and cost estimates for eight popular stone types.
Calculating stone needs involves volume and weight conversions. The formulas are:
Volume (cubic feet) = Length × Width × Depth (in feet)
Cubic Yards = Volume ÷ 27
Weight (tons) = Cubic Yards × Stone Density (typically 1.3-1.5 tons/yd³)
Bags = Total Weight (lbs) ÷ Bag Weight
Choose stone based on function, aesthetics, and budget:
