Work out how much landscaping or crushed stone you need and what it will cost. Choose a rectangular or circular area, enter the size and the stone depth (presets for 2″, 3″ and 4″), then set the stone density and add a waste allowance, price per ton and optional delivery fee. You'll get the cubic yards, tons, bags and total cost, plus a full breakdown, by-depth and by-stone-type comparison tables, a chart, and a downloadable PDF report.
Estimate only. Volume = area × depth ÷ 27 cubic yards (circle area = π × (diameter ÷ 2)²); weight = cubic yards × density; bags = volume ÷ 0.5 cu ft. Stone density varies widely with type and moisture (crushed stone and river rock ≈ 1.4, pea gravel ≈ 1.35, lava rock ≈ 0.55 tons per cu yd), so confirm with your supplier — who sells bulk by the ton and small amounts by the bag. For a weed-free bed, lay landscape fabric and edging first, and order a little extra.

We work out the surface area, multiply by the depth for the volume, add waste, then convert to cubic yards, tons, bags and cost.
