Stone Calculator
One ton of landscape stone covers about 80 to 100 square feet at 2 inches deep; a cubic yard weighs roughly 1.4 tons.
Stone yards price by the ton, but you measure the job by volume. Enter your area and depth to get cubic yards first, then the tonnage to quote against, at a typical crushed-stone density.

Stone questions people actually ask
- How many tons of stone do I need?
- Work out cubic yards first (area x depth / 27), then multiply by 1.4 — crushed stone averages about 2,800 pounds per cubic yard.
- How much area does a ton of stone cover?
- Roughly 100 sq ft at 2 inches, 70 sq ft at 3 inches and 50 sq ft at 4 inches for typical 3/4-inch crushed stone.
- How deep should landscape stone be?
- Two inches for decorative beds over fabric, three inches for paths, and four or more inches for driveways where vehicles will run.

How this number is calculated
2,800 lb/yd³ is a common figure for dry 3/4-inch crushed limestone. Granite and trap rock run heavier; lava rock far lighter. Volume is area × depth, converted to cubic yards by dividing cubic feet by 27. See all our assumptions.
