Enter your project's Length, Width, and Depth, then choose your Limestone Type and Wastage Factor — the Limestone Calculator gives you the Volume Needed in cubic feet, plus the Weight in pounds so you know exactly how much material to order.

Limestone is a sedimentary rock composed mainly of calcium carbonate that forms from decomposed marine organisms. It's typically white but can appear grayish to black with organic matter, or yellowish/reddish with iron oxide traces.
Limestone is used for driveways, walkways, landscaping, drainage projects, and as a base material. It can be cut into pavers or crushed for aggregate in concrete and cement production.
Calculate the volume by multiplying length × width × depth, then add a wastage factor (typically 10-15%). Multiply by limestone density to get weight in tons or pounds.
A cubic yard of limestone typically weighs between 2,500-4,000 pounds (1.25-2 tons), depending on the density and type of limestone. Crushed limestone averages about 3,200 pounds per cubic yard.
One ton of crushed limestone covers approximately 80-120 square feet at 2 inches deep, or 40-60 square feet at 4 inches deep, depending on the stone size and compaction.
A wastage factor accounts for material loss during transport, spillage, compaction, and irregular surfaces. Adding 10-15% ensures you have enough material to complete your project.
Low-density limestone is lighter and more porous, while high-density limestone is heavier and more compact. Crushed limestone has consistent sizing, while loose limestone has varied particle sizes.
