The Limestone Calculator estimates how much material you need for paving, drainage, landscaping, or construction projects where limestone is spread over an area. Enter your project's length, width, and depth, then select your limestone type (loose, crushed, or low/medium/high-density) and a wastage factor to get the volume in cubic yards plus weight in tons and pounds.

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.
