What is the density of crushed limestone?

Crushed limestone has a bulk density of approximately 2,611 kg/m³ (163 lb/ft³). This is for dense crushed stone. Limestone aggregate (looser, air-void-filled) typically runs around 1,602 kg/m³ (100 lb/ft³).

How is limestone volume calculated?

For rectangular areas: Volume = Length × Width × Depth. For circular areas: Volume = π × (Diameter ÷ 2)² × Depth. All dimensions must be in the same unit before multiplying.

How is limestone weight calculated?

Weight = Volume × Bulk Density. The bulk density varies by limestone type — crushed limestone is denser than loose aggregate. This calculator uses industry-standard averages for each type.

Why add a waste factor?

Limestone settles and compacts after installation, and some material is always lost during spreading. Adding 5–10% to your calculated quantity ensures you will not run short before the job is finished.

What is the difference between crushed limestone and limestone aggregate?

Crushed limestone is processed into angular particles with little air space, giving it a higher bulk density (~2,611 kg/m³). Limestone aggregate refers to a graded, looser mix with more void space and a lower bulk density (~1,602 kg/m³).

How many tons of limestone do I need?

Divide total weight in pounds by 2,000 for short tons, or divide kilograms by 1,000 for metric tonnes. This calculator displays both automatically once you click Calculate.

How much limestone do I need for a driveway?

A 10x20 ft driveway at 4 inches deep is 66.7 cu ft (2.47 cu yd) of crushed limestone, or about 5.4 short tons at 163 lb/ft³. For #57 or #610 base stone, plan on 4-inch depth for a base layer and 2 inches for a top dressing.

Summary

A free online limestone calculator that estimates the volume (cubic yards, cubic feet, cubic meters) and weight (short tons, pounds, kilograms) of limestone required for your project. Enter your area dimensions and the desired depth, select a limestone type to apply its bulk density, and add a waste factor to ensure you order enough material. Supports both Imperial and Metric units.

How it works

Choose Imperial (feet/inches) or Metric (meters/centimeters) units.
Select the area shape: rectangular or circular.
Enter the length and width (or diameter for a circular area).
Enter the depth of limestone you need to apply.
Select the limestone type — crushed or aggregate — to use the correct bulk density.
Click Calculate to see total volume and weight with your chosen waste allowance.
