Summary
Calculate the volume and weight of limestone needed to cover an area given length, width, and depth.
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.
Use cases
Estimating crushed limestone for a driveway or road base.
Calculating agricultural limestone needed for soil amendment.
Planning limestone aggregate fill for drainage trenches or foundations.
Ordering limestone screenings for a compacted base layer.
Budgeting limestone for a garden path or decorative landscape bed.
Computing tonnage for a commercial construction or civil engineering project.
Frequently Asked Questions
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).
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.
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.
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.
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).
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.
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.
