What is the Gravel Calculator?
The Gravel Calculator estimates the volume and weight of gravel needed to cover an area to a specified depth. It accounts for different material densities to give an accurate tonnage estimate.
How to Use
- Measure the length and width of the area in feet.
- Enter the desired gravel depth in inches.
- Select the material type to apply the correct density.
- Click Calculate Gravel to see cubic yards and tons.
Frequently Asked Questions
How many tons of gravel do I need per cubic yard?
Most gravel weighs about 1.4 tons per cubic yard. Pea gravel is lighter at about 1.3 tons, while crushed stone can be closer to 1.5 tons.
How deep should driveway gravel be?
For a driveway base, 4 to 6 inches of gravel is typical. For decorative paths, 2 to 3 inches may be sufficient.
Should I compact the gravel?
Yes, compacting gravel reduces voids and creates a stable surface. Compaction can reduce volume by about 10-15%, so order extra material accordingly.
What is the difference between gravel and crushed stone?
Gravel is naturally rounded from water erosion. Crushed stone is mechanically broken into angular pieces, which lock together better for driveways and construction bases.
