Gravel is essential for driveways, pathways, drainage systems, and landscaping. This calculator determines how much gravel you need based on area and desired depth, converting to both cubic yards and tons for easy ordering.
Gravel depth depends on use: driveways need 4-6 inches, pathways require 2-3 inches, and drainage applications may need 6-12 inches. Crushed stone compacts better than rounded pea gravel, making it ideal for driveways and parking areas.
Gravel is typically sold by the ton or cubic yard. The conversion factor varies by stone type - crushed stone averages 1.4 tons per cubic yard, while lighter stones like lava rock weigh less. Always verify the weight with your supplier.
For best results, prepare the base by removing grass and topsoil, then compact the subgrade. Consider installing landscape fabric to prevent weeds. Edge the area with borders to contain the gravel and create a finished appearance.
Quick Tips
