About this calculator
Overview
Building a gravel driveway requires calculating the volume of the excavated area and converting that to material weight. Accurate estimates ensure you don't overpay for delivery or run out of material mid-project.

Pro Tips
Order 5-10% more gravel than the minimum to account for base unevenness and future settling.
Use a landscape fabric (geotextile) under the gravel to prevent the stone from sinking into the soil.
Consider a 'crown' in the middle of your driveway for better water drainage.

Fun Facts
"Standard driveway depth is usually 4 to 6 inches, with a base layer of larger stones and a top layer of finer gravel."
"One cubic yard of gravel covers approximately 100 square feet at 3 inches of depth."
"Gravel can settle by up to 20% over time; adding a waste factor helps account for compaction."
