How to calculate gravel for a project
Measure the length and width of the area, then select the compacted depth. A decorative path, driveway, and drainage trench may each need a different section depth or base assembly.
Suppliers sell gravel by cubic yard, ton, bag, or sometimes a truckload. Density changes with rock type and moisture, so use the supplier's conversion when the order becomes final.
Good gravel work starts with the subgrade. Excavation, compaction, slope, edging, and drainage can determine performance more than the top layer alone.
Formulas used
Tons
cubic_yards × material_densityUses an approximate density for delivery planning.
Retail bags
cubic_feet ÷ bag_coverageConverts volume using the bag's stated coverage.
Frequently asked questions
What to know before you order.
How many tons are in a cubic yard of gravel?
Common crushed aggregate is often around 1.4 tons per cubic yard, but rock type and moisture change the actual weight.
What gravel depth should I use?
Depth depends on whether the area is decorative, walked on, driven on, or used for drainage. Follow the system specification rather than one universal number.
Does this include a driveway base?
It estimates the selected aggregate volume. Excavation, subbase layers, geotextile, edging, and grading need separate planning.
