Estimate how much gravel you need for driveways, paths, landscaping, pads, and ground cover.
Multiply area by depth to estimate volume. Convert depth from inches to feet by dividing by 12.
Formula: area × depth in feet = cubic feet
Divide cubic feet by 27 to convert to cubic yards.
Add 5% to 10% extra gravel for compaction, uneven ground, spreading differences, and waste.
Multiply area in square feet by depth in feet to get cubic feet. Divide by 27 to get cubic yards.
Common depths range from 2 to 4 inches for landscaping and can be deeper for driveways or base layers.
Yes. Adding 5 to 10 percent extra is useful for compaction, waste, and uneven areas.
