How to Calculate Gravel & Crushed Stone

Gravel is typically sold and delivered by the ton rather than by volume. To convert cubic yards to tons:

Tons = Cubic Yards × Material Density (approx 1.35 to 1.45 tons/yd³)

When gravel is spread and driven on or rolled with a plate compactor, it compresses by 10% to 15%. Always factor in compaction to prevent running short during installation.

Frequently Asked Questions

A proper gravel driveway consists of 3 layers: 4 inches of large #3 or #4 crushed base rock, 4 inches of #57 stone for stability, and 2 inches of finer pea gravel or driveway gravel on top—totaling 8 to 10 inches.

A 10-ton dump truck delivery usually costs between $350 and $600 including delivery fees. Buying that same volume in 50 lb bags from a home center would cost over $2,000!
