Estimate gravel needed in cubic feet, yards, meters, and tons for any project.
Volume = area × depth; cubic yards = cubic feet / 27; tons = cubic yards × density (tons per cubic yard).
A 100 sq ft path covered 2 inches deep with gravel at 1.4 tons/yd³ needs about 0.86 tons.
A 2–4 inch layer is typical for paths and driveways; deeper layers resist rutting better.
The volume in cubic yards is multiplied by the gravel density, commonly 1.4–1.7 tons per cubic yard depending on the type.
Yes. Add 5–10% for settling and uneven subgrade.
