Estimate gravel volume in cubic feet and cubic yards from area dimensions and installation depth.
Gravel volume depends on both surface area and installed depth. The calculator converts the depth to feet, works out cubic feet and then converts to cubic yards.
Cubic yards = area \u00d7 (depth \u00f7 12) \u00f7 27A 20 \u00d7 10 ft area at 3 in deep is about 1.85 cubic yards before contingency.
It depends on the project. Decorative paths may use a shallower layer than driveways or structural base courses.
The conversion depends on gravel type, moisture and density. Use your supplier’s tons-per-cubic-yard figure for the specific material.
Often yes for compacted applications. Supplier guidance is best because compaction varies with material and installation method.
Yes, first calculate the circle area using π × radius², then use that square-foot area with the required depth.
