Gravel Calculator Guide
Estimate gravel volume in cubic yards from area, depth, compaction, and waste.
Measure area
Measure length and width in feet. Split curves or irregular areas into approximate rectangles.
Choose depth
Depth depends on use. Walkways, base layers, and driveways need different depths.
Convert to cubic yards
Area x depth gives cubic feet. Divide by 27 for cubic yards.
Allow compaction
Gravel settles and compacts, so add extra when the layer will be compacted.
FAQ
How deep should gravel be?
Light paths may use a few inches. Driveway bases usually need more depth.
Does gravel compact?
Yes. Compaction reduces final height and can require extra material.
Should I use fabric under gravel?
Landscape fabric can help separate soil from gravel in some projects.
