Gravel Calculator

About 1.4 US tons for typical 3/4 inch crushed gravel, so a yard and a half of gravel is around 2 tons. Suppliers vary, and the figure shifts with stone type and moisture — ask for the density they are quoting against.

Roughly 75 to 80 square feet at 3 inches deep, or about 100 square feet at 2 inches. That assumes a density near 2,800 lb per cubic yard.

Three-eighths to half-inch angular crushed stone or crusher run compacts into a firm, comfortable surface. Avoid large rounded river rock — it rolls underfoot and is genuinely unpleasant to walk on.

For decorative gravel over soil, yes — it slows weeds and stops the stone sinking. Under a compacted driveway base, skip the fabric and use a proper geotextile separation layer instead, which is engineered for the load.

Measure the length and width in feet at the widest points and multiply them. For an irregular bed, break it into rectangles, circles and triangles, calculate each one separately and add the results together. Rounding up slightly is safer than rounding down.

Bulk is almost always cheaper per cubic yard once you need more than about 1 cubic yard — roughly 54 bags. Bags win when you need a small amount, have nowhere to dump a pile, or want to spread the job over several weekends.

A half-ton pickup can usually carry about 1 cubic yard of light material like mulch, but only around half a cubic yard of wet soil or gravel because of the weight. Check the weight figure above against your vehicle's payload rating before you load up.
