Enter your area and depth to see how much gravel to order by the yard, ton or bag. Most paths and beds need 2 to 3 inches, and driveways need more.

How it works

Length × width × depth in feet gives cubic feet. Divide by 27 for cubic yards, then multiply by about 1.4 tons per yard for typical gravel.

Before you order

  • Ask whether your supplier sells by the ton or the yard before you compare prices.
  • Lay landscape fabric first on decorative beds so stone does not sink into soil.
  • Stone with sharp edges locks together. Round stone keeps moving underfoot.
