    Questions

    About the yard calculator

    How are cubic yards worked out?

    Multiply length, width and thickness in feet to get cubic feet, then divide by twenty-seven. The tool does it for you and adds your waste allowance.

    Why add extra?

    Ground is never perfectly flat and forms bow a little, so many people order a bit more than the exact number.

    How many bags make a yard?

    It depends on the bag size. The tool shows a count for common bag sizes so you can compare with a truck.
