    They all share one engine

    Every calculator here uses the same volume formula and the same density table — the specialised ones simply pre-set the depths, layers, and materials that match the job, so you cannot accidentally build a driveway at patio depth. The methodology is documented on how it works.

    Frequently asked questions

    Which calculator should I start with?

    The main gravel calculator handles any rectangular, circular, or triangular area at any depth. Start there unless your job is a driveway, which has its own multi-layer calculator.

    Why are there separate calculators for the same material?

    Because the depth, layering, and pricing differ. A pea gravel patio and a pea gravel playground use the same stone at very different depths, and getting that wrong is the expensive part.
