Gravel Calculators
The right answer depends on the right material. These tools are pre-set for a specific gravel type — its density, its typical depths, and the questions people actually ask about it — so you don't have to know the numbers to get a useful estimate.
Pea Gravel Calculator
Yards, tons, bags, and cost for pea gravel — walkways, playgrounds, and landscape beds, with bag-versus-bulk guidance.
Crushed Gravel Calculator
Quantities for crushed stone, crush and run, and road base, including what common grading codes like #57 actually mean.
Gravel Weight Calculator
Convert gravel volume to weight — and weight back to volume — with a density reference table.
Not sure which material you need?
The general gravel calculator on the homepage handles every material in one tool: pick a shape, enter your dimensions and depth, and choose the material — including common grading codes like #57 and #67 — to get cubic yards, tons, bags, and an estimated cost.
If you think in a specific unit, the converters reframe the same math around cubic yards or tons — the units suppliers quote by. And for a full price tag, the cost tools apply your supplier's rate to your quantities.
If you're planning a specific project rather than shopping by material, the application calculators (driveways, paver bases, French drains, and more) add depth and material recommendations per use case — they're coming to the applications section shortly.
