Gravel calculator: cubic yards

Cubic yards is the unit most bulk gravel suppliers use when they talk about volume rather than weight, which makes it a natural number to lead with if you are planning to call around for quotes before committing to a specific supplier. This page starts from that unit and then converts into tons and bags from the same footprint, which is the reverse order from the gravel calculator for tons, which leads with weight instead. Which page to start from mostly comes down to how your supplier prices the material, since some quote strictly by weight and others strictly by volume, and a few will do either on request. There is no real advantage to one unit over the other mathematically, so it is mostly a matter of matching whichever page's output lines up with how your particular supplier talks about price.

The relationship between a cubic yard and a cubic foot is fixed regardless of what material fills it, twenty seven cubic feet to the yard, which is useful to keep in mind if you are sanity checking a result by hand rather than trusting the calculator blindly. Converting a cubic yard figure into tons, on the other hand, depends entirely on the density of the specific material selected, which is why that second conversion needs the material picker above rather than a single fixed ratio. The guide on tons per cubic yard goes through that density dependent conversion in more depth if the relationship between the two units is the part you actually want explained. Keeping the two figures side by side rather than discarding one once you have the other is useful if you end up dealing with more than one supplier, since it lets you translate between a yard based quote and a ton based one without having to recompute from your original measurements each time.

Suppliers quoting in cubic yards are often doing so because bulk gravel is scooped by the loader bucket and delivered by the truckload, both of which are more naturally measured in volume than weighed precisely until the truck crosses a scale. That is also why a cubic yard figure from this page is a good number to have in hand before calling for a quote even if the supplier ultimately bills you by the ton, since it lets you ask whether their stated price per yard and price per ton line up with each other for the specific material you want, rather than discovering a mismatch after delivery. A mismatch between the two is not always an error either, since some suppliers use a slightly different density assumption for the same named material, which is worth asking about directly rather than assuming the lower of two quotes is automatically the better deal.

A pickup truck bed is a common point of comparison people reach for when thinking about cubic yards, since hauling material yourself rather than paying for delivery is often the cheaper option for a small job if you already own a suitable vehicle. Truck bed capacity varies enough by make and model that it is worth checking your specific vehicle's rated payload rather than assuming a full bed is always within a safe hauling weight, since gravel is dense enough that a full bed of stone can exceed what some trucks are rated to carry even though it looks like it would fit easily by volume. When in doubt, asking the supplier to fill the bed to a specific weight rather than a specific visual level is the safer way to load a pickup truck for a self haul trip.

Once the cubic yard figure above is settled, the gravel calculator for square feet is useful if you need to work backward to confirm the footprint a given order will cover, and the how much gravel do I need calculator is the broader starting point if cubic yards turns out not to be the unit your supplier actually wants. For checking the figure against material already on hand rather than a planned order, the gravel coverage calculator runs the same volume to area relationship in reverse. Whichever page you end up using, keeping the original length, width and depth measurements written down somewhere makes it easy to rerun any of these calculators later if the project changes before the gravel actually arrives.
