Cubic Yard Calculator Guide
The cubic yard is the native currency of bulk material — quarries price in it, dump trucks are sized around it, and every landscape quote you’ll ever receive speaks it. Yet almost nobody has an intuitive feel for how big one actually is. A cubic yard is a cube measuring 3 feet on every side: 3 × 3 × 3 = 27 cubic feet. Dumped on a driveway, it makes a pile about 5 feet across and knee-to-thigh high. Moving it by hand means roughly 14 trips with a typical 2 ft³ wheelbarrow — call it an honest hour of shoveling.
The formula is short: length × width × depth, all in feet, divided by 27. The depth is where projects go wrong, because it’s measured in inches — divide it by 12 before multiplying. A 20 × 15 ft parking pad at 4 inches deep is 20 × 15 × 0.333 = 100 ft³, which is 3.7 cubic yards.
How Far Does One Cubic Yard Go?
| Depth | Coverage per yd³ | Typical use |
|---|---|---|
| 1 in | 324 sq ft | Top-dressing existing gravel |
| 2 in | 162 sq ft | Decorative ground cover |
| 3 in | 108 sq ft | Landscape beds, path surface |
| 4 in | 81 sq ft | Driveway base lift, slab base |
| 6 in | 54 sq ft | Heavy-duty base, French drain |
| 12 in | 27 sq ft | Deep fill, retaining-wall backfill |
The shortcut hiding in that table: divide 324 by your depth in inches and you get the square footage a single yard covers at that depth. It works for any material, because coverage is pure geometry — weight is where materials diverge. One yard weighs about 3,000 lb as crushed stone, 2,800 lb as gravel, 2,200 lb as topsoil, and just 800 lb as mulch.
Ordering and Hauling by the Yard
- Your pickup fits a yard by volume, not by weight. A full-size bed physically holds a yard of stone, but at 3,000 lb it’s double most half-ton payload ratings. Haul stone a half yard at a time, or let the quarry’s truck take the strain.
- Delivery minimums favor consolidation. Many yards charge the same delivery fee for 1 yard as for 10. If a second project is on the horizon, ordering together can effectively make the extra material half price.
- A tandem truck carries 9–10 yards of stone. That’s the 13–15 ton legal payload; larger orders arrive as multiple trips, so plan the dump spot for repeat access.
- Round up to the half yard. Loader operators work in half-bucket increments anyway, and being a wheelbarrow short at the end costs a second trip.
Once you know your yards, converting to a purchase weight takes one more step — the cubic yards to tons calculator applies the right density for any material. And if your starting point is an area on a plan rather than a measured hole, the square feet to tons calculator goes straight from footprint to order size.
