How much gravel do I need for a driveway?

Measure the length and the width, decide the depth of the surface layer, and the page does the rest. The 30 by 10 foot drive it opens with at 4 inches is 3.70 cubic yards, 2.83 cubic metres and 4.25 tonnes at 1.5 tonnes per cubic metre. A 50 by 12 foot drive at the same depth is 7.41 cubic yards and 8.50 tonnes, and a long 100 by 10 foot run is 12.35 cubic yards and 14.16 tonnes. A 20 by 20 foot parking pad is 4.94 cubic yards and 5.66 tonnes.

How deep should the gravel on a driveway be?

Enter the depth specified for the layer you are measuring. The opening 4-inch value and the separate 10 cm metric example are editable arithmetic examples, not recommended depths. This page does not specify excavation, base layers, structural suitability or drainage.

How many tons of gravel for a 30 by 10 foot driveway?

At 4 inches deep it is 100 cubic feet, which is 3.70 cubic yards and 2.83 cubic metres. At 1.5 tonnes per cubic metre that is 4.25 tonnes, or 4.68 US short tons. Change the material to crushed stone at 1.6 and it reads 4.53 tonnes; pea gravel at 1.7 gives 4.81. The volume never moves, only the weight, which is the whole reason this page keeps the two figures apart and shows the density it used.

Should I order a driveway by the ton or by the yard?

The page displays volume and mass at your supplied density, so you can read either quantity. It does not choose how to order or convert a supplier quote into a procurement recommendation. The optional price field multiplies your supplied rate per metric tonne only; delivery, labor and other charges are excluded.

Should I add extra for settling?

There is no hidden settling or compaction allowance. The calculator uses the supplied area, depth and density for one layer. It cannot choose a margin or estimate compaction from those numbers. Enter the layer dimensions specified for your calculation.

Driveway Gravel Calculator

Work out how much gravel a driveway needs, by volume and by weight. The editable example opens at 30 feet by 10 feet and 4 inches deep: 3.70 cubic yards and 4.25 tonnes at the supplied 1.5 t/m³ density. Its separate metric example is 9 metres by 3 at 10 cm: 3.53 cubic yards and 4.05 tonnes. Enter your own dimensions or known area, depth and density. The example does not prescribe a driveway depth, construction layers, compaction, drainage or material suitability.

Depth and density are supplied inputs. The material buttons set editable examples; they do not identify your material, certify a grade or choose a layer depth.
Rectangle and supplied-area arithmetic and unit factors are exact. Circle volume is π times the stated coefficient; decimal displays use a 100-place bound for π and are approximate.
Mass follows the supplied density. Bags round up from the full mass before display rounding; a range means the π bound straddles a bag boundary. Larger abbreviated quantities have complete values below.
This is a single-layer quantity estimate. No compaction, excavation, base design, drainage, installation, suitability, delivery or regional price is inferred.
