How many yards are in a ton of gravel?

0.67cubic yards

in one US ton of gravel

One US ton of ¼–2 inch gravel is about 0.67 cubic yards, because a cubic yard weighs roughly 1.5 tons (2,970 lb). Lighter stone gives you slightly more volume per ton: river rock is nearer 0.8 cubic yards.

cubic yards = 2,000 ÷ pounds per cubic yard

  • One US ton of ¼–2 in gravel is about 0.67 cubic yards
  • One cubic yard of that gravel weighs about 1.5 tons (2,970 lb)
  • One ton covers about 55 sq ft at 4 inches deep
  • One ton covers about 109 sq ft at 2 inches deep
  • River rock is lighter: nearer 0.8 cubic yards per ton

Order by weight, plan by volume

Suppliers sell gravel by the ton but you measure the driveway in square feet and inches. Work out the volume first, convert with the weight for your stone, then order the tons.

Stone size changes the weight

Crusher run with fines packs tighter and weighs the most per yard; clean ¼–2 inch gravel sits in the middle; 2–6 inch river rock has larger voids and weighs least. That spread is why a ton can be 0.6 to 0.8 cubic yards.
