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.
