How Much Stone Do You Need?
To find out how much stone you need, you’ll first need to calculate the volume needed in cubic yards. You can do this using the classic volume formula and a few simple steps.
First, measure the length, width, and depth of the space in feet, then multiply them together to calculate the volume in cubic feet. Then, divide by 27 to get cubic yards. You can use a length converter to convert to feed if needed.
volume = length × width × depth
cubic yards = cubic feet ÷ 27
Next, calculate the amount of stone you need in tons by multiplying the volume by the density of the stone material. Most crushed stone or gravel weighs 1.4 to 1.7 tons per cubic yard, while larger stone usually weighs 1.5 to 1.7 tons per cubic yard.
amount of stone = cubic yards × 1.7
Thus, the amount of stone needed is equal to the volume in cubic yards times 1.7. You can also use our gravel calculator to find out how much gravel you need.
