Crushed Stone Calculator
Pick the stone, type the area you are covering and how deep it goes. The result comes back in the two units crushed stone is sold in — cubic yards and tons.

Both figures are for #57 crushed stone loose, the state it is in when it is delivered and spread.
The formula, written out
(20 ft × 10 ft × 4 in ÷ 12) × (1 + 10% waste) ÷ 27 = 2.72 cubic yards
2.7160 cubic yards × 2500 lb per cubic yard (loose) ÷ 2000 = 3.4 tons
The formula above is the one that produced the numbers: the page asks for both in the same call, so the two cannot drift apart.
A driveway 20 ft by 10 ft at 4 inches deep is 66.67 cubic feet of stone. Adding the 10% waste factor makes 73.33 cubic feet, which is 73.33 ÷ 27 = 2.72 cubic yards. At 2,500 pounds per cubic yard that is about 6,790 pounds, or 3.4 tons.

Your supplier has the last word. Aggregates vary by quarry and soil varies by the week it was dug, so the range above is what to expect and not a promise about the load you are buying. The weight on their ticket is the one you pay for.
The two weigh about the same and do completely different jobs. Picking between them above changes the tonnage barely at all; what it changes is what you ask the yard for. Ordering #57 where the job needed crusher run gives you a surface that never locks together, and no calculator catches that.
What is the difference between #57 stone and crusher run?
Both are the same crushed rock; what differs is what was screened out. #57 is washed and open-graded, so the stones are all about three quarters of an inch and water runs straight through — that is what makes it a drainage and driveway-surface stone. Crusher run keeps the dust and fines, so it locks together under a plate compactor and makes a base that stays put. If you are building up a driveway you usually want both: crusher run underneath, #57 on top.
How much does a cubic yard of crushed stone weigh?
About 2,500 pounds for either one, loose, which works out near 1.25 tons. The two products are much closer in weight than they are in behaviour — the spread inside each range comes from the quarry the rock came out of, not from which of the two you ordered.
How deep should crushed stone go?
For a walking path 2 to 3 inches is plenty. A driveway that carries cars usually wants 4 inches of crusher run compacted as a base with 2 to 3 inches of #57 on top, and heavier ground or soft soil wants more. This page works out how much a depth needs; it does not tell you what depth to build, and it is not structural advice.
Should I order by the ton or by the cubic yard?
Whichever your yard sells in — both are given above for that reason. Yards in some regions quote crushed stone by the ton and others by the cubic yard, and the conversion between the two runs through the weight, which varies by quarry. If you are close to a full extra ton either way, ring them and ask what their own yard weighs.
