With these inputs:
| Result | Value |
|---|---|
| #57 stone needed | 4.56 tons |
| Volume | 3.26 yd³ |
| Or in 0.5 cu ft bags | 176 bags |
| Estimated cost (bulk, $30–$55/ton) | $137 – $251 |
| Area | 240 sq ft |
| Depth | 4 in |
| Waste allowance | 10% |
| Cubic feet | 88 ft³ |
| Density | 1.4 tons per yd³ (about 2,800 lb) |
| One ton covers at this depth | 58 sq ft |
#57 is washed, so it drains freely and never compacts into a hard crust. Under a driveway or patio it belongs on top of, or instead of, a compacting base only where drainage matters more than a firm surface. Bag counts are for 0.5 cu ft bags; bulk is usually cheaper above about half a ton.
#57 is the clean, washed three-quarter-inch crushed stone every quarry stocks and most drainage and base jobs call for. It weighs about 1.4 tons per cubic yard loose, so a ton covers roughly 58 square feet four inches deep. Enter the area and depth for tons, cubic yards, bags and a cost range, plus how far one ton goes at your depth.
About 1.4 tons, or roughly 2,800 pounds per cubic yard loose. Washed limestone #57 can run a little heavier and granite a little lighter, so check your quarry's figure if you are ordering by the ton for a large job.
About 58 square feet at 4 inches deep, 77 square feet at 3 inches and 116 square feet at 2 inches. A ton is about 0.71 cubic yards, or 19.3 cubic feet, and coverage is that volume divided by the depth in feet.
It is ASTM D448 size No. 57: stone that passes a 1 inch sieve almost entirely and is mostly retained on a No. 4 sieve (about 3/16 inch), so the pieces run from about 1 inch down to 3/16, most around 3/4 inch. That is why suppliers also sell it as 3/4 inch clean or 3/4 inch crushed stone.
About 39 bags of 0.5 cubic feet, because a ton of #57 is about 19.3 cubic feet. At typical bagged prices that is several times the cost of bulk stone, so bags make sense for small jobs like post holes, footing pads or a window well.
Drainage and clean base: French drains, pipe bedding, gravel pads under deck blocks and sheds, the drainage zone behind retaining walls, and a loose top layer on driveways. It is the wrong choice where you need a surface that locks hard — use crusher run for that.
