Bags of Crushed Stone for a 3x60 Walkway
How many bags of crushed stone for a 3x60 walkway: at 3 inches deep you need about 45.0 cubic feet, which is 90 bags of the common 0.5 cubic foot size. If your store sells crushed stone in 50-pound bags instead, figure about 94 bags, since crushed stone weighs roughly 104 pounds per cubic foot.
Volume and tonnage calculator →Bag count by depth
| Depth | Cubic feet | 0.5 cu ft bags | 50 lb bags (approx.) |
|---|---|---|---|
| 1 in | 15.0 | 30 | 32 |
| 2 in | 30.0 | 60 | 63 |
| 3 in | 45.0 | 90 | 94 |
| 4 in | 60.0 | 120 | 125 |
How to figure it
- Area: 3 × 60 = 180 sq ft.
- Volume: 180 × (3 ÷ 12) = 45.0 cu ft.
- Bags: 45.0 ÷ 0.5 = 90 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 45.0 cubic feet is 1.67 yards, about 2.3 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 90 against a bulk quote for 2.6 tons delivered.
About crushed stone
Most quarries sell crushed stone by a size number or a screen size. Clean crushed stone drains well; stone with fines packs harder but sheds water more slowly.
Before you spread for a walkway
- Dig and level. Remove sod and set the base slightly below the surrounding grade.
- Edge it. Steel, plastic or stone edging keeps material in place.
- Spread in layers. Rake to depth, then tamp or wet and compact.
- Buy a few extra. Grab 5 to 10 percent more bags for settling and touch-ups.

When to choose crushed stone
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Less suited to:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 12x24 area at 4 inches takes about 5.0 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
