Bags of Crushed Stone for a 6x60 Walkway

How many bags of crushed stone for a 6x60 walkway: at 3 inches deep you need about 90.0 cubic feet, which is 180 bags of the common 0.5 cubic foot size. If your store sells crushed stone in 50-pound bags instead, figure about 187 bags, since crushed stone weighs roughly 104 pounds per cubic foot.

How to figure it

  1. Area: 6 × 60 = 360 sq ft.
  2. Volume: 360 × (3 ÷ 12) = 90.0 cu ft.
  3. Bags: 90.0 ÷ 0.5 = 180 bags (round up).

Bags or bulk?

A cubic yard is 27 cubic feet, so 90.0 cubic feet is 3.33 yards, about 4.7 tons. At this size, a bulk delivery usually beats a cart full of bags once you count trips. Compare the bag price × 180 against a bulk quote for 5.1 tons delivered.

About crushed stone

Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size.

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.

The volume and tonnage calculator handles other sizes and depths.

Where crushed stone fits

Works well for:

  • Driveway top courses and parking pads
  • Shed and hot tub bases
  • Backfill behind walls when a clean size is used

Poor fit for:

  • 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 15x30 area at 2 inches takes about 3.9 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.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
