How Much Crushed Stone for a 8x10 Patio?

How much crushed stone for a 8x10 patio is a quick volume problem. 80 square feet at 3 inches comes to 0.74 cubic yards. Crushed stone usually weighs about 1.35 to 1.5 tons per cubic yard, so plan on roughly 1.0 tons.

The math for a 8x10 patio

  1. Area: 8 × 10 = 80 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 80 × 0.250 = 20.0 cu ft.
  4. Cubic yards: ÷ 27 = 0.74 yd³.
  5. Tons: × 1.4 = 1.0 tons.

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. Weight per yard is a planning number; the scale ticket at the yard is the real one.

Preparing the patio

Remove sod, level the area with a slight slope away from the house, and lay landscape fabric if weeds are a concern. Edging keeps loose material inside the patio footprint. Since the patio carries foot traffic and furniture, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 1.1 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At about 1.0 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
  • Where it drops. Have the truck dump as close to the patio as firm ground allows.

Where crushed stone fits

Best suited to:

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

Think twice 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 10x20 area at 2 inches takes about 1.7 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
