How Much Crusher Run for a 8x10 Patio?

How much crusher run for a 8x10 patio: at 3 inches deep you need about 0.74 cubic yards, which is roughly 1.1 tons at 1.55 tons per yard. The patio covers 80 square feet, so every inch of depth adds about 0.25 yards.

The math for a 8x10 patio

Area: 8 × 10 = 80 sq ft.
Depth in feet: 3 ÷ 12 = 0.250 ft.
Cubic feet: 80 × 0.250 = 20.0 cu ft.
Cubic yards: ÷ 27 = 0.74 yd³.
Tons: × 1.55 = 1.1 tons.

The volume and tonnage calculator does this for any size.

About crusher run

Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

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. For foot traffic and furniture, the depths in the table above are a reasonable starting range.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 1.3 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 1.1 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.

Good and poor uses for crusher run

Good uses:

Base under asphalt, pavers or concrete
Gravel drives that need a firm, packed surface
Shed pads and equipment pads

Poor fit for:

Drainage layers, since the fines slow water
Decorative beds
Spots where you want water to soak straight through

Quick reference numbers

Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.8 tons.
Another size for comparison: a 14x28 area at 4 inches takes about 7.5 tons.
Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
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.
