How much crushed stone for a 16x30 patio: at 3 inches deep you need about 4.44 cubic yards, which is roughly 6.2 tons at 1.4 tons per yard. The patio covers 480 square feet, so every inch of depth adds about 1.48 yards.
Volume and tonnage calculator →The math for a 16x30 patio
- Area: 16 × 30 = 480 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 480 × 0.250 = 120.0 cu ft.
- Cubic yards: ÷ 27 = 4.44 yd³.
- Tons: × 1.4 = 6.2 tons.

Crushed stone needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

| 3 in | 4.44 | 6.2 | 6.8 |

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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
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. This patio sees foot traffic and furniture, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 6.8 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 this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the patio as firm ground allows.
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 8x16 area at 3 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
