Volume and tonnage calculator →The math for a 10x30 patio
- Area: 10 × 30 = 300 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 300 × 0.250 = 75.0 cu ft.
- Cubic yards: ÷ 27 = 2.78 yd³.
- Tons: × 1.35 = 3.8 tons.

About #57 stone
#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself. 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. 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. 4.1 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 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.
Good and poor uses for #57 stone
Best suited to:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Think twice for:
- A standalone base, since it does not pack hard without fines
- Paver setting beds
- Walk paths meant for strollers or wheelchairs
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 12x24 area at 4 inches takes about 4.8 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
