- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 384 × 0.250 = 96.0 cu ft.
- Cubic yards: ÷ 27 = 3.56 yd³.
- Tons: × 1.35 = 4.8 tons.

About #57 stone
Since #57 is washed and open-graded, it moves a little underfoot. Many installers put it over a compacted base of a dense-graded stone rather than straight on soil. 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. 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. 5.3 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 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 #57 stone fits
Works well for:
- 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 14x28 area at 2 inches takes about 3.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
