Volume and tonnage calculator →The math for a 14x10 patio
- Area: 14 × 10 = 140 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 140 × 0.250 = 35.0 cu ft.
- Cubic yards: ÷ 27 = 1.30 yd³.
- Tons: × 1.35 = 1.8 tons.
The volume and tonnage calculator does this for any size.
#57 stone needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

| 3 in | 1.30 | 1.8 | 1.9 |
| 4 in | 1.73 | 2.3 | 2.6 |
| 6 in | 2.59 | 3.5 | 3.9 |
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. 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. 1.9 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
Good uses:
- 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 15x30 area at 4 inches takes about 7.5 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
