How Much Sand for a 12x10 Patio?
A 12 by 10 foot patio is 120 square feet. How much sand for a 12x10 patio depends on depth: at 3 inches it is about 1.11 cubic yards or 1.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 12x10 patio
- Area: 12 × 10 = 120 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 120 × 0.250 = 30.0 cu ft.
- Cubic yards: ÷ 27 = 1.11 yd³.
- Tons: × 1.35 = 1.5 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.37 | 0.5 | 0.6 |
| 2 in | 0.74 | 1.0 | 1.1 |
| 3 in | 1.11 | 1.5 | 1.7 |
| 4 in | 1.48 | 2.0 | 2.2 |
About sand
Sand weight changes a lot with moisture. Damp sand can weigh noticeably more per yard than dry sand, so a ton of wet sand covers less area than the same ton dry. 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. 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. 1.7 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 sand fits
Good uses:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Think twice for:
- Driveway bases, since sand shifts under load
- Steep areas exposed to runoff
- Thick layers under pavers, which settle unevenly
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 15x30 area at 2 inches takes about 3.8 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
